Perform the following keypress sequence required for your format type.
For Custom Format
Press
Return > Custom Off On.
For TMDA Formats
Press
Return > Return > More (2 of 2) > desired format Off On.
This generates the custom modulation or TDMA state with user-defined burst shape created in the previous
sections. During waveform generation, the CUSTOM (or appropriate TDMA) annunciator and I/Q
annunciator activate. The waveform is now modulating the RF carrier.
Configuring the RF Output
1. Set the RF output frequency to 800 MHz.
2. Set the output amplitude to −10 dBm.
3. Press
RF On/Off.
The current real-time I/Q baseband digital modulation format with user-defined burst shape is now available
at the signal generator’s RF OUTPUT connector.
