Starting xscaler (HRS) and checking raw trigger rates (updated nov 5, 2014)
Raw rates of trigger and detector channels can be accessed using a GUI. Below are the instructions for opening "xscaler" GUI
- These screens are generally already open on the agen5 machine (above the DAQ machine)
- If it is xscaler is not open then follow these instructions:
- login as a-onl on adaq1 or adaq2 machines (eg: "ssh a-onl@adaq1" )
- passwords are written on the white board
- type "goxscaler" and follow the instructions printed on the screen
- type "./xscaler Left" or "./xscaler Right" to access xscaler display

How to check the dead time
last update 12/2/14
"Needs to be updated"
There are two ways to check for deadtime:
- online using the XScaler tool.
- See above for instructions on how-to open the Xscaler.
- Select the "misc" tab.
- the ratio (DVCS_stop/DVCS_masterOR) is a measurement of the live time for our main trigger.
- offline. This solution allows to check deadtime for individual triggers (say DIS or DVCS, ...)
After you replay the run, ssh to aonl1, aonl2, aonl3 or aonl4 machine and:
