(26) Average V1 indications recorded in (20) above.
(27) Average VC0MP indications recorded in (21) above.
(28) Calculate the CALIBRATOR output level PRF from the below listed formula.
WHERE:
PRF = CALIBRATOR output power level
VC0MP = Average determined in (27) above
= Average determined in (26) above
V1
= Average determined in (25) above
V0
R
= Value recorded in (4) above
Calibration factor = value for thermistor mount at 1 GHz
(29) If calculated PRF is not between 0.955 and 1.045 mW, perform b below.
b. Adjustments
(1) Press CLEAR key.
(2) Connect power meter to CALIBRATOR 1 GHz output.
(3) Press number 7 key.
(4) Press any number key. If power meter indication is negative (e.g., -0.2 dBm),
adjust A3R16 (fig. 1) cw to approximately twice the error or, if power meter indication is
positive (e.g., +0.2 dBm), adjust A3R16 (fig. 1) ccw to approximately twice the error (R).
(5) Press any number key. If power meter does indicate 0.00 dBm, repeat (3) and
(4) above.
(6) Disconnect TI from power meter.
(7) Press CLEAR key.
(8) Connect RF detector A to CALIBRATOR 1 GHZ output.
(9) Press any UNITS key (nS or S or mS key). Wait for TI to calibrate itself
before proceeding to (10) below.
(10) Disconnect RF detector A from CALIBRATOR 1 GHZ output.
(11) Connect RF detector B to CALIBRATOR 1 GHZ output.
(12) Press any UNITS key (nS or S or mS key.) Wait for TI to calibrate itself
before proceeding to (13) below.
(13) Disconnect RF detector B from CALIBRATOR 1 GHZ output.
