Parameters

<cnum>

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

Applicable Models: N522xB, N523xB, N524xB, M937xA, P937xA

(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.

<num>

Data point (bucket) number. Choose any data point between: 0 and the number of data points minus 1.

Examples

CALC:MARK:BUCK 5

calculate2:marker2:bucket 200

Query Syntax

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

Return Type

Integer

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.

Applicable Models: N522xB, N523xB, N524xB, M937xA, P937xA

(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.

Applicable Models: N522xB, N523xB, N524xB, M937xA, P937xA

(Read-only) Reads the marker's Y-axis value. The format of the value depends on the current CALC:MARKER:FORMAT setting. If the marker is set as delta, the data is relative to the reference marker. The query always returns two numbers:
