Execution time
Displays the analysis and dealing time of long form command.
However for commands with parameter data, the time is that for the case
determined by the data format specified by the data item, and for queries the
time is that with headers enabled.
･ In the 3332, there may be a maximum delay of 100 ms relating to internal
processing from the time that a command is received until command analysis
starts.
･ If when the internal processing time has elapsed the command analysis is not
yet completed, the display update is delayed.
･ All commands are sequential.
･ Communications with the controller require the data transmission time to be
added. The GP-IB transmission time depends on the controller.
RS-232C: when the data length is start bit is 1, set to 8, parity is none, stop
bit is 1 (total number of the data is 10).
9600 bit/second 960 character/second
4800 bit/second 480 character/second
2400 bit/second 240 character/second
1200 bit/second 120 character/second
･ For setting commands, allow a pause after changing a setting to allow
measurement to stabilize.
・The analysis time for the "MEAS?" command varies depending on the
number of data specification items. When there are two or more data items,
the amount of analysis time can be minimized by specifying each item in
"DATA:ITEM" format.
