Model 8500 is a modern-universal source of test stimulus waveform. Its flexibility ensures continuing usefulness for a variety of tasks, today as well as in the future, when demands change. Its versatility, reliability, programmability and economy make it equally-at home in engineering research laboratories, production test stand, automated system or in the maintenance shop. Although providing wide 70 MHz frequency coverage, and large 32 V amplitude span, this generator is very affordable even for versions incorporating two output channels.
