P7240 4 GHz 5X Active Probe User Manual

When the probe is connected, the oscilloscope reads EEPROM
information from the probe, identifying the device and allowing the
appropriate power supplies to be powered on. The preamp inputs on
the oscilloscope are electrostatic discharge protected by remaining
grounded until a valid TekConnect device is detected.

Installation

The TekConnect interface features a spring-loaded latch that
provides audible and tactile confirmation that a reliable connection
has been made to the oscilloscope. Slide the probe into the
TekConnect receptacle on the oscilloscope. The probe snaps into the
oscilloscope when fully engaged. See Figure 2.

To release the probe from the oscilloscope, grasp the compensation
box, depress the latch button, and pull out the probe.
