Part 2: 10.1 MHz to 10 kHz Frequency Span Readout Accuracy

Perform \Part 1: 1800 MHz Frequency Span Readout Accuracy" before performing this procedure.

1.Connect the equipment as shown in Figure 2-12. Note that the Power Splitter is used as a combiner.

2.Press 4PRESET5 on the EMC analyzer, then wait for the preset routine to ￿nish. Set the EMC analyzer by pressing the following keys:

4FREQUENCY5 70 4MHz5

4SPAN5 10.1 4MHz5

3.Press INSTRUMENT PRESET on the synthesized sweeper, then set the controls as follows:

CW :: :: :: ::: :: :: :: ::: :: :: :: ::: :: :: :: :: ::: :: :: :: ::: :: :: :: :: ::: 74 MHz

POWER LEVEL :: :: :: ::: :: :: :: ::: :: :: :: :: ::: :: :: :: ::: :: :: :: 05 dBm

4. Set the synthesizer/level generator controls as follows:

FREQUENCY : : : : : : : : : : : : : : : : : : : : : : : : :: : : : : : : : : : : : :: : : : : : : : : 66 MHz

AMPLITUDE : : : : : : : : : : : : :: : : : : : : : : : : : : : : : : : : : : : : : :: : : : : : : : : : : 0 dBm

5.Adjust the EMC analyzer center frequency to center the two signals on the display.

6.On the EMC analyzer, press 4SGL SWP5. Wait for the completion of a new sweep, then press the following keys:
