The models in the AV-1010, AV-1011 and AV-1015 series are general-purpose +/-50V and +/-100V pulse generators which, depending on the exact model, can generate pulse widths as narrow as 20 ns or as wide as 10 ms. The AV-1015-B has a lower maximum amplitude (+/-50 Volts), but operates to repetition rates as high as 10 MHz, and duty cycles as high as 25%. The rise and fall times are 10 ns, and the pulse width is variable from 20 ns to 10 ms.
