VSIZ Vertical SIZe
Classification: Format parameter setting
Command Syntax: VSIZ
Limits: = positive value (floating point accepted)
Query Syntax: VSIZ?
Query Response:
Description: The VSIZ command establishes the vertical physical size of the
image on the display. Units expected (or returned) vary according
to the last mode set with USIZ command. The VSIZ command
is context sensitive and must appear between begin and end
commands: FMTB and FMTE. The VSIZ? query returns the current
setting of VSIZ.
Note – Make sure that the USIZ parameter is properly set before
using the VSIZ command. Changing the USIZ setting after
entering VSIZ 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
VSIZ. The ALLU command updates hardware to the new setting
and redraws the test image, taking the new size into account.
