Getting Started Making a Measurement Making a Measurement Let’s begin using the spectrum analyzer by measuring an input signal. Since the internal 50 MHz alignment signal is readily available, we will use it as our test signal. You cannot hurt the spectrum analyzer by using the alignment signal and pressing any of the keys described in this section.
Page 42 Getting Started Making a Measurement If desired, use the reference level function to place the signal peak at the top of the screen using the knob, step keys, or numeric keypad. (Marker functions measure the frequency and amplitude of a signal.) Figure 2-4 demonstrates the relationship between center frequency and reference level.
