Product Description
Tektronix SD-22 12.5 GHz Digital Sampling Head
Tektronix SD-22 12.5 GHz Digital Sampling Head
Tektronix SD-22 12.5 GHz Digital Sampling Head
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 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 SD22 is the ideal instrument for these low-noise applications.
