Res BW Manual
Opens an edit dialog box to enter a value for the resolution bandwidth. The available
resolution bandwidths are specified in the data sheet.
For details on the correlation between resolution bandwidth and filter type refer to
Chapter 6.2.6.3, "Selecting the Appropriate Filter Type" , on page 366.
Numeric input is always rounded to the nearest possible bandwidth. For rotary knob or
UP/DNARROW key inputs, the bandwidth is adjusted in steps either upwards or down-
wards.
The manual input mode of the resolution bandwidth is indicated by a green bullet next
to the "RBW" display in the channel bar.
When measuring Spurious Emissions, using this softkey automatically opens the
"Sweep List" dialog (see
"Sweep List dialog box" on page 289).
Remote command:
[SENSe:]BANDwidth|BWIDth[:RESolution]:AUTO
on page 830
[SENSe:]BANDwidth|BWIDth[:RESolution]
on page 670
Res BW Auto
Couples the resolution bandwidth to the selected span (for span > 0). If you change the
span, the resolution bandwidth is automatically adjusted.
This setting is recommended if you need the ideal resolution bandwidth in relation to a
particular span.
Remote command:
[SENSe:]BANDwidth|BWIDth[:RESolution]:AUTO

Video BW Manual
Opens an edit dialog box to enter the video bandwidth. The available video bandwidths
are specified in the data sheet.
Numeric input is always rounded to the nearest possible bandwidth. For rotary knob or
UP/DOWN key inputs, the bandwidth is adjusted in steps either upwards or down-
wards.
The manual input mode of the video bandwidth is indicated by a green bullet next to
the "VBW" display in the channel bar.
Note: RMS detector and VBW.
