Multiple configurations for functional circuit testing

DCQ

The multicontact DC Quadrant probe provides user-configured flexibility in a single probe head. The DCQ uses microstrip ceramic blade probes suited for applications that require a controlled impedance environment where the signal path connects directly to an insulated wire, coaxial cable, or other transmission line. This probe style, consisting of a cantilevered tungsten or beryllium copper wire probe attached to a ceramic blade, offers superior mechanical stability and enables the placement of high quality bypass capacitors within close proximity to the probe tip, minimizing series inductance. All ceramic blades are connected to a common ground plane but individual probes can be easily isolated for additional low noise performance.

DCQ Features and Benefits

• Accommodates 16 DC
• Supports ground, power, or logic applications
• Flat tip DC probes available in 3 tip diameter sizes
• Each DC probe ceramic blade supports a maximum of 3 components
• Optional user-defined cable and connector interface
• Accommodates uniform or staggered arrays (x, y, and z directions)

WPH

The multicontact WPH probe series is designed for applications not requiring a controlled impedance environment. The WPH probe uses standard ceramic blade probes connected directly to a printed circuit board (PCB). This probe style, consisting of a cantilevered tungsten wire attached to a ceramic blade, has a full radius tip (0.0010” diameter). The PCB was designed to accommodate the addition of both series and shunt components to the signal path of each probe. A cable interface (2 x 13 square-pin header) is directly mounted to the PCB.

WPH Features and Benefits

• Accommodates 12 DC
• Tip shape produces narrow scrub marks and breaks through oxide surfaces with minimal flaking
• Double row header supports standard .100” on center cable interfaces
• Accommodates uniform or staggered arrays
• Optional SMD components can be mounted directly to PCB Economical alternative for non high-speed applications
