• Edge Detection Source (Edge Source)
The same channel as the math source waveform. Select from U1 to U3 and I1 to I3.
• Hysteresis (Hysteresis)
The same as the standard feature. For details, see “
” in chapter 4.
• Edge Source Filter (Edge Source Filter)
Select from the following.
OFF, 128 kHz, 64 kHz, 32 kHz, 16 kHz, 8 kHz, 4 kHz, 2 kHz, 1 kHz, 500 Hz, 250 Hz, 125 Hz, 62.5 Hz
This is the same as “
” described under “Power Analysis (Power).”
• φ Scaling (φ Scale)
Select how to display phase differences.
Radian: Radian
Degree: Degrees
All Item (Value/Div) Optimization (ALL Output Optimize Value/
Div)
This is the same feature as
of real time math (RealTime Math).
Harmonic Analysis Window Setup (Harmonic Window Setup)
Graph Position (Graph Position)
Select the analysis position on the waveform display of the main screen. The analysis results for the cursor
position are displayed in the graph window.
Main Screen Ratio (Main Ratio)
Set the percentage of the entire waveform display area that the main screen will occupy.
• 50%: The main screen is displayed in the top half of the entire area.
• 20%: The main screen is displayed in the top 20% of the entire area.
• 0%: The main screen is not displayed.
Window Layout (Window Layout)
Set the display layout of the two graph windows.
• Side: Side by side
• Vertical: Top and bottom
Graph Window (Graph Window)
Select from the following.
•
: A bar graph is displayed for the calculated harmonic value of each harmonic up to the 40th harmonic.
•
: The relationship of the phase difference and size (rms value) between the fundamental waves U(1)
and I(1) of the source channel is displayed with vectors.
•
: A numerical list is displayed for the calculated harmonic value of each harmonic up to the 40th harmonic.
