Waveform Analysis
Measurement Range (Time Range)
As the default, measurement starts at -4div from the display center and extends to +4div, but
you can shorten the range. You make the setting by positioning two vertical lines: a dot-dash
line for the start point, and a dashed line for the end point.
Measurement parameters (Items)
You can select from among the following 26 parameters. You can measure up to a total of
sixteen parameters simultaneously.
• Voltage-axis parameters

+Overshoot
-Overshoot
Max : Maximum voltage [V] Avg : Average voltage (1/n) Σ xi [V]
Min : Minimum voltage[V] Rms : Root mean squeare value (1/ n )( Σ (xi)2)1/2[V]
High : High level voltage [V] P-P : Peak to peak value (Max-Min) [V]
Low : Low level voltage[V] StdDev : Standard deviation (1/n( Σ xi2- Σ (xi)2)1/2
Amp : Amplitude (High-Low) [V] +OShot : Overshoot (Max-High)/(High-Low) [%]
-OShot : Overshoot (Low-Min)/(High-Low) [%]
• Time-axis parameters
+Duty : +Duty rate (+Width)/Period × 100 [%]
-Duty : -Duty rate (–Width)/Period × 100 [%]
Freq : Frequency (Hz]
Period : Period [s]
Rise : Rise time [s]
Fall : Fall time [s]
+Width : Width above mesial value [s]
-Width : Width below mesial value [s]
