OptoFidelity Video Multimeter
– User Manual
Once the test application shows
completely white content
, the measurement is
started with
Start
button. During the measurement, the label of the push button is
updated as
Stop
(see Figure 30). When the device under test is moving and the
measurement produces data, the application updates the latency graph and the
following data fields:
•
M2P
: The measured motion-to-photon latency between the movement of the
device and the updates of the display content (in milliseconds). Most recent
value (now), min, avg and max values are displayed. The estimated accuracy
of the latency measurement (in +/-milliseconds, after the most recent value
(now))
•
FPS
: The measured frame intervals (in milliseconds) of the displayed content
are displayed. The values include most recent measured value (now), min, avg
and max.

When the measurement is stopped,
during the white content
(see Figure 31), the
label of the Start/Stop push button is updated as
Start
again. The
Save
button is also
enabled. The data fields and the latency graph show the results in the end of the
measurement.
