Noise XT today introduced the world’s first phase noise generator, setting the commercial standard for all phase noise calibration. The PNG-A (Phase Noise Generator) is small and light, weighing just 2 lbs. At under $3,000, every bench can afford one. The PNG-A is the first signal source to deliver a signal with mathematically computed phase noise in real time.
“There is no test industry standard for phase noise calibration,” said Guillaume De Giovanni, Head of Business Unit Noise XT. “This is a new type of instrument in the Phase Noise industry; no one has ever released such universal solution.” PNG-A’s applications are spread across the RF, microwave, and digital industries. Typical users are engineers in calibration labs or production test environments who need to speed up phase noise testing and calibration.
Features and technology of the PNG-A
The PNG-A is a small instrument that allows engineers and cal labs the opportunity to calibrate without wasting time building large equipment set-ups.
With the PNG-A, users can verify their phase noise analyzers, jitter analyzers, and spectrum analyzers, all in a few minutes.
The PNG-A generates an RF output that carries an extremely precise phase noise shape or jitter that can be measured by most instruments in the market today. This unique precision derives from full mathematical processing, leaving no room for analog inaccuracies.
The user can design the exact phase noise shape, according to the instrument to be tested. Or, the user can simply load one of Noise XT’s pre-loaded generic profiles. These profiles can be chosen specifically to test an oscilloscope, a signal source analyzer, or a spectrum analyzer with phase noise features. Remote settings are through Ethernet.
The phase and amplitude noise from the PNG-A does not rely upon temperature, time, humidity, or other environmental conditions to perform perfectly. The phase and amplitude noise are always correct.
“Having such predictable behavior allows test engineers to calibrate signal sources and phase noise analyzers anywhere they need it, all in a couple minutes. This can be done on a ship or an airplane, a secured lab, or any manufacturing facility, all without requiring bothersome logistics,” said De Giovanni.
Noise XT’s unique intellectual property is embedded in a complex FPGA. It has been engineered according to complex mathematical calculations; our internal architecture allows continuous verification of the generated signal. The virtualization of the signal generation allows great flexibility as the PNG-A can generate a programmable phase or amplitude profile.
The internal algorithms were developed by our Noise XT R&D team and verified by the development team. Successful validation has been accomplished using two different methods: first, by RF and microwave engineers using phase noise analyzers, and second, by independent mathematicians who studied and verified our mathematical models. These algorithms have never been encountered in any other commercial product to date.
