SDA-5500/SDA-5510 Sweep Configuration: Forward Sweep Configuration (SDA-5500)

Connect a special Acterna cable between the serial ports of two units.
Ensure that the baud rate is set the same for each unit. A baud rate of
19.2K is recommended for uploading plans.
Select Copy Remote Plan from the menu and press the Enter key. A list
of plans located in the remote units memory will appear. Select the plan
that you want to copy and press the Copy soft key. The selected plan will
be transferred from the remote unit and stored in the unit that you are
operating. It will also become the active plan.
4. At this time, be sure to edit each scrambled channel to ensure that it is
designated appropriately.
5. You can also designate tilt channels and label the channels with call
letters, but this is not essential to begin the sweep process.
6. You might have noticed that the channel plan list included some
channels that were not marked "Enabled". These channels can be
converted automatically to sweep points using the Build Sweep Points
selection from the main CHANNEL PLAN menu. Before doing this,
make sure that these "disabled" channels do not encompass an area
of digital or other signals that you want to avoid sweeping. If they do,
simply edit these particular channels and toggle the Sweep Channel
selection to NO. When this is completed, select Build Sweep Points
from the CHANNEL PLAN menu. Build Sweep Points can convert
each disabled channel into 1, 2, or 3 sweep points.
7. After building the channel plan, you’ll see a display that tells you how
many enabled channels there are, what type of plan it is, and other
information. You can now make measurements, sweep, and perform
other functions that Stealth enables.
Testing the Transmitter Setup
It is best to test the transmitter setup and connection at the headend before
proceeding into the field. The following tips should help in the debugging
process.
• Perform a Scan on the SDA-5500 to verify that signal input levels are
close to what was calculated in Worksheet 1 (above) and that all
channels are present in this Scan. If they're not, use Spectrum mode to
check that they are present, then edit the channel plan to add any stable
and unscrambled channels that are missing.
• Select a test point at a location after all forward path signals are
combined. Connect this to the IN port of an SDA-5000. If the channel
levels are above +20dBmV, pad them down to 0 to +10dBmV.
