measurement frequency [Hz]) s, measurement range of 10 mVrms to 7
Vrms, and both ports have the same range. Z, gain and phase variation
for when the signal level changes from full-scale (max. 3 Vrms) of
measurement range to 3/10. The input signal is 1:1 or 1:0.3 between
port.

Conditions: Largest or more of measurement time setting 100 ms and (10 ÷
measurement frequency [Hz]) s, and measurement range of 10 mVrms
to 7 Vrms. Z, gain and phase errors when difference of the
measurement ranges of both port is one and the input signal levels are
the same for both ports (full scale level of smallest measurement range,
max. 3 Vrms).
