Installing the USB Cable and Power Supply Cable
When a USB cable is connected to a Tektronix Real-Time Spectrum Analyzer,
power is enabled to the probe. The USB cable must be attached for the probe
adapter and a spectrum analyzer system to function properly.
Use only the supplied power supply cable and power cord with the TekConnect

Installing the TekConnect Probe
When the probe is connected, the probe adapter reads EEPROM information
from the probe, identifying the device and allowing the appropriate power
supplies to be powered on.
NOTE. It is not necessary to power off the probe adapter when removing or
installing a TekConnect probe.
The TekConnect interface features a spring-loaded latch that provides audible
and tactile confirmation that a reliable connection has been made to the probe
adapter. Slide the probe into the TekConnect receptacle on the probe adapter. The
probe snaps into the receptacle when fully engaged. See Figure 4.
To release the probe from the probe adapter, grasp the compensation box, press
the latch button, and pull out the probe.

only. To correct the amplitude for Channel B, see Table 6. For example, if you
are using a 5X probe on Channel B, manually apply an amplitude offset
of --14 dB.

Reference
This section contains information you may need to take measurements or to
avoid damaging the RTPA2A product.
Avoiding Damage from Electrostatic Discharge or Overvoltage
Circuitry in the TekConnect probe adapter and probe is very susceptible to
damage from electrostatic discharge or from overdrive signals. Be sure to operate
the system only in a static-controlled environment. Be sure to discharge to
ground any electrostatic charge that may be present on the center and outer
connectors of cables before attaching the cables to the system. Be sure to operate
the TekConnect probe adapter and probe only where DC voltage levels are
within the probe limits. Refer to the probe specifications in your probe instruction manual.
