C.3 USING MULTIPLE HP 3421A INSTRUMENTS
If more than one HP 3421A is in the system, a custom program may use the keywords to control the
second instrument as long as the instrument buffer is restored to the original instrument. This can be done
by preserving the location of the currently active instrument, assigning the second instrument to take the
measurements, and re-assigning the original instrument.
The following example, suitable for use by either = TF IF or MIMI TIE, preserves the current HP 3421A
assignment and measures DC Volts on channel § of the second HP 3421A on the loop:
SUE CLESTORO A
H¥=HOREZ4Z1F
sE=z421
sHRFZ421 020
