2. Reference level
The reference level, input attenuation, preamplifier and maximum mixing
level maintain coupling relationships. Refer to the introduction of equation
(2-3) in “Ref Level” for more details.
3. Input Attenuation
The input attenuation, reference level, preamplifier and maximum mixing
level maintain coupling relationships. Refer to the introduction of equation
(2-3) in “Ref Level” for more details.
4. RBW
This parameter maintains a coupling relationship with the span. Refer to “RBW”
for more details.
5. VBW
This parameter maintains a coupling relationship with RBW. Refer to “VBW”
for more details.
6. Sweep Time
The sweep time, RBW, VBW and span maintain coupling relationships. Refer
