Logic analyzer

[Rhayes]

I have an old Gould Biomation Logic analyzer K100-D, it has a GPIB interface. I picked up a GPIB card to see what I can do with it but I'm a little stuck, does anyone have any idea what commands can be sent to this device, there is a mention of a supplemental manual for the GPIB but that is the one manual I don't have. A search of google turned up nothing.
I have tried some of the stardard commands for 488.2 but they didn't work, I'm assuming that since the K100-D uses 488-1975 that the commands might be different.

Thanks

Hi Ron,

I'm sorry to say that I am not familiar with this instrument, but if it is older than 10 years it probably does not respond to 488.2 commands. Can you contact the manufacturer for this information? Hopefully someone else will be of more help to you.

Good luck,

JenK

Manufacturer is no longer in business. I was under the impression though that 488.2 was a subset of 488-1975 and just added commands to the existing ones.

Oh well it wsa worth a shot!

488.2 is a superset of previous gpib versions. It did add a set of standard commands (i.e. *TST, *RST, *IDN?) for doing certain operations. Even with 488.2, the command language for performing instrument operations such as setting up a test or taking a measurment was not standardized. That sort of happened with the adoption of SCPI but even that does not guarantee that you can program an instrument without having a manual. There are places that have archives of instrument manuals. I don't have any of their web addresses (try googling obsolete instrument manuals) and the ones I once found did charge a fee but it might be your only hope.

I actually managed to find a manual for this device. it does show the commands in it but I'm a little confused how to put them together.

It says that ther is one type of command called keystroke records (ASCII "K")  and one of the keystroke functions is "&0". It does show you the format; record type,keystroke data,record terminator (CR/LF)

I have to assume that the CRLF is placed automatically in MAX's communicate with device window. I tried to just write "K&0" but no luck. can anyone shed some light on this for me?

The manual is 9meg so it's a little big to upload.

Thanks

CRLF isn't placed automatically in the "Communicate with instruments" window in MAX because not all instruments require that.  Though I don't believe this is documented, you can use "\r" and "\n" for carriage return and linefeed respectively in MAX.
