WaveForms<\/a>\u00a0is the software interface that controls most of Digilent’s test and measurement devices, including the\u00a0Analog Discovery 2<\/a>,\u00a0Digital Discovery<\/a>, and\u00a0Electronics Explorer Board,\u00a0<\/a>providing access to and enabling all of their analog and digital Instruments. We posted an updated version of WaveForms, version 3.9.1,\u00a0<\/strong>which is available for download on the WaveForms Resource Center and at AnalogDiscovery.com<\/a>. This update to WaveForms provides additional functionality that will be outlined in this post and includes bug fixes! If you want to know what version you have,\u00a0check out this post.<\/a><\/p>\n

You can view the entire change log on the\u00a0WaveForms Download page<\/a>, but here is a summary of the biggest changes.<\/p>\n

New Oscilloscope Features:<\/strong><\/p>\n

In the Oscilloscope instrument, additional math channels can be added to script\u00a0math functions on the acquired oscilloscope data. The Math Channel window now has examples, including current calculations, power calculations, energy, and power.<\/p>\n

\"\"<\/a><\/p>\n

 <\/p>\n

Each additional channel that gets added may have a different y-axis\u00a0scale and units. Now in addition to being able to apply different scales and units multiple scales can now be displayed at the same time on the left-hand side of the oscilloscope chart.<\/p>\n

\"\"<\/a><\/p>\n

Above the various channel boxes under the options menu,\u00a0 an additional setting called “zero offset” has been added. This will allow a quick calibration of the Oscilloscope\u00a0if needed.<\/p>\n

\"\"<\/a><\/p>\n

User Interface improvements in the Logic Analyzer:<\/strong><\/p>\n

Previously the logic analyzer and Pattern Generator graphs provided black traces for each digital channel added. The gear menu now provides the option to change the color of the traces for enhanced readability.<\/p>\n

\"\"<\/a><\/p>\n

When adding a BUS, I2C, I2S or SPI interpreter to the Logic Analyzer the format menu now includes ASCII as an additional display option for the interpreted data.<\/p>\n

\"\"<\/a><\/p>\n

 <\/p>\n

Additional features added to the Spectrum Analyzer:<\/strong><\/p>\n

The Spectrum Analyzer now allows exporting and importing of time domain samples in addition to trace data.<\/p>\n

\"\"<\/a><\/p>\n

Network Analyzer Improvements:<\/strong><\/p>\n

The Magnitude box now has an additional drop-down that allows specific spectrum measurements to be configured and show on the plot in the Network Analyzer.<\/p>\n

\"\"<\/a><\/p>\n

Additional improvements to the Network Analyzer include adding a FFT view to the additional plots available in the view menu, averaging,\u00a0 and an additional available unit for the traces, percentage.<\/p>\n

An additional Impedance Analyzer setup option:<\/strong><\/p>\n

There is now an additional circuit setup option in the Impedance Analyzer, taking advantage of differential scope inputs, where the reference resistor is in between the Positive and negative leads of channel two of the Oscilloscope and the device under test is in between the\u00a0positive and negative leads of channel one.<\/p>\n

\"\"<\/a><\/p>\n

Additional functionality in the Protocol Analyzer:<\/strong><\/p>\n

The CAN protocol analyzer now allows filtering by ID, and the I2C protocol analyzer will filter glitches based on a specified frequency in SPY mode.<\/p>\n

\"\"<\/a><\/p>\n

 <\/p>\n

SPI and I2C data in the protocol analyzer can now be displayed in Hexadecimal, Decimal, Binary, or ASCII.<\/p>\n

\"\"<\/a><\/p>\n

Additional Functions in WaveForms SDK:<\/strong><\/p>\n

Impedance Analysis is now built in to WaveForms SDK with the added AnalogImpedance function.<\/p>\n

\"\"<\/a><\/p>\n

WaveForms SDK is now updated to Python 3.0!<\/p>\n

\"\"<\/a><\/p>\n

Python examples can be found in the WaveForms SDK folder under sample\/py. There is also a Python example using Jupyter Notebooks at testandmeasure.org<\/a>.<\/p>\n

Additional Device Options:<\/strong><\/p>\n

In the bottom right corner of the application between the device name and the device status there is a menu of device options. These options now include changing the LED Brightness on the Digital Discovery, and the option to keep running, stop, or shutdown the device upon closing the application.<\/p>\n

\"\"<\/a><\/p>\n

Notes View:<\/strong><\/p>\n

Under the view menu in most of the instruments, you can now add a notes window, which opens a text editor that will be saved in the workspace. In the screenshot of the impedance analyzer farther up in this post you’ll see the notes view used to show the circuit setup.<\/p>\n

\"\"<\/a><\/p>\n
