Hi,
there exist three manuals,
5335-90005 - Serial #2024A and below, 1980, preliminary pdf manual on
agilent.com
5335-90021 - Serial #2224A and below, 1983, pdf from Artekmedia, very
good scan for $7.50
5335-90044 - Serial #3154A and below, 1994, very good reprint from
manualsplus for about 70$
If you don't have the latest device, Artek Media document is absolutely
sufficient for description of Opt. 040, i.e. HPIB instruction set and
schematics. (SW is different, also input amplifier / front end A12
and amplifier support A11)
Btw.: I've got a nice 5335A with ser no 2820, Opt. 10, 30 , 40 (10811
oven, 1,3Ghz C-input - latest divide-by-64 version, and full front end
remote steering).
I've found out, that it definitely resolves 1ns in Time and Freq.
measurements, in contrast to 2ns as stated by all the latest specs. in
the manuals and all the HP catalogues.
Gordon, and other 5335 owners - would you please check your instruments
on that, to find out if firmware has changed later on, or simply if the
specification is wrong?
I get 11 significant digits over the bus and on the display, if I
measure for >100s.
I'd expect 12 digits for >1000s at least over the bus, as 14 digits are
reserved for the mantissa (incl. sign and decimal point) but nothing
happens.
Anybody got an idea, how to get more digits, perhaps with undocumented
commands?
This counter potentially delivers nearly unlimited resolution, as the
overflow is counted in many additional bytes, which I would like to read
out.
Thanks - Frank
