Automatically calculates the maximum value, minimum value, average value, and standard deviation of selected waveform parameters for each period of a signal. You can even find the period corresponding to the calculated maximum and minimum values and display that period in the zoom window. In some applications, like with a PWM (pulse width modulation) control signal, you may need to determine information about each waveform period for long amounts of time. The DL7400 Series with its long memory, lets you analyze a long waveform, period-by-period, based on the period of a reference signal.

Example Applications

• Amplitude, period, and duty ratio for each period in various modulation signals
• Current, voltage, and period for each switching cycle as the load fluctuates in a switching power supply
• Output level of each sensor per revolution in engine or motor
• Clock count in serial data

Automatically counts the number of pulses in the waveform data between cursors. The threshold level for recognizing a single pulse is user-definable, so you can reliably compute pulses even in signals with unstable levels. With the DL7400 Series, you’ll never again have to manually count pulses on screen or on a stack of printouts.

Example Applications

• Stepping motor revolution pulses
• Optical disk tracking error signals
• Interrupt signals from microcontrollers
• Clock count in serial data
