This paper describes a fully programmable, VME based, eight channel, a
rbitrary waveform generator, specially adequate for the control of ope
ration of high temporal resolution diagnostics of nuclear physics expe
riments. Each channel is built around an 1 Mega-sample-per-second, 12
bit, digital-to-analog converter and it is provided with 8 kWords of F
IFO memory allowing operation in a free running mode. The main operati
onal features of this module are described. Methods for assessing its
performance are discussed and the test results are presented. Applicat
ion of this multiple waveform generator on the operation of two diagno
stics of the tokamak ISTTOK is referred.
