Tracking Filter (Tracking Filter)
If the sine signal and cosine signal data is changing in a staircase pattern, select a filter that will smooth out the
data that is used to calculate the angle of rotation.
OFF, 2kHz, 1kHz, 250Hz, 100Hz
Scaling (Scaling)
Select how the upper and lower limits of the vertical scale are displayed.
−180Deg to +180Deg, 0Deg to 360Deg, −PI to +PI, 0 to 2PI
* “PI” is displayed as “π” on the screen.
• To improve the calculation accuracy, set the vertical axis sensitivity for each signal so that the signal
amplitude is as large as possible.
• Set the vertical axis sensitivity to the same value for sine signals and cosine signals. If you specify different
values, the DL850E/DL850EV cannot perform calculations correctly.
IIR Filter (IIR Filter)
This can be used to filter the waveform that has been set to Source with the same characteristics of the IIR filter
of the digital filter. You can set the frequency to values over a wider range than is available with the IIR filter of
the digital filter. This function can be used on models with firmware version 2.00 and later.
Math Source Waveforms (Source)
The options are the same as were described above for basic arithmetic.
Filter Band (Filter Band)
Select the filter band.
Low-Pass, High-Pass, Band-Pass
Cutoff Frequency (CutOff)
