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)
When the filter band is set to Low-Pass or High-Pass, set the cutoff frequency. The ranges and resolutions are
indicated below.
Filter Band Range Resolution
Low-Pass 0.2 Hz to 3.00 MHz 0.2 Hz (0.2 Hz to 29.8 Hz range)
Default value: 0.30 MHz 2 Hz (30 Hz to 298 Hz range)
0.02 kHz (0.30 kHz to 2.98 kHz range)
0.2 kHz (3.0 kHz to 29.8 kHz range)
2 kHz (30 kHz to 298 kHz range)
0.02 MHz (0.30 MHz to 3.00 MHz range)
High-Pass 0.02 kHz to 3.00 MHz 0.02 kHz (0.02 kHz to 2.98 kHz range)
Default value: 0.30 MHz 0.2 kHz (3.0 kHz to 29.8 kHz range)
2 kHz (30 kHz to 298 kHz range)
0.02 MHz (0.30 MHz to 3.00 MHz range)
Center Frequency (Center Frequency)
When the filter band is set to Band-Pass, set the center frequency. The ranges and resolutions are indicated
below.
Range Resolution
0.06 kHz to 3.00 MHz 0.02 kHz (0.06 kHz to 1.18 kHz range)
Default value: 0.30kHz 0.2 kHz (1.2 kHz to 11.8 kHz range)
2 kHz (12 kHz to 118 kHz range)
0.02 MHz (0.12 MHz to 3.00 MHz range)
