a. Performance Check
(1) Connect attenuation measurement equipment as shown in figure 4.
Figure 4. Attenuation measurement - equipment setup.
(2) Select one TI attenuator.
(3) Adjust equipment to measure attenuation at lowest frequency as indicated on
calibration correction chart of TI attenuator selected in (2) above. Measured attenuation
will be within 0.3 dB of attenuation value specified on calibration chart.
(4) Repeat technique of (2) and (3) above at remaining frequencies indicated on
calibration chart of TI attenuator.
(5) Repeat (2) through (4) above for remaining TI attenuators.
or prepare new calibration chart.
