9. Application example

The output signal generated by the KINAX 3W2 is needed both for local and remote measurement.
Problem:
Is the burden R2 connected across the output signal of the isolating transformer type 84-2I1-10 sufficient for local measu-
rement? If not, then use, for example, SINEAX TV 808.
