(a) INPUT PORT to POINT A.
(b) SIDEARM PORT to POINT B.
(c) OUTPUT PORT to 50 : termination.
(d) AUX (TEST) SIDE ARM PORT (if any) to 50 : termination.
(27) Adjust signal generator No. 1 for a power meter indication as recorded in table
E1 as Power meter reading.
(28) Press 39.2 SPCL and enter the First RF Cal Fac from table E1 for the
appropriate frequency, and press the BLUE (SHIFT) % CAL FACTOR (MHz) keys.
(29) Press 39.3 SPCL and enter the Second RF Cal Fac from table E1 for the
appropriate frequency, and press the BLUE (SHIFT) % CAL FACTOR (MHz) keys.
(30) Press 39.4 SPCL, enter the Set ref cal fac from table E1 for the appropriate
frequency, and press the BLUE (SHIFT) % CAL FACTOR (MHz) keys.
(31) Record measuring receiver indication. Measuring receiver indication will be
within the nominal coupling value (coupling variation) + ( frequency sensitivity)
tolerances listed for TI in Appendix A.
(32) Repeat steps (21) through (25) and (27) through (31) above for remaining test
frequencies recorded in table E1.
(33) Repeat steps (21) through (30). Replace step (26) with the following:
Connect TI into figure 7 equipment setup as listed in (a) through (d) below:
(a) OUTPUT PORT to POINT A.
(b) SIDEARM PORT to POINT B.
(c) INPUT PORT to 50 : termination.
(d) AUX (TEST) SIDEARM PORT (if any) to 50 : termination.
(34) Record measuring receiver indication. Measuring receiver indication will be
greater than or equal to the value listed in TI directivity column, Appendix A.
(35) Repeat steps (21) through (25) and (27) through (30). Measuring receiver
indication will be greater than or equal to the value listed in TI directivity column,
b. Adjustment. No adjustments can be made; however, a correction chart may be
prepared listing actual coupling and directivity values at test frequencies.
