Critical Note: CALCulate commands act on the selected measurement. You can select one measurement for each channel using Calc:Par:MNUM or Calc:Par:Select. Learn more.

Important: Learn about programming the reference marker.


CALCulate<cnum>:MARKer:AOFF

(Write-only) Turns all markers off for selected measurement.

CALCulate<cnum>:MARKer<n>:BUCKet <num>

(Read-Write) Sets and reads the data point (bucket) number of the trace on which the marker resides. When the markers are interpolated (non-discrete), the returned value is the nearest marker bucket position.

See Critical Note

Parameters

 

<cnum>

Channel number of the measurement. There must be a selected measurement on that channel. If unspecified, <cnum> is set to 1.

<n>

Marker number to move or query. The marker must already exist. If unspecified, <n> is set to 1.

calculate2:marker2:bucket 200

Query Syntax

CALCulate<cnum>:MARKer<n>:BUCKet?

Return Type

Default

The first marker is set to the middle of the span. Subsequent markers are set to the bucket number of the previously active marker.


CALCulate<cnum>:MARKer:BWIDth <num>

(Read-Write) Turns on and sets markers 1 through 4 to calculate filter bandwidth. The <num> parameter sets the value below the maximum bandwidth peak that establishes the bandwidth of a filter. For example, if you want to determine the filter bandwidth 3 db below the bandpass peak value, set <num> to -3.

To turn off the Bandwidth markers, either turn them off individually or turn them All Off.

The analyzer screen will show either Bandwidth statistics OR Trace statistics; not both.

To search a User Range with the bandwidth search, first activate marker 1 and set the desired User Range. Then send the CALC:MARK:BWID command. The user range used with bandwidth search only applies to marker 1 searching for the max value. The other markers may fall outside the user range.

See Critical Note
