HORizontal:D
IGital:SAMPLERate:MAIn? (Query Only)
Returns the sample rate of the main digital acquisition.

Syntax
HORizontal:DIGital:SAMPLERate:MAIn?
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.

HORizontal:S
CAle
This command specifies the time base horizontal scale.
Group
Horizontal
Syntax
HORizontal:SCAle <NR3>
HORizontal:SCAle?
Arguments
<NR3> is a floating point number that specifies the range from 400 ps to 1000 s,
depending on the record len
gth. The
<NR3> argunent will be coerced to the
nearest horizontal scale setting.
Examples
HORIZONTAL:SCALE 2E-6 sets the main scale to 2 µs per division.
HORIZONTAL:SCALE? might return :HORIZONTAL:SCALE 2.0000 E-06
indicating that the main scale is currently set to 2 µs per division.
ID? (Query Only)
Returns the instrument identification data. This is similar to the data returned by
the *IDN? IEEE488.2 common query, but also includes any enabled application
modules and enabled options. However, it does not include the instrument
serial number.
The format of the returned string is an extension of that specified in Tektronix
Codes and Formats with the addition of the application information (and is not
dependent upon :HEADer or :VERBose settings):
ID TEK/<model>,CF:91.1CT FV:v<firmware version> <app module info>
where:
<firmware version> is comprised of 2 numerical values separated by a decimal
point representing the major and minor version numbers, respectively.
<app module info> is a list of application modules separated by a space of
the form:
<App ID> such as DPO4EMBD:V1.00, MDO3AUTO:V1.00, etc.
