Edge Count (Edge Count)
Counts the number of slope edges of the waveform that has been assigned to Source. You can use this to count
the number of events in consecutive tests.
Math Source Waveform (Source)
The options are the same as were described above for basic arithmetic. However, you can select an input
channel of a logic module (select the channel, and then select the bit). You cannot select an input channel of a
frequency module.
Slope (Slope), Level (Level), Hysteresis (Hysteresis)
Set the slope (rising or falling), the signal level, and the hysteresis of the edges that you want to count. These
settings are shared with the
Reset Condition (Reset Condition)
Select the condition for resetting the count from one of the settings below.
• Start (Start): When the waveform acquisition starts
• Overlimit (Overlimit): When “Value/Div” e10 div or falls below −10 div
Manual Reset (Manual Reset)
To manually reset the count, select Execute.
Resolver (Resolver)
Calculates the angle of rotation from the sine signal and cosine signal that are generated from the detection coils
of the resolver depending on the angle of the rotor. This function can be used on models with firmware version 2.00
and later.
Sine Phase Signal and Cosine Phase Signal (Sin Ch, Cos Ch)
Select the sine signal and the cosine signal that are generated from the detection coil of the resolver. The
options are the same as were described above for basic arithmetic.
Hysteresis (Hysteresis)
Set the rising edge hysteresis of the excitation, sine, and cosine signals. When the sample point mode (which
is explained below) is set to Auto, this setting is applied to all signals. When the sample point mode is set to
Manual, this setting is applied to the excitation signal.
Sample Point (Sample Point)
Excitation Signal (Carrier Ch)
Select the resolver’s excitation signal. The options are the same as were described above for basic arithmetic.
Mode (Mode)
To enable more accurate calculations of the angle of rotation, set the mode that is used to sample the peak
values of sine and cosine signals.
• Auto: The rising edges of the excitation, sine, and cosine signals are detected, and the peak values of sine
signals and cosine signals are sampled automatically.
• The Auto setting can be applied when the time difference of the sine and cosine signals in reference to the
excitation signal is less than ±90°(π/2).
• Turn the SCALE knob to set the vertical scale (V/div) so that the amplitudes of the excitation, sine, and
cosine signals are all ±1.5 div or greater. If the amplitudes are less than ±1.5 div, the Auto function will not
operate.
• Manual: The rising edge of the excitation signal is detected, and sine and cosine signals at the specified time
(Time) after this detected rising edge are sampled.
Time Setting
Selectable range: 0.1 μs to 1000.0 μs, Default value: 0.1 μs, Resolution: 0.1 μs.
