DUT:
- Test frequencies 93, 520, 749, 751, 1499, 1501, 2500, 3000,
3001, 4399, 4400, 5499, 6000 MHz
- Test levels P
min
unmodulated and P
min
with I/Q modulation, dc input at max. level
Recommended settings on analyzer:
- Sample detector
- Frequency far from the carrier:
AMPT/MIXER/MIXER LVL MANUAL –5 dBm
Resolution bandwidth 30 kHz
Video bandwidth 1 kHz
Span 10 MHz
- Frequency at 50 kHz to 1 MHz from the carrier:
Resolution bandwidth 1 kHz
Video bandwidth 1 kHz
Average over at least 3 sweeps.
Note:
Some of the nonharmonics suppression values to be measured are
outside analyzer specifications. In case of doubt, the measurement
must be repeated with a 3 dB attenuator at the analyzer input. If
the nonharmonics suppression changes, the nonharmonics come
from the analyzer. Because of the bell-shaped noise of the analyzer
in the vicinity of the carrier, smaller resolution bandwidths may
have to be used.
