help need a frequency standard

Tia

Any other ideas for a precision cal frequency?

WWV? However you will need a receiver for whatever frequency you choose? Bob AZ

How precisely do you need to calibrate your frequency counter? Back in the days of network TV, before cheap time base correctors were common, the colour burst oscillator was locked to a very stable rubidium standard. This is no longer the case. The oscillator in your TV is probably no more stable than the oscillator in your frequency counter.

In most parts of North America on the electrical grid, your wall outlet frequency will be 60 Hz plus or minus 0.02 Hz most of the time, and over a day probably averages 60 Hz +/- 0.001 Hz if you let the counter run long enough.

I do a rough and ready check of my frequency counter by zero-beating a signal generator with WWV (or CHU), which should be good for about 1 part in 10 million (you should be able to zero-beat within less than 1 Hz). I tune in WWV on a shortwave receiver, fire up the signal generator and set its output level high enough to be heard on the receiver, and measure the frequency at the output of the generator.

There are supposed to be GPS-disciplined portable frequency standards out there; I've no idea what these cost but they would be reasonably stable calibration sources.

I know what you can do, you can buy something from my company if you would like.

We make Frequency Standards along with other things as well.

send me an email if you still wish to pursue this.

Zero beat your r.f. signal generator to WWV while obvserving the frequency of the generator output as shown on your frequency counter. If excess error is observed, adjust the capacitive loading on your frequency counter's xtal oscillator until the error essentially zero.
