Frequency Tests
246 MAX-635G
RX Tone with FED
RX Tone with FED
The RX Tone with FED test can be setup to run a single frequency or run
sequentially through a selected number of frequencies. The Teletech TS125
or Viavi UFED IIB Remote FED (far end device) is used and FED software
option must be enabled on your unit. However the test is not dependent on
enabling the FED in FED Setup.
Single Tone
The Single Tone tab allows you to configure the
following parameters:
Current Group is the current test group name, for
example Frequency Tests.
Current Test displays the test being measured.
Here you can switch to another Frequency test
from the given list. However, this action will
terminate the ongoing measurement test.
Receive Tone allows you to select either a VF
(voice frequency) or WB (wideband) signal. WB
selection is only available when the 30 MHz
Wideband Testing software option is installed.
Termination Resistance defines how much resistance the tester uses
to connect to the line, and is set as follows:
for VF Tone, a read-only value of 600 Ω.
for WB Tone, select 100, 120, or 135 Ω.
FED Frequency sets the frequency that the TS125 FED will transmit
and is a value in Hz for VF Receive Tone (default 300 Hz) and kHz for
WB (default 196 kHz).
Tone Duration modifies the duration value of the tone from
5 - 60 seconds. Default is 5s.
