RES BW
changes the spectrum analyzer 3
dB
resolution bandwidth. As the resolution
AUTO MAN
bandwidth is decreased, the sweep time is increased to maintain amplitude
calibration. Resolution bandwidth is also related to span. As span is decreased,
the resolution bandwidth is decreased. A
“#”
mark appears next to RES BW
on the screen to indicate that it is not coupled. To recouple the resolution
bandwidth, press RES BW AUTO MAN so that AUTO is underlined. The
resolution bandwidth can be changed using the step keys, the knob, or the
numeric keypad.
