RIGOL Mixed-interface Separator Line The mixed-interface separator line is used to convert the [RS-232/Alarms/Ext Trig] interface (25-pin male) at the rear panel to two 9-pin interfaces. Wherein, one is a 9-pin male interface used as a standard RS232 interface and the other is a 9-pin female interface used for alarm output and external trigger signal input.
RIGOL Fuse The AC, 250V, T250mA fuse is the alternate power supply fuse for the DMM module; the AC, 250V, T3.15A fuse is the alternate power supply fuse, as shown in the figure below. The AC power supply connected via the power socket is divided into two paths with one path providing power for the DMM module and the other path providing power for the other circuits. M300 provides the power supply fuse and independent power supply fuse of the DMM module.
RIGOL M300 Optional Accessories Modules and Terminal Blocks Module Appearance Diagrams M300 provides 8 kinds of modules, including the DMM module, 20-channel multiplexer, 32-channel multiplexer, 64-channel single-ended multiplexer, multi-function module and etc. The appearance diagrams of the modules are as shown in the figures below.
RIGOL To Connect the Module and Terminal Block Multiple signals to be measured can be connected to the plug-in modules through the external terminal blocks and then switched to the DMM module or external DMM. 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 side (with the RIGOL caption) facing downward; pull the two latches in the arrow direction in the figure below and press them down.
RIGOL Figure 4 Connect the Terminal Block and Module 4. Close the upper cover of the terminal block. Figure 5 Close the Upper Cover of the Terminal Block 5. Insert the module connected with the terminal block into the slot of the mainframe. As shown in Figure 1, there is a golden circuit board edge both on the top and bottom of the module. Aim the two edges with the sliding chutes in the main frame slot and push the module in until you hear a sound.
RIGOL Connecting Cable Specification Requirements To reduce the error caused by the connecting cables, 16AWG to 28AWG conducting wires with 5mm to 6mm stripping length are required. You are recommended to use 20AWG conducting wire with 5.5mm stripping length. The diameter, area and copper impedance of each kind of conducting wire are as shown in the table below. Note: The "Copper Impedance" in the table below refers to the DC impedance of the single-direction copper wire under 25℃.
RIGOL DMM Module The DMM module (MC3065) is used to measure the signals under test and has 6½ digit reading resolution. The measurement functions include DCV, ACV, DCI, ACI, 2-wire resistance, 4-wire resistance, frequency, period, temperature and any sensor. After connecting the DMM module, make sure that the signal under test connected to the analog bus is no greater than 300Vdc or 300Vrms. The DMM module is as shown in the figure below.
RIGOL Multiplexer and Terminal Block M300 provides 4 kinds of multiplexer modules as well as 4 kinds of external terminal blocks for the multiplexer modules to connect the signals under test in 1-wire, 2-wire and 4-wire connection modes.

RIGOL 2. MC3132 and M3TB32 MC3132 is a 32-channel multiplexer. All the 32 channels switch both HI and LO inputs, thus providing fully isolated signals for the DMM module. MC3132 is divided into two banks (called A and B) with 16 two-wire channels for each bank. When making 4-wire resistance measurement, the instrument automatically pairs the channels of A bank and B bank. All the channels added into the scan list are break-before-make.

RIGOL 3. MC3164 and M3TB64 MC3164 is a 64-channel single-ended multiplexer. All the 64 channels can switch the HI input only. MC3164 is divided into two banks (A and B) with 32 single-ended channels for each bank. All the channels added into the scan list are break-before-make. In any case, you cannot close multiple channels on this module. MC3164 can be connected with MC3065 (the DMM module, if MC3065 is currently inserted). MC3164 cannot be used for 4-wire resistance measurement.

RIGOL 4. MC3324 and M3TB24 MC3324 is a 20-voltage-channel + 4-current-channel mixed multiplexer. All the 20 voltage channels switch both HI and LO inputs, thus providing fully isolated inputs for the DMM module and the 20 voltage channels are divided into two banks (called A and B) with 10 two-wire channels for each bank. When making 4-wire resistance measurement, the instrument automatically pairs the channels of A bank and B bank. All the channels added into the scan list are break-before-make.

RIGOL To Connect the Signal under Test For different multiplexer and external terminal block, the connection mode of the signal under test is different. 1. 1-wire Mode MC3164 provides 64 single-ended channels and a commom LO terminal. The signal under test is connected in 1-wire mode, as shown in the figure below. LO HI Figure 20 1-wire Connection Mode 2. 2-wire Mode When MC3120, MC3132 or MC3324 is used, the signal under test can be connected in 2-wire mode, as shown in the figure below.
RIGOL 3. 4-wire Mode When MC3120, MC3132 or MC3324 (the first 20 channels) is used, the signal under test can be connected in 4-wire mode, as shown in the figure below. When 4-wire mode is used for connection, for MC3120 and MC3324 (the first 20 channels), the instrument pairs channel n with channel n+10 (wherein, n is an integer between 1 and 10); for MC3132, the instrument pairs channel m with channel m+16 (wherein, m is an integer between 1 and 16).
RIGOL Measurement Notices When using the mutliplexer module for measurement, make sure that both the amplitude of the signal under test and the commom mode voltage are no greater than the maximum input voltage of the module. When the multiplexer module is used to measure an object with high-power output ability (such as battery and power supply), to avoid damaging the relay, you are recommended to connect a fuse in series when making connections (as shown in the figure below).
RIGOL Actuator and Terminal Block MC3416 is a 16-channel actuator. It can connect signals to the device under test or enable external devices. Any of the 16 channels can switch to Normally-Open (NO) and Normally-Closed (NC) states. MC3416 is as shown in the figure below. Figure 23 MC3416 M3TB16 is an external terminal block applicable to MC3416. Its appearance and detailed layout are as shown in the figure below.

RIGOL Matrix Switch and Terminal Block MC3648 is a 4×8 two-wire matrix switch. The 32 two-wire crossing points can connect any combination of inputs and outputs at the same time. MC3648 is used to connect multiple devices to multiple points on the device under test at the same time when making tests. You can connect the rows and columns of multiple matrix switches to form a relatively larger matrix (such as 8×8 and 4×16, the number of crossing points cannot exceed 160).

RIGOL To Connect Multiple Matrix Switches You can connect the rows and columns of multiple matrix switches to form a relatively larger matrix (such as 8×8 and 4×16; the number of crossing points cannot exceed 160, namely connecting 5 MC3648 modules). This section introduces the operation methods by introducing how to connect two MC3648 modules.
RIGOL Connect the rows of the two M3TB48 modules to increase the number of columns and form a 4×16 matrix. Notices 32 When using the matrix switch, you can close multiple channels and connect multiple inputs to multiple outputs at the same time. Before making any connection, make sure that the connection will not cause any danger. The combined matrix provides more complicated signal switch. You can connect more inputs to more outputs at the same time.
