Overview
To evaluate high-power amplifiers, stimulus signals having greater
amplitude than the maximum output power of the E5071C may be
required. In such cases, perform the transmission/reflection measurement
by configuring an external test set by connecting external couplers/bridges
instead of using the S-parameter test set built in the E5071C.
When you want to use the E5071C for such purposes, use the external test
set mode function.
Example of using the external test set mode function
To apply amplified output signal of the E5071C to the DUT, an amplifier is
connected to the port used for the source to the E5071C. A reverse coupler
is inserted to make the reflection measurement. A forward coupler is
inserted to use the output of the amplifier as the reference signal. This
configuration corrects a source mismatch error caused by the amplifier.
To measure S21 and S11 using this configuration, Mode 1 is selected as
the external test set mode.
