Well ....

I have just bought a NIST DSS5 unit on the 'Bay , # 190818033819

It's supposed to be a 0..7v AC reference standard , but i have no info
about the unit or more important the GPIB command set.

I don't expect NIST to keep the commandset (manuals) a secret , but
doesn't have any contacts at NIST.

I would really appreciate if anyone on the list could help me , in getting
a NIST contact. Otherwise i suppose i have bought an expensive (EU
shipping) box of components.

I have found a bit of info here http://tiny.cc/tvzzvw

As far as I remember the box is just a simple D/A converter creating a
stepped approximation of sine wave. The DC level of each step is
syncronously (GPIB) measured by a 3458A and the rms value is
calculated from that data by a special software. The system relies on
the speed and DC accurary of the 3458A, the source itself is not
accurate or stable.

Hmm ...
That would be a dissapointment.
I don't have a 3458A
