Performance Verification Tests
26. Frequency Response (Preamp On): Agilent E4402B
15.Set the synthesized sweeper CW frequency to 10 MHz and the
amplitude to 6 dBm.
16.Adjust the synthesized sweeper power level to obtain a Channel A
power meter reading of –20 dBm ±0.1 dB.
17.Record both Channel A and Channel B power meter readings in
Table 2-60.
18.Repeat step 9 through step 12 for each remaining frequency in
Table 2-60.
19.For each entry in Table 2-60, calculate the Splitter Tracking Error as
follows:
For example, if Channel A Power is –20.3 dBm and Channel B power
is –0.23 dBm, the splitter tracking error is –20.07 dB.
