[GreenKeys] 1khz reference tone...

[Kenneth Gartland]

'Morning all!

Looking for an on-line Internet source for a 1khz
unmodulated reference tone...

I wud like to calibrate an HP3551 test set, as I don't
have an alternate audio oscillator I can use to check it...

I thought sometime ago, it had been mentioned such
a test tone source was available, and was wondering
If any of you have used it for calibration etc...

Also, am wondering if such is available on-line,
can alternate frequencies be called up, say 2125hz etc.,
this wud be a great help in tuning audio filters etc.,
when building TU's...

Tks all!

Cheers!
