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_100
µ
sec and Scan_10
µ
sec. 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_100
µ
s) and a less effective method of scanning
(Scan_10
µ
s). Comments follow the program and subprograms providing
information about the instruments execution.
Scan_100
µ
s demonstrates the multimeter set for an aperture of 100
µ
s and
achieves a scan rate of 123/sec in the E1300 B-size mainframe. Whereas,
Scan_10
µ
s demonstrates the multimeter set for an aperture of 10
µ
s and
achieves a decrease in scanning speed.
