Tektronix SD-24 TDR/Sampling Head The SD-24 TDR/Sampling Head is a high performance sampling head that can be installed in the 11800 Series Digital Sampling Oscilloscopes, the SM11 Multi Channel Unit, and the CSA 803 Series Communications Signal Analyzers. The SD-24 TDR/Sampling Head provides the following features: · Two independent channels with signal acquisition and step generator capabilities. In addition to signal sampling, the two channels let you perform differential and common mode TDR and TDT measurements. · Both step generators have switchable polarity, with 250 mV amplitude. · A 28 s typical displayed TDR incident rise time and a 17.5 ps or less acquisition rise time. The reflected rise time is 35 ps or less. · A 20 GHz typical bandwidth provides high-speed signal capture. · Displayed noise is 750 µVRMS typical without smoothing and 350 µV typical with smoothing on. Older sampling heads have a different noise specification. · Precision 3.5 mm connectors. · A Channel Select button for quick trace acquisition and selection from the sampling head front panel. The SD-24 has two independent channels; each has its own acquisition and step generation circuitry. The strobe dive signal from the mainframe controls the timing of the strobe assertion to each acquisition system. The strobe generator in the sampling head is common to both channels, guaranteeing sampling coincidence between the two channels. I am selling 3 units individually. NOT a set. Just showing pictures of all 3 so you can see exactly what you are getting. Manufactured by Tektronix, Inc. Beaverton, Oregon, USA ©Tektronix, Inc. 1988, 1993.
