HORizontal:POSition
This command specifies the horizontal position, in percent, that is used when
delay if off. If Horizontal Delay Mode is turned off, this command is equivalent
to adjusting the HORIZONTAL POSITION knob on the front panel. When
Horizontal Delay Mode is on, this command stores a new horizontal position that
is used when Horizontal Delay Mode is turned off.

HORizontal:POSition?
Related Commands
HORizontal:DELay:TIMe
Arguments
<NR3> is a floating point number that specifies the horizontal position expressed
as the percentage of the waveform acquired before the trigger.
Examples
HORIZONTAL:POSITION 50 sets the horizontal position to 50%.
HORIZONTAL:POSITION? might return :HORIZONTAL:POSITION 100
indicating that the horizontal position is set to 100%.
HORizontal:PREViewstate? (Query Only)
Returns a boolean value to indicate whether the display system is in the preview
state.

Returns
<NR1> = 1 if the d
isplay system is in the preview state.
<NR1> = 0 if the display system is not in the preview state.
HORizontal:RECOrdlength
Sets the horizontal record length. The query form of this command returns the
current horizontal record length.
Group
Horizontal
Syntax
HORizontal:RECOrdlength <NR1>
HORizontal:RECOrdlength?
Arguments
<NR1> represents the horizontal record length value.
NOTE. The supported horizontal record length values for models MSO4104B–L,
MSO4102B-L, DPO4104B-L, and DPO4102B-L are 1,000, 10,000, 100,000,
1M and 5M. The supported record length values for all other models are 1,000,
10,000, 100,000, 1M, 5M, 10M and 20M, with the exception of MDO3000, which
does not support 20M record length.
Examples
HORIZONTAL:RECORDLENGTH 10000 specifies that 10000 data points will be
acquired for each record.
HORIZONTAL:RECORDLENGTH? might return : HORIZONTAL:RECOrdlength
1000
indicating that the horizontal record length is equal to 1000 data points.
HORizontal:SAMPLERate? (Query Only)
The command form is ignored. The query returns the sample rate for analog
channels in samples per second.
Group
Horizontal
Syntax
HORizontal:SAMPLERate?
Examples
:HORIZ
ontal:SAMPLERate? might return 5.0000E+9 indicating that the current
sample rate for analog channels is 5G samples per second.
