Remote Operation 5-92
TRIGger:CDF:COUNt
Description: Set or return the terminal count (sample population size) in millions of samples for statistical
mode acquisition. When the terminal count is reached, the CDF, CCDF or PDF is considered
―complete‖, and the instrument will halt acquisition if INITiate:CONTinuous is set to OFF. If
INITiate:CONTinuous is ON, sample acquisition will continue in the manner specified by the
TRIGger:CDF:DECImate setting.
Syntax: TRIGger:CDF:COUNt <n>
Argument: <n> = 2 to 4096 million samples
Valid Modes: Statistical mode only.
TRIGger:CDF:DECImate
Description: Set or return the decimation status when running continuously in statistical mode. This action
occurs when the terminal count is reached (as defined by TRIGger:CDF:COUNt) or the terminal
running time is reached (as defined by TRIGger:CDF:TIMe). When set to OFF, the CDF, CCDF
or PDF will clear all data and restart. If set to ON, the entire sample population will be decimated
(divided by two), and new samples will continue to accumulate into the same histogram.
Decimating has the effect of maintaining the ―shape‖ of the statistical result while slowly decaying
away the effect of past history and updating to include new events. This setting works best with
relatively small terminal counts (1 to 10 million counts) and short running times (a few seconds).
Syntax: TRIGger:CDF:DECImate <asc>
Argument: <asc> = {OFF, ON}
Valid Modes: Statistical mode only.
TRIGger:CDF:TIMe
Description: Set or return the terminal running time in seconds for statistical mode acquisition. When the
terminal time is reached, the CDF, CCDF or PDF is considered ―complete‖, and the instrument
will halt acquisition if INITiate:CONTinuous is set to OFF. If INITiate:CONTinuous is ON,
sample acquisition will continue in the manner specified by the TRIGger:CDF:DECImate
setting.
Syntax: TRIGger:CDF:TIMe <n>
Argument: <n> = 0 to 3600 seconds
Valid Modes: Statistical mode only.
