Tektronix P6241 4.0 Ghz Active Probe,10x 8vpp Dynamic Range
The Tektronix P6241 is a 4.0 GHz, 10X active probe with <0.5 pF input capacitance. The P6241 low input capacitance and high (40 kΩ) input resistance minimize circuit loading over a wide bandwidth range. The small profile and low-mass head of the P6241 make probing dense circuits by hand fast and easy. The accessory tips and adapters included with the probe enable the P6241 to be used on a wide variety of circuit architectures.
The P6241 is powered through a TEKPROBE interface between the probe compensation box and the host instrument. The P6241 can be used with non TEKPROBE host instruments by using the optional Tektronix 1103 Probe Power Supply.

Features and Accessories
Probe head assembly.
The probe head is designed for ease of use and high performance. The small size makes it easy to handle in tight areas.
The probe head features a slot that is designed for holding accessories in place.
TEKPROBE interface.
The TEKPROBE interface provides a communication path between the probe and the host instrument. Contact pins provide power, signal, offset, and probe characteristic data transfer.
If your host instrument does not support the TEKPROBE interface, you can use the optional 1103 probe power supply as an effective interface. Contact your local Tektronix representa- tive for more information.
Short ground pogo pin.
This pogo ground pin has a flexible reach of .070 to 1.00 inches, and a .083 inch nominal center space. The pin retracts when pressure is applied.
When a short ground is required for probing, insert the pogo pin into the ground socket of the probe or adapter.
When selecting the grounding connection, maintain as short a ground path as possible.
Z lead.
Use the Z lead to ground the probe when the distance between the DUT test point and ground is greater or less than about 0.100 in. (the fixed distance between the probe tip and probe ground).
You can rotate the Z-lead in the probe ground socket to accomodate distances of approximately 0.020 to 0.180 in.
Three-inch ground lead.
Use the three-inch ground lead for general probing. The socketed end of the lead may be connected to any of the probe tips and adapters or fitted onto 0.025 inch square pins.
To attach the ground lead, press and rotate the lead pin connector into the ground socket on the probe head. The lead may be removed by pulling the pin out by hand.
When selecting the grounding connection, maintain as short a ground path as possible.
Customizable ground lead.
This ground lead wire can be bent or cut shorter.
NOTE: To ease insertion into the ground socket of the probe, cut the tip of this ground lead wire at a 30 to 60 degree angle.
To maintain signal fidelity while probing, use as short a ground path as possible. Refer to page 27 for more grounding information.
This accessory is not intended for use with the Square-pin adapter.
Square-pin adapter.
This adapter has a socket for holding a square pin, or an adapter such as the SureToe, SMT KlipChip, and Y-lead adapters. A square-pin ground socket extension that you insert into the ground socket of the probe is included. These sockets can accept 0.100 inch or 0.080 inch centered square pins.
To attach the square-pin adapter, hold it between your thumb and forefinger, and gently slip it over the probe head until the accessory slot on the probe head holds the adapter in place.
L-adapter.
This adapter enables you to probe and ground at right angles to the device under test (DUT), while holding the probe parallel to the DUT. A ground socket extension that you insert into the ground socket of the probe is included.
To attach the L-adapter, hold it between your thumb and forefinger and gently slip it over the probe head until the accessory slot on the probe head holds the adapter in place.
Removing the Square-pin and L-Adapters.
Caution! The Square-pin and L-adapters have a tab on the bottom side of the probe. (See illustration). When you remove these adapters, do not bend the tab, otherwise you will break the tab.
To safely disengage the adapter from the probe tip, grasp the sides of the adapter (not the tab), and gently rock the adapter side-to-side as you pull the adapter straight off of the probe.
Functional Check
After installing the probe on the host instrument, a functional check may be performed using the PROBE COMPENSATION connections on the front panel of the host instrument. Before you can connect the probe to the PROBE COMPENSATION on the host instrument, you must first attach the square-pin and Y-lead adapters and SMT KlipChips to the probe
P6241 Functional Check Setup
- Hold the square-pin adapter between your thumb and forefinger and gently slip it over the probe head until the accessory slot on the probe head holds the adapter in place.
- Gently press the lead pins from the Y-lead adapter into the signal and ground sockets of the square-pin adapter.
- Plug the KlipChips into the Y-lead adapter.
