vrf dual processing?

Question asked by jay.johannes on Nov 7, 2005
Hi Dean,

HP never created drivers for these instruments (I was the manager of the
group that wrote them).  However, many people had success using the 8653B
driver with the A instrument.  It was simply a matter of not hitting a
couple of buttons for functions that didn't exist in the a model (or was it
that the freq and power ranges were different?  Been too long).

The 436 was a little trickier.  However there is an unsupported panel driver
(who cares, all panel drivers are unsupported these days) down in section 5
of the panel driver link page.  This driver was written by a very
knowledgeable field engineer and worked well.  The unsupported tag was more
a matter of politics at the time than a reflection on the quality of the
driver.

The following page lists the panel drivers for VEE:

Can anyone out in VRF-land help me find drivers and/or VEE programs for
a couple of OLDER H-P instruments?? I have not had any success finding
usable drivers for them from either Agilent's or National's web sites.
Maybe, there is, out there somewhere, a VEE program or panel-driver for
these two pieces. The instruments are 1) H-P 436A power meter  and 2)
H-P 8673A signal generator. Any input will be very much appreciated!

Thanks!

Good advice. Anyone doing lots of simulations ( or "number crunching" )
should have a dual ( or better) CPU machine. This allows full usage for
number crunching without impacting other ongoing use of the machine.

>   What will Vee do with them?

Nothing directly since VEE is a single thread.

No

No. But you certainly can run multiple VEE processes and the OS will
assign those to processors as needed.

>  Can anyone give me advice?

Sure. If you really need to do serious number crunching write
yourself an SMP routine in C or whatever. Then call that from VEE as
needed. That gives you the best of both worlds.
