    Tektronix SD22 Sampling Head
  • 12.5 GHz bandwidth
  • Dual-Channel
  • 20 ps acquisition rise time (28 ps ??)
  • 450 μV RMS of displayed noise (typically)
    Compatible with CSA803A and 11801

    The SD22 is a dual-channel, 12.5 GHz sampling head specifically designed for low-noise measurement in digital communications and device characterization applications. It provides an acquisition rise time of 28 ps, and typically 450 ÁVRMS of displayed noise. With smoothing, noise levels are 180 ÁVRMS.

    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 SD22 is the ideal instrument for these low-noise applications.
