DESCRIPTION

The Berkeley Nucleonic's Model GL-3 is a general purpose sliding pulse and ramp generator with a broad operating range. It offers a quick, convenient way to measure linearity. By using pulses whose amplitude linearly increases and decreases in time, you can sweep through the entire range of your system. With the high repetition rates, you can accumulate quickly a statistically sufficient number of counts.
