[Dsg-hallb_magnets] Changing Torus Fast-Daq IDCCT1 signal?

[Tyler Lemon]

Hello Ruben, 

I have been monitoring the Torus Live Fast-Daq EPICS screen in preparation for testing the digital filters and have noticed odd signals in IDCCT1. 

IDCCT1 Fast-Daq signal is changing in amplitude as I monitor it. So far I have seen it steady at several amplitudes including 4 [A], 0.025 [A], and 1 [A]. Attached are screen shots of the EPICS Fast-Daq Live screen showing these signals and also a screen shot of the signal in transition from one amplitude to another. 

01 Torus Fast-Daq IDCCT1- large 4 A amplitude signal- 2017-01-18 at 933AM -- shows 4 [A] amplitude signal seen at 9:33AM. 
02 Torus Fast-Daq IDCCT- transition to small amplitude- 2017-01-18 933AM-- shows transition from 4 [A] amplitude to 0.025 [A] amplitude. 
03 Torus Fast-Daq IDCCT1- 0.025 A amplitude signal- 2017-01-18 at 934AM -- shows 0.025 [A] amplitude signal seen at 9:35AM 
04 Torus Fast-Daq IDCCT1- 1 A amplitude signal- 2017-01-18 at 950AM -- shows 1 [A] amplitude signal seen at 9:50AM. 

Is there any work occurring on the Torus system that would affect the IDCCT1 signal or Fast-Daq signals? If so, should I hold off on any testing of the digital filters until the work is done? 

Best regards, 
Tyler
