Getting Started
The Tektronix P6243 is a 1 GHz, 10X active FET probe with less
than 1 pF input capacitance. The low input capacitance and high
input resistance of the probe minimize circuit loading over a wide
bandwidth. The probe has a small profile a nd low-ma ss that makes
probing crowded circuits fast and easy. The acce ssory tips and
adapters allow for a wide variety of circ uit connections.
The P6243 Active Probe obtains power from the host oscilloscope
through the TEKPROBE interface. For oscilloscopes and
instruments that do not have the TEKPROBE interface, use the
optional Tektronix 1103 Probe Power Supply.
For service information, including pa rt num bers of standard and
optional accessories, refer to the P6243 Service Manual
(070-9409-XX).

The P6243 Active Probe has features and accessories t o ma ke
probing and measurement a simpler task. Please take a moment to
familiarize yourself with t hese items and their uses.
Probe Tip
Socket
Ground
Socket
Probe Head Assembly — The probe head is
designed for ease of use and high performance.
Its small size makes it easy to handle in tight
areas.
The probe tip socket is sized to easily press onto
0.025 inch pins for direct access. The ground
socket provides a short ground path for high
fidelity ground connections.
Push-In Probe Tip
TEKPROBE Interface — The TEKPROBE
interface provides power, signal, and probe
characteristic data transfer.
If your oscilloscope does not support the
TEKPROBE interface, you can use the optional
1103 probe power supply as an effective
interface. Contact your local Tektronix representative for more information.
Push-in Probe Tip — Use the push-in probe tip
for general purpose probing by hand. The tip may
also be used as a temporary test point. See page
14 for more information.
The push-in probe tip may also be used with the
other socketed leads and adapters.
