17 | Keysight | TD-SCDMA_GSM Fast Switch Test Application - Technical Overview
Spectrum monitor
Measurement modes: Swept mode or zero span
Frequency ranges: Although the spectrum monitor is available at any frequency sup-ported by
the test set, specifications apply only inside of the calibrated bands: 450 to 496 MHz, 700 to
800 MHz, 810 to 960 MHz, 1.7 to 1.99 GHz, and 2.48 to 2.58 GHz
Frequency spans, resolution bandwidth range: Span and RBW can be independently set, except
for zero span; zero span can only be set with the RBW combinations shown below. (Specifi-
cations only apply for span and RBW combinations shown in the following table):

RBW filter types: Flattop in swept mode, Gaussian in zero span
Zero span sweep time: Settable from 50 μs to 70 ms
Zero span offset time: Settable from 0 to 10 s
Reference level range: Settable from –50 to +37 dBm or automatically determined
Averaging capabilities: Settable between 1 and 999, or off
Marker functions: Three independent markers with modes of normal, delta, and off; opera-
tions are peak search, marker to expected power, and marker to expected frequency
Concurrency capabilities: Spectrum monitor analysis can be performed concurrently with all
measurements
Supplemental characteristics
Typical level accuracy

> –10 dBm and RBW < 5 MHz,
< ±2 dB for signals within 30 dB of a reference level
< –10 dBm and RBW = 5 MHz using 5 averages,
< ±3.5 dB for signals > –70 dBm and within 50 dB of a reference level
< –10 dBm with RBW < 5 MHz
