19 | Keysight | M8195A 65 GSa/s Arbitrary Waveform Generator and M8197A Multi-Channel Synchronization Module - Data Sheet
Reference clock input
The clock reference input is provided on the front panel of each module. The clock reference input of the M8195A is used as the clock
reference for all four channels of that M8195A. The clock reference input of the M8197A synchronization module is used as the clock
reference for all channels of all M8195A that are combined in a synchronous system.

1. Reference clock output phase shifts when the variable delay is changed.
2. For M8195A: Reference clock output remains unchanged when the variable delay is changed.
3. Warm-up time 2 minutes min.
4. fSa = 64 GHz; reference clock source: internal.
