PNG-A Adjustable Phase Noise Generator
The PNG-A is a high precision generator used in Test and Measurement instruments calibration. It is a Signal Generator with precisely computed phase and amplitude noise characteristics. With its wide frequency offset range, 1Hz to 1 MHz offset, and its programmable Phase and Amplitude noise in real time, this is the ideal standard to calibrate phase noise analyzers, Signal Source Analyzers and Spectrum Analyzers.
The PNG-A can also be programmed in Random and Deterministic Jitter in order to test Oscilloscopes or even test clock recovery systems or receivers in the presence of noise or jitter. Much more flexible than traditional noise sources; the PNG-A allows the user to tailor the noise shape and its Phase and Amplitude distribution.

Noise Shape
The PNG-A is based on Real-Time continuous generation of pseudo-random noise and sine waves. Those noise elements can be applied to phase, amplitude and frequency internal modulation, separately or all at the same time.
Phase Noise can carry 3 types of combined shapes
- White noise (flat, horizontal)
- Brownian noise, also called Red noise (1/f2 or -20dB/decade down slope)
- 1x Discrete spurious
Amplitude Noise can carry 3 types of combined shapes
- White noise (flat, horizontal)
- 1x Discrete spurious
- Calibration
- Verifcation
- Adjustable phase noise reference
