RECEIVER FREQUENCY ADJUSTMENT
Connect the Analyzer to the receiver under test, as shown in figure 4-6.
Set DISPLAY to Spectrum Analyzer (1.5 uV sensitivity). Enter the proper local oscillator frequency. Check the
receiver's local oscillator for approximiate frequency and spectral purity.
Change DISPLAY to Gen/Mon Mtr and FUNCTION to Monitor. Place pick up loop in close proximity to the
receiver so that the local oscillator signal is coupled to the Monitor input.
Change FUNCTION to Generate and enter the proper carrier frequency. Introduce sufficient signal level into the RF
input to fully quiet the receiver and adjust discriminator to zero volts DC for receivers requiring such an adjustment.
For receivers with quadrature or more critical detectors, adjust detector tuning control or local oscillator injection fre-
quency for minimum distortion or best SINAD performance.
5. For pagers with the battery saver feature, check the local oscillator for pulse operation without removing the unit
from its housing.
