Adjusting Gain And Tcg - Cygnus 1 Ex Manual

1. The Gate Level is set to 20%
The signal is then Frozen.
2. The Gate Level is now adjusted to
71%, and the Gate Trigger point now
moves as its triggers by a later ½
cycle. The measurement value
increases to 10.0mm.
Note. You cannot adjust the Gain Values and expect to see a change in signal in
Dynamic Freeze mode, as changes to Gain require a new UT signal to be fed
through the pulser-receiver circuit.
