UDP3305S Series Programmable DC Power Supply User Manual The list mode and delayer are equipped with multiple output templates. The purpose is to facilitate users to operate and save time. The following sections describe the parameters of each template. 4.5 List Mode Templates The optional list mode templates include: sine, pulse, ramp, stair up, stair down, stair up down, exponential rise and exponential fall. 1. Sine The Sine waveform is as shown in the figure below.
UDP3305S Series Programmable DC Power Supply User Manual 4. Stair Up The Stair Up waveform is as shown in the figure below. The instrument determines the amplitude of the Ramp according to the maximum and minimum currently set. The total number of points (N) will divide the amplitude into N-1 steps. The time interval (maximum 99999) indicates the duration of each step, and determines the waveform period together with the total number of points. Stair up 5.
UDP3305S Series Programmable DC Power Supply User Manual Exponential rise 8. Exponential Fall The Exponential Fall waveform is as shown in the figure below. The instrument determines the amplitude of the waveform according to the maximum (M) and minimum (N) currently set and determines the waveform period according to the total number of points (P) and the time interval (maximum 99999). The fall index (R) is the independent variable of the fall function, which is an integer from 0 to 10.
