The resolution bandwidth is the width of the narrowest measurable band of frequencies in a Spectrum View trace. By default, the RBW tracks the span value in a 1000:1 ratio. The RBW determines the level to which the instrument can resolve individual frequencies in the frequency domain. For example, if the input signal contains two carriers separated by 1 kHz, you will not be able to discriminate between them unless the RBW is less than 1 kHz.

Usage

Using the .query() method will send the SV:RBW? query.
Using the .verify(value) method will send the SV:RBW? query and raise an AssertionError if the returned value does not match value.
Using the .write(value) method will send the SV:RBW value command.

<NR3> specifies the width of the narrowest measurable band of frequencies in a Spectrum View trace, in Hz.
