11. Output Level and Meter Accuracy (All Models Except Those Containing
Option 004)
a. Performance Check
(1) Connect measuring receiver to RF OUT.
NOTE
The maximum output of TIs with option 002 is +13 dBm and
with options 002/003 is +12 dBm.
(2 Set OUTPUT LEVEL switch to +20 dBm and RANGE MHz switch to
512 - 256.
(3) Adjust FREQUENCY TUNE control for a 512 MHz indication on
FREQUENCY MHz display and press COUNTER MODE LOCK ON pushbutton.
(4) Set RF OFF/ON switch to ON.
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.
