Displayed Average Noise Level (DANL)
Procedure
11.The value of the normalized displayed average noise should be less than
the specification value.
12.Change the analyzer center frequency to the next value listed in Table 2-1.
Press: FREQ Channel, Center Freq, [Table 2-1 Value], GHz
13.Repeat step 4 through step 12 to fill in the remainder of Table 2-1 for your
analyzer frequency range.
