P7313SMA • P7380SMA Data Sheet
Applications
Tektronix continues to demonstrate its proven leadership in differential
probing with a significant addition to our Differential SMA Probe Family.
Differential SMA probes are designed for measuring differential signals
ina50Ω sign
differential SMA signal path to a single oscilloscope input channel. Many
of today's high-speed serial data standards employ differential signaling
on multiple lanes that are challenging to measure simultaneously on a
single oscilloscope. The Tektronix Differential SMA Probes provide the

ability to measure a high-speed differential s ignal on each channel of a
multipleacquire 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 Ω terminations that offer industry-leading return
loss, a critical specification that is very important in compliance testing as
frequencies increase.
Tektronix Differential SMA Probes also provide a common mode DC voltage
input to the termination network. The termination voltage can be supplied
either ext
there is also an automatic mode that senses the common mode voltage of
the input signal and automatically sets the termination voltage to match.
The P7313SMA has an extended te rmination voltage range that ma kes it
ideal for testing differential standards with high common mode voltages like
HDMI and DVI.
Taken together, the high-speed differential amplifier, superior 50 Ω
