this time, underline of the menu indicates the item is tested completely, for example, [Short-circuit
Device].
j)
Disconnect the short-circuit device, and connect the load to the test port.
k) To test the standard piece after the trace is stable, press [SHORT] to show “Calibrating standard
piece measurement...” during standard piece measurement, and “Connect LOAD in P1,, then press
corresp. menu button to start!” after measurement and error factor calculation. At this time,
underline of the menu indicates the item is tested completely, for example, [SHORT].
l)
After the trace is stable, press [LOAD] to prompt “Calibrating standard piece measurement...” during
standard piece measurement, and prompt “Press [Done] to complete the measurement!” after
measurement and error factor calculation. At this time, underline of the menu indicates the item is
tested completely, for example, [LOAD].
m) Record the error factor, and press [Done] to show the corrected data trace, indicating the correction
is activated.
That is to complete the single port calibration for reflected measurement. The DUT can be connected
and measured at this time.
NOTE:
The open-circuit device, short-circuit device and load can be measured in
any sequence regardless that mentioned here.

Full 2 ports error correction
Full 2 ports error correction can be used to correct 12 error items, including the forward and reverse
directivity, source matching, load matching, frequency response and isolation.
Eliminate directional error during test component assembling in the forward and reverse directions.
Eliminate source matching error during test component assembling in the forward and reverse
directions.
