DESCRIPTION:
The FM Driver high frequency offset is adjusted for zero volt drive with no FM modulation
applied. A delay-line discriminator is used to detect and display FM modulation on an
oscilloscope. Adjustments are for best overall frequency response from DC to 10 MHz.
Compliance to a specification of f 3 dB is checked between DC and 2 MHz.
