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.

Commands Listed in Alphabetical Order
LOCk
Enables or disables all front-panel buttons and knobs. There is no front panel
equivalent.
When the front panel is locked, neither the FPAnel:PRESS nor the FPAnel:TURN
commands will work. They will not generate an error event either. You can work
around this by using the appropriate programmatic interface commands, instead of
the front-panel commands. For example, to set the trigger level to 50%, you could
use TRIGger:A SETLevel. To force a trigger, you could use TRIGger FORCe.

Examples
LOCK ALL locks the front-panel controls.
LOCK? might return :L OCK NONE indicating that the front-panel controls are
enabled by this command.
*LRN? (Query Only)
Returns the commands that list the oscilloscope settings except for configuration
information for the calibration values, the WFMInpre? query, and the
WFMOutpre? query. This query allows you to record or "learn" the current
oscilloscope settings. You can use these commands to return the oscilloscope to
the state it was in when you made the *LRN? query. This command is identical
to the SET? Command.
