Query Response

The STDEV command calculates the standard deviation of the trace amplitude, in measurement units.

STDEV must be used as either a query or as a source in another analyzer-command function. Form a query by ending the STDEV statement with a question mark (?). When used as a query, STDEV queries the standard deviation to the computer. Use STDEV as a source by incorporating the STDEV statement into the source of any spectrum-analyzer command having prede￿ned function in its syntax diagram. When STDEV is used as a source, the standard deviation is used for operation by the command that contains

STDEV.
