NOTE

The accuracy of the 50 ohm termination is extremely critical for

the following voltage measurements.

Measure the DC

resistance of the termination prior to use and select a

termination as close to nominal 50.00 Ω as possible.

Termination must not exceed 0.2% (49.90 Ω - 50.10 Ω). TI

Leveling head should be supported as poor alignment with the

termination may degrade the measurement.

(4) Remove the Leveling Head from the TI base unit. Connect the TI output to the

INPUT 1 of the AC measurement standard using a precision 50 ohm termination.

(5) Set the TI to OPER.

(6) Using the blue arrow keys and the rotary knob, edit the TI Actual output until

the AC measurement standard indicates the target value stated. Press Accept Target.

(7) Press Next Target.

NOTE

To measure directly on the AC measurement standard, use the

TI UNITS key to select Vrms.

(8) Repeat (6) and (7) above for all points requiring the use of the AC measurement

standard. Upon completion, set the TI to STBY.

(9) Zero and Calibrate power meter and power sensor.

(10) Disconnect the AC measurement standard and the 50 ohm precision

termination from the TI base unit. Connect the TI SMA output directly to the input of the

power sensor. Do not use a cable between the TI output and the power sensor input.

(11) Set the TI to OPER.

(12) Using the blue arrow keys and the rotary knob, edit the TI Actual output until

the power meter indicates the Target value stated. Press Accept Target.

(13) Press Next Target.

(14) Repeat (11) through (13) above for all points requiring the use of the power

meter and power sensor. Set the TI to STBY.

(15) Remove power meter and power sensor and replace with measuring receiver

using sensor module (opt 504).

(16) Set the TI to OPER.

NOTE

The measuring receiver will be used in the Tuned RF Level

mode. Calibration of the measuring receiver at the frequencies

and levels used must be accomplished before the measurement

can made taken.

(17) Set the measuring receiver for a tuned level measurement at each applied

frequency and level.
