Tough Engineering Challenges
Radar- Phase noise degrades sensitivity
- Need to simulate range of return signals
RF/Microwave Comms Systems- Higher order modulation schemes require lower
Error Vector Magnitude to avoid bit errors

Phase Noise Degrades SensitivityDoppler shift proportional to frequency and relative velocity
- 200 kph @ 10 GHz = ~4 kHz- 5000 kph @ 10 GHz = ~93 kHz
Radar
Multiple radar return emulation
MG3690C - generate independent singlet, doublet, triplet and quadruplet pulses
Amplitude leveled down to 100 ns
Radar-Simulation
Simulation of moving target
-Set start delay, stop delay- Set step size (time) and dwell time
Simulation of multiple doublet returns
- Up to 4 pulses- Adjust delays between pulse 2 and 3 t
to test for receiver recovery time
RF/Microwave Comms SystemsEVM /MER caused by noise on signalsHigher order modulation schemes increase bit rate/bandwidth at the expense of more susceptibility to error due to phase noise
QPSK 16 QAM
MG3690C provides low phase noise so can test the system performance and not the limitation of the test equipment
