TEST AND MEASUREMENT
2. (Figure 23) On the spectrum analyser measure the carrier leakage ratio. Carrier leakage r
the ratio of peak power and the power at 68kHz below peak frequency.
Example:
peak power (902.468MHz) = 33dBm
power at 68kHz below peak power = 0dBm
carrier leakage ratio = 33dBm - 0dBm = 33dBm
Figure 23: Carrier leakage ratio
3. If carrier leakage ratio is greater than 30dBc then unit is OK. (offset calibration is com
4. If carrier leakage ratio less than 30dBc then go to Ich check.
Ich check
1. (Figure 24) At the Channel box check Ich offset data by selecting F7 then VIEW TRIM OTHER.
Figure 24: I, Q data field selection 1.
2. (Figure 25) At the Channel box set Ich offset to 147, press F6 to program TRIM OTHER.
