(2) Connect equipment as shown in figure 2.

(3) Adjust synthesized signal generator frequency to 12,370 MHz and RF output

level controls for a -16.5 dBm indication on power meter.

(4) Adjust A6R25 (fig. 1) until YELLOW LED (fig. 1) and GREEN LED (fig. 1) are

on with equal brightness. (R)

(5) Press RESET/LOCAL key.

(6) Adjust synthesized signal generator RF level output controls for a -17 dBm

indication on power meter. YELLOW LED (fig. 1) will be on and GREEN LED (fig. 1) will

be off.

(7) Adjust synthesized signal generator RF level output controls for a -16 dBm

indication on power meter. YELLOW LED (fig. 1) will be off, and GREEN LED (fig. 1) will

be on.

NOTE

If techniques (6) and (7) above fail,

repeat techniques (1) through (5) above.

(8) Press the following keys as listed in (a) through (e) below. TI will display an IF

frequency of 70 MHz.

(9) Connect synthesized signal generator RF output through 20 dB attenuator

(fixed) to power meter.

(10) Adjust synthesized signal generator frequency to 209 MHz and RF output

amplitude controls for a -20 dBm indication on power meter.

(11) Disconnect synthesized signal generator RF output and 20 dB attenuator (fixed)

from power meter.

(12) Connect synthesized signal generator RF output through 20 dB attenuator

(fixed) to INPUT 1 and connect power meter to IF OUT on TI rear panel.

(13) Press SET/ENTER key.

(14) Press the following keys on FUNCTION/DATA keyboard listed in (a) through

(a) DIAGNOSTICS.
