Horiz-Vert Softkey
The horiz-vert softkey is used to select and enter the horizontal and
vertical tolerance parameters. The horizontal parameter defines the
maximum signal excursion right and left of the selected source. The vertical
parameter defines the maximum signal excursion above and below the
selected source.
The maximum signal excursion is equal in both directions from the selected
source, except when the source is channel and the display mode is envelope.
In that case, the upper and lower limit masks are generated as follows:
e If the vertical and horizontal tolerances are set to zero, then the lower limit
mask is the minimum envelope waveform and the upper limit mask is the
maximum envelope waveform.
e [f vertical and horizontal tolerances are set to any value other than zero,
then the lower limit mask is the minimum envelope waveform with the
specified tolerance applied, and the upper limit mask is the maximum
envelope waveform with the specified tolerance applied.
You can enter the tolerance either in divisions or in volts and seconds,
depending on the current selection of the tolerance units softkey.
When units are divisions, horizontal entries of from 0.000 to 1.000 are
allowed, and vertical entries of from 0.000 to 8.000 are allowed.
When units are volts-time, horizontal entries are limited to the current time
base setting. Entries from 0.00000 to 200.0000 seconds are allowed.
However, if the entered value exceeds the current time base value
(time/division), it is automatically adjusted to the maximum value allowed.
Vertical entries are limited to the currently selected source’s vertical setting.
Entries from 0.00000 to 40.0000 volts are alowed. However, if entered value
exceeds eight times the vertical volts/division value for the source selected, it
is automatically adjusted to the maximum value allowed.
