Performance Verification Tests
6. Frequency Span Accuracy: Agilent E4402B, E4403B, E4404B, E4405B, E4407B, and E4408B
6. Frequency Span Accuracy:
Agilent E4402B, E4403B, E4404B, E4405B,
E4407B, and E4408B
For testing each frequency span, two synthesized sources are used to
provide two precisely-spaced signals. The analyzer marker functions
are used to measure this frequency difference.
There are no related adjustment procedures for this performance test.

Procedure
Full Span Frequency Span Readout Accuracy
1. Connect the equipment as shown in Figure 2-6. Note that the power
splitter is used as a combiner. The synthesized signal generator
provides the frequency reference for the synthesized sweeper.
2. Press
Preset on the analyzer. Press the Factory Preset softkey, if it is
displayed. Set the analyzer by pressing the following keys:
FREQUENCY, Stop Freq, 3 GHz
3. Press PRESET on the synthesized sweeper and set the controls as
follows:
CW, 2700 MHz
POWER LEVEL
, –5 dBm
4. On the synthesized signal generator, set the controls as follows:
FREQUENCY, 300 MHz
AMPLITUDE
, 0 dBm
