1xEV-DO Analyzer (Continued)
Time response of open loop power control measurement
Input frequency ranges
Measurement method
411 to 420 MHz
450 to 484 MHz
821 to 934 MHz
1700 to 1980 MHz
Measures the open loop power versus time response of a mobile to
a 20 dB step in the test set’s cell power. User must set the ACK channel
fixed mode bit to Off and set AT directed packets to 0% in order to
achieve valid measurement results

and within ±9 dB of the expected input power
Confidence limit range
Definable from 80.0 to 99.9% and Off
PER reported parameters
Intermediate results
PER, number of FTAP packets sent, number of FTAP packets received,
number of FTAP physical packet slots, and number of FTAP MAC
packets received
Final results
PER, number of FTAP packets sent, number of FTAP packets received,
number of FTAP physical packet slots, number of FTAP MAC packets
received, and one of the following: passed confidence limit, failed
confidence limit, or maximum frames
Concurrency capabilities
PER measurements can be made concurrently with all 1xEV-DO
measurements that can run while in a FTAP connection
