INSTRUCTION MANUAL MC-377+.
EXAMPLE B.- Measuring the power of a digital signal
Take the following figure as an example, showing a digital signal:
Figure 9.- Example of digital channel power measurement.
Using the CH POWER scale [32] (blue background) you can read a power
of 45 dBµV.
From the correction chart in figure 8, you obtain the Correction Factor to be
applied to the frequency you are working with (650.00 MHz) which is 0 dB. Therefore,
the actual power of the channel is:
Power [dBµV] = Reading (45 dBµV) + Atten. (0 dB) + Correct. Factor (0 dB) = 45 dBµV
To obtain further information on the digital signal measurement method refer to
