YOKOGAWA DLM3054HD Mixed Signal Oscilloscope

YOKOGAWA DLM3054HD Mixed Signal Oscilloscope

Instrument positioning and core use

DLM3054HD is a 4+16 channel mixed signal oscilloscope (4 analog channels+16 digital channels), with the core advantages of high sampling rate, large storage depth, and multi-channel synchronous measurement capability. It can simultaneously capture analog signals (such as voltage and current) and digital signals (such as SPI, CAN, UART communication signals), realizing the linkage analysis of "analog waveform+digital logic".

The main application scenarios include:

Automotive electronics: ECU (Electronic Control Unit) signal monitoring, CAN/LIN bus communication analysis, motor drive waveform and control logic synchronization diagnosis.

Industrial control: timing matching of PLC (Programmable Logic Controller) output signals and sensor feedback signals, analysis of servo system voltage/current and pulse signals.

Power electronics: synchronous capture of inverter switch waveforms, IGBT drive signals, and protection logic to locate switch losses or fault triggering causes.

2. Hardware structure and component functions

(1) Core components of the front panel

Component name, location, and function

Four BNC interfaces (CH1~CH4) on the left side of the analog channel input terminal, connected to analog probes (such as Yokogawa 701977 differential probe), supporting 1X/10X/100X attenuation ratio settings

The "DIGITAL" port on the right side of the digital channel interface is connected to 16 logic probes (which need to be purchased separately, such as Yokogawa 701982) to achieve digital signal acquisition

The central area of the touch screen supports multi finger zoom (waveform zoom), drag and drop (waveform translation), and displays function soft keys (F1~F6) at the bottom

The front panel buttons include "Auto Setup", "Run/Stop", "Single", "Save", and channel on/off keys (CH1-CH4, DIGITAL)

Knob and directional keys vertical/horizontal position knob (adjust waveform up/down/left/right offset), vertical/horizontal zoom knob (adjust sensitivity/time base), directional keys (menu navigation)

There are two USB 3.0 ports at the bottom of the USB host interface, which can be inserted into a USB flash drive/portable hard drive to save data, or connected to a mouse/keyboard to improve operational efficiency

(2) Core components of the rear panel

Component Name Function

AC power interface connected to dedicated power cord (input 100~240VAC, 50/60Hz, maximum power consumption 120VA)

Ethernet interface RJ45 interface, supporting TCP/IP protocol, used for PC remote control (VISA/LXI compatible) or data network transmission

Connect the HDMI output interface to the monitor and synchronize the content of the oscilloscope screen (supporting 1080P resolution)

EXT TRIG interface BNC interface, receiving external trigger signals (trigger sensitivity ≤ 50mV, frequency ≤ 100MHz)

AUX OUT interface BNC interface, output trigger signal or sampling clock (for synchronizing other instruments)

USB device interface USB Type-B interface, connected to PC, enables high-speed data transfer (such as waveform file export) or remote control
