The Tektronix SD-20 Loopthrough Sampling Head is a single-channel, 20 GHz loop-through sampling head designed for low-loss testing in applications such as microwave systems research and development, digital device characterization and high-speed digital communications circuit design.
Like the older S-6, the SD-20 is non-terminated and routes the signal of interest directly through the sampling head without the need of a power divider, thus keeping losses to a minimum. The SD-20 can also be used for customized TDR measurements of transmission lines and controlled impedance devices. An external signal generator may be used, instead of the SD-24 step generator, to tailor the TDR stimulus to fit a particular situation. For instance, slower slew rates or higher amplitude may be utilized, or one may perform half-sine or impulse testing. In digital communications, the SD-20 is useful for viewing and triggering on the clock signal without the use of a power divider.
