The Sync AFC Speed sets the ability of the loop to follow changes in the
external reference signal. “Fast” can track signals with more line rate variation.
“Slow” has lower jitter.
Applies a voltage to the signal to keep one point on the waveform at a fixed DC
level. This makes taking measurements easier when the DC level of the
waveform shifts due to changes in signal content. Setting choices are Fast, Slow,
and Off.
H
Select
Off
when you wish to see the DC offset in the signal. Off cancels the
operation of the DC Restore circuitry.
H
Select
Slow
when you wish to remove DC offset from the signal but you still
want to see hum.
H
Select
Fast
when you want to remove the effects of hum and offset from the
signal.
The NTSC Setup setting optimizes the operation of the WVR610A &
WVR611A for NTSC signals with and without set up. For example, this setting
changes the scaling of the vector bar targets.
When V+ is chosen, the phase reference of the --V lines is inverted, then shown
as an overlay on the +V lines to provide a comparison display.
External Reference Setting
The External Reference setting specifies the allowed formats of the signal on the
EXT REF IN connector. See Table 2--18.
