Parameters:
<Distance>
Example:
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 sweep mode.

Marker
Distance of the temporary markers to the reference marker in
dB.
For a positive offset, the markers T1 and T2 are placed below
the active reference point.
For a negative offset (for example for notch filter measure-
ments), the markers T1 and T2 are placed above the active ref-
erence point.
*RST:
Default unit: DB
CALC:MARK:FUNC:NDBD 3dB
Sets the distance to the reference marker to 3 dB.
INITiate<n>:CONTinuous
irrelevant
irrelevant
<frequency 1>
absolute frequency of the n dB marker to the left of the reference
marker in Hz
<frequency 2>
absolute frequency of the n dB marker to the right of the refer-
ence marker in Hz.
INIT:CONT OFF
Switches to single sweep mode.
CALC:MARK:FUNC:NDBD ON
Switches on the n dB down function.
INIT;*WAI
Starts a sweep and waits for the end.
CALC:MARK:FUNC:NDBD:FREQ?
This command would return, for example, 100000000,
200000000, meaning that the first marker position is at 100
MHz, the second marker position is at 200 MHz
