Description
Overview
The Tektronix P7380SMA is an 8 GHz differential SMA probe designed for measuring high-speed differential signals in 50 Ω signaling environments. It converts differential SMA signal paths to single oscilloscope input channels, enabling simultaneous acquisition of multiple high-speed differential signals across multiple oscilloscope channels.
Key Features
- >8.0 GHz bandwidth (typical)
- 50 Ω termination network with differential SMA inputs
- Industry-leading differential return loss and VSWR performance
- High-bandwidth differential amplifier with excellent CMRR
- Internal termination voltage generator controlled by oscilloscope, external source, or automatic probe sensing
- Phase-matched SMA cables (38 inch length, <1 ps skew) with cable loss compensation
- Switchable gain for extended dynamic range
- Auxiliary (inverted) output for spectrum analyzers, network analyzers, and clock recovery
- TekConnect interface for oscilloscope control and usability
Applications
- High-speed serial data standard testing
- Multi-lane differential signal measurement
- Compliance testing at high frequencies
- HDMI and DVI differential standard testing
