The QAM View option can be factory installed in any new or
existing SDA Series instrument.The specifications and features
are in addition to the standard measurement features of the
SDA Series.When ordering, please specify OPT 4A for 8MHz,
DVB-C, ITU-T J.83 Annex A, or OPT 4B for 6MHz, DVS-031, ITU-T
J.83 Annex B.

Files types that can be stored: Sweepless Sweep, autotests, tilt
graphs, channel plans, and scan graphs. Spectrum graphs
(normal, normal with max hold, and CSO/CTB) can also be
stored. Memory space is allocated on demand. All files stored
as data, not as screen picture.Typical mix of files for 78-
