Procedure 1. Connect equipment as shown in Figure 2-3.

2.Press QNsTR PRESET] on analyzer.

3.Press [CENTER FREQUENCY] 100 MHz, [FREQUENCY SPAN_) 200 Hz.

4.Connect synthesized sweeper tot spectrum analyzer RF input 2.

5.On synthesized sweeper, select external REFERENCE and key in (jj’ 0 dBm.

6.Press Icw] and key in 99.999 910 MHz.

7.Press MARKER [PEAK SEARCH) on spectrum analyzer and record marker reading under FREQ C of Table 2-3.

8.Set synthesized sweeper frequency to 100.000 090 MHz.

9.Press MARKER [PEAK SEARCH] and record marker reading under FREQ D of Table 2-3.

10.Repeat the span measurement procedure of steps 6 through 9 for each frequency span listed in Table 2-3.

11.Determine the frequency difference between the two measured points. Enter this value under the A DUT column in ‘fable 2-3.

12.The frequency span error is the difference between A DUT and A SYNTH. (See table 2-3 for values). Calculate the span error and record it in Table 2-4.

13.Compare the table 2-4 spec to the span error value calculated in step 12.
