The Plug-In Modules at a Glance
For complete specifications on each plug-in module, refer to the module
sections in chapter 9.
34901A 20-Channel Armature Multiplexer
20 channels of 300 V switching
Two channels for DC or AC current measurements (100 nA to 1A)
Built-in thermocouple reference junction
Switching speed of up to 60 channels per second
Connects to the internal multimeter
For detailed information and a module diagram, see page 164.
Each of the 20 channels switches both
HI and LO inputs, thus providing
fully isolated inputs to the internal multimeter. The module is divided
into two banks of 10 two-wire channels each. When making four-wire
resistance measurements, channels from Bank A are automatically
paired with channels from Bank B. Two additional fused channels are
included on the module (22 channels total) for making calibrated
DC or
AC current measurements with the internal multimeter (external shunt
resistors are not required). You can close multiple channels on this
module only if you have not configured any channels to be part of the
scan list. Otherwise, all channels on the module are break-before-make.
34902A 16-Channel Reed Multiplexer
16 channels of 300 V switching
Built-in thermocouple reference junction
Switching speed of up to 250 channels per second
Connects to the internal multimeter
For detailed information and a module diagram, see page 166.
Use this module for high-speed scanning and high-throughput
automated test applications. Each of the 16 channels switches both
HI and LO inputs, thus providing fully isolated inputs to the internal
multimeter. The module is divided into two banks of eight two-wire
channels each. When making four-wire resistance measurements,
channels from Bank A are automatically paired with channels from
Bank B. You can close multiple channels on this module only if you have
not configured any channels to be part of the scan list. Otherwise, all
channels on the module are break-before-make.
