Adjustment Description
Number
16 Adjusts the FM demodulation for a peak response.
5 Adjusts Limiter Phase for peak response.
5 Minimizes error to Top of Screen.
5 Minimizes Linearity Fidelity error.
4 Sets calibration oscillator output power (nominally
−35 dBm). This power is injected into
during the AUTO IF ADJUST routines.
3 Adjusts center frequency of first stage of LC
bandwidth filter to 10.7 MHz.
3 Adjusts center frequency of second stage of LC
bandwidth filter to 10.7 MHz.
3 Adjusts center frequency of third stage of LC
bandwidth filter to 10.7 MHz.
3 Adjusts center frequency of fourth stage of LC
bandwidth filter to 10.7 MHz.
4 Adjusts the attenuation of the reference 15 dB
attenuator for 15 db between minimum and
maximum attenuation.
