Saelig Company has introduced the Xprotolab, a mixed-signal oscilloscope with an arbitrary waveform generator housed in a tiny 1 x 1.6in (25 x 41mm) DIP module.

It can be mounted directly on a breadboard or a printed circuit board for in-situ testing and verification.

Based on Atmel’s ATXMEGA32A4 microcontroller, with 32Kb Flash, 4KB SRAM and 1KB Eeprom, the Xprotolab can also be used as a development board for the AVR’s XMega microcontroller.

The Xprotolab uses a 0.96in 128 x 64-pixel OLED display to provide the functions of an 8-bit mixed-signal oscilloscope with the simultaneous sampling of analogue and digital signals, providing two analogue channels and eight digital channels.

It also offers arbitrary waveform generator capabilities.

The maximum input voltage is +/-10V with a maximum sampling rate of 2MSa/s, giving an analogue bandwidth of 320kHz – more than enough for many servicing needs and experiments, according to the company.

Saelig added that most features found on today’s scopes are present in the Xprotolab – including an external trigger.

This can be used on any signal, trigger level adjust, voltmeter mode, XY mode, spectrum analyser and horizontal and vertical cursors.

Having logic analyser features also makes this miniature device extremely versatile, according to Saelig, and the 44kHz arbitrary waveform generator offers +/-2V sine, triangle and square waves, with control of amplitude, frequency, offset and duty cycle.

Four tactile switches are mounted to provide onboard function control, and the Xprotolab can be powered either via the micro-USB connector or with external +5V on the appropriate pin.

Scope features include: an advanced trigger (normal/single/auto), with rising or falling edge and adjustable trigger level; XY mode (plot Lissajous patterns or see phase difference between two waveforms); cursors (horizontal and vertical) with automatic waveform measurements; display (persistence, grid options and more); a spectrum analyser with different windowing options and a selectable vertical log; a meter mode with DC, average and frequency readout; and a protocol sniffer for UART, I2C and SPI.

The Xprotolab is priced at USD49 (GBP30).
