The Tektronix 2432 is a 300 MHz, 100 MS/s dual-channel portable digital scope. It does not appear in any (?) Tektronix Catalogs. The 2432 came with two P6136 probes and the standard accessories.

Its successor, the 2432A introduced in 1989, has an increased sampling rate of 250 MS/s. The 2432M was introduced in 1989 and offers Control Intermediate Interface Language (CIIL) capability for operation in Modular Automatic Test Equipment (MATE) used in testing military avionics and weapons systems.

WARNING: Operation of the 2440, 2440M, 2439, 2432, 2432A, 2432M, 2431L, 2430, 2430A, 2430M and 2424L: The A/D-converter and CCD hybrids may suffer irreparable damage within a few minutes if operated out of the metal enclosure without extra cooling.
