Feature-packed PCSGU250 comes with everything you need for a USB-powered lab. PCLAB2000-LT software for two channel oscilloscope, spectrum analyzer, recorder, function generator and bode plotter. With the generator, you can create your own waveforms using the integrated signal wave editor. For automated measurements, it is even possible to generate wave sequences, using file or computer RS232 input.

Product Reviews

  • "Pretty Neat Gadget" by danhesselbach on 6/21/2012
    Overall: 4 out of 5

    I needed a function generator for one project and this did the job. I checked the wave output on a small scope that I have and also on the scope provided by the device. The two scopes agreed that the function generator output voltage was out of calibration by a small amount but it can be easily tweaked. So probably not great for lab work, but you can take it to the job site and not have to worry about the frailty of much more costly equipment.

  • "It works as advertised" by mgrady on 8/20/2011
    Overall: 4 out of 5

    The PC software is quite friendly for one familiar with a traditional oscilloscope.
