FNIRSI DSO-TC4 3-in-1 portable oscilloscope with transistor tester and 10 MHz signal generator.
FNIRSI DSO-TC4 combines three functions - a digital oscilloscope, an electronic component tester and a signal generator.
Main features of the 3-in-1 oscilloscope
- Three devices in one : oscilloscope, component tester and signal generator in one compact housing, saving you space and time
- Precise signal analysis : 10 MHz bandwidth and 48 MSa/s sampling rate allow you to conveniently observe waveforms in real time
- Safe high voltage measurements : Anti-Burn protection and 1:1 and 10:1 probe support increase work safety
- Versatile Signal Generator : 13 waveform types with adjustable frequency and amplitude for testing various systems
- Automatic measurements with one click : quick reading of parameters such as RMS, Vpp, frequency or duty cycle
- Easy-to-read color screen : clear 2.8" TFT display with brightness adjustment ensures comfortable work
- Mobile design : built-in 1500 mAh battery and USB Type-C charging allow you to work without a constant power supply
What measurements can you take?
In oscilloscope mode, the FNIRSI DSO-TC4 enables the analysis of AC/DC coupled signals and the rapid capture of waveforms using auto, normal, and single-shot triggering modes. The device can measure values such as max, min, average, RMS, Vpp, frequency, period, and duty cycle . The HOLD function makes it easy to freeze a waveform and analyze the results. The integrated component tester automatically recognizes and measures the parameters of passive and semiconductor components such as diodes, Zener diodes, transistors, MOSFETs, JFETs, IGBTs, SCRs, resistors, capacitors, and inductors. The signal generator allows you to simulate circuit operating conditions, simplifying testing of inputs, filters, and audio and control paths.
Convenient operation and mobile power supply
The 2.8" TFT color screen with adjustable brightness ensures clear readings of waveforms and measurement results. The intuitive control panel allows for quick switching between operating modes . AUTO mode helps instantly stabilize the signal image. A screenshot function simplifies results archiving and subsequent analysis. The USB Type-C port is used for charging and data transfer. The built-in 3.7 V / 1500 mAh battery ensures mobile operation, while automatic sleep mode extends the operating time between charges. This makes the device suitable for both service desk and field work.
The generator supports 13 waveform types.
The 1500 mAh battery and USB Type-C charging allow you to work without a constant power supply.
