Chapter 4, Description of Fields
Fields
In addition, the post detection bandwidth is set at <20 Hz and >99 kHz in the
Active, Register and Page states, and 300 Hz to 15 kHz when in the Connected
state. This is done to ensure that no signaling tones are filtered off. This wide post
detection bandwidth allows more noise to be introduced into the measurement
process which affects the measured deviation.
Given these conditions it is recommended that FM deviation measurements
requiring full Test Set FM deviation accuracy be made on the
ANALOG MEAS
screen or the
AF ANALYZER screen. The audio frequency gains stages are set to
autorange while on these screens and post detection filters can be selected to
optimize deviation measurements.

Frame Clock
This field is used to select the CDMA frame clock output frequency on the rear-
panel CDMA CLOCK MUX OUTPUT.
Operating Considerations
The CDMA frame clocks provide the CDMA timing references for generating and
demodulating CDMA signals.
The CELLSITE/TRIGGERS connector, a rear-panel miniature D-type 15-pin
connector provides all of the above frame clock outputs simultaneously. The
timing of these frame clocks may be offset slightly from the timing of the CDMA
CLOCK MUX OUTPUT’s frame clocks due to propagation delays.
