NOTE
The RF probe authorized for use with TI must have serial
numbers matching the TI serial numbers. If a new RF probe is
calibrated with TI, annotate new RF probe with TI serial
number. Do not use any RF probe not calibrated with TI.
c. Connect TI to a 115 V ac source.
d. Set OFF-ON switch to ON.
e. Set RANGE-FULL-SCALE switch to .001 VOLTS.
f. Replace RF probe tip with test adapter (50 Ω feedthrough termination.)
g. Adjust BALANCE control for minimum meter detection.
h. Replace test adapter (50 Ω feedthrough termination) with RF probe tip.
i. Allow TI and measuring receiver to warmup for 30 minutes.
8. Accuracy and Linearity
a. Performance Check
(1) Adjust calibrator for wideband operation.
(2) Connect calibrator WIDEBAND OUTPUT (without 50 Ω pad) to TI RF
probe using 50 Ω feedthrough termination supplied with TI.
(3) Adjust calibrator frequency controls for 300 kHz output.
(4) Adjust calibrator voltage output controls for a TI meter indication specified in
below.
(5) Repeat technique of (4) above for remaining RANGE-FULL-SCALE VOLTS
setting listed in table 3.
(6) Set calibrator to standby.
(7) Disconnect RF probe from calibrator output.
