BW/Avg
Activates the resolution bandwidth function and accesses the menu
keys that control the bandwidth functions and averaging.
Res BW
Auto Man
Changes the 3 dB resolution bandwidth on the analyzer from 1 kHz to
5 MHz in a 1, 3, 10 sequence using the knob or step keys. If an
unavailable bandwidth is entered using the numeric keypad, the closest
available bandwidth in the 1, 3, 10 sequence is used. (For ESA-E Series
analyses, Option 1DR provides additional 300 Hz, 200 Hz, 100 Hz,
30 Hz and 10 Hz bandwidths. For software revision A.08.00 and later,
the bandwidth range is from 1 Hz to 5 MHz if you have both Options
1D5 and 1DR.) (For ESA-L Series analyses, Option 1DR provides
additional 300 Hz, 200 Hz, and 100 Hz bandwidths.) As the resolution
bandwidth is decreased, the sweep time is modified to maintain
amplitude calibration. Resolution bandwidth is also related to span. As
span is decreased, the resolution bandwidth is decreased. As the
resolution bandwidth changes, the video bandwidth, if in auto couple
mode, changes to maintain the VBW/RBW ratio.
NOTE
With software A.08.00 and greater, in zero span, the auto/manual
function of this key is not applicable. When
Res BW (Auto)
is selected in
non-zero span, any changes to Res BW while in zero span will revert to
the Auto value when you return to non-zero span. When
Res BW (Man)
is
selected in non-zero span, any changes to Res BW while in zero span
will be maintained when you return to non-zero span.
A “
#
” mark appears next to
Res BW
on the display when it is not
coupled. To recouple the resolution bandwidth, press
Res BW (Auto)
(or
press
Auto Couple, Auto All
). The resolution bandwidth can be changed
using the step keys, the knob, or the numeric keypad.

Video BW
Auto Man
Changes the analyzer post-detection filter from 30 Hz to 3 MHz in a 1,
3, 10 sequence using the knob, step keys, or the numeric keypad. If an
unavailable bandwidth is entered using the numeric keypad, the closest
available bandwidth in the 1, 3, 10 sequence is used. (Option 1DR
provides additional 1 Hz, 3 Hz and 10 Hz video bandwidths when the
resolution bandwidth is
≤
300 Hz.)
As the video bandwidth is decreased, the sweep time is increased to
maintain amplitude calibration. A “
#
” mark appears next to VBW on
the bottom of the analyzer display when it is not coupled. To couple the
video bandwidth, press
Video BW
(Auto)
(or press
Auto All
).
