In Sensor's loop function only static transfer calls can be used, see:

This is the most operative tech support from the manufacturer I've had in my 7 years of active engineering life. Kudos!

For long transfers maximum is about 10MHz:
Rate is for the loop function:

It is not possible, each of the 16 DIO channels has its own 32ki buffer.

Hi @jostikas
Thank you for the observation. 
The crash occurs if the Find / Case Sensitive option was previously checked.
It is fixed for the next version.
WaveForms - Safe Mode starts the application without loading the static configuration.

Hi @Ola
In each loop iteration you want to transfer 32 times 24 bits with a clock rate of 6.25MHz. This can be done with a loop rate of at most 7.8kHz = 6.25MHz / 32 / (24+1?) ? because it depends on the specified delays.
The 5th AD3 configuration allocates 32ki logic and pattern buffer. For each bit it needs 2 or 4 samples, 32768/2/25, so N can be up to about 650.
When transferring more bits than the Logic Analyzer device buffer, the data need to be streamed over USB, with AD3 the max rate is about 10Msps.

After double checking my digital_out on a scope, I see it is running at 25 MHz, not 2 MHz.  So my 4 samples per period is sampling at 100 MHz.  This issue is closed due to my error.  Thanks for the help.

Hi @Ola
The Write/CmdWrite only writes to D0, like:
CmdWrite(8, 0x10, 0, 16, [0x0001]); // write 0x0001 to register 0x10
and for Read0
CmdRead0(8, 0x10, 0, 16, 1); // read one 16bit word from register 0x10
The read/write functions activate CS during the transfer with hardware timing.
You can also use the Start/Stop functions for software CS control but this will take more time (like +1 millisecond) and this is also reflected in CS edge to bit transfer timing.

Hi @Ola
Set Initial DQ0 to Z

Thank you for the obsrevation.

Many Thanks Attila!

Hi @Mohamed Kamal
See:

 
If you are referring to the open/short compensation see WF SDK/ samples/ py/ AnalogImpedance_Compensation.py example and the following:
 

Hi @fizzbang
The Analog Discovery 1,2,3 oscilloscope inputs are suitable for such measurements since these are differential.
To measure the entire filter: channel 2 measured relative to 1.

To measure just the second part influence: channel 2 measured relative to 1.
In this case channel 1 absolute measurement will represent the first part only if the load does not cause W1 to drop.

Hi @bfpa40
Thank you for the information.

@attila thanks.  That did the trick.  I figured it might be something simple.

I updated to version 3.21.3 and everything works wonderfully now. 
Thank you once again for all your effort, it is greatly appreciated ! 

That sounds reasonable.  I was playing with many different items still learning how best to use the DD.  Thanks @attila.

Hi @gabagool @ZdenoQC
 

Hi @m72
 
 

Hi, I gave it a try. I encountered a 'unable to locate package LibQt5SerialPort' warning. After installing the package, I could successfully open the Waveforms application. Thank you for your assistance.

Hi @mms14
What operating system are you using ?
The 64bit WaveForms support Logic Analyzer captures of up to 256Mi samples and for 32bit it is limited to 10M.

Hi @Norm-12
The Spectrum analysis options can be enabled in Network Analyzer under Magnitude group.

@attila
I moved the script to the script tab from the SPI custom.  It works now.  The SPI example in the scrip also helped. 
Thank you. 
 
 

Hi @ZdenoQC @gabagool
The Protocol/Spy for AD2,3 will be fixed in the next version.
Thank you for the observation.
 

Hi @infield
Unfortunately only the DIOs can be controlled from Patterns and used by ROM logic.

Okay, thank you!
