    Hi @DKulkar Yes, user calibration is supported for every device, including ADP3X50.

    Hi @ysrevol You could import the WF (SDK) C API in LabVIEW, or write a custom app or library which controls the device and call this from LV.

    Hi @Hannes See the WF SDK/ samples/ py/ AnalogImpedance_Analyzer.py and other examples

    Hi @Mavitaka The interpreter is available in the WaveForms application. For custom app/script interpreter a loop can be used, looking for rising edge of the respective clock bit of the sample and storing masked value of the next sample, for 400MHz rate to have 2.5ns delay.

    Hi @ysrevol With the C API, see WF SDK/ samples/ py/ DigitalOut_Pulse.py

    Hi @J R In the initialize VI specify the device serial number like: "SN:210415123456" or rename the device with WaveForms application like Discovery3A/B and use that in initialize.

    Hi @Analog The Tracer tool takes control over Scope and two Wavegen channels. When used with the Transistor Tester Adapter it also controls the Supplies and Static IO. The automation can be done using the Script tool. For export use like: Tracer.Export("~/Documents/trace"+index+".csv", "Trace") If you control the instruments separately you can export the Scope XY view like: Scope.Export("~/Documents/xy"+index+".csv", "XY1")

    Hi @Old Printer The application supports some touch interactions but it is not thoroughly optimized for such. After the following post it was tested and improved.

    Hi @prudhvichitturi There is no horizontal quick measure but I can add such, and also more options for persistence.

    Hi @prudhvichitturi Horizontal and vertical cursors, and quick measure should be available. Which software version are you using ?

    Hi @Xiaohu The Scope/ Time/ Options/ Sampling/ Clock available with most of the devices (AD1,2,3...) is just a sampling condition which can be asynchronous to the ADC. Real reference clock IO is available for AD3, ADP3X50

    Hi @Effedipi The pulls by default are not enabled and are not activated in the example script either.

    Hi @Ergest See the following example: AnalogOutIn_PlayRecord2.py Your posted code is not complete, it can't be run as it is. Some observation: line 55 the preceding configure is reset by FDwfAnalogOutReset, line 94 there is no need to reconfigure/restart FDwfAnalogOutConfigure

    Hi @Effedipi Change the lines 24+ to: print("Opening first device") dwf.FDwfDeviceOpen(c_int(-1), byref(hdwf)) # device configuration of index 3 (4th) for Analog Discovery has 16kS digital-in/out buffer #dwf.FDwfDeviceConfigOpen(c_int(-1), c_int(3), byref(hdwf))

    Hi @Md Fahim Al Fattah See the following for WaveForms Dual device control https://digilent.com/blog/extending-channel-counts-by-using-dual-mode/ You can also find 4 channel devices: https://digilent.com/reference/test-and-measurement/start

    Hi @Simon Koops The Coolrunner II has onboard USB-JTAG programmer which can be used with Adept app. The Digilent USB-JTAG programmers can also be used with Adept app to program it.

    Hi @MarcosOrzari Probably the powering through USB is insufficient. Try using other USB port, powered hub, auxiliary 5VDC supply or other computer. The latest software version has additional detection for such situations.

    Hi @AD2 User The Windows Device Manage refreshed automatically, or with the "Scan" tool button in front, or Action/ Scan for... This is strange since the LED in the AD2 only activated, starts flashing after software/application connection, after the device is detected, 'firmware' download and configuration. Have you tried the device with another computer ?

    Hi @Yami Using the Logic Detector as trigger source, the trigger to out delay is 180ns DIO-0 33MHz input and DIO-1 20ms output Wiring the 33MHz signal to trigger input, the trigger to out delay is 110ns

    Hi @Effedipi Play&Record from file is the AnalogOutIn_PlayRecordStereo.py
  21. attila
    Hi @Effedipi For up to digital-out device buffer size samples (32768 for DD) the simpler method can be used like in DigitalIn_Acquisition.py DigitalOut_Custom.py ... examples For more samples with Digital Discovery see WF SDK/ samples/ py/ DigitalDiscovery_PlayRecord.py ...
  22. attila
    Hi @Ergest FDwfAnalogOutNodeFrequencySet for standard and custom signals expects waveform frequency and not sample rate, you probably want c_double(fs/cSamples) FDwfAnalogOutRepeatSet for existing devices it supports value up to 32768 or use 0 for infinite repeat

    Hi @Hellsmoke See the following example test1.py and the manual and the other available examples.

    Having a powerful external supply with common computer GND/0V and (accidentally) connecting a supply output to AD2's GND will be a short circuit that can damage the device.
  25. attila
    I think the current min/max (peak) sampling is sufficient.
