ndigo bool t tdc enabled
Enable capturing of TDC measurements on external digital input channel.
ndigo bool t tdc fb enabled
Enable enhanced TDC resolution. Currently not implemented.
double analog offset[NDIGO CHANNEL COUNT]
Sets the input DC offset-values to +- this value in volts. Defaults to 0.
double dc offset[2]
Sets the DC offset in volts for the TDC trigger input (index 1) and the GATE input (index 0).
The trigger threshold is zero. For negative 0.8V NIM pulses a value of 0.4 should be set here.
ndigo trigger trigger[NDIGO TRIGGER COUNT + NDIGO ADD TRIGGER COUNT]
Configuration of the external trigger sources. Threshold is ignored for entries 8 and above.
The trigger indexes refer to the entry in the trigger array and are defined like this:
#define NDIGO TRIGGER A0 0
#define NDIGO TRIGGER A1 1
#define NDIGO TRIGGER B0 2
#define NDIGO TRIGGER B1 3
#define NDIGO TRIGGER C0 4
#define NDIGO TRIGGER C1 5
#define NDIGO TRIGGER D0 6
#define NDIGO TRIGGER D1 7
#define NDIGO TRIGGER TDC 8
#define NDIGO TRIGGER GATE 9
#define NDIGO TRIGGER BUS0 10
#define NDIGO TRIGGER BUS1 11
#define NDIGO TRIGGER BUS2 12
#define NDIGO TRIGGER BUS3 13
#define NDIGO TRIGGER AUTO 14
#define NDIGO TRIGGER ONE 15
Always positive edge-sensitive sources:
#define NDIGO TRIGGER TDC PE 16
#define NDIGO TRIGGER GATE PE 17
#define NDIGO TRIGGER BUS0 PE 18
#define NDIGO TRIGGER BUS1 PE 19
#define NDIGO TRIGGER BUS2 PE 20
#define NDIGO TRIGGER BUS3 PE 21
ndigo trigger block trigger block[NDIGO CHANNEL COUNT + 1]
A structure describing the trigger settings of the four channels plus the timestamp channel. In
some modes not all channels are used.
ndigo gating block gating block[4]
A structure describing the gating blocks that can be used by the trigger blocks to filter triggers.
ndigo extension block extension block[NDIGO EXTENSION COUNT]
A structure describing the routing of the 4 digital channels of the Ndigo extension board to the
trigger matrix.
