3. RF OUTPUT LEVEL ACCURACY AND FLATNESS
TEST
Description
This test checks the level accuracy and frequency flatness of the E5071C test port output
signal. The level accuracy is checked for an output power level setting of 0 dBm for up to
8.5 GHz options and -5 dBm for over 8.5 GHz options at 50 MHz using a power meter. The
frequency flatness is tested by measuring the power level at 26 frequency points from 9
kHz to 8.5 GHz and 45 frequency points from 300 kHz to 20 GHz and calculating the
differences of the power meter readings from the level at 50 MHz.
