Measuring Periodically Fluctuating Amplitudes

Cycle Statistics

Cycle Statistics
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 DL1700E Series with its long memory, lets you analyze a long waveform, period-by-period, based on the period of a reference signal.

How can I quickly count a large number of pulses in a waveform?

Pulse count

Pulse Count
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 DL1700E Series, you'll never again have to manually count pulses on screen or on a stack of printouts.

Envelope and Roll modes

Envelope and Roll modes for simultaneously observing both slow and fast signals

Envelope mode always captures signals at the highest sampling rate, irrespective of the time-axis setting. This mode is effective when observing high-frequency noise superimposed on a slow signal. Roll mode allows you to observe signals on the screen in much the same way as you record them on a chart recorder. When in normal mode, you can set the sampling rate as high as 2 MS/s for roll mode. In addition, you can have a roll-mode view of signals in the envelope mode.
