[Waveforms App and Libraries unsigned on Mac OS X]

Hi @fractalbrain

I'm working on this problem.

[Transistor tester & emitter voltage]

Hi @Daniel M

The device AWG outputs +/-5V and by brining the emitter (virtual ground) to -/+5V it lets you test the components in 0.. +/-10V range. This is default option with Adapter.

Hi @asdfex

Use View/Zoom or Mode: Record to have fixed capture rate and position.

[New Analog Discovery 3 - Error on Waveforms Startup - Analog CIrcuit of the Device is turned off. CDCE Not Locked. PLL Not Locked]

Hi @chris.h

It is possible the power supply overcompensates the inrush current during powerup, causing a voltage spike that exceeds the allowed upper threshold of the device.

[Persistence when displaying multiple waveforms cuts off and displays only 5-7 waveforms.]

Hi @JonD

The specified width/height are used in building the persistence image/table, to have control over export size or shift steps.
For visualization, the persistence image is stretched to the available view size.

Hi @chris.h

The AUX input has under/overvoltage protection.
I get the same error if I try to supply the AD3 with almost 5.5V

[Generating Burst Signals from Wavegen Using Code]

Hi @HasNoCreek

You can set the run time to be 5 times the pulse length so the pulse will output 5 times during one run step.
The trigger PC is useful to synchronize multiple internal/external instruments. If the only task is to generate the pulses you can start the AWG for each burst with the config function.

Hi @JonD

Press clear or stop/run again to apply the new size.
The next version will auto-clear on size adjustment.

[WaveForms, AD3 and Scope Trigger]

Hi @sng2024

This rather appears to be a connection issue on the first test, of 1- not making contact.

[Logic analyzer custom protocol script problem]

Hi @leodom

The next version (v3.22.11) will pass the rgData in native JavaScript 64bit float data type with 54 bit fraction.

The bit operations seem to be performed as 32 bit signed value, so these need to be handled with care above 31 bit, like: add, divide, divrem... instead of: or, shift, mask...

Thank you for your post.

[Persistence when displaying multiple waveforms cuts off and displays only 5-7 waveforms.]

Hi @JonD

Set fixed height and adjust shift. Like here with 201 pixel Height and 1 ShiftY, the midpoint to bottom will show 100 captures.

[Recording 4 UART Signals at the same time.]

Hi @Sam_DAero

You can have multiple Logic Analyzer interfaces open but a device has only one such resource, so only one interface can be active at a time.
The Logic Analyzer can record up to 256Mi samples and the Protocol 'unlimited'

[Recording 4 UART Signals at the same time.]

Hi @Sam_DAero

Currently the Protocol/UART/Spy supports two UART channels.
The next version will support 4 lines. I'm working on it.

[Can I perform cyclic voltammetry using Analog Discovery 2?]

Hi @Preyojon Dey

It could be probably done with Wavegen and XY view.
See the device specification to see if it meets your measurement requirements.

[Effect of activating option Ib/Vbe when using transistor tester with WaveForms Tracer]

Hi @linear_guy

It does if you measure Ib. The scope channel 1 differentially measures Ib = C1/Rb

[Define record time for Oscilloscope in Waveforms SDK]

Hi @gabagool

If you want to capture up to device buffer size see AnalogIn_Acquisition.py example and for more at lower rate use data streaming, see AnalogIn_Record.py or other similar examples.

[I2C Error Conditions]

Hi @RoboRepublic

It would be interesting to see the signal transitions after stop, what causes error to be displayed backwards up to stop. It is probably a timing issue with the next start.

[Effect of activating option Ib/Vbe when using transistor tester with WaveForms Tracer]

Hi @linear_guy

No, it does not calculate since that would be an assumption.
All voltage and currents are measured with 4 scope channel devices and with Analog Discovery Adapter. This uses two sweeps and relays to measure each parameter. AD without adapter can measure 2 parameters at a time.

[Scope to Digital Option Question]

Hi @jcorleto

1,2,3,4: yes
These are application features available with any supported device.

[Sine Sweep Waveform Generation in Python]

Hi @Saeed Zohoori

The AM/FM buffer on AD1,2 is 2k sample 9bit and newer devices AD3,ADP3X50,ADP2230 is 2k-16k sample 16bit
The deeper and higher resolution gives smoother AM/FM but even the AD2 should be much better than your plot.
Even with 9bit the frequency step for 50-500Hz should be ~0.8789Hz = (500Hz-50Hz)/512, like it is measured here:

Hi @Hazardsneon

I don't understand this. Can you attach a screenshot ?

It doesn't allow me to grab the 256i at 1 sec but it adjusts the number of samples if you adjust the time base to a number that doesn't make sense.
