Tektronix’ brings you the first-available

high-speed differential SMA input probe.

The P7350SMA provides a tool for meas-

uring differential signals in a 50 Ω sig-

naling environment. Before the introduction

of the P7350SMA, most serial data com-

pliance 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 differ-

ential 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 chan-

nels, 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 applica-

tions, such as AC-coupled and some DC-

coupled 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, imple-

mented 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.
