key to switch on RF and output RF signals.
Now the RF ON/OFF status area on the front panel operating interface shows “RF ON”.
Step 5. Set the amplitude offset to 5dB.
Edit the amplitude offset as 5dB;
Clockwise (or counterclockwise) turn the front panel knob to select the Ampl Offset edit box in
Power Setting, and make the box editable by pressing the knob or touching the screen. Set the
amplitude offset to 5dB by entering 5dB.
Now the power shown in the main information display area is -5dBm (RF output power (0dBm) –
amplitude reference (10dBm) + amplitude offset (5dB)). The RF actual output power remains 0dBm.
