This command ensemble provides access to the CAEN V1729A waveform digitizer. The three subcommands allow creation configuration and introspection. See METHODS below for more information about these subcommands and their formats.
The options described in OPTIONS below allow data taking and analysis to be configured according the needs of the application.
Provides the module base address. The
must match the base address set in the rotary switches
of the module.
Threshold for internal trigger. The default value is 4095
Pretrigger time in samples. Defaults to 10240
Post trigger time in samples. Defaults to 64
-triggersourceexternal | internal | both
Specifies trigger source: his can also be 'internal', or 'both'. Defaults to external
-triggeredgerising | falling
Specifies which edge of the trigger is used. Default is rising
-triggermaskon | off
Specifies whether the trigger is masked via the EXT_EN_TRIGGER if this is 'on' EXT_EN_TRIGGER is required to enable triggers to fire. Defaults to off.
Only used if internal triggers are allowed. Set one bit for each channel from which triggers are allowed.
Sets the post trigger latency register in samples. Defaults to 4
Sets the value of the post latency pretrigger register. Defaults to 1
-samplingfreq2ghz | 1gzh | 500mhz
Sampling frequency. Default value is 2ghz
uSec to delay prior to executing the readout. this can be set to zero if the modle interrupt is used to trigger the data acquisition else it should be set to on the order of 700usec depending on triggering parameters. 650usec from end of the signal are required to transfer data. the remaining time depends on the time of the computer trigger relative to the time of the signal end. When setting this recall that the module requires 650usec to digitize and transfer data from the analog memory to the readout memory.
