(8) Vary FREQUENCY VERNIER control to tune TI output frequency from 2.5 to
7.0 GHz while observing power meter indication. Power meter will indicate within 0.7
dBm of value recorded in (7) above; if not, perform b (21) through (27) below.
(9) Enter data 7.1 GHz on keyboard. Power meter will indicate 0.0 1.3 (1.5) dBm.
Record power meter indication.
(10) Vary FREQUENCY VERNIER control to tune TI output frequency from 7.1 to
13.5 GHz. Power meter will indicate within 0.7 dBm of value recorded in (9) above; if not,
perform b (21) through (27) below.
(11) Enter data 13.6 GHz on keyboard. Power meter will indicate 0.0 1.4 (1.6) dBm.
Record power meter indication.
(12) Vary FREQUENCY VERNIER control to tune TI output frequency from 13.6 to
18.0 GHz. Power meter will indicate within 0.8 dBm of value recorded in (11) above; if
not, perform b (21) through (27) below.
(13) Disconnect power meter from RF OUTPUT.
(14) Press function keys and enter corresponding data on keyboard as listed in (a)
through (e) below:

(e)
(15) Press SWEEP TRIGGER SINGLE key.
(16) Connect power meter to RF OUTPUT and RECORDER OUT (rear of power
meter) to EXT/MTR ALC INPUT.
(17) Press ALC MODE MTR key and adjust EXT/MTR ALC CAL for a power
meter indication of -1.0 dBm.
(18) Press SWEEP TRIGGER SINGLE key and observe power meter indication.
Power meter will indicate -1.0 0.2 dBm during the period the SWEEP LIGHT is on.
NOTE
Disregard power meter fluctuations when TI changes bands.
b. Adjustments
NOTE
The exact value of 10 dB attenuator at 50 MHz and 2.2 GHz
must be known before performing this adjustment procedure.
(1) Disconnect power meter from RF OUTPUT.
