Test List 2
The Test List 2 tab allows you to select
additional tests to include in the auto
test function.
The following additional tests are
available:
³
VF Receive Tone measures the
level and frequency of the
incoming voice signal.
³
WB Receive Tone measures the level and frequency of the incoming
wideband signal.
Note: The VF and WB Receive Tone tests are mutually exclusive. When one test is
enabled, the other is automatically disabled.
³
WB Longitudinal Balance verifies that the wideband longitudinal
balance ratios comply with applicable standards.
³
PSD Noise measures power spectral density noise.
³
Attenuation measures the amount of reduction in signal strength.
³
WB Impulse Noise measures the irregular occurrences of energy
spikes in the wideband range that have random amplitude and
spectral content.
³
TDR test identifies and locates all types of faults as well as bridge taps
(multiple appearances) and load coils.
To select tests:
1. Press the up/down arrow keys to highlight a desired test.
2. Press to toggle between Enable and Disable.
