Then after converting the values from the power meter to
Vrms:
response(dB) = 20 log
15 The result from step 14 should be between +3.0 dB and
- 3.0 dB. Record the result in the Performance Test Record
(see page 63).
16 Move the power splitter from the channel 1 to the channel
2 input.
17 Turn off the current channel and turn on the next
channel using the channel keys.
18 Repeat steps 3 through 17 for the remaining channels,
setting the parameters of the channel being tested where
appropriate.
