The Tektronix SD22 is a dual-channel, 12.5 GHz sampling head designed for low-noise measurements in digital communications, device characterization, and high-throughput automated test equipment. It delivers a 28 ps acquisition rise time and typically exhibits 450 µVRMS displayed noise, reducible to 180 µVRMS with smoothing enabled. The head integrates with Tektronix 11800 Series Digital Sampling Oscilloscopes and is compatible with the CSA803C, 11801C, 118 Series instruments, SM-11 Multi-Channel Unit, and CSA 803 Series Communications Signal Analyzers.
