4-92 Real-Time I/Q Baseband Generator User’s and Programming Guide
Programming Commands and Examples ESG Family Signal Generators
Programming Examples Options UN8 and 202
PHS
Use this example to configure the signal generator to the initial settings of an PHS
π/4DQPSK modulation sensitivity bit error test. The carrier frequency is 1.89515 GHz at
40 dBuV (displayed in dBm). You can change the PHS format default values once the setup
is complete.
CLEAR and RESET the controller, type the following commands and RUN the program.
