Level and Meter Accuracy (All
Models Except Those Containing Option
004)
a. Performance Check
(1) Connect sensor module 11722A to measuring receiver CALIBRATION RF
POWER OUTPUT. Set measuring receiver to measure RF power, press RF Power CAL
and then save correction factors.
(2) Disconnect measuring receiver from CALIBRATION RF POWER OUTPUT
and connect to RF OUTPUT.
NOTE
The maximum output of TI's with option 002 is +13 dBm and
with options 002/003 is +12 dBm.
(3) Set OUTPUT LEVEL switch to +20 dBm and RANGE MHz switch to 512-256.
(4) Adjust FREQUENCY TUNE control for a 512 MHz indication on
FREQUENCY MHz display and press COUNTER MODE LOCK ON pushbutton.
(5) Set RF OFF/ON switch to ON.
(6) Select the table (5 through 8) that corresponds to the appropriate option(s) of the
TI. Using the techniques of (3) and (4) above set OUTPUT LEVEL, RANGE MHz, and
FREQUENCY TUNE switches to
settings listed in
table selected and
adjust OUTPUT
LEVEL vernier control(s) for meter indications as listed in table. If measuring receiver
indications are not as specified, perform b below.
