Question

6. If a spectrum analyzer is said to have 1 kHz resolution, it means:

a. It is possible to see two signals as close to each other as 1 kHz

b. The range of frequencies that can be seen on the screen is 10 kHz

c. Each horizontal division represents 1 kHz

9. The Rigol 800 series Spectrum Analyzer has 10 horizontal divisions.

A square wave function with a fundamental frequency of 1 MHz at a power level of 10 dBm is connected to the input of the Spectrum Analyzer.

The SPAN is set to 10 MHz.

Including the fundamental frequency, what is the maximum number of frequencies ( vertical trace lines ) will you see on the screen?

a. 2

b. 5

c. 1

Explanation / Answer

6. 1 khz resolution means that two signals having atleast differenc in frequency of 1 khz can be resolved or distinguished. if that difference is less than 1 khz, then this instrument may not be able to distinguish two signals.

so option a is correct

resolution has no relation with range and horizontal division so b and c are wrong
