53220A/53230A Input Signal Conditioning 4
Threshold Slope
The slope (edge) of the input signal on which the threshold level occurs is
specified with the command:
INPut[{1|2}]:SLOPe[{1|2}] {POSitive|NEGative}
INPut[{1|2}]:SLOPe{1|2}]?
(query form)
POSitive
- the trigger point occurs on the positive (rising) edge. The reset
point occurs on the negative (falling) edge (Figure 4-4).
NEGative
- the trigger point occurs on the negative edge, with the reset point
occurring on the positive edge.
The slope setting does not apply to pulse width, duty cycle, or rise/fall time
measurements (i.e. measurements with pre-defined slopes).
For single-channel time interval measurements,
SLOPe
/
SLOPe1
sets the edge
for the start event and
SLOPe2
sets the edge for the stop event.
CONFigure
and
MEASure
do not change the slope setting. Following a reset
(
*RST
) or instrument preset (
Preset
), the positive (rising) slope is selected.
