Frequency Measurement
For frequency measurement, the items that have to be set for each input signal (CH1 to CH16) include vertical
scales, the vertical positions, FV settings, the input settings, the zoom method, the offset, trace settings, and
linear scaling.
You can connect a sensor or probe to the 701280 (FREQ) frequency module and measure frequencies,
revolutions, periods, duty ratios, power supply frequencies, pulse widths, pulse integration, and velocities.
For the sensor connection method, see section 3.12 in the Getting Started Guide, IM DL850E-03EN. For the
probe connection method, see section 3.5.
