To Set Zoom Offset:
Setting Zoom Interval
You can zoom into one or more of the eight slots in a channel using a combination of
this Zoom Interval and the Zoom Offset. If you decide to zoom in on a portion of the
channel, that is, you zoom in on fewer than the eight slots available, you use this
Zoom Interval setting to determine how many of the eight slots are displayed.
The possible values you can set for Zoom Interval depend on your Zoom setting. If
Zoom is set to Slots, that is, you want to display one or more slots or partial slots,
you can set Zoom Interval to any value between 0.25 and 8.0 using 0.25 increments.
If your Zoom setting is Rise/Fall, this key is not available because the Rise/Fall
display is focussed on one particular slot only.
Your Zoom Offset is limited by this Zoom Interval setting. With eight slots in any
one channel, your Zoom Offset and your Zoom Interval settings can not total any
more than eight slots. If you enter a Zoom Interval figure here that, when added to
the Zoom Offset setting, totals more than eight, your Zoom Offset setting will be
reduced so that Zoom Offset + Zoom Interval = 8.
This Zoom Interval setting is only available if View is set to Power versus Time and
if Zoom is set to Slots.
NOTE It is this Zoom Interval setting here that can have an effect on your Zoom Offset
setting. Your Zoom Offset setting is limited by your setting of Zoom Interval.
NOTE The first of the eight slots in a channel is always referred to as Slot 0, and the final
slot in the channel is Slot 7.
