Aux Input; Example Of Aux Input Measurement - Agilent Technologies E5071C Manual

Absolute measurement in Port 2, test receiver
B (n)
Absolute measurement in Port 3, test receiver
C (n)
Absolute measurement in Port 4, test receiver
D (n)
Absolute measurement in Port 1, reference receiver
R1 (n)
Absolute measurement in Port 2, reference receiver
R2 (n)
Absolute measurement in Port 3, reference receiver
R3 (n)
Absolute measurement in Port 4, reference receiver
R4 (n)
where n in the parentheses is the stimulus port number. For example,
R1(1) means the reference level while the signal is output from the port 1,
and A(2) means the received signal level into port 1 while the signal is
output from the port 2.

AUX Input

The AUX Input Ports can be used to input DC signal for DC signal
measurement. This is useful in cases where the DUT (Device Under Test)
works on a DC supply and it is required to measure the DC supply along
with other measurements of the DUT using the E5071C.
