Numerator Auto-Return Button Selection Group
• The buttons of the NUMERATOR menu form an auto-return button selection group, where the selection of any one button de-selects all other buttons and auto-returns to the USER-DEFINED menu.
• The possible combinations of the NUMERATOR and DENOMINATOR functions are summarized above in Table: User-Defined Numerator/Denominator Combinations.
A1 (Numerator)
Select specifies that A1, incident power on port 1, will be the numerator value.
A2 (Numerator)
Select specifies that A2 will be the numerator value.
B1 (Numerator)
Select specifies that B1, received power on port 1, will be the numerator value.
B2 (Numerator)
Select specifies that B2 will be the numerator value.
1 (One) (Numerator)
Select specifies that 1 (one) will be the numerator value.
