RR Resolution Bandwidth
Description
The coupling between sweep time and resolution bandwidth is terminated by this command.
Execute RB AUTO to reestablish coupling. (Also see “AUTO.“)
The 200 Hz, 9
kHz,
and 120
kHz
6-dB
resolution bandwidths (used for
EM1
testing) are available
by specifying 200 Hz (for spectrum analyzers with Option 130 installed), 9
kHz,
or 120
kHz
as
the frequency value; the front-panel knob, step increment keys, and auto-coupled settings
provide the 1, 3, 10 resolution bandwidth sequence only. Frequencies are rounded to the
nearest value in the 1, 3, 10 sequence if the frequency is other than 9
kHz,
120
kHz,
5 MHz, or
in the 1, 3, 10 sequence.
The spectrum analyzer provides uncalibrated bandwidths of 300 Hz (10 Hz if the spectrum
analyzer has Option 130 installed in it) and 5 MHz.
