This exercise allows you to close multiplexer channels and make voltage
measurements using a scanning voltmeter configuration. To do this
exercise, you will need the following items. See Figure 1-20 for equipment
configuration.
•
E1411B multimeter
•
E1476A multiplexer
•
2.5 inch Analog Bus cable (E1400-61605)
•
Zero Ohm jumpers (such as paper clips)
•
Resistors (any value)

Figure 1-20. Exercise 5: Equipment Configuration
Since the E1411B multimeter and E1476A multiplexer form a scanning
voltmeter configuration, the E1476A must have a logical address that is
sequential to the E1411B. Also, the E1411B must be at an instrument
address (logical address divisible by 8). Set the E1411B to logical address
24 (secondary address is 24/8 = 03) and the E1476A to logical address 25.
The modules must be installed in adjacent slots with the multiplexer to the
right of the multimeter. The scanning voltmeter is addressed from GPIB
interface 7 (or the interface you use instead of 7), primary address 09 and
secondary address 03. The scanning voltmeter address is 70903 and the
multimeter controls the multiplexer module.
As required, set the E1411B multimeter to logical address 24 and the
E1476A multiplexer to logical address 25. Next, install the instruments in
the mainframe and connect the Analog Bus cable between the E1411B
multimeter and the E1476A multiplexer. Then, connect resistors and/or
Zero Ohm jumpers to desired channels (between 0 and 31) on the terminal
module.
