PN2060A/B Phase Noise Analyzer

[email protected]

Summary

The PN2060A Phase Noise Analyzer measures the amplitude, phase noise of high-performance RF sources. Carrier frequencies from 1MHz-120MHz are supported, and extremely, frequencies can be extended to 1GHz (only for reference, may not accuracy, and with a degenerated dynamic range).

Features

Independent input and reference frequencies from 1 to 120MHz

No phase-locking or measurement calibration required

Dual reference oscillator inputs allow cross-correlation measurements

Measurement results are saved to file automatically, matlab scripts are provided for post-data manipulation, raw data can be exported for further analysis

USB3.0 interface with high-speed data exchange, consume about 3.3W (5V, 650mA) totally

Allan deviation: two channel cross-correlation supported

TCPServer application available: can send data streams to other applications.

Measurements

Phase noise and AM noise at offsets from 0.01Hz to 1MHz and levels typically below -175dBc/Hz (10MHz floor)

One high quality USB3.0 cable is enough to complete data collection and power supply

Specification of PN2060B

Most of the parameters are the same with that of PN2060A. There are about 6-9dB improvement for the dynamic range compared with that of the pn2060a, and far end noise floor is typically below -180dBc/Hz (10MHz noise floor). The device consumes about 3.3W (5V, 650mA) totally. The size and weight are the same with that of the PN2060A.

The difference between square wave and sine wave: When measuring square wave, if it is not filtered, the noise (at about 100KHz-1MHz) will be raised about 3-5dB. The main components of the harmonics of the square wave are the 3th, 5th, and etc. So, appropriate filters should be adopted. For example, if a 24.576MHz Crystek (CCHD-957-25-24.576) is measured, a high quality low-pass filter with 30MHz bandwidth(3dB) should be inserted in the signal path.
