Initial measurements typically occur at the ground block with the home
disconnected from the network. Prior to an installation, use Field View
measurements to verify that the system does not have a large difference
in spectrum measurements (ingress and distortion) at the node with the
current conditions at the headend. After an installation, check the noise
level again to compare the previous reading and confirm that install procedures
or components did not create new sources of ingress noise.
To configure the Field View measurement feature, select:
- Broadcast Nodes,
- All Nodes, or
- Telemetry Frequency.
To configure your meter for Field View measurement:
Node List
There are no initial configuration procedures for the Node List option.
To view nodes refer to the following steps.
Broadcast Nodes
1) From the Field View screen, press the Settings softkey, use the
arrows to select Broadcast Nodes.
2) Select ENTER to display the Broadcast Nodes screen.
The Broadcast Nodes screen provides a list of only the broadcast nodes
in the PathTrak or Phasor system.
NOTE: Only one node can be selected at any one time.
3) Once a node is selected, press the Info softkey to view the measurement
parameters associated with the selected node.
NOTE: These parameters are established by the PathTrak or Phasor system
administrator and cannot be changed locally.
All Nodes
1) From the Field View screen, press the Settings softkey, use the
arrows to select All Nodes.
2) Select ENTER to display the All Nodes screen.
The All Nodes screen provides all available nodes in the PathTrak or Phasor
system.
NOTE: If the node is active, it will be indicated by a black square.
NOTE: If the node you want to view is not displayed in Broadcast view,
contact the PathTrak or Phasor system administrator to request activation.
You must provide the PathTrak or Phasor System Administrator with the
unique identifier (UID) number of the requested node as viewed in the
All Nodes view. The UID number of a node is located on the bottom-left
of the screen.
Telemetry Frequency
1) From the Field View screen, press the Settings softkey, use the
arrows to select Field View Telemetry.
2) Select ENTER.
The TELEMETRY CONFIGURATION screen is displayed.
3) On the TELEMETRY CONFIGURATION screen, press ENTER.
4) Use the arrows to backspace and use the numeric keypad to set the telemetry
frequency between 50 MHz and 1000 MHz, press ENTER.
NOTE: The telemetry frequency must be set to match the frequency at
which the headend modem is broadcasting data.
5) To exit the TELEMETRY CONFIGURATION screen and confirm the new telemetry
frequency setting, press the OK softkey.
Return Signal Generator Frequency/Level
1) From the Field View screen, press the Settings softkey, use the
arrows to select RSG setup.
2) Select ENTER.
The RETURN SIGNAL GENERATOR configuration screen is displayed.
3) On the RETURN SIGNAL GENERATOR configuration screen, press the up or
down arrows to select the desired Frequency or Level text box, press ENTER.
- To set the RETURN SIGNAL GENERATOR FREQUENCY between 5 and 55 MHz (Annex
B) or 5 and 65 MHz (Annex A and C), press the arrows to backspace and
to step the frequency up/down or use the numeric keypad, press ENTER.
- To set the RETURN SIGNAL GENERATOR LEVEL between 8 and 58 dBmV (68 to
118 dBµV) (-40.8 to 9.2 dBm), press the arrows to backspace and to step
the level up/down or use the numeric keypad, press ENTER.
4) To exit the RETURN SIGNAL GENERATOR configuration screen, press the
OK softkey.
