11) Read out the peak value where the marker locates as the displayed average noise level of the 4 GHz to 6 GHz
band when the preamplifier is on, and record it in the corresponding test item of "4041 Series Spectrum
Analyzer Record Sheet". Disable the noise marker and averaging function.
Displayed average noise, preamplifier on (6 GHz~20 GHz)
12) Set the start frequency of the 4041 series spectrum analyzer to 6 GHz and the stop frequency to 20 GHz, with
others left unchanged.
13) Repeat step 3 to step 4.
14) Read out the peak value where the marker locates as the displayed average noise level of the 6 GHz to 20
GHz band when the preamplifier is on, and record it in the corresponding test item of "4041 Series Spectrum
Analyzer Record Sheet". Disable the noise marker and averaging function.
Displayed average noise, preamplifier on (20 GHz~32 GHz)
15) Set the start frequency of the 4041 series spectrum analyzer to 20 GHz and the stop frequency to 32 GHz,
with others left unchanged.
16) Repeat step 3 to step 4.
17) Read out the peak value where the marker locates as the displayed average noise level of the 20 GHz to 32
GHz band when the preamplifier is on, and record it in the corresponding test item of "4041 Series Spectrum
Analyzer Record Sheet". Disable the noise marker and averaging function.
Displayed average noise, preamplifier on (32 GHz~40 GHz)
18) Set the start frequency of the 4041 series spectrum analyzer to 32 GHz and the stop frequency to 40 GHz,
with others left unchanged.
19) Repeat step 3 to step 4.
20) Read out the peak value where the marker locates as the displayed average noise level of the 32 GHz to 40
GHz band when the preamplifier is on, and record it in the corresponding test item of "4041 Series Spectrum
Analyzer Record Sheet". Disable the noise marker and averaging function.
Displayed average noise, preamplifier on (40 GHz~44 GHz)
21) Set the start frequency of the 4041 series spectrum analyzer to 40 GHz and the stop frequency to 44 GHz,
with others left unchanged.
22) Repeat step 3 to step 4.
23) Read out the peak value where the marker locates as the displayed average noise level of the 40 GHz to 44
GHz band when the preamplifier is on, and record it in the corresponding test item of "4041 Series Spectrum
Analyzer Record Sheet". Disable the noise marker and averaging function.
Displayed average noise, preamplifier off (2 MHz~10 MHz)
24) Set the start frequency of the 4041 series spectrum analyzer to 2 MHz, the stop frequency to 10 MHz, the
reference level to -20 dBm, and the preamplifier \OFF, with others left unchanged.
