ALARM THRESHOLDALARM THRESHOLD

ALARM THRESHOLD

This is the leakage measurement level at which the alarm will occur.

ALARM MUTE TIME-OUTALARM MUTE TIME-OUT

ALARM MUTE TIME-OUT

When performing leakage measurements, you can mute the audible

alarm by pressing the key. This setting determines the amount

of time that will elapse before the alarm is reactivated.

LEAKAGE UNITSLEAKAGE UNITS

LEAKAGE UNITS

This determines the units in which leakage is measured and the alarm

threshold is set. You can select between; µV/m, dBµV/m, dBmV,

dBµV, µV, dBm and dB20µV.

MEASUREMENT FREQUENCYMEASUREMENT FREQUENCY

MEASUREMENT FREQUENCY

Enter the frequency of the carrier that you want to monitor for RF

leakage. You can select from 115 to 140 MHz.

MEASUREMENT CARRIER TYPEMEASUREMENT CARRIER TYPE

MEASUREMENT CARRIER TYPE

For accurate measurements, be sure to select the type of carrier that

you will be measuring leakage on — either Carrier Wave (CW) or

video.

DISTANCE UNITSDISTANCE UNITS

DISTANCE UNITS

Select the units in which you want distance values to be displayed and

entered. You can select between feet or meters.

TAG MODULATION FREQUENCYTAG MODULATION FREQUENCY

TAG MODULATION FREQUENCY

Enter the modulation frequency to detect when searching for a tag.

This should match the setting of the LT1000 Leakage Tagger that

you are using. It is recommended that the tag modulation frequency

be adjusted to a minimum of 20 Hz. By maintaining the 20 Hz tag

criteria, false tags will be reduced while still preserving the video

quality of the tagged carrier. You can select a Tag Modulation

frequency from 3 to 25 Hz.
