CAUTION
Do not exceed +10 dBm input to TI during this performance
check or damage to TI channel A probe may occur.
NOTE
Ensure AMPLITUDE CHANNEL switch is set to B.
(21) Set AMPLITUDE MV-RANGE-DB switch to 0 dB.
(22) Set variable attenuator to 0 dB.
(23) Set signal generator frequency controls to 30 MHz.
(24) Adjust FREQ RANGE-MHz control for a dial indication that includes 30 MHz.
(25) Adjust signal generator amplitude controls for an AMPLITUDE meter
indication of 0 dB.
(26) Set variable attenuator to dB setting listed in table 4. The AMPLITUDE meter
will indicate within the limits listed in table 4.
