25. Use the delta marker to measure the difference between the marker frequency
set in step 24 and the specified frequency offset of each marker, and verify
that each value meets the condition as follows:
Delta marker--Marker 1 (--2.86 MHz): < --20 dB
Delta marker--Marker 2 (--3.00 MHz): < --27 dB
Delta marker--Marker 3 (--4.36 MHz): < --49 dB
Use the MASK131.STA setup file for the measurement.
26. Change frequency offset of each marker, and verify that each value meets the
condition as follows:
Delta marker--Marker 1 (2.86 MHz): < --20 dB
Delta marker--Marker 2 (3.00 MHz): < --27 dB
Delta marker--Marker 3 (4.36 MHz): < --49 dB
Use the MASK132.STA setup file for the measurement.
27. Change Center Frequency to 38 on the RTX100A.
28. Change the Center Frequency to 623.143 MHz on the spectrum analyzer.
29. Repeat steps 25 and 26. Use the MASK381.STA and MASK382.STA setup
files for the measurement.
30. Change Center Frequency to 62 on the RTX100A.
31. Change the Center Frequency to 767.143 MHz on the spectrum analyzer.
32. Repeat steps 25 and 26. Use the MASK621.STA and MASK622.STA setup
files for the measurement.
33. Disconnect the 75 Ω BNC (Ma)-to-NC(Fe) adapter, 50 Ω SMA cable, and
50 Ω N(Ma)-to-SMA(Fe) adapter from the RTX100A and spectrum analyzer.
