Showing Results for Tektronix SD32

The SD32 is a single-channel, 50 GHz bandwidth sampling head. The SD32 performance is available for any CSA803A/11801B mainframe. The SD32 has measured bandwidth of greater than 50 GHz and calculated rise time less than 7.0 ps. The front-panel connector is female 2.4 mm, and an adapter is provided (011-0157-00; 2.4 mm male to 2.92 mm female) in order to maintain compatibility with SMA connector systems.

The sampling head acquisition system performs the function of a very fast sample and hold circuit for the mainframe instrument. It uses local analog feedback to achieve high accuracy and high throughput for repetitive input signals. For random input signals like those found in eye diagram measurements, accuracy depends on the dot transient response of the sampling head. Dot response can easily be adjusted through the enhanced accuracy menu in the mainframe. The strobe drive signal from the instrument controls the timing of the strobe assertion to the acquisition system. The strobe sense signal is a part of the strobe signal returned to the instrument. The instrument monitors the time duration of the strobe drive/strobe sense loop and adjusts a delay inside the instrument to maintain correct strobe timing.
