Custom Keysight N5511A System for Testing Phase Noise Suppliers, Exporters

The gold-standard Keysight E5500 phase noise measurement equipment has been replaced by the Keysight N5511A phase noise test system (PNTS).

Product Description

The Most Adaptable Measurement Method

Utilizing standalone equipment, the N5511A PNTS modular instrument architecture offers the greatest sensitivity, broadest capabilities, superior frequency offset range, and outstanding overall value for phase noise measurements. Any electronically frequency-tunable reference source can be used with it, allowing for improved performance when newer, higher-performance signal generators hit the market.

Frequently Asked Questions

Q:What are the main measurement capabilities of the N5511A Phase Noise Test System?

A: The N5511A provides comprehensive measurement capabilities, including Phase noise, AM noise, Residual noise, Baseband noise, Frequency/Power/Phase transient, VCO characterization, Full span spectrum analysis, Vector network analysis, and Clock jitter analysis.

Q:What is the maximum offset frequency range and how is it extended?

A: The system supports a maximum offset frequency of 160 MHz. It covers a range from 0.01 Hz to 160 MHz when using an external signal analyzer.

Q:Which frequency models/options are available for the N5511A system?

A: The N5511A offers three frequency range options: N5511A-503 (50 kHz to 3 GHz), N5511A-526 (50 kHz to 26.5 GHz), and N5511A-540 (50 kHz to 40 GHz).

Q:What is the performance advantage of the Dual-channel (Option N5511A-CH2) model?

A: The dual-channel option enables dual-channel cross-correlation, which dramatically increases measurement sensitivity, approaching the thermal noise limit kT (-177 dBm/Hz).

Q:Does the system include an internal reference source or require an external one?

A: The system uses an external reference source. This flexible design allows you to interface the N5511A with any electronically frequency-tunable reference source to optimize sensitivity as technology improves.

Q:What is the absolute phase noise sensitivity of this system?

A: The system achieves an absolute phase noise sensitivity of -153 dBc/Hz (at 10 GHz with a 10 kHz offset, Xcorr=1) and a phase noise sensitivity down to -200 dBc/Hz with a +23 dBm input signal.
