It's not documented, AFAIK. Mine seemed to hang pretty regularly if I 
tried to do a GPIB interface clear/device clear while it was in talk 
mode and in the middle of a measurement.

That seems to have gotten better with the newer firmware, but I noticed 
one new bug - I used to be able to do an "ST8ST1" to set the reference 
and immediately go back to "mean." With the newer firmware, it seems I 
have to pause between the two, or the reference isn't set correctly.

The firmware Mark so kindly provided is from a unit with date code 
2332A (32nd week of 1983), which is a fairly early revision of the 
5370B (1st rev was 2316A, 16th week of 1983). 5370B revisions went to 
at least 2904A (4th week of 1989). There may be even newer firmware 
which has more bug fixes.

I put cksum and md5sum for this image on the web page, if someone with 
a newer 5370B wants to compare with what they have.
