Performance Verification Tests
6. Frequency Span Accuracy: Agilent E4402B, E4403B, E4404B, E4405B, E4407B, and E4408B
POWER LEVEL, –5 dBm
3. Set the synthesized signal generator controls as follows:
FREQUENCY, 20 MHz
AMPLITUDE, 0dBm
4. Adjust the analyzer center frequency to center the two signals on the
display.
5. On the analyzer, press Single. Wait for the completion of a new
sweep, then press the following keys:
Peak Search (or Search)
Marker, Delta
Peak Search (or Search)
Next Peak
The two markers should be on the signals near the second and tenth
vertical graticule lines (the first graticule line is the left-most).
6. If necessary, continue pressing Next Peak until the active marker is
on the right-most signal (100 MHz). Record the marker delta (∆
Mkr1) frequency reading in the performance test record as Test
Record entry 2.
7. Press Marker, More, Marker Off on the analyzer.
8. Change to the next equipment settings listed in Table 2-9.
9. On the analyzer, press Single. Wait for the completion of a new
sweep, then press the following keys:
Peak Search (or Search)
Marker, Delta
Peak Search (or Search)
Next Peak
10.If necessary, continue pressing Next Peak until the marker delta is on
the right-most signal. Record the marker delta (∆ Mkr1) frequency
reading in the performance test record.
11.Repeat step 7 through step 10 for the remaining analyzer span
settings listed in Table 2-9.
