2 VCOMP (V1 - V0) + V02 - V12
PRF = _________________________________
4 R (Calibration Factor)
Where:
PRF = power reference oscillator output level
VCOMP = value recorded in (11) above
V1 = value recorded in (10) above
V0 = value recorded in (9) above
R = value recorded in (3) above
CALIBRATION FACTOR = value for thermistor mount at 50 MHz
(13) If calculated PRF is not between 0.993 and 1.007 mW, perform b below.
b. Adjustments. Remove TI top cover and set TI POWER REF switch to ON (in) and
adjust A8R4 LEVEL (fig. 5) so that calculated PRF in a (13) above is 1 mW.
16. Final Procedure
a. Deenergize and disconnect all equipment.
b. Annotate and affix DA label/form in accordance with TB 750-25.
