Table 7
Path Insertion Loss Test Instructions
1. In the RF Path Description in the tables below, connect the PNA-X Port 1 test cable to
the first designated Test Set Port, and PNA-X Port 2 test cable to the next Test Set port.
2. You will be instructed to enter a specific Test Set SCPI command in the Command
Window using this format: ROUT:SEQ:TRIG: <SCPI Command> [Send Command]
3. Follow the test measurement sequence given in
Table 7
and
Table 8
below.
During the following measurement sequence, in order to make the measurements you
will be moving between two PNA-X applications: the Network Analyzer and the
Connection Expert Command Window. Measured results can be recorded on
Table 7 and
Table 8 below.
