Dependencies / 
Couplings
Sweep time in non-zero span is coupled to RBW. As the RBW 
changes, the sweep time is changed to maintain amplitude 
calibration. 
When Res BW is set to Auto, resolution bandwidth is 
autocoupled to span. The factory default for the Span to RBW 
ratio is approximately 106:1 when auto coupled. When Res 
BW is set to Man, bandwidths are entered by the user, and 
these bandwidths are used regardless of other analyzer 
settings.
Preset 5 MHz, Auto
State Saved Saved in instrument state.
Range 10 Hz to 200 kHz, plus bandwidths of 250 kHz, 300 kHz, 
1 MHz, 3 MHz, or 5 MHz
