1 Cycle Mode
This mode is used to compute items related to the voltage axis or the area over one
cycle after determining the cycle. This mode is suited to items such as Rms and Avg that
produce errors depending on the measurement range.
This mode does not affect the items related to the time axis or the area of the X-Y
waveforms.
Setting the Measurement Range (Time Range1/Time Range2)
By default, the
±
5 divisions of the time axis display frame is the measurement range.
However, this range can be shortened. The measurement range is specified using two
vertical cursors. The measurement start point is the position where the fine dotted line is
located, and the measurement end point is the position where the coarse dotted line is
located. Up to 10 MW from the measurement start point (Time Range1) are measured.
The concept of the measurement range is analogous to the concept of the selectable
range of cursor display position in cursor measurement.
For details, see section 11.4, “Selectable Range of Cursor Position.”
Setting the Distal, Mesial, and Proximal Unit (Dist/Prox Mode)
Select the method of assigning the three levels that are used as references in
measurements such as the rise and fall times.
• %
The distal, mesial, and proximal values are set in terms of percentages when High of
any trace (CH1 to CH16, Math1 to Math8) and Low are taken to be 100.0% and 0.0%,
respectively.
• Unit
Set the distal, mesial, and proximal values of any trace (CH1 to CH16, Math1 to
Math8) to arbitrary voltage or temperature values.
Setting Distal, Mesial, and Proximal
Unit:
Dist/Prox Mode
Proximal range: 0.0 to 99.8 (resolution: 0.1%) or voltage or temperature corresponding
to
±
10 divisions (resolution: varies depending on the module).
Mesial range:
0.0 to 99.9 (resolution: 0.1%) or voltage or temperature corresponding
to
±
10 divisions (resolution: varies depending on the module).
Distal range:
0.0 to 100.0 (resolution: 0.1%) or voltage or temperature
corresponding to
±
10 divisions (resolution: varies depending on the
module).
