Product Overview

AGILENT / KEYSIGHT N5500A

The Keysight / 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 pecified 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)

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.

Option 001 adds an input attenuator, input switching, an AM detector, and a microwave phase detector to the test set. The input attenuation ranges from 0 to 35 dB in 5 dB steps.

The RF ANALYZER output can view either an input signal of up to 26.5 GHz or baseband noise. The SIGNAL input can be switched to AM detector, RF phase detectors, microwave phase detector, or an external microwave downconverter. The IF signal from the downconverter is switched to the RF phase detectors.

The N5500A Option 201 adds a microwave phase detector to extend the carrier frequency range to 26.5 GHz. The microwave phase detector frequency ranges from 1.2 GHz to 26.5 GHz. The microwave phase detector input power at the µW SIGNAL input ranges from 0 to +5 dBm and +7 to +10 dBm at the REF INPUT connections.
