QRP and homebrew by DL2YEO

“The electronics industry uses several methods for labelling front panels and enclosures, including screen printing, press forming, erosion, lasers etc.. The common factor of these techniques is that they are generally beyond the home constructor. Having these parts specially made commercially can be very expensive, and the only alternative is standardized scales and fonts.”

XScopes Xminilab and Xprotolab

The XScopes Xminilab and Xprotolab are a combination of three electronic instruments: a mixed signal oscilloscope, an arbitrary waveform generator, and a protocol sniffer; all housed in a small breadboard friendly module. The XScopes can also be used as development boards for the AVR XMEGA microcontroller.

Mixed Signal Oscilloscope: Simultaneous sampling of 2 analog and 8 digital signals. Meter Mode: VDC, VPP and Frequency readout. Arbitrary Waveform Generator with advanced sweep options on all the wave parameters. Spectrum Analyzer with different windowing options and selectable vertical log and IQ visualization.
