3.10 Gates
The EPOCH 650 features two standard independent measurement gates and one
optional independent measurement gate. Gate 1 and gate 2 are the standard
measurement gates. The Interface Gate is an optional measurement gate principally
used in immersion applications (see “Interface Gate” on page 271).
Gate 1 is displayed as a red, solid horizontal bar. Gate 2 is displayed as a blue, hollow
horizontal bar. The Interface Gate is displayed as a yellow, hollow horizontal bar.
These gates independently define digital measurements regions for amplitude, time-
of-flight measurements, and other specialized readings. Each gate also features alarm
and zoom functions.
3.10.1
Quickly Adjusting Basic Gate Parameters
The GATES direct-access key allows instant access to gate start, width, and level
adjustments without requiring the user to enter any gate-related menus. This is the
most common method for gate adjustments.
When GATES is pressed, the box above the first menu displays the gate 1 start
position (see Figure 3-9 on page 58). Once a gate is selected, the knob or arrows can
increase or decrease this value, in coarse or fine increments.
Figure 3-9 The Gate 1 start position adjustment
Pressing GATES repeatedly scrolls through the start, width, and level setting of every
active gate. Pressing
or NEXT returns focus to the menu group used before gate
adjustment, allowing efficient adjustment of the gates with minimal interference for
the operator.
For more comprehensive gate setup and adjustment, there are three menus that
manage gate settings:
Gate1

Gate2
, and
