MATH selects th
e math waveform as the source for the histogram.
REF<1–4> selects a reference waveform as the source for the histogram. The x
variable can b
e expressed as an integer ranging from 1 through 4.
Examples
HISTOGRAM:SOURCE CH1 enables the Channel 1 waveform to be compared
against the histogram box.
HISTOGRAM:SOURCE? might return :HISTOGRAM:SOURCE CH1, indicating that
the waveform for Channel 1 is the source for the histogram.
HIStogram:STARt? (Query Only)
Returns the time (horizontal) or vertical units value (vertical) of the first bin wher
e
the histogram data starts. The HIStogram:MODe must be either
HORizontal
or VERTical for a value to be returned. If the mode is OFF, an error event is set
and nothing is returned.
If the HIStogram:MODe is
HORizontal, the value returned is the time of the left
bin. If the HIStogram:MODe is
VERTical the value returned is the vertical units
value of the top bin. The returned value is an <NR3>.

HIStogram:MODe
Returns
<NR3> showing the returned value.
Examples
HISTOGRAM:START? might return :HISTOGRAM:START 2.0000E-06
indicating that the first bin is at 2 μs.

HORizontal:DELay:MODe
This command specifies the horizontal delay mode.

HORizontal:DELay:MODe?
Related Commands
HORizontal:POSition
Arguments
OFF sets the Horizontal Delay Mode to off. This causes the HORizontal:POSition
command to operate like the HORIZONTAL POSITION knob on the front panel.
ON sets the Horizontal Delay Mode to on. This causes the
HORizontal:DELay:TIMe command to operate like the HORIZONTAL
POSITION knob on the front panel.
<NR1> = 0 sets the Horizontal Delay Mode to off; any other value sets this mode
to on.
Examples
HORIZONTAL:DELAY:MODE OFF sets the Horizontal Delay Mode to off, allowing
the horizontal position command to operate like the HORIZONTAL POSITION
knob on the front panel.
HORIZONTAL:DELAY:MODE? might return HORIZO NTAL:DELAY:MODE OFF
indicating that the Horizontal Delay Mode is off and that the horizontal position
command operates like the HORIZONTAL POSITION knob on the front panel.
HORizontal:DELay:TIMe
This command specifies the horizontal delay time (position) that is used when
delay is on (the default mode).
