PicoLog® 1000 Series Multipurpose data acquisition

Designed to meet the needs of a wide range of general-purpose voltage, sensor and transducer logging applications, the PicoLog 1000 Multichannel DAQ Series features independent software-configurable scaling and control outputs, an external terminal board for custom front-end circuitry and a choice of 10 or 12-bit input resolution.

 

Multichannel data acquisition (DAQ):

  • Up to 16 input channels per data logger
  • Up to 4 output channels per data logger
  • Use up to 20 data loggers at the same time
  • Up to 1 MS/s sample rate
  • USB connected and powered
  • Data acquisition software and SDK included

A distinguished pedigree:
The PicoLog 1000 Series is the result of a distinguished lineage that goes back to the release of our first multichannel data logger—the ADC-11—in 1993. The original ADC-11, and its successor the USB ADC-11, proved to be the perfect choice for users wanting a low-cost way to measure and record multiple signals. The PicoLog 1000 Series builds on this success to give you the same low-cost data acquisition but with greater power and performance. (Because the ADC-11 was so popular we’ve also added a USB ADC-11 compatibility mode which allows you to use your PicoLog 1000 logger as a direct replacement to the USB ADC-11.)

An expandable multichannel data acquisition system:

The budget model PicoLog 1012 has 12 input channels and 10 bit resolution. The powerful PicoLog 1216 has 16 channels and 12 bit resolution. Need more channels? No problem. Using the new PicoLog 6 software you can connect up to 20 Pico data loggers to one PC—giving you a potential 320 channel PicoLog 1000 Series data acquisition system, or the ability to use your PicoLog 1000 logger with other devices such as the USB TC-08 Thermocouple Data Logger.

External Terminal Board:

The external terminal board has screw terminals to allow sensor wires to be attached to the data logger without soldering. The terminal board also has locations where you can fit resistors to offset and extend the input ranges of the logger.

Fast and accurate:

With 10 or 12-bit resolution and multiple sampling modes, a PicoLog 1000 Series logger will meet your data logging needs. The PicoLog 1000 Series has 3 sampling modes: Streaming mode allows channel voltage readings to be logged continuously at up to 100 kS/s, while block mode captures up to the full 1 MS/s sample rate of the logger for a duration limited by the 8000 sample buffer, both these speeds applying to single-channel operation.

PicoLog 6 – straightforward from the start

Designed from the ground up to be intuitive from the outset, PicoLog 6 allows you to set up the logger and start recording with just a few clicks of the mouse, whatever your level of data logging experience.

From here, starting a capture is simple: plug in the logger, add a channel, press Record, and you’re logging! PicoLog 6 also includes a number of additional features to cater for more advanced data logging needs. 

Easy navigation

A simple vertical menu bar on the left of the screen provides permanent access to the main program menus and view modes of PicoLog 6 without pausing capture. 

The permanent vertical navigation bar gives access to the following menus:

  • Device setup and capture menu
  • Saved file browser menu
  • Program settings menu
  • Help menu

The device setup and capture menu

Within the Device setup and capture menu are Device configuration view, Graph view and Table view providing a visually smart way to set up and acquire data from a multichannel acquisition system, even with multiple different PicoLog data loggers and PicoScope oscilloscopes with hundreds of channels enabled and logging.

Device configuration

In the Device configuration view you can instantly see the status of instruments, acquisition channel setting and math channel setup. An image of the device appears for each device detected, showing which channels are enabled. Device configurations can simply be moved or copied to aid larger multi-instrument configurations, swap out devices during capture or share configurations.

From this screen you can view and adjust settings such as adding graph axes, per-channel scaling factor, alarms, notes, graph annotations, channel naming and color, sample mode and sample interval. 

View live data in Graph view

Viewing your data in a graph is fundamental to data acquisition applications. The PicoLog 6 graph view makes it easy to view captures, zoom and pan through large datasets, record alarm history and display when alarms occurred. It also allows you to annotate the graph with your notes and observations.

Adding additional graph axes is also essential for multi-channel logging applications where measurement units are different for every channel, or when the channels are measuring values at opposite ends of the range. For example, simultaneously measuring an internal furnace temperature of over 1000 °C and the ambient temperature at the same time requires two axes so that the detail of both is visible. You can view up to four axes with different ranges at a time.

View live numerical data in table format

Table view is a really useful new feature which allows you to view your tabulated numerical data in a spreadsheet format. Table view is not only available to view live data from your current dataset, you can also view tabulated data in your saved data files.

When configuring table view, it is possible to add 4 statistical parameters to each channel, choose from; last sample, minimum, maximum and average. In addition, the output sample rate must be specified allowing you to define the frequency that table rows are calculated.

Setting up Channels and Axes

The Channel and Axes settings menu is visible in both the Device settings and Capture Graph views. Once a channel is enabled and settings confirmed, you can view its connection status at a glance, along with alarm condition and current live measurement. In this menu, you can also configure alarms and view graph annotations and capture info.

Alarms and annotations

Maybe you’re measuring the temperature of a microbiological culture in an incubator, or strain on a concrete bridge in high winds; you’ll need to be informed when a reading exceeds acceptable tolerances.  In PicoLog 6, you can set up an alarm to alert users when a parameter goes out of range. This can be configured to play a sound, display visual alerts on the screen, run a specified application such as an email or SMS client, and automatically annotate the capture graph to mark when the alarm happened and its duration.

PicoLog 6 alarms can also trigger a digital output on devices with supporting hardware, such as the PicoLog 1000 Series, ADC-24 and DrDAQ. You can even trigger a digital output from one of these devices based on an alarm condition from another connected logger without digital outputs, such as a TC-08.

Math channels

Some applications require the recording and graphing of a calculated parameter containing data from one or more measurement channels. PicoLog 6 is equipped with an equation builder to perform simple calculations such as A – B, or more complex functions such as log, sqrt, abs, round, min, max, mean and median. Math channels are treated like any normal channel, so you can perform functions like alarms, graphing and annotations on them. 

Robust data file format

At the heart of PicoLog 6 is the file system which stores live capture data directly to a robust database, rather than to a single file that is prone to data loss and corruption. If the computer is shut down and rebooted, PicoLog will only lose the data during the outage and the file system will begin saving capture data once again without corruption of the file.

The file system also allows for virtually no limit on the size of dataset you can capture – only the size of the hard disk on your computer!

Another major step forward is native support for 32-bit and 64-bit Windows, various Linux distributions (64-bit only) and macOS. The new .picolog file format is compatible across all operating systems. Since anyone can download and install PicoLog 6 for free, you can share saved .picolog files with co-workers, customers and suppliers for offline post-analysis.

Exporting data

When you’re ready to export the data, you have several options. First, save the .picolog file and close the acquisition. You can save files with custom search tags to make them easier to categorize and locate later.

Exporting large datasets to CSV can often be troublesome due to file size limitations, so PicoLog 6 includes a suite of export options to narrow down the size of the whole dataset. These include downsampling, selecting channels to export or even restricting the export region to the zoomed area on screen.

Want to export a screen shot? PicoLog 6 includes a feature to export the graph as a PDF: again, select either the entire capture or the zoomed area of interest. The export to PDF format also includes options to include alarm trigger history, annotations, channel configuration and capture notes, for a complete capture report.

PicoLog data loggers now support Raspberry Pi computers

Pico Technology data loggers work great when USB connected to PCs running Windows, macOS and Linux, and now with support for Raspbian OS on armhf processors, we now support Raspberry Pi computers.

Optimized and tested on the new Raspberry Pi 4, and the current 3B and 3B+ on Raspbian Stretch, the PicoLog 6 data logging software package provides a visual, easy-to-use interface allowing you to quickly set up simple or complex acquisitions and record, view and analyze data. It’s the same fully functioning software that runs on Windows, macOS and Linux.

Coupled with a Raspberry Pi, this new PicoLog 6 package expands the flexibility and opens the door for Pico’s data loggers to be used in new and different ways:

  • You can now connect the logger to the Pi and remove the keyboard, mouse and video to make an inexpensive stand-alone logger storing its captured data locally on a Pi SD-CARD
  • Furthermore, connecting your Pi by WiFi or Ethernet, you can internet-enable your Pico logger which you can then access remotely using an open-source VNC server and viewer freely available
  • …and better still, utilising the Power over Ethernet (PoE) capability on the Raspberry Pi 3B+ paired with the PoE PiHAT not only eliminates the need for an external power supply and powered USB hub, it also internet-enables your logger at the same time

PicoScope Software

Advanced display

PicoScope software dedicates almost all of the display area to the waveform. This ensures that the maximum amount of data is seen at once. The viewing area is much bigger and of a higher resolution than with a traditional benchtop scope.

With a large display area available, you can also create a customizable split-screen display, and view multiple channels or different views of the same signal at the same time. As the example shows, the software can even show multiple oscilloscope and spectrum analyzer traces at once. Additionally, each waveform shown works with individual zoom, pan, and filter settings for ultimate flexibility.

The PicoScope software can be controlled by mouse, touchscreen or keyboard shortcuts.

 

FFT spectrum analyzer

FFT spectrum analyzer

The spectrum view plots amplitude vs frequency and is ideal for finding noise, crosstalk or distortion in signals. The spectrum analyzer in PicoScope is of the Fast Fourier Transform (FFT) type which, unlike a traditional swept spectrum analyzer, can display the spectrum of a single, non-repeating waveform.

A full range of settings gives you control over the number of spectrum bands (FFT bins), window types, scaling (including log/log) and display modes (instantaneous, average, or peak-hold).

You can display multiple spectrum views alongside oscilloscope views of the same data. A comprehensive set of automatic frequency-domain measurements can be added to the display, including THD, THD+N, SNR, SINAD and IMD. A mask limit test can be applied to a spectrum for automated testing.

More information on Spectrum analyzer >>

 

waveform buffer

Waveform buffer and navigator

Ever spotted a glitch on a waveform, but by the time you’ve stopped the scope it has gone? With PicoScope you no longer need to worry about missing glitches or other transient events. PicoScope can store the last ten thousand oscilloscope or spectrum waveforms in its circular waveform buffer.

The buffer navigator provides an efficient way of navigating and searching through waveforms, effectively letting you turn back time. Tools such as mask limit testing can also be used to scan through each waveform in the buffer looking for mask violations.

More information on Waveform buffer >>

 
PicoScope color persistence mode

Digital persistence modes

Advanced display modes allow you to overlay thousands of waveforms. New or more frequent data can be displayed in a brighter color or shade. This makes it easy to see glitches and dropouts and to estimate their relative frequency. Choose between analog persistence, digital color or custom display modes.

More information on Persistence modes >>

 

Custom probes in PicoScope oscilloscope software

The custom probes feature allows you to correct for gain, attenuation, offsets and nonlinearities in probes, sensors or transducers that you connect to the oscilloscope. This could be used to scale the output of a current probe so that it correctly displays amperes. A more advanced use would be to scale the output of a nonlinear temperature sensor using the table lookup function.

Definitions for standard Pico-supplied oscilloscope probes and current clamps are included. User-created probes may be saved for later use.

More information on Custom probes in PicoScope oscilloscope software >>

 

Alarms

PicoScope can be programmed to execute actions when certain events occur.

The events that can trigger an alarm include mask limit fails, trigger events and buffers full.

The actions that PicoScope can execute include saving a file, playing a sound, executing a program or triggering the signal generator / AWG.

Alarms, coupled with mask limit testing, help create a powerful and time saving waveform monitoring tool. Capture a known good signal, auto generate a mask around it and then use the alarms to automatically save any waveform (complete with a time/date stamp) that does not meet specification.

 

oscilloscope maths channels and filters

Math channels and filters

On many oscilloscopes waveform math just means simple calculations such as A + B. With a PicoScope it means much, much more.

With PicoScope 6 you can select simple functions such as addition and inversion, or open the equation editor to create complex functions involving filters (lowpass, highpass, bandpass and bandstop filters), trigonometry, exponentials, logarithms, statistics, integrals and derivatives.

Waveform math also allows you to plot live signals alongside historic peak, averaged or filtered waveforms.

You can also use math channels to reveal new details in complex signals. An example would be to graph the changing duty cycle or frequency of your signal over time.
