• Computation Source Waveform (Source1 (A), Source2 (B), Source3 (Z))
The options are the same as were described above for the
You can select None (no setting) for only Source3 (Z).
Polarity (Polarity)
Select the Source3 (Z) polarity. You can set this when Source 3 (Z) is not set to None.
Resets the counter when the signal level is high
Resets the counter when the signal level is low
• Determination Level (Threshold)
Set the level for determining changes in the waveform states. Set the level for phase A, phase B, and phase Z.
Selectable range: ±10 div
• Hysteresis (Hysteresis)
Set a width to the level for determining changes in the waveform states so that the instrument does not
perform determination on small fluctuations in the phase.
Selectable range: 0.3 div to 8.0 div
Resolution: 0.1 div
Initial Point (Initial Point)
Set the initial point when integrating, counting edges, or counting rotations. The instrument integrates and counts
by assuming the initial point to be zero.
You can set the initial point numerically or set it to a specific point such as the trigger position or 0 divisions.
Selectable range: –5.00 div to 5.00 div
Resolution: 0.01 div
Setting a Specific Point (Set to)
You can set the initial point to any of the following points.
Trigger Pos (trigger position), −5.00 divisions, 0 divisions, Zoom1 (the center of Zoom1), or Zoom2 (the center of
Zoom2)
When phase Z is used in a rotary count (Source 3 (Z) is CH1 to CH4), the initial point is fixed at –5.00
divisions and does not appear in the setup menu.
Setting Labels and Units (Label/Unit)
Turning Label Display On and Off (Display)
• ON: Shows labels
• OFF: Hides labels
Label (Name)
You can set Math1 to Math4 or Ref1 to Ref4 labels that appear when the label display is turned on. You can use
up to eight characters for labels. The labels that you create are displayed on the screen.
