Output RF Spectrum Measurement

Specifications

(Requires Option 006)

After one timeslot, 577 µs, from an isolated receiver hop

trigger in the GSM frequency bands.

Input levels for optimum dynamic range

(RF In/Out connector):

+7, +17, +27, +37 dBm

(from 880 to 960 MHz)

-3, +2, +7, +12, +17, +22, +27, +32 dBm

(from 1710 to 1990 MHz)

Input frequency setting range: ±10 kHz

Input level setting range: ±3 dB

Supplemental characteristics

Log linearity: ±0.4 dB

Amplitude flatness: ±1.0 dB

Amplitude resolution: 0.4 dB

Dynamic range (dB): This describes the spectrum analyzer

resolution bandwidth filter used when measuring output

RF spectrum. The dynamic range of the measurement will

be a combination of this filter response and the modulation

spectrum of the incoming signal.

Offset (kHz)

100 200 300 400 600 800 to 1800

Range (dB) 24 42 53 60 63 64

When using output RF spectrum due to the ramping

measurement, the dynamic range is decreased by 12 dB

(due to peak hold).
