WaveLink Probe System

Unprecedented flexibility for probe interconnection

WaveLink probes provide industry leading technology for wideband signal connection to test instruments. The first differential probes to employ SiGe technology, they deliver full system bandwidth when used with LeCroy 6 GHz, 5 GHz, and 3 GHz instruments. 

While other probes have higher DC resistance, their loading impedance quickly drops to very low values at relatively low frequencies. Most cross below the WaveLink impedance at only 200 MHz. WaveLink probes:

• Use transmission line topology in the input section combined with
  active differential probe technology

• Maintain essentially constant input loading from DC to several GHz

Very Accurate Eye Pattern Measurements

WaveLink probes virtually eliminate distortion when measuring signals. This
benefit is particularly useful in eye pattern measurements, now routine for
systems using fast serial parallel data bus architecture.
All WaveLink probes offer:

• Superior loading characteristics

• Precise frequency response with outstanding fidelity for high-speed signals

Both low loading and frequency response flatness are needed to ensure the signal fidelity required to measure performance accurately.

3.125 Gb/s XUAI signal measured with system using a probe
with good frequency flatness, but excessive loading.

Same signal measured with WaveLink D600A-AT. Low loading
and flat frequency response combine to maintain the fidelity in
the eye pattern.

D500PT Positioner Mounted Probe Tip Module

The probe has a very thin form factor, allowing multiple probes to be used when several channels are required to monitor signals from the same small IC. It has 2 mm of Z-axis compliance through spring-loaded telescoping tips, allowing considerable angular freedom relative to the circuit board while still maintaining reliable contact with both inputs. A ball joint between the tip and mounting arm makes it even easier to adjust for placement when already mounted in a positioner. A small thumbscrew allows precise and secure adjustment of the tip spacing.

The Positioner Mounted Module, D500PT, can be used as a browser in a positioner such as Easy Probe. Because of its thin form factor and spring-loaded tips, it is ideally suited for use with multiple probes in tight areas, such as the back side of boards with ball-grid array packaged ICs.

The WaveLink Differential Probe Series are high bandwidth
active differential probes. These probes are suited for signal
integrity measurements in high-speed digital systems.

The Probe Tip Modules contain the active amplifier circuitry.
Different modules have different electrical and physical
interconnect characteristics, allowing the user to select the
module appropriate for the application.

D600A-AT & D300A-AT Adjustable Tips

WaveLink adjustable tip probes are designed to provide an optimum mechanical connection for signal measurement. • Built-in thumbwheel for precise positioning of tip—stays put after adjustment • Maintains sharp points for good contact • Tips made of “NiTiNOL,” a super-elastic nickel-titanium alloy • Flexes as you apply pressure • Consistently returns to original form

EZ-Probe Positioner

The EZ-Probe positioner provides stable, accurate positioning in the x-y-z axis. Ideal for use with the D500PT and D600A-AT / D300A-AT probe tips. The unique, 3:1 motion reduction joystick allows simple, precise positioning of the attached probe in both the horizontal and vertical measuring plane. The probe has a fully articulating arm, providing 30 cm (12") reach in virtually any direction.

WaveLink D600ST and D350ST

Best-in-class mechanical design for optimum utility:

• Small tip, high bandwidth differential probe
• Three interconnect configurations for flexibility
• Very small form factor for accessing tight spaces

Each of the interchangeable leads is a thin, highly flexible 145 mm (5.7")
long lead connecting the tip and the D600ST/D350ST probe tip module.

Three Different Tips for Interconnect Flexibility

A. Solder-In Lead
The Solder-In interconnect lead features the smallest physical tip size
of any high bandwidth differential probe and the highest level of electrical
performance. Two very small damping resistors are directly soldered into the connect points providing a reliable, intermittence-free electrical connection. The resistors have highly flexible leads allowing connection to input points with a wide range of input spacing.

B. Quick Connect (D600ST only)
The Quick Connect interconnect lead enables you to quickly move the probe between multiple test points on the test circuit. Just solder a pair of
damping resistors at each location where interconnection is required.
A small connector mounted on the probe tip plugs into the damping
resistors, letting you quickly move between sets of test points.

C. Square Pin
Many applications, such as IC characterization boards, use standard 0.025" square pins for interconnect. The Square Pin interconnect lead directly mates with a pair of 0.025" (0.635 mm) square pins that are mounted on standard 0.100" (2.54 mm) centers.
