Characteristic Suppl emental InformationPerformanceRequirement
Center Measure When activated, the signal nearest
center screen (or nearest marker if
marker is on) and above a preset
threshold level, is moved to center
screen
The frequency and amplitude values are
preceded by the letter C
Readout Resolution 1 kHz or 1 Hz Readout resolution is sel ectable
Signal Tracking When activated, the centered signal is
held at center screen
Signal tracking requires a signal strength
greater than the threshold level
If the strength of a signal being tracked
decreases below the threshold level, the
instrument displays the message NO
SIGNAL FOUND ABOVE THRESHOLD
