TimingScan GUI

The TrimingScan? gui allows you to scan in TX coarse delay from any number up to 31. You can define the minimum number of triggers per delay bin. The gui inserts the current TX delay in the trigger word (TIM register offset 0x16, bits 0 to 7) and also maintains a table of TX delay vs trigger count, min L1ID and max L1ID.

The gui can scan manually (the gui manually scans TX coarse delay for each module) or in rod histogramming mode (the scan is performed by the SctApi and a TestData object is published similar to Alans TimingScan? beanshell script).

Running the gui

Start a run,then:

TimingScan startDelay endDelay binSize <rod histogramming option>

eg
TimingScan 0 31 3 
- starts timing scan from 0 to 31 with binsize 3 with rod histigramming

TimingScan 0 31 3 -norod 
- starts timing scan as above with no rod histogramming

The source code is in $SCT_DAQ_ROOT/sctGUI/sctutils/TimingScan?.java
