Most 7000 series plugins have rings around the BNC input sockets that allow attached probes to interface with the readout system. The probe connector includes a contact pin connecting this ring. A resistor connected to ground encodes the probe attenuation, e.g. 11 kΩ indicates a ×10 probe and 6.8 kΩ a ×100 probe. If the probe includes an Identify switch at the tip, this connects the readout pin directly to ground. The [[Media:Tek-plugin-readout.jpg|plug-in circuit]] uses the shift instructions in time slot 1 to implement the change of range. | Most 7000 series plugins have [[BNC connector with readout ring|rings around the BNC input sockets]] that allow attached probes to interface with the readout system.
