In summary, the Rigol MHO934 is a 4-channel mixed-signal digital oscilloscope built around a 12-bit ADC, 350 MHz of analog bandwidth, and a 4 GSa/s real-time sample rate. With 100 Mpts of standard memory (expandable to 500 Mpts), a 1,000,000 wfms/s fast-record capture rate, and a 7-inch capacitive multi-touch interface, it targets embedded design, power-electronics debug, education, and general-purpose bench work.
The MHO934 is used for time-domain analysis of analog and mixed-signal electronics — debugging microcontroller buses, characterizing switching-supply ripple, validating sensor outputs, and analyzing serial protocols such as I2C, SPI, UART, CAN, and LIN. The 12-bit vertical path resolves details that 8-bit instruments cannot, which is particularly valuable for power-rail ripple measurements and small-signal work riding on larger DC offsets.
Embedded developers, hardware engineers, educators, and lab technicians who need a 4-channel scope with protocol decode, deep memory, and a usable touch UI at an accessible price point. The optional 2-channel AFG and Bode plot turn the MHO934 into a self-contained loop-response and stimulus-response bench in a single chassis.
The MHO934 provides 350 MHz of analog bandwidth (50 Ω path) with a typical 10%–90% rising time of 1 ns and an effective number of bits (ENOB) of 8.5 at 10 MHz, 100 mV/div. Trigger holdoff spans 8 ns to 10 s, and the trigger sensitivity is 0.5 div (≥50 mV/div). Time-base accuracy is ±1.5 ppm ±1 ppm/year. Standard memory is 100 Mpts single-channel; the MHO900-RLU-05 option extends this 5× to 500 Mpts.
The MHO934 conforms to EMC DIRECTIVE 2014/30/EU and IEC 61326-1:2013 Group 1 Class A, with safety to EN 61010-1:2019, IEC 61010-1:2016, UL 61010-1:2012 R7, and CAN/CSA-22.2 No. 61010-1-12:2017. It supports IEEE 488.2-compliant SCPI for programmatic control over LAN (LXI-C), USB, and supports a Web Control interface for browser-based remote operation.
