 Purpose          Record RF system jitters vs. average gate length and store / archive data
-Preconditions    - AVG gate for REFxx start = 0.1us, stop = 0.105us
-                 - based on the current RF rep rate and pulse-to-pulse count set latency correctly
+Preconditions    - LLRF receives triggers. All changed gate settings are RESTORED after the scan.
