Gates and Gate Windows
A “gate” is a way of artificially restricting the
minimum or maximum range of the instrument.
When you use the gating feature, the UltraLyte
detects no targets nearer than the “short gate”
setting or farther than the “long gate” setting. The
range within which a target can be detected is called
the “gate window.”
Short gate
Long gate
The Ultra Lyte detects
only those targets that
are within this range
gate window
Gating is useful when you must restrict your speed
detection operations to a particular area, or during a
survey in which partial obstructions present a danger
of giving false readings.
Gate Window Characteristics
The gate window you can set has the following
characteristics:
•
If you set only the short gate and leave the long
gate null, the gate window extends from the
short gate value to the maximum range of the
instrument.
•
If you set only the long gate and leave the short
gate null, the gate window extends from the
minimum range of the instrument to the long
gate value. (The minimum range is zero in
survey mode, 50 feet (15 m) in speed mode).
