High Tilt Fre-
quency
Use the up and down arrows to increase or
decrease the value in 10 kHz increments. The valid
range is 6.00 to 1,000.00 MHz. The default value is
1,000.00 MHz.
Tilt Amount
The tilt adjustment required (positive or negative),
that adds to or subtracts from the mainline network
tilt represented in the sweep reference file (which is
typically captured at the output of the node amp).
Use the up and down arrows to increase or
decrease the value in .01 dB increments. The valid
range is -50.0 to +50.0 dB. The default value is 0.0
dB.
Sweep Limit
Valid options are On and Off. The default option is
Off.
Sweep Limit
Value
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 allows 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. The
valid range is 0.00 to 5.0 dB. The default value is
2.00 dB.
Reverse Sweep
Port
Valid options are Port 1 - Bidirectional and Port 2 -
Reverse Only. If you select Port 2, both ports are
functional for connecting to directional test points.
Port 1 handles the downstream or forward traffic
while Port 2 handles upstream or reverse traffic.
Two-way test modes other than sweep may use this
configuration as well, such as DOCSIS and VoIP
testing on directional test points. The default option
is Port 2 - Reverse Only.
NOTE:
–
If Port 1 is selected, both upstream and down-
stream traffic is handled through Port 1.
–
Reverse Sweep Port only applies to DSAM
6000 models.
