Operating Basics
9. (Option VGA) The specified
polarities for the H Sync and V
Sync signals vary between the
timing standards. In the absence
of the MIU and with Auto Detect
selected, the VM5000 will
prompt you to connect the H
and V Sync signals to determine
the polarities. If you use
the MIU, the VM5000 will automatically
determine the H and
V Sync polarities.
Once the sync signal polarities
are determined, the measurement
cycle begins. This “polarity
test” is performed at the beginning
of every measurement
cycle. To prevent this test from
running at the beginning of every
measurement cycle, take
any measurement once with
Auto Detect selected. Once a
measurement cycle has been
completed with Auto Detect
selected, you can deselect
Auto Detect. The VM5000 remembers
the polarity of the
sync signals. Any time you
change the format set-up for the
device-under-test, you should
complete a measurement with
Auto Detect selected.
