Test Device (DUT) Considerations
In order to test a device, the required input RF level and the expected
device output RF level must be determined.
The RF level at Port 1 must be set for the device input RF power level
required. Attenuation can be added in steps of 10 dB up to 70 dB using
the built-in source attenuator. Amplification can be added by removing
the front panel loop and adding an external amplifier.
Before calibration, ensure that the test setup is correct by setting the
power level and adding attenuation as needed.
