Information
The SD-20 Sampling Head is a high-performance sampling head
that can be installed in the 11800 Series Digital Sampling
Oscilloscopes, the SM-11 Multi-Channel Unit, and the CSA 803
Series Communications Signal Analyzers.
The SD-20 Sampling Head provides the following features:
■ A one-channel feed thru path for signal acquisition and
measurements.
■ A 17.5 ps acquisition rise time.
■ A 20 GHz typical bandwidth for high-speed signal capture.
■ Displayed noise is 750 |jVRMs typical without smoothing
and 350 |jVRMs typical with smoothing on.
■ Precision 3.5 mm connectors.
■ A SELECT CHANNEL button for quick trace acquisition and
selection from the sampling head front panel.
As shown in Figure 1, the SD-20 Sampling Head has a single
acquisition channel with a feed thru or loop path (labeled
LOOP on the front panel), an INPUT connector, and a FEED
THRU connector (both of these connectors are also located on
the front panel).
The strobe drive signal from the instrument controls the
timing of the strobe assertion to the Acquisition system.
