Tested good about 1.5 years ago and has been sitting on a shelf since then. I no longer have a mainframe to test it again so it's being sold as-is. Includes case and all the accessories. TEK SD14 Sampling Head Features The SD-14 is a dual-channel, 3 GHz probe sampler designed for high-impedance signal acquisition where a 50 Ohm acquisition system is not the optimal solution. The SD-14 is ideal for high-speed device characterization such as ECL, CMOS, ACL and GaAs testing. The 100 kilohm input impedance and 0.5 pF capacitance results in very low loading of the device under test. The 7 V dynamic range and ±3.5 V offset range, makes the SD-14 suitable for testing all digital logic families as well as most analog circuits. The SD-14 consists of two samplers, each attached at the end of a 1.0 meter cable for easy circuit probing. The modular architecture of the CSA 803C/11801C enables the use of extended samplers, bringing a new level of performance to sampling scopes. In conjunction with the 11801C and SM-11 multi-channel unit, it is possible to configure up to 136 channels of high-impedance, high-bandwidth acquisition with measurement accuracy approaching 140 ps. SD-14 Option 01 adds a longer probe tip, two probe-to-ECB (etched circuit board) adapters, and two probe-to-SMB adapters. These ease probing of plated holes (as found in Outboards for IC testers) and semi-permanent connections. 100 kilohm, 0.5 pF Typical 7 V p-p Dynamic Range 3 GHz Bandwidth ECL, CMOS, ACL GaAs Device Characterization Specifications Acquisition System - SD-14, SD-22, SD-24, SD-26: dual channel; SD-20, SD-32: single channel.
