Module Overview
MC3065 (DMM Module)：
The DMM module is used to measure the signals under test and has 6½ digit reading
resolution. The measurement functions include DCV, ACV, 2-wire resistance, 4-wire
resistance, frequency, period, temperature and any sensor.
Note: After connecting the DMM module, make sure that the signal under test
connected to the analog bus is no greater than 300 Vdc or 300 Vrms.
MC3120 (20-Channel Multiplexer):
All 20 channels switch both HI and LO inputs, thus providing fully isolated inputs to
the DMM module. MC3120 is divided into two banks (called A and B) of 10 two-wire
channels each. When making 4-wire resistance measurement, the instrument
automatically pairs channels of A bank and B bank. All channels are
break-before-make. You can close multiple channels on this module only if you have
not configured any channel to be part of the scan list. This module can be connected
with MC3065 (DMM Module, if MC3065 is currently inserted). For the specifications of
this module, please refer to the User’s Guide or Data Sheet of this product.
MC3132 (32-Channel Multiplexer)：
All 32 channels switch both HI and LO inputs, thus providing fully isolated inputs to
the DMM module. MC3132 is divided into two banks (called A and B) of 16 two-wire
channels each. When making 4-wire resistance measurement, the instrument
automatically pairs channels of A bank and B bank. All channels are
break-before-make. You can close multiple channels on this module only if you have
not configured any channel to be part of the scan list. This module can be connected
with MC3065 (DMM Module, if MC3065 is currently inserted). For the specifications of
this module, please refer to the User’s Guide or Data Sheet of this product.
MC3164 (64-Channel Single-Ended Multiplexer)：
All 64 channels can switch the HI input only. MC3164 is divided into two banks (A and
B) of 32 single-ended channels each. All channels are break-before-make. In any
case, you cannot close multiple channels on this module. This module can be
connected with MC3065 (DMM Module, if MC3065 is currently inserted) but cannot
be used for 4-wire resistance measurement. For the specifications of this module,
please refer to the User’s Guide or Data Sheet of this product.
MC3232 (32-Channel Reed Multiplexer)：
The MC3232 is applicable to high-speed scan and high-throughput auto test
applications. All 32 channels can switch both HI and LO inputs, thus providing fully
