4. RF OUTPUT LEVEL ACCURACY AND FLATNESS

4. RF OUTPUT LEVEL ACCURACY AND FLATNESS

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 option) or -5 dBm (for Over 8.5 GHz
Option) at 50 MHz using a power meter. The frequency flatness is tested by
measuring the power level at several frequency points from 9 kHz to 20 GHz
(depending on the option) and calculating the differences between them and
the power meter reading at 50 MHz.

1
1. The DSG (Device Substitution Group) is listed below the equipment description, if
applicable. These devices are required to be mapped in TME to execute a test.
DSGs require either GPIB communication or are important for dynamic measure-
ment uncertainty calculations. N/A refers to required equipment that is not mapped
as DSGs in TME.
2. Over 8.5 GHz are Options 2D5/2K5/4D5/4K5.
3. Up to 8.5 GHz are Options
230/235/430/435/240/245/440/445/260/265/460/465/280/285/480/485.
