RS Components (RS), the trading brand of Electrocomponents, has introduced a two-channel oscilloscope that has a footprint approximately the size of a passport with a thickness of 19 mm.
The RS Pro 2205A‑20 is the smallest oscilloscope in the RS Pro range. Connected and powered via USB it offers a bandwidth of 20 MHz and features an arbitrary waveform generator. These features make it the perfect scope for engineers on the move: small enough to fit into a laptop bag while offering all the features and performance of a traditional bench-top oscilloscope, said the company. The serial decoding function (CAN, LIN, SPI, I2C, I2S, UART and more) presents results in tabular and color-coded graphical formats, with filtering, search, and export options.
The specifications include a maximum sampling rate of 200 MS/s, software-enhanced resolution up to 12 bit, and high-speed USB streaming up to one million samples pe rsecond for waveform captures of up to 100 million samples in length. Input range is selectable from ±50 mV to ±20 V. The signal integrity, with less than 150‑µV RMS noise and -50‑dB harmonic distortion, makes it suitable for a range of analog and digital applications. The built-in signal source can act as a regular signal generator (sine, square, triangle, and others) with programmable sweep or as a 12‑bit 1,5 million samples per second full-function arbitrary waveform generator.
The two-channel scope includes an FFT spectrum analyzer, 16‑Ksamples of segmented capture memory, math channels, automatic time-domain and frequency-domain measurements. Additionally, it includes color persistence, XY display modes, and mask limit testing. Advanced digital triggering produces stable waveforms with single‑LSB threshold resolution. The free software for Microsoft Windows 7, 8, and 10 runs on a PC and can be resized to use as much or as little of the screen as required.
