Performance Verification Tests
31. Spurious Responses: Agilent E4402B and E4403B
3. Perform step 4 through step 29 using the information and entries
from Table 2-71. Then continue with step 30 through step 38.
4. Press Blue Key, Special, 0, 0 on the signal generator. Set the frequency
to F1 in Table 2-71 for TOI Test 1. Set the amplitude to 4 dBm.
5. Press PRESET on the synthesized sweeper, and set the frequency to
F2 in Table 2-71 for TOI Test 1. Set the synthesized sweeper controls
as follows:
POWER LEVEL, –10 dBm
RF Off
6. Enter the power sensor calibration factor for the signal generator
frequency into the power meter.
7. Adjust the amplitude of the signal generator until the power meter
reads –12 dBm ±0.1 dB.
8. Disconnect the power sensor from the directional bridge. Connect
the directional bridge directly to the analyzer input using an adapter
(do not use a cable).
CAUTION Support the directional bridge and low pass filter to minimize stress on
the analyzer input connector.
9. Press Preset on the analyzer. Press the Factory Preset softkey, if it is
displayed. Press System, Alignments, Auto Align, Off. Set the analyzer
center frequency to the F1 value for TOI Test 1 in Table 2-71. Then,
set the analyzer by pressing the following keys:
FREQUENCY, CF Step, 50 kHz (Man)
SPAN, 20 kHz
AMPLITUDE, More, Y Axis Units (or Amptd Units), dBm
AMPLITUDE, Ref Level, –5 dBm
AMPLITUDE, Attenuation, 5 dB (Man)
BW/Avg, 1 kHz (Man)
BW/Avg, Video BW, 300 Hz (Man)
Peak Search (or Search), More
Search Param (or Search Criteria), Peak Excursn, 3 dB
10.On the analyzer, press the following keys:
Peak Search (or Search)
