synthesized signal generator 1464C.
2) Set the output power level frequency of the signal generator to -13dBm and the output frequency to 100
MHz.
3) Press
【
Preset
】
on the spectrum analyzer, and set it as follows:
Center frequency .............................................................................................................................. 100 MHz
Span .................................................................................................................................................... 100 Hz
Reference level ................................................................................................................................. -10 dBm
Attenuation ............................................................................................................................................. 0 dB
Resolution bandwidth ........................................................................................................................... 10 Hz
4) Wait for completion of the new sweep, and press

and [Detla]. In this case, the attenuator
attenuation value at 0 dB can be made as a reference.
5) Set the spectrum analyzer; press
【
Ampt
】
[Attenuation Automatic Manual], and set the attenuation value of
the attenuator according to the test form.
6) After the sweep is completed, press
【
Peak
】
, and the amplitude of the current differential marker is the
attenuator switching error.
7) Repeat steps 5-6 until the test of all the attenuation values of the attenuator is completed, and then record the
test result in the 4041 Series Spectrum Analyzer Record Sheet .
