Functions & Advantages

Dynamic frequency sweep

Dynamic frequency sweep is similar to transient mode, repeatedly switching between two parameters. The duration of each parameter is determined by the sweep frequency and duty ratio. It increases from the initial sweep frequency to the cut-off frequency. The frequency increment and frequency point sweep duration are settable. During the sweep, the input voltage is accompanied by a current transient, which causes overshoot and drop. With the functions of voltage ripple and peak-to-peak measurement, various dynamic parameters and corresponding frequencies can be obtained.

 

Voltage ripple measurement

By adjusting the voltage and current signals, the peak-to-peak value of the ripple and the effective value can be calculated according to the actual needs via professional algorithm. Combined with the waveform export function, various parameters such as the ripple frequency component can be further analyzed.

 

Time measurement

Within the predetermined load conditions and parameter ranges, N6140 will record the time point of two triggers by setting two values or some event (such as Vmax) as the trigger source. N6140 will then calculate the interval between two triggers.

 

Powerful automatic test     

The automatic test can rapidly obtain various parameters. No manual intervention is required after the test procedures and parameters are set in advance. In this way, the efficiency of the production line can be greatly improved and large-scale automation integration can be achieved.
