Step 7: Set the dB reference (Disp-->Ref) at the power meter. The
power meter reading should be 0.00 dB within ±0.01 dB.
Step 8: Set the OA 5000 to each of the settingsin the table below, and
check that the power meter reads within the listed accuracy limits.At
30 db, note the reading.
Step 9: Set the OA 5000 to 0 dB. Check that the power meter reads
0.00 dB within the repeatability sp ecification (±0.05 dB).
Step 10: Set the OA 5000 to 30 dB. Check that the power meter reads
the same as in step 8, within the repe atability specification (±0.05 dB).
Step 11: If the readings in steps 9 and 10 do notmeet the repeatabilit y
specifications, check the connections,and repeat steps 7 to 10.
