WUQ

WUQ FNIRSI-2C23T 3-in-1 oscilloscope multimeter signal generator measurement tool

SKU CH-S5EA-RENB1

Combines a 2-channel 10 MHz oscilloscope, 10000-count multimeter and 2 MHz signal generator in one handheld tool

  • TypeTest Equipment
  • 3-in-1 oscilloscope, multimeter and signal generator in one handheld tool
  • Two-channel oscilloscope with 10 MHz bandwidth and 50 MSa/s real-time sampling
  • 10000-count multimeter measuring up to 750 V AC, 999.9 V DC and 9.999 A current
  • DDS signal generator producing seven waveforms up to 2 MHz with 1 Hz resolution
  • 3000 mAh rechargeable battery giving six hours standby on a 2.8-inch 320×240 display

Multi-Function Test Tool

The WUQ FNIRSI-2C23T integrates a two-channel oscilloscope, a digital multimeter and a DDS signal generator in one handheld unit. It is built for technicians, educators and hobbyists who need portable voltage, current and waveform analysis without carrying separate bench instruments.

Build Integration

The device runs on an internal 3000mAh rechargeable battery charged via a Type-C 5V/1A adapter, removing the need for mains cables during field work. Its combined architecture frees up bench space and reduces the number of probes and leads required for mixed-signal troubleshooting.

Thermals And Power

The FPGA plus MCU plus ADC hardware platform includes a built-in high-voltage protection module for safe operation up to the rated limits. A 2.8-inch 320 by 240 LCD provides clear readouts while the battery delivers approximately six hours of standby time between charges.

Questions about this item

How long will the built-in 3000mAh battery last during continuous oscilloscope use?

The manufacturer rates standby time at 6 hours; continuous oscilloscope operation will reduce that figure, so plan for shorter sessions or keep the Type-C charger handy.

How much heat or fan noise does the FPGA+MCU+ADC architecture produce during all-day bench work?

No fan is mentioned, so the unit runs passively; expect only modest warmth from the high-voltage protection module and the 2.8-inch 320×240 LCD during extended use.

Which probes or leads must I already own to use the oscilloscope, multimeter and signal-generator functions?

The oscilloscope needs BNC probes rated for ±400 V, the multimeter requires standard banana test leads for up to 9.999 A, and the signal generator outputs via BNC for its seven waveform types.
