The RTPA2A Real-time Probe Adapter extends the capabilities of Real-time Spectrum Analyzers (RTSA) by offering additional tools to make debugging today’s high-performance electrical designs easier. Using the RTPA2A with Tektronix RTSA, design engineers can benefit from industry-leading Tektronix active and differential probes to measure signals on SMD pins and other challenging circuit features.

Notice to EU customers

This product is not updated to comply with the RoHS 2 Directive 2011/65/EU and will not be shipped to the EU. Customers may be able to purchase products from inventory that were placed on the EU market prior to July 22, 2017 until supplies are depleted.

Tektronix will continue service to the end of worldwide support life.

Key features
  • Interface Tektronix P7000 series high-performance active and differential probes to Tektronix real-time spectrum analyzers
  • Seamless Integration
    • Automatically scales measurement for probe attenuation setting
    • Simplifies setup for troubleshooting, eliminates possible setup errors, requires no user adjustment
  • Extends the troubleshooting capabilities of Tektronix real-time spectrum analyzers with the world’s best probes
  • Troubleshoot and determine RF faults directly on circuit boards where no coaxial connection is available
  • Use differential probes for high-impedance IQ baseband applications
  • General RF troubleshooting – find sources of circuit interference
  • EMI troubleshooting – help identify components and circuits causing EMI problems
  • High-speed digital design – high dynamic range phase noise measurements
  • High-impedance IQ baseband input for low-power RF devices

TekConnect® probe adapter for real-time spectrum analyzers

The RTPA2A provides probe power for up to two Tektronix P7000 Series probes through an external power supply. Probe control signals are handled through a USB cable that connects the RTPA2A to the RTSA. This allows the RTSA to automatically adjust the scale factor to account for attenuation factor of the probe in channel A. The included SMA-to-N cable allows the high-speed RF signal to travel between the RTPA2A and the RTSA.

Tektronix high-performance probing solutions

Tektronix offers a variety of industry-leading active and differential probes. Tektronix high-performance probes feature small probe heads and numerous adapters to provide a flexible and reliable connection to the Device Under Test (DUT).
