Performance Verification Tests
22. Frequency Response: Agilent E4401B and E4411B
calibration factor of the reference sensor for 100 kHz.
75
Inputs, Option 1DP: Use the calibration factor of the reference
sensor for 1 MHz.
4. On the power meter, set the Channel B calibration factor to 100%.
Do not change this calibration factor during this test.
5. Set the source frequency to 100 kHz and amplitude to –4 dBm.
75
Inputs, Option 1DP: Set the source frequency to 1 MHz and
amplitude to 2 dBm.
6. Adjust the source amplitude to obtain a Channel A power meter
reading of –10 dBm
±0.1 dB.
7. Record the source amplitude setting, and both the Channel A and
Channel B power meter readings in Table 2-40.
8. Tune the source to the next frequency in Table 2-40.
9. On the power meter, set the Channel A calibration factor to the
calibration factor of the reference sensor for the current source
frequency.
10.Adjust the source amplitude to obtain a Channel A power meter
reading of –10 dBm
±0.1 dB.
11.Record the source amplitude setting, and both the Channel A and
Channel B power meter readings in Table 2-40.
12.Repeat step 8 through step 11 for each frequency in Table 2-40.
13.For each entry in Table 2-40, calculate the Splitter Tracking Error as
follows:
For example, if Channel A Power is –10.05 dBm and Channel B
Power is –10.23 dBm, the Splitter Tracking Error is 0.18 dB.
NOTE Tracking errors are nominally –5.7 dB when using the minimum loss
pad.
Splitter Tracking Error Channel A Power Channel B Power=
