[Logic Detector as trigger in Scope. Is it possible?]

Hi @m72

Thanks for the observation. Fixed for the next version.

[Noise on Channel 1 - Analog Discovery Pro]

Hi @Piotr

Is it working now correctly ?
Looking at this again, to be able to set the trigger level to 30V with 0V offset, you probably have also set 10x? Attenuation for Channel 1, so signal and noise are both visually amplified, with 10X you have 500Vpk2pk range.

[Adjust Digital IO system frequency in Python API]

Hi @Steve_3

The PLL has a fractional option for finer frequency synthesis. This is not used since it introduces jitter which can affect the ADC and DAC performance. Depending on use, like for digital signals it could be acceptable. If you need this, I could try enabling it next week.

[Adjust Digital IO system frequency in Python API]

Hi @Steve_3

On AD3 the supported frequencies are limited by the device PLL and its 25MHz reference clock.
To obtain other frequencies external reference clock can be supplied through trigger 1 IO, with 10.42MHz ref clock it can generate 83.36MHz

A distribution of the supported frequency steps looks like this, 50-125MHz

Hi @iPsych

Yes. There is no need to reprogram, Virtual Bench can be used with newer version of WaveForms:

 

[IV Sweep for MOSFET on Analog Discovery 3]

Hi @Anirud Durani

You could use the following adapter which has support in WaveForms application 'Tracer' instrument.
https://digilent.com/reference/test-and-measurement/transistor-tester-adapter/start

The Scope and AWG instruments can also be used for IV curves and for most of the devices the Power Supply IOs can be used as slow AWG, like for for higher drain current.

API is available for all T&M devices.

[Analog Discovery 3 Custom Waveform and Continuous Clock]

Hi @Empower

Pad the custom pattern with 1s, like it is done here in the app:

 

If the 2048 samples provided by the default (1st) configuration are not sufficient use the 5th (index 4) device configuration.
If you want to keep the custom pattern in phase with the clock, make sure to configure multiple of periods:
custom samples / custom frequency = N / clock frequency, like 2000/100MHz = 20/500kHz

 

You can use the following parameter to keep the device running after software close, application exit:
dwf.FDwfParamSet(DwfParamOnClose, c_int(0)) # 0 = run, 1 = stop, 2 = shutdown

Probably you have a very old digilent.waveforms installed without this function. You can find the latest software at:

[Help Needed: Configuration Issues with Analog Discovery 2 Units]

Hi @pieb

This usually indicates USB supply or cable contact problem.
Try using the original USB cable or other cables you have at hand, try other USB sockets or computer, powered hub or 5V DC auxiliary supply...

[Logic analyzer custom protocol script problem]

Hi @s4msepi0l

Please split the values and use different flags.
I don't want to make the values larger, since this would increase memory usage, would be slower, above 52bits incompatible with the Script tool...

[SAE J1850 VPW protocol decoder]

Hi @TOIVI

[Noise on Channel 1 - Analog Discovery Pro]

Hi @Piotr

Notice that warning "Channel 1 range will be extended !"
You have set the trigger to C1 30V, so the C1 is set to high range 50V pk2pk (lower resolution) and the other channels are at low range (higher resolution).
The channel range is adjusted not only by the specified Range but also according the trigger level if needed to make sure it captures that value and it switches also to higher range if offset exceeds +/-1V. See the Help tab / ADP3450

The next software version will also bring channel option for Impedance Analyzer.

[SAE J1850 VPW protocol decoder]

Hi @TOIVI

Thanks for sharing this. I'll add to support it natively.

Edit:
Instead of:
if ((Symbol == 7) || (Symbol == 7)){ //SOF or EOD
you probably wanted:
if ((Symbol == 6) || (Symbol == 7)){ //SOF or EOD

I thank you for your contribution.

The next application version will add support for serial ports, so from Script you can communicate through COM ports.

[GPIB communication in AD3450]

Hi @3D_loves_eng

With WaveForms Script tool external applications can be accessed, see Tool.exec/start functions, so you could call the USB/GPIB command app (if such exists) to send commands.

The WaveForms app supports controlling any device + DPS (or two identical devices), so you can control ADP3450 and DPS3340 from the same application.
With custom app/script multiple devices can be controlled.

Thanks for the observation. I forwarded it to the people in charge.

Hi @nurber3

See the pulse timeout trigger.

[Latest beta missing trigger "Type:" at 200% Scale on Ubuntu 20.04 LTS, appears at 100% scaling]

Hi @nurber3

The reason for switching to a single row toolbar is to have more usable screen space.
The further trigger options are available in the dropdown.
The trigger level can also be adjusted by drag on the right side or level arrow, hysteresis with scroll on right or by the half arrows, the position on top or bottom, length and holdoff by half arrows.
