P6243 Instructions

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 and low-mass that makes
probing crowded circuits fast and easy. The accessory tips and
adapters allow for a wide variety of circuit 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 part numbers of standard and
optional accessories, refer to the

P6243 Service Manual

(070-9409-XX).
