Rigol MC3164 MUX64 Module. 64-channel Single-ended Multiplexer

64 channel multiplexer module for use with M300 DAQ System Mainframe and MC3065 DMM module. The M3TB64 is the mating terminal block for this module.

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.

Measurement Connections Using External Terminal Blocks

M300 provides 6 kinds of terminal blocks to easily connect the signal to be measured to the module. The models of the terminal blocks and corresponding modules are listed in the table below. This section introduces how to use the external block.

Note: for the MC3724, the signal can be connected to the SMB connectors on the module directly. No terminal block is needed.

WARNING: Cut off all the power supplies before opening the terminal block or removing the terminal block from the module. 

1. Place the terminal block with the front (with the RIGOL caption) facing downward and pull the two latches in the arrow direction in the figure below and press them down. Place the terminal block with the front facing upward and pull the upper cover of the terminal block upward and remove it.

2. Connect the cables for connecting the signal under test according to the labels on the circuit board of the terminal block (for the connecting method, refer to Table 1-1). Pass the binding wires through the two groups of holes as pointed out by the arrows in the figure below to fix the cable connected. Pay attention to the channel or terminal connected to the cable to ensure that the signal connected is correct.

3. Connect the terminal block to the module via interface 1 (the interface definition is in Figure 1-7) on the module and screw down the two screw rods onto the nuts on the module.

4. Close the upper cover of the terminal block.

5. Insert the module with the terminal block into the slot of the mainframe.
