Selecting Measurement Parameters
The E5071C allows users to evaluate the DUT (device under test)
characteristics by using the following measurement parameters.
• S-parameters
• Absolute
• AUX Input

Operation Procedure
1. Press Channel Next (or Channel Prev) and Trace Next (or Trace Prev)
to select the trace for which measurement parameters will be set up.
2. Press Meas.
3. Click a softkey that corresponds to the desired measurement
parameter.
S-parameters
S-parameters (scattering parameters) are used to evaluate how signals are
reflected by and transferred through the DUT. An S-parameter is defined
by the ratio of two complex numbers and contains information on the
magnitude and phase of the signal. S-parameters are typically expressed
as follows:
S
out in
out: port number of the DUT from which the signal is output
in: port number of the DUT to which the signal is input
For example, S-parameter S
21
is the ratio of the output signal of port 2 on
the DUT with the input signal of port 1 on the DUT, both expressed in
complex numbers.
When the balance-unbalance conversion function is turned on, the Mixed
mode S-parameters can be selected. Refer to Evaluating Balanced Devices
(balance-unbalance conversion function for more information.
Absolute
Absolute shows the absolute power for reference and received signals on
the port.
