13. Record the new marker level readout value on the display to the corresponding cell in Table 5-12.
14. Calculate the amplitude deviation by subtracting the new marker value from the 30 kHz RBW
marker reading.
15. Verify that the amplitude deviation is < 0.1 dB.
16. Repeat steps 11 through 16 for the rest of RBW and SPAN combinations in Table 5-12.
