    If there is one thing you can get used on ebay or the flea market, it
    is a frequency counter. The only drawback is size. Newer means compact.
    I don't believe there have been any real advances in counters over the
    years. It is a very basic task.
  3. SRS make a good one, but not at the cheap end:
    The Rubidium version is flightfully expensive. It's actually much
    cheaper to get the SR620 & a seperate Rudibium standard than it is to
    get the SR625.

    I'm running that HP one with an SR725 SRS Rubidium standard at the
    moment, very nice combination. The HP GPIB Excel software plug-in is a
    bit buggy, but great for automated measurements straight into Excel
    without mucking around.

  4. Do you have an in house frequency standard, and Distribution
    Amplifier? I built a 1 in, 32 out DA for Microdyne for our GPS derived
    10 MHz standard. I used National LH0002, but only because I had a card
    cage with eight boards with four chips per board. It made accurate
    measurements a lot easier when all the equipment that used an external
    reference were locked together. National (and others) have modern SMD
    buffer amps that would do a great job. If you look at the price of
    commercial DAs, you might want to add one to your product line.

    Service to my country? Been there, Done that, and I've got my DD214 to
    prove it.

    on this year's tax. This is a slow week for business so great for buying
    equipment and reducing net income.
