CALCulate
To determine if a filter was applied to the measurement data, send CALC:MARK:FUNC WEIGht. Send
the CALC:MARK:FUNC:RES? query to determine the results. The query returns 1 if the A-weight filter
was applied to the measurement data; 2 if the B-weight filter was applied and 3 if the C-weight filter was
applied. If a filter was not applied, the query returns 0 (false). The query returns 4 if the value is
undefined. For example, if you are using two data registers, one which used the A- weight filter and the
other which used the B-weight filter, the value is undefined.
To determine the Z-axis value for the measurement, send CALC:MARK:FUNC SINFo. Send the
CALC:MARK:FUNC:RES? query to determine the Z-axis value for the measurement data. The Z-axis
value indicates where the measurement data was extracted from a waterfall. It tells you when the
measurement data was armed.
