Chris Ford has an encoder simulator in lab3, with documentation here:  UDP Encoder Interface (rix Mono Encoder).  He also has committed lab3-caf-encoder.cnf to lcls2 GitHub in psdaq/psdaq/cnf/.

High Rate Mono Encoder Interpolation Options

Goal: keep the parallelization happy (both ami and mpi-psana) so that every shot has an encoder value (either real or interpolated)

Note that the encoder can be used to generate XAS spectra with APD's, which are MHz devices.  That's why we need high rates.

• ~5kHz of measured data is roughly the maximum readout rate
• interpolation will make the data better (if the "noise" on the plot below is really noise, Georgi feels it is too high frequency to be real, but he's not certain)

Example motor motion:
