Example: Scanning with External Device

This example uses the HP E1300A/E1301A mainframe "Trig Out" port to synchronize the RF multiplexer channel closures to an external measurement device. See the figure below for typical user connections. For measurement synchronization, the HP E1300A/E1301A Trig Out BNC port is connected to the instrument External Trigger In port.

For this example, the HP E1300A/E1301A and the instrument are connected via HP-IB with HP E1300A/E1301A address of 709 and instrument address of 722. The RF multiplexer logical address is 120 (secondary address =120/8 =15). The measurements are transferred directly to the computer. (Appropriate instrument commands must be added to line 10.) The sequence of operation is:

1.INIT (line 50) closes channel 100.

2.The channel closure causes a trigger output from the "Trig Out" port.

3.Trigger to Ext Trig In initiates channel 100 measurement.

4.Result is sent to the computer (lines 60 to 80).

5.TRIGGER command (line 90) advances the scan to channel 101.

6.Steps 2-5 are repeated for channels 101 through 102.
