Spectrum Analyzer Function (Option 07)
The spectrum analyzer with synthesized local covers
a frequency range of 10 MHz to 3 GHz with a resolu-
tion of 1 Hz. In addition to a C/N of –115 dBc (100 kHz
offset), the RBW can be set to 300 Hz to 1 MHz, the
VBW to 3 to 100 kHz, and the sweep time in the fre-
quency domain to 100 ms to 1000 s (1 ms to 1000 s in
time domain).
High-Accuracy Measurement
The total level accuracy is an astonishing ±1.5 dB due
to the analyzer’s excellent linearity, and the level cali-
bration function. Moreover, the average noise level is
just –85 dB max. (at 10 MHz to 1 GHz), and the sec-
ondary harmonic distortion is –60 dB max. (100 MHz
to 1.5 GHz).
Convenient Functions
The analyzer has a full lineup of useful functions
including marker, delta marker, and gate sweep func-
tions. It also has advanced displays such as average,
max. hold, cumulative and overwrite. Trace A and
Trace B can be measured on a dual screen in the fre-
quency domain, along with noise power, C/N, occu-
pied bandwidth, adjacent channel power, and average
power of burst signal.
