CALCulate<n>:MARKer<m>:FUNCtion:NDBDown
<Distance>
This command defines the distance of the n dB down markers to the reference marker.
The temporary markers T1 and T2 are positioned n dB below the active reference
marker. The frequency and time position of these markers can be queried with
CALCulate<n>:MARKer<m>:FUNCtion:NDBDown:FREQuency?
and
CALCulate<n>:MARKer<m>:FUNCtion:NDBDown:TIME?
. The bandwidth between
the markers can be queried with
CALCulate<n>:MARKer<m>:FUNCtion:NDBDown:
.
Suffix:
<n>
.
Selects the measurement window.
<m>
irrelevant
Parameters:
<Distance>
Distance of the temporary markers to the reference marker in
dB.
*RST:
6dB
Example:
CALC:MARK:FUNC:NDBD 3dB
Sets the level spacing to 3 dB.
Manual operation:
See
CALCulate<n>:MARKer<m>:FUNCtion:NDBDown:FREQuency?
This command queries the position of the n dB down markers on the x-axis when mea-
suring in the frequency domain.
To get a valid result, you have to perform a complete measurement with synchroniza-
tion to the end of the measurement before reading out the result. This is only possible
for single sweeps.
Suffix:
<n>
.
Selects the measurement window.
<m>

Return values:
<Frequency>
<frequency 1>
absolute frequency of the n dB marker to the left of the reference
marker in Hz
