That's a binary block header that says:
  4 Characters in the "number of bytes" number
 1608 bytes to followÂ
Then all your data. The data is binary, so you'd have to have the manual to decode what it means - or take a few good guesses on array types.

I am working with a 8713B analyzer and I can't figure out how to decode the trace data. I don't have a programming manual for it, so I learned how to talk to it by using the panel driver and spying with the gpib monitor.
Â
So, to read the trace:
FORM REAL,64 <CR><LF>
TRAC CH1FDATA <CR><LF>
Â
Then a a ton of data comes back. How do I decode it? There's a header of some sort?
Â
Thanks,
Bill

whats does tha data look like? how about posting the first 50 characters
or so?
Odds are it is a BINBLOCK so you'd read it in BINBLOCK format

Yep -it is indeed a BINBLOCK
the #41608 is the header and it specifices that there are 1608
characters following.
Set up a BINBLOCK transaction ( READ BINBLOCK x REAL 64 ARRAY:* )
with 64 bit real format. You'll have
201 data points popping out.
