Section 4 RF Testing

4.2.11.4 Frequency Tolerance Procedure

NOTE:

The operating frequency of 719 MHz is for U.S. operation. Qualcomm may
define other UHF frequencies for international operation.

4.2.11.5 Frequency Tolerance Test Results

Step

Procedure Description

Expected Observation

1

Generate a CW tone as per the
instructions in Appendix B.

2

Using a frequency counter (or a
spectrum analyzer) measure the fre-
quency of the tone coming out of the
Exciter for 30 minutes (Provide the
frequency counter/spectrum ana-
lyzer with a reference signal derived
from the same GPS signal that the
Exciter has).

The maximum deviation of the car-
rier tone from 719000000 should be
less than ±1.0 Hz

3

Set FLO FPGA, SFN mode = Off.
Also, increase the SFN limit to 500
microseconds. Remove the 1PPS
signal, and using the frequency
counter/spectrum analyzer measure
the frequency of the tone overnight/
24 hours.

The maximum deviation of the car-
rier tone from 719000000 should be
less than ±10.0 Hz

Expected results

Result (circle)

Maximum deviation with GPS signal is less than +/- 1.0 Hz.

PASS FAIL

Maximum deviation without GPS signal is less than +/- 10.0

Hz.

PASS FAIL
