Table 2-46 Noise Bandwidth for C/N Ratio Measurement

Parameter

Description

Default

2 MHz

Range

33 Hz to 2.5 GHz

Unit

GHz, MHz, kHz, Hz

Knob Step

Noise BW/100, the minimum is 1 Hz

Arrow Key Step

in 1-1.5-2-3-5-7.5 sequence

Carrier BW

Set the bandwidth of the carrier to be measured.



The carrier bandwidth is related to the noise bandwidth and the range
available is from noise bandwidth/20 to noise bandwidth×20.



You can use the numeric keys, the knob, or the arrow keys to modify the
parameter.
