Tektronix’ brings you the first-available
high-speed differential SMA input probe.
The P7350SMA provides a tool for meas­uring differential signals in a 50 Ω sig-
naling environment. Before the introduction
of the P7350SMA, most serial data com­pliance measurements required cabling a
differential signal to two oscilloscope
channels and applying waveform math to
calculate the difference. By integrating a
dual 50 Ω termination network and a differ­ential amplifier in the probe head, the
P7350SMA measures a differential signal
pair on each

channel of a multiple channel
oscilloscope. Since many of the new
high-speed serial data standards define
differential signaling on multiple chan­nels, the P7350SMA provides a more
efficient measurement solution.

The P7350SMA probe architecture includes
an input termination network, a differential
buffer amplifier, and a common mode DC
bias port. Since many differential data signals
operate with a non-zero DC common mode
voltage, the DC bias port allows for more
flexible interfacing to these logic families.
For applications requiring a common mode

DC termination voltage, that voltage can be
supplied to the P7350SMA DC bias port
through a standard banana plug connector.
For other differential measurement applica­tions, such as AC-coupled and some DC­coupled high frequency 8B/10B encoded
data streams, the DC bias port can simply
be left unconnected.

Input signals use SMA connectors to attach
to the input termination network, imple­mented on a laser-trimmed hybrid circuit
for signal fidelity and high frequency
responses. The linear buffer amplifier
converts the differential input
signal to a single-ended output and drives
the output signal down the probe cable
at full bandwidth.

An active differential buffer amplifier in
the probe head enables the P7350SMA
probe to move the measurement interface
from the oscilloscope front panel to the
circuit-under-test. This can reduce the
length of electrical interconnect cabling,
which for multi-gigabit data signals also
reduces frequency dependent loss
distortion in signal measurements.
