Fast device tune measurement
Description: Allows simultaneous calibration of a device’s Tx output power and Rx input level
across level and frequency in a single sweep (per frequency band). The device must operate
in a test mode which forces it to transmit a predefined series of power steps at various uplink
frequencies, and also forces it to simultaneously tune its receiver to perform measurements
(such as RSSI) of the test set’s signal at various downlink frequencies and power levels

Input frequency ranges: 698 to 1000 MHz, 1400 to 1500 MHz, 1700 to 1990 MHz,
and 2480 to 2580 MHz
Tx power measurement input level range: –61 to +28 dBm/3.84 MHz
Tx power measurement level change between adjacent steps:
–– < 20 dB for 20 ms step size
–– < 10 dB for 10 ms step size
Tx power measurement accuracy (at +10 degrees from calibration temperature): < ±1.0 dB
Rx level output range at RF IN/OUT port: –109 to –15 dBm/3.84 MHz
Rx level output range at RF OUT ONLY port: –109 to –7 dBm/3.84 MHz
Rx level change between adjacent steps: < 20 dB
Rx level accuracy with W-CDMA modulation: < ±1.1 dB
Rx level setting: < 5.1 ms to be within 0.1 dB
Concurrency capabilities: Fast device tune measurements cannot be made concurrently
with other measurements
