2. Set the MG3692x Synthesized Signal Generator #1 to 799.951 MHz CW, and set the MG3692x
Synthesized Signal Generator #2 to 800.051 MHz.
3. Turn Off the RF of the MG3692x Synthesized Signal Generator #1 and the MG3692x Synthesized Signal
Generator #2.
4. On the ML2438A power meter, zero the sensor and set the calibration factor to 800 MHz.
5. Connect the power sensor to the power splitter output.
6. On the MG3692x Synthesized Signal Generator #1, turn the RF On, and adjust the RF amplitude so that
–20 dBm appears at the splitter output (approximately +16 dBm).
7. Turn Off the RF of the MG3692x Synthesized Signal Generator #1.
