Page 39: Chapter4 Test Case
Chapter4 Test Case u Testing Low Level Signal Testing Signal Distortion 4.1 Testing Low Level Signal This section introduces how to test low level signal, and how to differentiate it with the noice in the same spectrum. The following is three methods to test low level signal. 4.1.1 Reduce the Loss of Input The ability of spectrum analyzer to test low signal is limited by the noice produced internally. - Page 40 1) Reduce the span to 1 MHz. If need, move the peak value to the center of screen again. l Press SPAN →1 MHz 2) Set the attenuation as 20 dB. Pay attention that when the attenuation increases, the bottom of noice will be more close to signal level. l Press AMPT→Attenuation→...

Page 41: Reduce The Resolution Bandwidth
4.1.2 Reduce the Resolution Bandwidth The internal noice level is influenced by resolution bandwidth, but continuous wave signal is not. Decrease RBW into 10%, and the bottom noise will also decrease 10 1) Reset spectrum analyzer 2) Set the frequency of signal source and amplitude as 1 GHz and -80 dBm. Connect the RF OUT port of signal source to the RF IN port of spectrum analyzer and turn on the signal output. -
Page 42: Trace Average
4.1.3 Trace Average Taking the average is the digital processing. It is to plus current value in each trace point and previous average value, and then take the average. Choose the operation of taking average. When spectrum analyzer is doing the automatic coupling, it can make the displayed noise level get smooth to change detection mode into sampling mode. -
Page 43: Measuring Signal Distortion
4.2 Measuring Signal Distortion This selection introduces how to recognize and measure signal distortion. Recognize the distortion produced by spectrum analyzer. The high level input signal may cause the distortion signal produced by spectrum analyzer. This distortion signal will cover the true signal that needs to be measured in the input signal. - Page 44 1. The center frequency should be changed as the frequency value at the first harmonic wave. Press [MARKER] → PEAK 2. Change the span as 50 MHz, and display the signal in the center of screen again. l Press [SPAN] → 50MHz l Press [MARKER] →...
- Page 45 6. Press [AMPT] → Attenuation → 10dB to turn up the RF attenuation to 10 dB. The reading of amplitude difference is influenced by two factors: 1) To increase input attenuation will make signal to noise ratio (SNR) worse which will cause the reading to be positive.
