Manuals – Specifications – Links – Pictures

The Tektronix 2432 is a 300 MHz, 100 MS/s dual-channel portable digital scope. It does not appear in any (?) Tektronix Catalogs.

Its successor, the 2432A introduced in 1989, has an increased sampling rate of 250 megasamples/s.

WARNING: Operation of the 2440, 2439, 2432, 2432A, 2431L, 2430, 2430A 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.
