Low Level SWR, Return Loss Calculation
In each row in the preceding table compute the "Actual" return loss
using the following formula:
"Ref."
- "Reflected"
=
"Actual"
Verify that "Actual" is greater than the specified Min.
NOTE
If you wish to compute the actual SWR from the
return loss at each frequency, you may use the
following formula:
J -|_ M Q-(Return Losa/20)1
SWR =
1 _ M Q-(Retum Loss/20)1
