E6833A Datasheet, PDF (5/6 Pages) Agilent(Hewlett-Packard) – Wireless Communications Test Set

Fast Device Tune Measurement
Measurement method
Allows simultaneous calibration
of a device’s transmitter output
power and receiver 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
reverse link frequencies, and
simultaneously tune its receiver
to perform measurements (such
as RSSI) of the test set’s signal
at various forward link
frequencies and power levels
Measurement range

within band
Measurement accuracy¹ (within 45 dB of expected power with
< 48 hours warm-up before self alignment initiation)
–54 to +28 dBm/1.23 MHz < ±0.75 dB, typically < ±0.3 dB
–61 to < –55 dBm/1.23 MHz < ±0.85 dB, typically < ±0.3 dB
RF source output level range
RF in/out port
–115 dBm/1.23 MHz to
–15 dBm/1.23 MHz
RF out only port
–115 dBm/1.23 MHz to
–5 dBm/1.23 MHz
Composite absolute output level accuracy (< ±10 °C and
< 24 hours from the last alignment, –108 to –15 dBm/1.23 MHz)
RF in/out port
< ±1.0 dB, typically ±0.65 dB
RF out only port
< ±1.0 dB, typically ±0.65 dB
RF output level settling
< 1 ms to be within 0.1 dB of the
final value
1. Additional accuracy error when using RF OUT ONLY port is < ±0.1 dB.
