Inter-system handover
Dual-mode functionality is required for most W-CDMA phones, as GSM is an integral part
in the majority of devices shipping today. Inter-system handovers provide a means to validate
dual-mode performance at your desk instead of roaming on a real network. When operated
in conjunction with compressed mode, this feature can very closely emulate the basics of a
real handover as made on the network.
–– Blind handovers from W-CDMA to GSM
–– Configurable landing GSM cell
–– Test control to GSM voice
–– W-CDMA AMR voice to GSM voice

RF generator level accuracy is derived from the 99th percentile observations with 95%
confidence (corresponds to an expanded uncertainty with a 95% confidence (k=2))
at ambient conditions, then qualified to include the environmental effects of temperature
and humidity.

AWGN off:
–– < ±1.1 dB (typically < ±0.65 dB), at –109 to –15 dBm/3.84 MHz and
–– < 2300 MHz
–– < ±1.5 dB (typically < ±1.0 dB), at –109 to –15 dBm/3.84 MHz and ≥ 2300 MHz
