WB PSD Noise
WB PSD Noise
The wideband power spectral density (PSD) noise test measures the noise
energy at a point in a noise spectrum. It is expressed as power per hertz at
a point in a noise spectrum.
PSD
The PSD page allows you to configure the parameters
for the wideband PSD noise test and view the results
in either Portrait or Landscape Mode.
Current Group is the current test group name, for
example Noise Tests.
Current Test displays the test being measured.
Here you can switch to another test from the given
list. However, this action will terminate the
ongoing measurement test.
Bandwidth allows you to select the frequency
range for the test from a list of available
bandwidths: ISDN, HDSL, SHDSL, ADSL1/2, ADSL2+, VDSL2-8,
VDSL2-12, VDSL2-17, VDSL2-30, or VDSL2-35.
Noise Filter defines the filter currently enabled. Options are: None,
ISDN-E, HDSL-F, ADSL-G, ADSL, ADSL2+, VDSL, VDSL2-8, VDSL2-12,
VDSL2-17, VDSL2-30, VDSL2-35.
Termination is one of the following:
Ter minated if the termination resistance is internal to the unit.
Bridging if additional termination resistance is used to bridge onto
live circuits with minimal interruption.
HiZ Cable when using this cable to connect to T1/A1-R1/B1
(Yellow - Blue) connectors. When selected, the Termination
Resistance automatically sets to100
Ω.
