SKU CH-X6N9-90YFE

Handheld 3-in-1 oscilloscope, multimeter and waveform generator with 40 MHz bandwidth, 250 MS/s sampling and 3.5 inch colour LCD

  • TypeTest Instrument & Gauge Parts
  • 40 MHz bandwidth captures fast signals
  • 250 MS/s sample rate resolves detail
  • 5 inch colour LCD reads outdoors
  • 20 000 count multimeter measures precisely
  • Built-in waveform generator adds stimulus

Handheld 3-in-1 Test Tool

The WUQ HDS242S combines a dual-channel oscilloscope, a multimeter and a waveform generator in one portable unit. A 3.5 inch colour LCD presents clear readings in dim or outdoor light. The instrument is designed for field work and fits comfortably in one hand.

Automotive diagnostics and education

Technicians troubleshooting injectors, ignition coils or sensor signals on vehicles will find the 40 MHz bandwidth and 250 MS/s sample rate useful. Students running experimental circuits also benefit from the integrated functions. Buyers who need more than two oscilloscope channels or higher bandwidth should consider other instruments.

40 MHz bandwidth dual-channel scope

The oscilloscope section provides 40 MHz bandwidth with a 250 MS/s sample rate and 8 K record length. Vertical sensitivity ranges from 10 mV/div to 10 V/div with DC, AC and ground coupling. The built-in multimeter offers a 20 000 count display.

Questions about this item

What comes in the box with the WUQ HDS242S and do I need to buy probes or leads separately?

The HDS242S is a 3‑in‑1 instrument combining a dual‑channel oscilloscope, a 20000‑count multimeter and a waveform generator in one handheld unit, so no extra modules are required for those functions.

Which version of the HDS242S should I choose for automotive sensor work?

The single model listed delivers 40 MHz bandwidth, 250 MS/s sample rate and 10 mV/div sensitivity, covering injector and ignition‑coil diagnostics without needing a higher‑spec variant.

How does the 40 MHz bandwidth perform when capturing fast ignition signals on a real vehicle?

With 250 MS/s sampling and an 8‑bit vertical resolution the scope resolves rise times well within the 40 MHz limit, while the 10000 wfrms/s refresh keeps the display responsive during live testing.
