General Information
N5500A Overview
The Agilent N5500A Phase Noise Test Set is part of the E5505A Phase Noise
Measurement System. The N5500A performs phase noise measurements with
the addition of baseband analyzers and software. Carrier frequencies range
from 50 kHz to 1.6 GHz with offset frequencies of 0.01 Hz to 100 MHz.
The phase detector input power at the SIGNAL input is specified at
0 to +23 dBm, and at the REF INPUT connection is +15 to +23 dBm. The NOISE
input for noise sources or external detectors ranges in frequency from 0.01 Hz
to 100 MHz with a 50 ohm input impedance and 1 Volt peak max.
There are three baseband analyzer outputs: (ANALYZER) <100 kHz,
(ANALYZER) <100 MHz and RF ANALYZER. The MONITOR output is used for
observing time domain phase noise on an oscilloscope. The TUNE VOLTAGE
output is used for tuning a VCO in a phase-locked measurement.
The rear-panel TRACK GEN and CHIRP SOURCE inputs are used for verifying
phase-lock-loop suppression. There are several available low pass filters:
100 MHz, 20 MHz, 2 MHz, 200 kHz and 20 kHz. The AM blocking filter is used
for an external AM detector (or the internal AM detector for Option 001). The
Decade spaced low pass and high pass filters range from 1 Hz to 100 kHz, and
are used to limit the bandwidth of noise applied to the baseband analyzer.
