NOTE: QAM constellation files can take a long time to
save and to view. While saving, the SDA-5000 displays a
message dialog informing you to wait until the process
finishes. The unit employs a streaming file load and
display.
Sweep References enables you to select, store, or delete sweep reference
files. There are four categories of sweep reference files:
• FWDSWP (Forward Sweep) In Forward Sweep the instrument
communicates with the headend, but does not transmit. A headend
transmitter provides the sweep signal downstream.
• REVSWP (Reverse Sweep) (OPT2): In Reverse Sweep, the SDA-5000
does transmit a signal upstream to the headend, and communicates with
the headend.
