2. Connect equipment as shown in Figure 4-16. Note that the 10-dB attenuator is placed between the power
splitter and spectrum analyzer INPUT 5(M2 connector.
3. Adjust signal generator OUTPUT LEVEL control for a power meter reading of
spectrum analyzer INPUT 5(X2 connector).
4. Adjust spectrum analyzer TUNING control to center 50 MHz signal on CRT. Set Amplitude Scale control
to 1 dB/DIV and adjust REF LEVEL FINE control to place peak of signal at a convenient horizontal
graticule line other than top graticule line.
5. Adjust signal generator OUTPUT LEVEL control for a power meter reading of 0 dBm
spectrum analyzer INPUT 5(M2 connector).
6. Set spectrum analyzer REFERENCE LEVEL control to 0 dBm, leaving REF LEVEL FINE control at
setting established in step 4. Record deviation of signal peak from reference graticule line of step 4 (step-
gain error). Values above reference line are positive
