other instruments when making measurements.
Synchronizing
Instruments
The following example shows how you synchronize instruments. In this
example, the Microwave Switch switches a signal to be measured by a
counter. This program verifies that the switching is complete before the
counter begins a measurement. For the example, use:
•
an HP-IB select code of 7, primary address of 09, and secondary
address of 06 for the Counter
•
an HP-IB select code of 7, primary address of 09, and secondary
address of 15 for the Microwave Switch
•
an HP Series 200/300 Computer with HP BASIC
Execute:
10
!Close channel 101 and request confirmation that the channel is
15
!closed.
20
OUTPUT 70915;"CLOSE (@101);*OPC?"
30
!Read confirmation.
35
OUTPUT 70915;"CLOSE? (@101)"
40
ENTER 70915;A

!At this point (channel is closed) the measurement can be made.
