between cursors with tightened connector showing average return loss of
-34.3 dB from 756 MHz to 3 GHz.
Figure 5.7. S

between cursors with loosened connector showing average return loss of
-26.7 dB from 756 MHz to 3 GHz (7.7 dB excess return loss compared with the tightened
connector in Figure 5.6).
5.5.5. Return Loss (S
11
) Calibration Standards
Many precision Open, Short, and Load standards have unique offset and coefficient values included
with them. By correcting the S
11
trace with these values, the error introduced by these terminators
can be reduced. To apply or change these standards, do the following:
1. Create an S
11
return loss plot using the procedure as described in Section 5.4.
2. Select the S
11
Options menu, then Calibration Standards.
