Comments If you have an HP 75000 Series B mainframe with a front panel keyboard, errors can be monitored by selecting “ Monitor” from the Switch menu. If errors occur when the program executes, the “ err” annunciator will appear. Entering SYST:ERR? repeatedly from the keyboard reads all of the messages in the error queue.

Synchronizing the Microwave Switch

Synchronizing Instruments

This section discusses synchronizing the Microwave Switch module to other instruments when making measurements.

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.

20OUTPUT 70915;"CLOSE (@101);*OPC?"

30!Read confirmation.

35OUTPUT 70915;"CLOSE? (@101)"

40ENTER 70915;A

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

60OUTPUT 70906: “MEAS1:FREQ?”

70ENTER 70906:Meas_value
