Rigol MC3648 MATRIX Module

The Rigol MC3648 MATRIX Module is a 4×8 two-wire matrix switch module engineered for flexible signal routing and switching within the Rigol M300 DAQ System Mainframe. It delivers 32 two-wire crosspoints capable of simultaneous input/output connections, supporting data acquisition, signal processing, and multi-point device testing. The module's architecture permits expansion through cascading - multiple matrix switches can be connected to form larger configurations (8×8, 4×16) up to a maximum of 160 total crosspoints.

With a bandwidth of 1 MHz and channel isolation rated at 300 VRMS, the MC3648 accommodates signals up to 300 VRMS and 1 A RMS, dissipating up to 50 VA. Open/close switching occurs at 200 channels/s, enabling rapid reconfiguration between measurement points.

Compatibility & Integration The MC3648 integrates directly into the Rigol M300 DAQ System Mainframe via golden edge connector interface. Signal connections use the M3TB48 terminal block. The host M300 mainframe provides RS232, USB, LAN (LXI-C), and GPIB control interfaces for remote operation and system integration.
