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

Hi @linear_guy

Have you actually changed the base resistor ?

Here is R1 with 1k and Trace with 10k Rb

[Logging/Recording SPI Bus]

Hi @LarryMerino

The 'Record to File' captures raw data up to 'unlimited' length which needs to be processed by external application.
Use the Mode:Record for longer capture and you want processing in the WaveForms application.
Use the Protocol tool if you are interested only in one UART,SPI,I2C,CAN,CEC,JTAG or SWD protocol data.

[Why don't curve trace units match the spec sheets?]

Hi @electricbungaloo

The base is controlled in voltage and not current.
For 3mA over 10k it would need 30V and also ~300mA on collector, but the device can provide up to 10V and 30mA.

[no voltage]

Hi @LifesLesson

Under Settings/ Device Manager/ Calibrate/ Reset/ Load Factory
Connect W1 to 1+ and W2 to 2+ (connect 1- and 2- to any GND), generate signals and make some screenshots.

 

[New state appear after ADP3250 firmware upgrade]

Hi @Danny Cote

I called state 6 NoDone, before capture Done but still transferring data, which you can consider as Triggered.

Hi @Saeed Zohoori

See the AnalogOut_Sweep.py example

[System Frequency Response using 410-394 Benchtop O-scope]

Hi @TheRad

Have you also considered Analog Discovery 3 ?
If you have any specific test setup I could perform this to show you the operation or result.

This is an old topic for low frequency:

 

[how to log 2 SPIs simultaneaously in the protocol window with Digital Discovery]

Hi @samuel.cregut

The Protocol tool can log a single SPI or multiple CSs and MISOs. The Logic Analyzer can have multiple interpreters but this works on captures so it is not continuous.
The following script logs 2 SPIs to text files: DigitalIn_Spi_Spy2.py

[Feature request Logic Analyzer instrument]

Hi @PaulGlass

Could you explain what trigger condition you need ?

[Logging/Recording SPI Bus]

Hi @Hazardsneon

Some screenshots would be helpful.

[USB Recovery?]

Hi @Conrad2468

Press Boot, select Standard, Rename if you want.

[Recommended Version of Python for SDK]

Hi @Caleb Messerly

There is no recommended Python version.

 

[What is "Counter" in the Scope app?]

Hi @bryan78

Yes. The Counter is supported by Digital Discovery in Logic Analyzer.
This topic was about Scope Counter and the DD does not have Scope.

[What is "Counter" in the Scope app?]

Hi @bryan78

ADP5 is VirtualBench for which I cannot change the firmware.

[Frequency-dependent sweep levels for network analyzer]

Hi @clb

Right now I'm focusing on testing/fixing to prepare for a release, but probably next week will try improve the table editor.

[Can Analog Discovery 3 do most, if not all, of it's features at the same time?]

Hi @Akhilles

You can have multiple software instruments open but those sharing a common device resource (oscilloscope, logic analyzer,... and wavegen channels) cannot run at the same time, like Network Analyzer instrument uses oscilloscope resource and optionally 1 or 2 or no wavegen channel.

[What is "Counter" in the Scope app?]

Unfortunately the AD2 FPGA logic is full, such feature would not fit in the device.

[What is "Counter" in the Scope app?]

Hi @Kabron

It is not supported by AD2, only AD3, ADP3X50, ADP2230...

[Waveforms App and Libraries unsigned on Mac OS X]

Hi @fractalbrain

As visible in the screenshot 3.21.32 but other versions should also work.
If you open the application from the disk image Mac warning is probably shown each time. If copied to computer, drag&drop to Applications, only once and it should also launch faster since the disk image is compressed.

[What is "Counter" in the Scope app?]

Hi @Kabron

What device are you using ?
This shows trigger counter/timer measured in the device while the instrument is running.

[Add low pass filter to analog input for AD2 in WaveForms SDK]

Hi @Ammar Kh

Yes, the filter channels are performed in the hardware. Note these are optimized for high frequency, the FIR has only 16 taps.

[How to trigger Scope from Maths channel]

Hi @doggy

The Analog Discovery oscilloscope inputs are differential. This means the read value is the difference between the positive and negative inputs. For channel 1 the positive input is labeled 1+ and the negative 1-, for channel 2: 2+ and 2-
The BNC adapter and connectors are single ended. This means the negative input is tied to ground.
Triggering is available on oscilloscope input channels, internal and external triggers, and for newer device also on hardware filters, AWG output...
Trigger on Math channel is not available since this is performed only in the software/application.
If you want to trigger on differential signal use differential input.

[Frequency-dependent sweep levels for network analyzer]

Hi @clb

You could use table or custom amplitude modes.

[Waveforms App and Libraries unsigned on Mac OS X]

Hi @fractalbrain

The application is signed. I just updated to Mac 14.3.1 and tested it.

[wrong device opened after selecting from device enumeration list, python analog discovery]

Hi @mikeyc

I tried the code and it works as expected, it opens the device specified by sn.
