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.
