To select the grid type
When the
Video
trigger type is selected (see "Video Trigger" on page 187),
and the vertical scaling of at least one displayed channel is 140 mV/div,
the
Grid softkey lets you select from these grid types:
• Full — the normal oscilloscope grid.
• mV — shows vertical grids, labeled on the left, from - 0.3 V to 0.8 V.
•
IRE
— (Institute of Radio Engineers) shows vertical grids in IRE units,
labeled on the left, from - 40 to 100 IRE. The 0.35 V and 0.7 V levels
from the
mV grid are also shown and labeled at the right. When the IRE
grid is selected, cursor values are also shown in IRE units. (Cursor
values via the remote interface are not in IRE units.)
The mV and IRE grid values are accurate (and match Y cursor values)
when the vertical scaling is 140 mV/division and the vertical offset is
245 mV.
To select the grid type:
1 Press [Display] (or [Display] > More on 1 Ghz and 1.5 GHz bandwidth
models).
2 Press the Grid softkey; then, turn the Entry knob to select the grid
type.
