Phase Noise & Allan Deviation Test Sets
Easier, More Accurate and More Cost-Effective Measurements
Symmetricom’s digital, state-of-the-art digital test sets bring a paradigm shift to the way that phase noise and ADEV measurements are made. What was once a complicated and costly procedure has now been made easier, more accurate, and more cost effective. Typically used to characterize high precision oscillators and atomic clocks, our Phase Noise & Allan Deviation test sets are simple one-box solutions that characterize even the lowest noise references more accurately than ever before.
The all-digital 5120A High-Performance Phase Noise and Allan Deviation (ADEV) Test Set with Ultra Low Noise Floor transforms the way accurate phase noise and Allan deviation measurements are made. This simple one-box solution makes fast yet accurate single sideband (SSB) phase noise and ADEV measurements at the click of a button, all at a fraction of the cost of alternative solutions. What used to be complicated and costly are now easier, more accurate, and more cost effective.
The one-box digital 5115A Phase Noise and Allan Deviation Test Set directly samples the RF inputs and performs all phase difference, phase noise, and Allan deviation calculations numerically. It is self-configuring, self-calibrating, requires no external phase-lock loop, and allows the oscillator under test and reference to have different frequencies. No additional hardware is required.
The 5125A makes accurate phase-noise measurements on signals from 1 MHz to 400 MHz, covering the full range of the most commonly used frequency references. The 5125A, which requires absolutely no configuration, displays measurement results seconds after the Start button is pressed.
The 3120A makes accurate phase-noise and ADEV measurements on signals from 0.5 MHz to 30 MHz, covering the full range of the most commonly used frequency references. The 3120A, requires an external reference and computer to be used with the 3120A Phase Noise Test Software to make measurements. Additionally, customers can purchase software upgrade options to make AM noise, Signal Statistics - HDEV, MDEV, TDEV and jitter measurements, to set test limits and to use it as a frequency counter.
