[SENSe:]BANDwidth|BWIDth[:RESolution] <numeric_value>[M|NM|UM|A]
[SENSe:]BANDwidth|BWIDth[:RESolution]?
Sets the resolution bandwidth. Available resolution bandwidths are 10 nm,
5 nm, 2 nm, 1 nm, and either 0.07 nm or 0.06 nm. The narrowest resolution
bandwidth in 0.7 nm on the HP 86140A and 86143A. It is 0.06 nm on the
HP 86142A and 86145A.
[SENSe:]BANDwidth|BWIDth[:RESolution]:AUTO OFF|ON|0|1
[SENSe:]BANDwidth|BWIDth[:RESolution]:AUTO?
Couples the resolution bandwidth to the wavelength span. SENSe:BAND-
width:AUTO
ON
sets the resolution bandwidth to
span × resolution band-
width ratio
.
[SENSe:]BANDwidth|BWIDth[:RESolution]:RATio <numeric_value>
[SENSe:]BANDwidth|BWIDth[:RESolution]:RATio?
Specifies the ratio of the resolution bandwidth to the span. This parameter is
multiplied by the span width to determine the automatic setting of the resolu-
tion bandwidth. The default ratio is .01.
In the AUTO coupled setting, the resolution bandwidth is controlled by the chosen wave-
length span and the value set for [SENSe:]BANDwidth|BWIDth[:RESolution]:RATio.
The Preset state of the resolution bandwidth coupling is AUTO.
