Used for measurement of NTSC monitors
Used for measurement of PAL and SECAM
monitors
Used to synchronize measurement with the
monitor’s vertical synchronizing signal (fre-
quency: 40 to 200 Hz) that is input to the
instrument. (For how to input the vertical syn-
chronizing signal, refer to page 28.)
Used for measurement of any monitors, for
instance, when the frequency of monitor’s ver-
tical synchronizing signal is unknown or when
the vertical synchronizing signal cannot be in-
put into the instrument for some reason.
If the frequency of the monitor’s vertical syn-
chronizing signal is known, set it to be used
for measurement.
