Mixed-signal oscilloscope for in situ testing
Saelig
Xprotolab
Saelig has introduced Xprotolab, a mixed-signal oscilloscope that can be mounted directly on a breadboard or pcb for in situ testing and verification.
Offering an arbitrary waveform generator housed in a 1 x 1.6in DIP module, Xprotolab uses a 0.96in 128 x 64 pixel OLED display to provide the functions of an 8-bit mixed-signal oscilloscope with simultaneous sampling of analogue and digital signals, providing two analogue channels and eight digital channels.
It also offers Arbitrary Waveform Generator capabilities.
Based on Atmel's ATXMEGA32A4 microcontroller, with 32KB Flash, 4KB SRAM, 1KB EEPROM, Xprotolab can be used as a development board for the AVR's XMEGA microcontroller.
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.
Features: trigger 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 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 Xprotolab can be powered either via the micro-USB connector or with external +5V on the appropriate pin.
Scope features include: 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; spectrum analyser with different windowing options and selectable vertical log; meter mode with DC, average and frequency readout; Protocol Sniffer for UART, I2C, SPI.
