This unit provides the necessary standard signals for measuring frequencies when using any general communications receiver.
Easy calibrated against WWV to provide an accuracy of 1 x 106 for measuring the frequency of harmonics of FM subcarrier frequencies.
An internal rechargeable battery and charger make it right for field or bench use.
All transistor circuits provide outputs at 1 MHz, 100 kHz and 10 kHz. Level of signal can be set with gain control.
