Additional Function
Using the HP E1345A
Multiplexer
This is an example of how to setup scanning when using an HP E1345A
multiplexer configured as a switchbox and the HP E1326B multimeter used
with no multiplexers assigned to it. The two subprograms used in this
example are Scan_100µsec and Scan_10µsec. Configuration for this
example is as follows:
Connect two cables as:
Multimeter’s "Ext Trig" to "Trig Out" on the E1406 or E1300/E1301.
Multimeter’s "VM Compl" to "Trig In" on the E1406 or E1300/E1301.
The two different subprograms are used to demonstrate a more effective
method of scanning (Scan_100µs) and a less effective method of scanning
(Scan_10µs). Comments follow the program and subprograms providing
information about the instruments execution.
Scan_100µs demonstrates the multimeter set for an aperture of 100µs and
achieves a scan rate of 123/sec in the E1300 B-size mainframe. Whereas,
Scan_10µs demonstrates the multimeter set for an aperture of 10 µs and
achieves a decrease in scanning speed.
