When the Keysight E4445A spectrum analyzer is being repaired, if measuring a high-power signal greater than 30dBm, it is best to add an attenuator for testing, so as not to burn out the spectrum analyzer due to excessive power; 2. The left side of the spectrum analyzer is the display screen, and the right side is the operation button. On the bottom left is the switch. The operation on the right is divided into 5 parts: FUNCION, MARKE, SYSTEM, CONTROL, DATAENTEY. When a key is selected, the corresponding menu option will appear on the right side of the display screen, and the corresponding operation can be selected by pressing the key next to it. 3. When the Keysight E4445A spectrum analyzer is repaired, the input port of the spectrum analyzer has a maximum allowable safe power input, so the maximum input signal cannot exceed the maximum input level allowed by the spectrum analyzer.
