Video Demodulation Concepts (Opt. AYH)
RF receiver and 8 MHz spans
Option AYH lets you extend the maximum frequency span of the
H89441A RF receiver from 7 MHz to 8 MHz. Press [ Instrument Mode ] [ receiver ]
[ RF 2-2650 MHz) ] to display the normal (7 MHz) and wide (8 MHz) softkey menu. Press
[ RF (2-2650 MHz) normal ] to configure the RF section for a maximum frequency span of
7 MHz; press [ RF (2-2650 MHz) wide ] to extend the maximum frequency span to 8 MHz.
Option AYH replaces this softkey:
[RF section (2-2650 MHz)]
Remember that, in two-channel analyzers, channel 1 determines the frequency span
of channel 2. Therefore, selecting wide (8 MHz) also extends the frequency span
of channel 2 to 8 MHz (channel 2 is always baseband, so the frequency span is
0 to 8 MHz).
Normal (7 MHz) provides the best specifications. Specifications are located in the
Installation & Verification Guide.
