Table 2-15 VBW/RBW Ratio
Parameter
Remarks
Default
1
Range
0.00001 to 3,000,000
Unit
None
Knob Step
at 1-3-10 step

VBW/RBW Mode
Sets the coupling mode of the VBW/RBW ratio.
Remarks:
When you set VBW/RBW Mode to "Auto", "VBW/RBW Ratio" is in auto
coupling state, and its value is determined by auto rule value. You can set
VBW/RBW Mode to "Manual" or directly set the VBW/RBW ratio to change the
coupling mode.
When you perform the Preset operation, the coupling state is Auto.
Filter Type
Sets the type of the RBW filter.
Remarks:
RSA3000E supports two kinds of RBW filters: Gaussian (-3 dB) or EMI (-6 dB)
When EMI filter is selected currently, the available RBW can only be 200 Hz, 9
kHz, 120 kHz, or 1 MHz. By default, the analyzer uses the Gaussian filter. If the
detector type is "Quasi-peak", then the analyzer automatically switches to EMI
filter.
