Trace:data? - Keithley 6430 Instruction Manual

C-4 Data Flow

TRACe:DATA?

If the data store is enabled, Sample Buffer data, CALC1 results, and CALC2 readings
become available to the TRACE block for storage. The selected feed determines which group
of readings are stored.
The TRACe:DATA? command reads the entire contents of the data store.
CALCulate3:DATA?
Statistical information (minimum, maximum, mean, standard deviation, and peak-to-peak)
is available for measure readings stored in the buffer. If the readings in the data store came
directly from the Sample Buffer, then the selected statistic calculation will be performed on all
enabled measurement functions. The calculation results are returned in the following fixed
order:
VOLTage result, CURRent result, RESistance result
When the TRACE buffer is feeding off CALC1 or CALC2, the selected statistic calculation
is performed on the selected feed. Thus, a single statistic result is acquired for each reading
stored in the data store.
The CALCulate3:DATA? command acquires the results of the selected calculation.
