Craig,
Just a thought about your HPIB question... you have to be careful to
put the correct syntax for the command. In your example, it looks to
me like a space is missing, i.e. it should look like "FREQ:START ",A.
Usually with SCPI commands you need to separate the actual value from
the rest of the command with a space. To do that, the space must be
within the quotes.
Good luck,
Lois

Sir:
Well, no. Try putting commands through a TO STRING and inspecting them on
an ALPHANUMERIC to get an idea of exactly what you're sending to the
instrument.
