HSIZ
Horizontal SIZe
Classification:
Format parameter setting
Command Syntax:
HSIZ <physical size> (context sensitive - see FMTB and
FMTE)
Limits:
<physical size> = positive value
(floating point accepted)
Query Syntax:
HSIZ?
Query Response:
<physical size> (floating point returned)
Description:
The HSIZ command establishes the horizontal physical size of
the image on the display. Units expected (or returned) vary
according to the last mode set with USIZ command. The HSIZ
command is context sensitive and must appear between begin
and end commands: FMTB and FMTE. The HSIZ? query returns
the current setting of HSIZ.
Note – Make sure that the USIZ parameter is properly set before
using the HSIZ command. Changing the USIZ setting after
entering HSIZ will convert the size to match the new unit of
measure.
Other Required Cmds:
The units of measure must be properly set by USIZ before entering
HSIZ. The ALLU command updates hardware to the new setting
and redraws the test image, taking the new size into account.
