The Keysight Agilent HP N5500A Phase Noise Test Set is part of the Keysight Agilent HP E5505A Phase Noise Measurement System. The Keysight Agilent HP 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.
