  2. You work for them or have any relationship to the company?

    It should do.
    Inspecting the Jpeg of their PCB, it looks like they're using a couple of
    AD9833's DDS chips and some CMOS switches to make the quadrature phase
    measurements.
    With the advent of cheap DDS chips and micros with built in ADCs it looks
    like all the component testing makers have/must, move in this direction.
    G.P. AC component bridges now looking more and more like the Victorian
    artefacts that indeed they are.
    The clever bit is the amount of programming they've been able to stuff
    inside that micro.
    Looks a really nicely designed bit of kit, at a decent price.
    (their max capacitance of '900mF' looks out of place. More in keeping if
    '9mF')
    regards
    john
