2. Press System, More, Show System. If there is an entry shown which
reads 1DR: Narrow Resolution BW, and the analyzer is an E4402B,
then enter 10 Hz below as the minimum RBW. If there is an entry
shown which reads 1DR:Narrow Resolution BW and the analyzer is
an E4403B, then enter 100 Hz. Otherwise, enter 1 kHz as the
minimum RBW (resolution bandwidth). Keep this value in mind as
you continue to perform this procedure. Also, take note of whether or
not Option 1DN (3.0 GHz Tracking Generator) and Option 1DS (RF
Preamplifier) are installed.
Minimum RBW____________ Hz
Option 1DN: ____________
Option 1DS: ____________
