h1. VLD EPICS development h2. Run the IOC * log into hccoda@nps-vme4 from a terminal <pre> ssh hccoda@nps-vme4 </pre> * execute startup script (located in $HOME/bin) <pre> startIOC </pre> h2. Calibration test script Enable / disable the random pulser to the connector and channels defined in the script. * log into hccoda@cdaql3 from a terminal <pre> ssh hccoda@cdaql3 </pre> * execute calibration test script <pre> cd $HOME/scripts/VLD ./vld_calibration_test [0,1] </pre> > * Usage <pre> vld_calibration_test.sh [0,1] 0: disable 1: enable </pre> > * Script variable description > > * *VLDSLOT* > > > IOC Base name + VLD Slot number. This is defined by the IOC startup script. Currently vme4 for nps-vme4, and VLD17 Slot17 for the VLD in that crate. > > * *PULSER_SETTING* > > > Enum for random pulser setting <pre> 0: 700kHz 1: 350kHz 2: 175kHz 3: 87.5kHz ... 7: 5.5kHz ... 15: 21 Hz </pre> > > * *TRIG_SOURCE* > > > Source to trigger pulser <pre> 0: always high (should be Periodic trigger), 1: random trigger only 2: FP_trigger </pre> > > * *C0_LOW_MASK*, *C0_HIGH_MASK*, *C1_LOW_MASK*, *C1_HIGH_MASK*, etc.. > > > Connector channel enable bitmasks. E.g. to enable connection 0's channel 0 and 1, <pre> C0_LOW_MASK=0x3 </pre> h2. Square wave pulse script Set the pulse waveform to a square wave with specified width and amplitude * log into hccoda@cdaql3 from a terminal <pre> ssh hccoda@cdaql3 </pre> * execute square wave pulse script <pre> cd $HOME/scripts/VLD ./vld_square_pulse.sh [width] [amplitude] </pre> > * Usage <pre> vld_square_pulse.sh [width] [amplitude] width: steps of 2ns [0, 1000] amplitude: DAC setpoint at each step [0, 63] </pre>
