The Sweep Settings screen provides the following settings.
Use the arrow keys to highlight the item you want to edit on the configuration
screen. Press ENTER to open the
edit box and use the alphanumeric keypad to type your entry or the arrow
keys to select the choice you prefer. Then press ENTER
to complete the edit.
Tilt Compensation (on/off)
The Tilt compensation box contains ON and OFF. NOTE:
The default setting for the tilt compensation is OFF.
Sweep Tilt Compensation is different than the standard DSAM Tilt mode.
Typically Sweep Tilt Compensation is used to adjust the sweep response
on a branch of a network where the branch tilt is not the same as the
mainline network.
Low Tilt Frequency (MHz)
Use the alphanumeric keypad to type your entry (or use the up and down
arrows to increment entry in 10 kHz steps). The range is 5 to 1000 MHz
and the default value is "0.000" MHz.
High Tilt Frequency (MHz).
Use the alphanumeric keypad to type your entry (or use the up and down
arrows to increment entry in 10 kHz steps). The range is 5 to 1000 MHz
and the default value is "0.000" MHz.
Tilt Amount (dB)
Use the alphanumeric keypad to type your entry(or use the up and down arrows
to increment entry in .01 dB steps). The range is -50.0 to +50.0 dB.
Enter in the tilt adjustment required, plus or minus, that will add or
subtract to the mainline network tilt represented in the sweep reference
file which is typically captured at the output of the node amp.
Sweep Limit (on/off)
The Sweep Limit box contains ON and OFF. NOTE:
The default setting for the Sweep Limit is OFF.
Sweep Limit Value
Use the alphanumeric keypad to type your entry. The range is 0.00 to 5.0
dB and the default value is "0.00" dB.
The Sweep Limit Value represents the greatest deviation allowed for a passing
sweep response. The measured deviation is referred to as the sweep Max-Min
value or sweep Peak-to-Valley value, both in dB delta. Thus a Sweep Limit
Value of 2.0 dB will allow a sweep Max-Min value in the DSAM sweep display
no greater than +1.0 to -1.0 dB on either side of the ideal sweep response.
Reverse Sweep Port
The Reverse Sweep Port box contains Port 1 - Bidirectional and Port 2 &endash;
Reverse Only. When Port 2 is selected, both ports are functional for connecting
to directional test points. Port 1 will handle the downstream or forward
traffic while Port 2 handles the upstream or reverse traffic. Other two-way
test modes other than sweep may use this configuration as well, such as
DOCSIS and VoIP testing on directional test points.
