THE FOLLOWING SMALL PRODUCTS DID NOT APPEAR IN THE APRIL ISSUE OF TEST & MEASUREMENT WORLD.

Differential Scope Probe

At 5.0 GHz, the P7350 5-GHz differential oscilloscope probe supplies adequate bandwidth to acquire signals at rates of up to 2.5 Gbps. You can use the probe for testing designs incorporating fast serial bus technologies, such as PCI-Express, RapidIO, serial ATA, and SPI/SF15.  The P7350 guarantees a rise time of less than 100 ps and provides typical differential input capacitance of less than 0.3 pF. It works with scopes in the TDS6000, TDS7000, and CSA7000 series. Price: $7995. Tektronix, Beaverton, OR. 800-426-2200; www.tektronix.com.

Test Probes

A family of six oscilloscope test probes lets you hand probe surface-mount device environments where space is limited and test points are difficult to reach. The probes work with standard oscilloscopes through a BNC connection and employ a sharp, spring-loaded tip that minimizes pressure on the DUT.  You can use the probes for applications ranging from low-mass, low-impedance measurements to testing high-power discrete components.

Calibration Procedures

MET/CAL Plus Version 7—a suite of applications that automates the operation and management of your calibration facilities—adds calibration procedures for Tektronix TDS5000, TDS6000, and TDS7000 series oscilloscopes to reduce performance verification time to approximately 60 minutes or less. Version 7 offers more flexible measurement uncertainty methods, powerful searching capabilities, and extended data storage. Price: $1499. Fluke, Everett, WA. 425-347-6100; www.fluke.com.

PXI Chassis

Equipped with an eight-slot backplane, the PXI-1042 PXI chassis achieves precision timing and synchronization with a low-jitter internal reference clock and external clock connectors. It also includes a high-output power supply and integrated cooling in a compact design suitable for both benchtop and rack-mount test and control environments. Base price: $1975. National Instruments, Austin, TX. 800-258-7022; www.ni.com.

Laser Encoder

The RLE fiber-optic laser encoder is an interferometer-based system that provides high-resolution position feedback for applications with single or dual axes and axis lengths of up to 4 m. It operates from a single laser source and uses fiber-optic links to transport the laser beam directly to the axis measuring position. The system produces digital feedback down to 10-nm resolution, as well as a 1-V pk-pk analog output that can be externally interpolated to nanometer levels. An optional real-time compensation system enables the RLE to achieve position accuracy of 1 ppm over a wide range of environmental conditions.

Diode Laser Systems

Operating at wavelengths of 635, 640, 660, and 785 nm, the 56 ICS CleanBeam series of diode laser systems delivers output power ranging from 7 to 35 mW. Standard systems can be modulated to 5 MHz or optionally to 350 MHz. The fully self-contained units are useful for laser-induced fluorescence metrology applications, as well as other applications where compact size, low noise, constant power, high beam quality, and long life are required.
