What is the basic difference between a digital-test instrument and a digital-word generator?
The main difference is flexibility. A digital-word generator releases batched data at a fixed rate, meaning that the data coming from the instrument can only change at the selected frequency. A performance digital-test instrument has greater flexible timing, which allows the programmer to delay data from the programmed edge and format data. The use of phase generators creates finer control over signal activity and allows the user to create timing sets that accurately reflect “data book” timing for bus structured devices.
