1. Detector has slow module, for example high voltage module, and ADCYou could do it in a similar way as Nr2, if you get any bit or something if the slow HV has reached its set value
digitizer module.
So I have two records (as minimum). SCAN field of ADC record is "I/O
Intr". Situation is next. Operator changes voltage setting record of High
Voltage module. ADC should wait until potential will be set. How can I do it?
2. Detector has amplifier with gain and ADC digitizer module.|--ai--------| |ADC-Module | |------------| |--bo---------| |SCAN=IO/Intr| |pulse | |FLNK |--->-|-------------|--->----- |INP=hardware| |HIGH=.1second| | |------------| | | | |-------------| | SetGainHere | | |--calcout------------------| | | |SetGainModule | | | |---------------------------| | | |INPA |CPP<| | |CALC=A | |>-|B | |OCAL=B | |OOPT=Transition to Non-zero| |DOPT=Use OCAL | |--ao--------|
So I have two records (as minimum). SCAN field of ADC record is "I/O
Intr". Situation is next. Operator can change gain during ADC is doing
measurement (for example, ADC should take 200 samples, gain was changed on 100 samples). How can I
"freeze" gain?
Also I can find Record Reference Manual for Epics 3.13.7. Is there more new manual?
Thanks, Andrei.
