23 | Keysight | E1966A 1xEV-DO Terminal Test Application - Technical Overview
1xEV-DO RF Generator (Continued)
RF generator level accuracy is derived from 99th percentile observations with 95 percent confidence
(corresponds to an expanded uncertainty with a 95 percent confidence (k=2)) at ambient conditions,
then qualified to include the environmental effects of temperature and humidity.

Isolation (from RF out only port Typically > 40 dB
to RF in/out when the RF source
is routed to the RF out only port)
AWGN channel relative
level range
Settable to ±35 dB relative to the total power (user-set 1xEV-DO cell
power plus AWGN power) with 0.01 dB resolution
Relative AWGN level accuracy
Typically < ±0.2 dB for AWGN levels of less than or equal to ±20 from
the total set RF power. Useable to ±35 relative levels from total RF
power with degraded relative level accuracy
