8. Press the Shift key and then press the Sweep (3) key, then press the Detection soft key and then the Peak
soft key.
9. Press the Freq key and press the Center Freq soft key.
10. Use the keypad to enter 1674 and press the MHz soft key.
11. Press the Span key, use the keypad to enter 2, and press the MHz soft key.
12. Press the BW key and press the RBW soft key.
13. Use the keypad to enter 10 and press the kHz soft key.
14. Press the VBW soft key and use the keypad to enter 1, then press the kHz soft key.
15. Wait until one sweep is completed.
16. Press the Marker key and press the Peak Search soft key.
17. Record the Marker 1 amplitude reading for 1674 MHz into Table A-13, “Measured Input signal level at
1674 MHz” on page A-6.
18. Press the Freq key and press the Start Freq soft key.
19. Use the keypad to enter 100 and press the kHz soft key.
20. Press Stop Freq soft key, enter 1673 and press the MHz soft key.
21. Press the Marker key and press the Peak Search soft key.
22. Record the Marker 1 amplitude reading for 100 MHz into the “Measured Spur Level“ column of
Table A-14, “Calculated Input signal level at 1674 MHz” on page A-6.
23. Calculate the input related spurious level by subtracting the Marker 1 reading in Step 17 from the
Marker 1 reading in Step 22. Record the calculated result into the “Calculated IRS“ column of
Table A-14.
24. Verify that the calculated result is ≤
–60 dBc.
25. Repeat Step 18 through Step 24, setting a start frequency of 1675 MHz and a stop frequency of
2800 MHz.
1701 MHz Input Related Spurious Check:
26. Set the MG3692x output to 1701 MHz, with an RF output level of –30 dBm.
27. On the MS2721B, press the Freq key and press the Center Freq soft key.
28. Use the keypad to enter 1701 and press the MHz soft key.
29. Press the Shift key and then press the Trace (5) key. Press the Trace A Operations soft key.
30. Press the # of Averages soft key, use the keypad to enter 5, and then press the Enter key.
31. Wait until the Trace Count displays 5/5.
32. Press the Marker key, and press the Peak Search soft key.
33. Record the amplitude at 1701 MHz into Table A-15, “Measured Input signal level at 1701 MHz”
on page A-6.
34. Press the Freq key, and press the Start Freq soft key.
35. Use the keypad to enter 26, and press the MHz soft key.
36. Press Stop Freq soft key, enter 28, and press the MHz soft key.
37. Press the Shift key and then press the Trace (5) key. Press the Trace A Operations soft key.
38. Press the # of Averages soft key, use the keypad to enter 5, and then press the Enter key.
39. Wait until the Trace Count displays 5/5.
40. Press the Marker key, and press the Peak Search soft key.
