[SENSe<[1]..4>][:POWer]:BURSt:DTOLerance <tolerance>
The end of a burst (power pulse) is recognized when the signal level drops below the
trigger level. Especially with modulated signals, this may also happen for a short time
within a burst. To prevent the supposed end of the burst from being recognized too early
or incorrectly at these positions, a time interval can be defined via
SENS<[1]..4>:BURS:DTOL
(drop-out tolerance) in which the pulse end is only recog-
nized if the signal level no longer exceeds the trigger level. This is shown in the figure
below: The drop-out time, i.e. the time in which the signal remains below the trigger level,
is shorter than the drop-out tolerance. The burst end is thus recognized correctly.

Parameters:

Default unit: S
[SENSe<[1]..4>][:POWer]:TGATe<[1]..4>[:EXCLude]:MID:OFFSet[:TIME] <time
interval>
Together with
SENS:TGAT:MID:TIME
, allows a time interval in a timegate to be blanked
out.
SENS:TGAT:MID:OFFS:TIME
determines the distance from the start of the mea-
surement to the start of the interval to be blanked out (see
​
figure 6-11
​
MID parameter in
the Timegate mode ).
Parameters:
<time interval> float_value
Range:
depending on sensor
*RST: depending on sensor
Default unit: S
