... input to ground that we showed in Figure 3-71 on page 161. Since these diodes change the receiver’s input impedance from very high to very low for negative voltages, they limit the negative excursion at time T to about 1 V. This reduces the reflection back to the sending end, which in turn reduces t ...

Test probe
A test probe (test lead, test prod, or scope probe) is a physical device used to connect electronic test equipment to a device under test (DUT). They range from very simple, robust devices to complex probes that are sophisticated, expensive, and fragile.
