2430A

The Tektronix 2430A is a rugged, portable 150 MHz digital storage oscilloscope (DSO) designed for a wide range of demanding applications. Featuring a real-time sampling rate of 100 MS/s simultaneously on two channels and an 8-bit vertical resolution, it incorporates advanced acquisition modes such as 2 ns glitch capture (peak detect) and envelope mode, backed by standard GPIB programmability and a military-grade environmental design.
