Anapico APPH6000-IS400 5 to 400 MHz Phase Noise Tester

Anapico APPH6000-IS400 5 to 400 MHz Phase Noise Tester
Manufacturer: Anapico

The APPH6000-IS400 provides fast and accurate measurements of SSB phase noise, amplitude noise, or baseband noise.

The APPH6000-IS400 is a very compact, fully self-contained instruments with cross-correlator engine and internal low noise reference sources to enable fast and accurate “one-click” measurements of a variety of sources.  The instrument can be configured to meet user requirements: select-able internal or external reference source, phase detector models, and frequency offset ranges. Two channel cross correlation is also supported for lowest noise measurements.

It is a compact and powerful instrument available with LAN (VXI-11), USB.

Platform independent intuitive graphical user interface (GUI), API library, and powerful SCPI command language set is available.
