    Functional description comtec gmbh 3-1 3. Functional description 3.1. Introduction the 7072t has three different modes of operation: • pha: pulse height analysis • sva: sampling voltage analysis • tdc: time-to-digital conversion any channel can be set in any mode of operation independently. All sett...
