Differential SMA Probe to 8 GHz Differential SMA probes are designed for measuring differential signals in a 50 ohms signaling environment, providing the ability to convert from a differential SMA signal path to a single oscilloscope input channel. The Tektronix Differential SMA Probes provide the ability to measure a high-speed differential signal on each channel of a multiple-channel oscilloscope. The right oscilloscope can simultaneously acquire up to four high-speed differential signals with the use of four differential SMA probes. As an added benefit, the SMA inputs on the probes connect to high-quality 50 ohms terminations that offer industry-leading return loss. >8.0 GHz Bandwidth 50 ohms termination network, differential SMA inputs Industry-leading differential return loss and VSWR High-bandwidth differential amplifier with excellent CMRR Internal termination voltage generator can be controlled internally by the oscilloscope, by an external source, or automatically by the probe Phase-matched SMA cables (38 inch length, <1 ps skew) with cable loss compensation Switchable gain for extended dynamic range Auxiliary (Inverted) output for use with spectrum analyzers, network analyzers, or as a clock recovery trigger source TekConnect interface Bandwidth: 8 GHz Attenuation: 2.5X, 12.5X, user selectable Differential input range: 0.625 Vp-p (2.5X), 3.0 Vp-p (12.5X) Noise, referred to input: <13 nV/√Hz (2.5X), <40 nV/√Hz (12.5X) CMRR: >50 dB to 100 MHz >35 dB to 1 GHz >20 dB to 5 GHz >15 dB to 8 GHz Applications: Validation and compliance testing of serial data standards including: Express I and II Serial ATA FBDIMM DDR XAUI
