HEADer|:HDR
This command specifies the Response Header Enable State that causes the
oscilloscope to either include or omit headers on query responses.
NOTE. This command does not affect IEEE Std 488.2-1987 Common Commands
(those starting with an asterisk); these commands never return headers. This
command does affect the Response Header Enable State of both the USBTMC and
VX
I-11 interfaces. Refer to the Introduction for additional information.
NOTE. Refer to the Waveform Transfer Command Group text for more
c
omprehensive information.

Arguments
OFF sets the Res
ponse Header Enable State to false. This causes the oscilloscope
to omit headers on query responses, so that only the argument is returned.
ON sets the Res
ponse Header Enable State to true. This causes the oscilloscope
to include headers on applicable query responses. You can then use the query
response as a command.
<NR1> = 0 sets the Response Header Enable State to false; any other value sets
this state to true.
Examples
HEADER|:HDR OFF specifies that the oscilloscope omits headers on query
responses, so that only the argument is returned.
HEADER|:HDR? might return :HEADER 1 indicating that the oscilloscope is
including headers on applicable query responses.
HIStogram? (Query Only)
This query-only query returns all histogram parameters; it queries the state of
all histogram parameters that the user can set. This command is equivalent to
selecting Waveform Histograms from the Measure menu.

Arguments
<NR3> is a floating point number that specifies the left position of the histogram
box in source waveform horizontal units.
<NR3> specifies the top position of the histogram box in source waveform vertical
units.
<NR3> specifies the right position of the histogram box in source waveform
horizontal units.
<NR3> specifies the bottom position of the histogram box in source waveform
vertical units.
Examples
HISTOGRAM:BOX 1E-9, 0.2 50, 2E-9, 0.500 defines the coordinates of the
histogram box in source waveform coordinates.
HISTOGRAM:BOX? might return :HISTOGRA M:BOX 1.0000E-09, 0.2500,
2.0000E-09, 0.5000
, which identifies the coordinates of the histogram box in
source waveform coordinates.
HIStogram:BOXPcnt
This command specifies the histogram box coordinates in terms of percentages
of the full screen extents of the source waveform. The arguments refer to the
left (percent of the horizontal screen extent), top (percent of the vertical screen
extent), right (percent of the horizontal screen extent), bottom (percentofthe
vertical screen extent). The valid range for these values is 0.0 to 100.0.
