5. Read the noise on the display. Note that the reading will always
be a whole number.
7.28 Measure PAR
1. See ¶8.7 for information on this measurement.
2. A PAR waveform must be sent from the far end for this
measurement to be valid.
3. See Figure 7-5. Set switches per the SWITCH SETUP
illustration,
and set the MEASURE cursor per the bottom menu illustration
(PAR DISPLAY).
4. Read the level and PAR value on the display. Note that the
readings will always be a whole numbers.
7.29 Measure Impulse Noise
General Information
1. This is a timed test. See ¶7.24.
2. Three (3) noise thresholds are established:
low , middle , and
high . There is an equal interval between each threshold called
the
delta .
3. The time over which the run is to be made is set, called the
duration .
4. The run is started, and a running count is kept of the number of
noise pulses that exceed each threshold.
5. The run will automatically stop when the duration time is
reached, or the test can be manually stopped at any previous
time.
6. The “TIME” display resets to zero at the beginning of a run, and
keeps a running count of the time elapsed during the run.
