P6249 4 GHz 5X Active Probe Instruction Manual 11
Configuration
The P6249 provides the oscilloscope with the probe model number,
serial number, and attenuation factor. When connected to an
oscilloscope with a TEKPROBE interface, display readouts are
corrected for the probe attenuation factor, the instrument input is set
to 50 W, and the coupling is set to DC.
CAUTION. Do not attempt to install the P6249 on a non-TEKPROBE
connector. Damage to the probe and connector may result. If your
oscilloscope does not support the TEKPROBE interface, use the
optional Tektronix 1103 Probe Power Supply.
If the P6249 is used with the Tektronix 1103 Probe Power Supply, be
sure to have a 50 W termination at the oscilloscope. Also, set the
oscilloscope channel coupling to DC.
The probe offset control is controlled by the oscilloscope. If the
oscilloscope used does not support the TEKPROBE interface, use the
offset controls on the optional Tektronix 1103 Probe Power Supply.

Probe Offset

The probe offset is adjustable to permit operation within the linear
range of the probe. Using the offset to cancel DC signal components
enables optimal probe performance. See Figure 1 on page 12 for
more information.
NOTE. See your oscilloscope manual for specific instructions on its
operation and offset control.
