Yes, that is what I did, but your list is a lot cleaner than I recovered. What did you use to scan the binary? Is your list the raw output from the scan, or have you done some manual cleanup?

It still nags me that it simply ignores set/save and code: commands. Considering that there is no apparent recognition of those strings (i.e. not in the command list), yet they are ignored so quietly while the slightest error in any other command can provoke anything from a warning message to a 'hang'. It makes me wonder if they never actually reach the module... which raises the question of who would be filtering them?

All very low on the list of priorities, I know, but that's just how I'm wired :palm:

I just used a simple strings utility on the firmware binary.  I was using a Windows PC at the time and this is the one I happened to use (which originally came from www.sysinternals.com).

As far as I could see all of the command string text was located in one contiguous table. I just manually selected and copied that text.

After seeing some of the other text in the firmware I'm curious what you can do if you attach a serial connection to the analyzer module CPU board. Maybe you can't do anything useful other than learn more about how the analyzer module firmware works. I haven't tried to do any disassembly of the firmware myself yet.

I have a TLA614 which I have been using for past 10 years. Last month it started failing the power on diagnostics with the NVRAM check fail. Have gone through the other replies. The question is If I replace the NVRAM  IC DS1225AD-85, will the error be eleminated after self-calibration? How to backup the contents of the NVRAM?

For posterity, this works on the 5000 series also.

Although this is an old topic, I've also succeeded to update a TLA 7AA4 module.
I came across this on the Tek website:

https://www.tek.com/en/support/software/utility/visacmd-command-line-utility

It also allows scripting.
 
J:\IDA\TLA\visacmd>visacmd /a=TCPIP::192.168.178.194::vxi0,2::INSTR /c=*IDN?
TCPIP::192.168.178.194::vxi0,2::INSTR <- *IDN?
TCPIP::192.168.178.194::vxi0,2::INSTR -> TEKTRONIX,TLA7AA4,B013745,SCPI:94.0 FVER:<VERSION>


J:\IDA\TLA\visacmd>visacmd /a=TCPIP::192.168.178.194::vxi0,2::INSTR /c=SYST:CONF:MAX:SPEED?
TCPIP::192.168.178.194::vxi0,2::INSTR <- SYST:CONF:MAX:SPEED?
TCPIP::192.168.178.194::vxi0,2::INSTR -> 450


J:\IDA\TLA\visacmd>visacmd /a=TCPIP::192.168.178.194::vxi0,2::INSTR /c=SYST:CONF:MAX:DEPTH?
TCPIP::192.168.178.194::vxi0,2::INSTR <- SYST:CONF:MAX:DEPTH?
TCPIP::192.168.178.194::vxi0,2::INSTR -> 33554432

J:\IDA\TLA\visacmd>notepad update.bat
SYST:PASS:INST:PASS "PitBull<VERSION>"
Set Parameters
Code:
SYST:CONF:DEPTH 33554432
SYST:CONF:SPEED 450
Save Parameters:
Code:
SYST:PASS:INST:UPD 1652097781

J:\IDA\TLA\visacmd>visacmd /a=TCPIP::192.168.178.194::vxi0,2::INSTR /c=update.bat /l

This because for some reason The OpenChoice Talker Listener didn't go well for me.

Needless to say change the <VERSION> with what comes out of the *IDN? command.
