Advance H1B AF signal generator calibration - UK Vintage Radio Repair and Restoration Discussion Forum

Hello,
Does anyone have the calibration instructions for this or similar sig gen?
Particularly, on the front, what is the O-22V range for sine wave, Peak to Peak or RMS?
It seems the range can be altered by adjusting the preset inside the case.
Thanks

I have the (pdf)manual for the H1 Generator which inclues the H1/E & H1/NA if it helps. Its too big to post on the forum, PM me if you would like a copy.

Thanks for the offer but I have the manual from the internet.
Unfortunately it does not give the information I was after (or I didn't see it)

If it`s like the J1 the voltage is RMS into 600 ohms.

If it's like my H1 V amplitude is RMS, I think into 600r. Mine needed several resistors in the divider chain replacing. If you want exact amplitude readings replacent of the one tun pot with a precision 10 turn would be beneficial.

Good point about the pot - even using the 20 dB attenuator it was difficult to adjust for exactly -10dBm. (Vaguely remembered from 48 years ago)
