The Tektronix 82A04B Phase Reference Module is a high-performance timing and synchronization module designed for Tektronix Digital Serial Analyzers and Sampling Oscilloscopes. It enables extremely low-jitter measurements by establishing a phase reference from a continuous-wave (CW) clock, achieving system jitter of less than 100 fs RMS when paired with high-bandwidth sampling modules.
