20GHz probes improve access to tight test locations

Efficient test and debug of the latest standards from LPDDR4 to MIPI D-PHY and C-PHY requires probes that minimise signal loss to cope with the challenging combination of high-performance and low power.

Unlike other probe designs that use long tip cables connected to a remote amplifier, the P7700 Series probes introduce a breakthrough new design where the probe’s input amplifier is located <4mm from the connection point, minimising signal loss, probe tip capacitance and noise.

Another major challenge is gaining access to signals on increasingly smaller devices. Connections to high speed signals often require engineers to attach probe tips by soldering to a small component or feature on a circuit board.

As the size of these features shrink, they become more fragile and attaching a probe tip can add stress to the component or the circuit board. In addition, multiple probe connections are often required to capture signals on multiple lanes of a MIPI bus or for LPDDR memory, the data, strobe, and clock signals.

The P7700 series probes use compact solder tips that fit into tight spots to minimize the impact on the small size components on the board.

Adding to their versatility, the P7700 series probes introduce the new TekFlex connector that supports a wide range of accessories.

The TekFlex connector and accessories are designed to be easy to attach and at the same time provide the user with a reliable, secure connection including a small LED that lights up to confirm connectivity from the scope to the accessory tip.

Every P7700 series probe comes standard with low-cost solder tips.

These tips support full bandwidth performance for the probes and their low replacement price helps to reduce the cost of probe ownership.

The P7700 TriMode probes complement Tektronix performance oscilloscopes and Tektronix’ powerful validation and debug tools for LPDDR memory, MIPI mobile standards and high-speed serial standards such as USB 3.1 and PCI Express.
