Unique Features

13.1 Mini-Tester

Due to the architecture of the Hardware in combination with the Software, the PTC04 can be used as a

mixed mode tester (With limited performance).

There are library routines (DLL) available in order to interface with any software language. (C++, Visual

Basic, Lab view, Excel (VBA)…)

13.2 Analogue Vector Generator

A vector space of 512Kbyte allows you to store a huge amount of actions. These actions consist of setting

a level on a channel, waiting a time x, setting the Fast DAC and making samples on an analogue input

(measurement) or a digital comparator. For details, refer to the PSF of the PTC04 chapter Pattern

functions.
