5.2.18 AM Distortion Factor
Test equipment
Test system 5.1.1.1.
Test system 5.1.1.6 (SME06)
Measurement
À Settings at the SME
- Level 0 dBm
- Select LFGEN1 in the MODULATION/AM/AM SOURCE INT menu,
- Modulation depth 30%
- Modulation frequency 1 kHz.
À Vary the carrier frequency from 1 MHz to 1500 MHz (2200/
3000/6000 MHz with SME03E/03/06). For recommended setting
values, see table 5-2.
À Read off the distortion factor at the modulation analyzer.
Distortion factor ..................................................................max. 1%
À Repeat measurement with an AM of 80%.
Distortion factor ..................................................................max. 2%
5.2.19 Residual PhiM with AM
Test equipment Test system 5.1.1.1.
Test system 5.1.1.6 (SME06)
Measurement
À Settings at the SME
- Various test frequencies (for recommended setting values, see
table 5-2)
- Level 0 dBm
- Select LFGEN1 in the MODULATION/AM/AM SOURCE INT
menu,
- Modulation depth 30%
