Symmetricom’s 5120A brings a paradigm shift to the way that Single Sideband phase noise and Allan Deviation (ADEV) measurements are made. With the all-digital 5120A High Performance Phase Noise and Allan Deviation (ADEV) Test Set, measurements that used to be complicated and costly are now easier, more accurate, and more cost effective. And the recently introduced Internal Reference Oscillator Option makes testing even easier.

When using the optional low noise internal reference oscillator, the 5120A-01 enables accurate phase noise and ADEV measurements with a single connection, entirely eliminating the need for an external reference. Previously, a low noise reference was required at the exact test frequency, which was time consuming and costly; now measurements on devices between 1-30 MHz can be made with a single reference.

"The optional 5120A-01 is another significant advancement in the ease-of-use for Symmetricom's high performance phase noise and Allan Deviation test set," commented Dr. Samuel Stein, vice president of research and development at Symmetricom. "Highly accurate measurements can be made at the click of a button, all at a fraction of the cost of other available measurement tools. Without the tedious multi-step configuration or calibration routines, the optional low noise internal reference oscillator makes this test set the easiest to use in the world."

The culmination of over 20 years of research at world-leading laboratories, the 5120A allows customers to easily make highly accurate phase noise and ADEV measurements (down to -175 dBc/Hz and <3E-15 at 1 second, respectively) without any pre-calibration or pre-configuration, unlike other test instruments. While other commercially available phase noise and ADEV test instruments require multiple pieces of equipment and must be precisely calibrated before a measurement, the single box 5120A eliminates this process entirely.

"A calibration by the National Institute of Standards and Technology (NIST) confirmed that the submitted 5120A's measurement accuracy was better than 1 dBc/Hz at frequency offsets between 0.1 and 100,000 Hz," commented David Howe, project leader for Time and Frequency Metrology at the Time and Frequency division of NIST.
Typically used for short-term stability measurements of high precision oscillators and atomic clocks, Symmetricom time and frequency measurement instruments perform direct digital measurements of the device under test, enabling accurate results to be obtained in a matter of seconds. The 5120A and 5120A-01 Phase Noise and Allan Deviation Test Sets are available immediately.
