Tektronix sd-22 oscilloscope sampling head for 11801C

Tektronix SD-22 Oscilloscope Sampling Head
This unit has been tested and is in fine working order with a 7 day right of return. The front view is the middle unit in the group picture.
The SD22 provides an acquisition rise time of 28 ps, and typically 450 µVRMS of displayed noise. With smoothing, noise levels are 180 µVRMS.
In order to precisely capture and display the switching characteristics of high-speed communications circuits, to make accurate statistical measurements of signal noise and signal timing jitter, or to obtain stable timing measurements of fast digital ICs, the noise floor of the test equipment must be kept to a minimum.
The Tektronix SD22 is the ideal instrument for these low-noise applications:
* ECL, CMOS and ACL GaAs Device Characterization (SD14)
* General-purpose TDR (SD20)
* Digital Data Communications (SD22)
* Line Impedance and Crosstalk
* Dual Channel Device Characterization (SD26)
* High Bandwidth Communication & Microwave (SD32)
* SONET/SDH Compliance Testing (ORR24)
