Tektronix 82A04 Phase Reference Module 2-25 GHZ
Product Classification：RF Test
The 82A04 Phase Reference Module extends the capability of the DSA8200 digital serial analyzer sampling oscilloscope mainframe 1 by providing extremely low jitter/low drift sample position information to the mainframe. This sample position information is based on the phase of a clock the user provides to the 82A04 input.
The benefits of using the sample position information based on a clock signal are two-fold:
An extremely low jitter of <200 fsRMS (typical).
The possibility of a triggerless acquisition.
The typical application is the acquisition and analysis of very high speed optical and electrical signals in high-speed communication devices and systems, and similar areas.
The 82A04 together with the DSA8200 implements the phase reference timebase functionality in a novel way, giving the user the freedom to select from timebase and acquisition modes without compromise. Any phase-reference frequency within the operating range is accommodated, and even the advanced features, such as FrameScan®, remain available. The separate DSP per acquisition slot architecture of the DSA8200 enables the acquisition rate in the phase reference mode to reach over 40 kS/s.
The 82A04 Phase Reference Module is also compatible with the CSA8200 Communications Signal Analyzers
and the TDS8200 Digital Sampling Oscilloscopes.
