3.5 Setting the Coupling Mode

NOTE
3.5 Setting the Coupling Mode
For the channel of which the analysis results are shown on the screen only,
press the
SHIFT
key then use the
CURSOR
key to switch.
It is also possible to change the setting in the STATUS/Units screen.
Refer to Section 4.2, "Setting the Coupling Mode" in the instruction manual
of the 3194.
･
When AC mode (coupling mode) is selected on the 3194 product, a DC
blocking filter is required on the input unit. Therefore, if the measurement
frequency is 10 Hz or below, or the waveform has a superimposed DC
component (e.g. a half-wave rectified signal), errors may become large.
･
Analysis results in the DC mode and analysis results in the AC+DC mode
are the same.
･ When the AC+DC or DC mode is selected, a value is shown with a
harmonic index of "0." This shows the DC component included in the
analysis data. However, the polarity is not displayed for the voltage and
current since the effective value is converted.
