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

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

a matter of politics at the time than a reflection on the quality of the

The following page lists the panel drivers for VEE:
