Cleverscope CS448 Isolated Channel Oscilloscope

The CS448 is a 4-channel, high CMRR, fully isolated oscilloscope designed to measure signals in full or three-phase power electronic switching bridges. With 14-bit resolution, 200 MHz bandwidth, an isolated signal generator, and advanced digital inputs, it's ideal for gate drive, power, EMC, and control system measurements. Two units can be linked for 8-channel coherent sampling..

  • Special Features
  • Specification

The CS448 enables accurate and safe measurement in high-voltage, fast-switching environments. It includes isolated signal paths, ensuring precise data capture with minimal interference. Each channel supports ±0.8V and ±8V input ranges (extendable using probes), and the unit supports a dynamic range of 100 dB with 14-bit resolution.

The isolated signal generator supports up to 65 MHz outputs, with programmable arbitrary waveforms (future UI support). USB 3.0 and SFP-based Ethernet allow high-speed communication. Two FPGA-based trigger systems offer flexible analog/digital logic conditions for event capture.

The software includes spectrum analysis, FRA, and full protocol decoding (I2C, SPI, UART), with features for streaming, logging, and live MATLAB/Excel interfacing.

Advanced measurement use cases include:

  • Gate charge and conduction loss in VSDs

  • EMI spectrum testing using 100x probes

  • High-speed switching analysis (e.g., 500V in 10ns)

  • Frequency response of power supply and components

(Some advanced waveform generation and real-time filtering features are pending software updates.)

  • 4 Fibre Optic Isolated Channels (1kV Cat III, 2kV Cat II)

  • 14-bit ADC Resolution, 200 MHz Bandwidth

  • Signal Generator: DC–65 MHz, Arbitrary Waveform Capable

  • 8 Isolated Digital Inputs (1kV working, 100 kV/us transient immunity)

  • USB 3.0 (130 MBps) and Ethernet (Copper & Optical)*

  • Advanced Trigger System (AND/OR/XOR logic, time sequences)

  • Low Channel Noise (200 uV rms @ ±0.8V range)

  • High CMRR: >100 dB @ 50 MHz

  • SFP-based Ethernet & SD Card Storage*

  • Link Port for Cleverscope accessories & 8-channel daisy chaining

  • Spectrum Analysis, FRA, and Streaming Support

  • Self-calibration and probe compensation tools
