Agilent Technologies has added bit error ratio capabilities to its optical modulation analyzer. The BER analysis of a transmitter or link is the critical parameter in measuring the transmission quality of 40 G/100 G systems. The company has integrated into the analyzer a receiver that counts the errors and calculates the BER from detected data in real time or in large sample number capture mode. The test signal can be either a pseudo-random-bit sequence or a user-defined pattern. Measuring only the electrical BER from an optical link’s transmitter input to receiver output leaves uncertain which of the three components—the transmitter, the link itself, or the receiver—caused the BER problem during a test failure. Being able to measure the BER of a physical layer signal allows users to clearly distinguish which part of the transmission system caused the fault.

Three new antenna-mounting adaptors from AR RF/Microwave Instrumentation allow horizontal and vertical polarization changes during testing without removing the antenna from the tripod. The adaptors are designed to be compatible with existing AR antenna models—adaptor model AM1000 is for use with antenna models AT1000 and AT1000A; adaptor model AM1001, with antenna models AT1080 and AT1080A; and adaptor model AM6000, with antenna models AT5080 and AT6080. Each adaptor includes a 20-inch nonmetallic mast. Because the center of gravity is offset when moving the antenna between horizontal and vertical polarizations, the company recommends that users purchase a new tripod along with the antenna mount. The model TP1000B tripod features a robust design and a new angle-adjustment mechanism. AR RF/Microwave Instrumentation, 160 School House Road, Souderton, PA 18964-9990,

Data Translation has announced the DT8837 high-performance Ethernet (LXI) data acquisition instrument module for sound and vibration measurement applications. The transmission control protocol/internet protocol Ethernet operation mode of the DT8837 allows measurements to be monitored locally or remotely. Up to 16 instrument modules may be stacked for parallel operation of 64 separate integrated electronics piezoelectric accelerometer or voltage inputs. Each of the separate synchronized modules can also be triggered externally in various ways. ISO-channel technology uses galvanic isolation methods to guarantee 1000-V isolation between any two input channels and ± 500 V to earth ground. ISO-channel increases reliability by implementing unique isolation mechanisms for each 24-bit A/D converter in the four input channels and on the 24-bit stimulus D/A output channel, all operating in parallel. The benefit to users is total isolation of all inputs and outputs from each other and from digital ground. Data Translation Inc, 100 Locke Drive, Marlboro, MA 01752-1192,

Veeco Instruments has introduced its NPFlex 3D metrology system for characterizing surfaces previously too difficult to measure because of size or part orientation. The NPFlex combines non-contact, white-light optical profilers with an open-access design to enable rapid, 3D data acquisition and analysis on a wide range of large samples for precision machining applications in the medical implant, aerospace, and automotive market sectors. It uses a gantry design to provide more than 300 degrees of access for large samples. The optional swiveling optical head permits routine investigation of highly curved samples and beveled edges. The system’s white-light interferometric technology provides greater accuracy, repeatability, and, importantly, data density than is possible with contact instrumentation.

Omega Engineering has introduced the OM-EL-USB-2-LCD, a standalone data logger that can measure and store up to 16 379 temperature readings over a range of −35 °C to 80 °C and the same number of relative humidity readings over a range of 0-100% RH. It also provides dew-point indication using the included Windows control software. A high-contrast 2 1 2 digit LCD offers cycling between the current temperature and humidity and the maximum and minimum stored values for each. Two high-intensity LEDs show logging and alarm status. The data logger is supplied with a long-life lithium battery that typically allows logging for up to one year. Data are downloaded by plugging the unit into a PC’s USB port. A data-rollover function overwrites the oldest data when the memory is full, allowing for unlimited logging periods. Downloaded temperature, humidity, and dew-point data saved in text format can be graphed, printed, and exported to other applications for further analysis.

IntelliCal is a spectrograph calibration routine from Princeton Instruments now available as an add-on to Light-Field, the company’s new 64-bit data acquisition software package. Unlike traditional calibration methods that rely on a few mercury emission lines, IntelliCal refines the spectrograph parameters to match observed and calculated emission spectra in intensity space. The result is in an order-of-magnitude increase in wavelength accuracy with a greatly reduced need for user input. IntelliCal reports the root-mean-square wavelength error at each pixel of an array detector and stores the calibration information in the file header, giving users confidence in their results. Once a spectrograph has been calibrated, a one-click search-match algorithm identifies the current center wavelength position without the need for a new refinement cycle. Spectral tables from NIST are used for the highest possible accuracy. Princeton Instruments, 3660 Quaker-bridge Road, Trenton, NJ 08619,

LeCroy Corp is expanding its WaveAce oscilloscope line to include four-channel models from 60 to 300 MHz and adding a new two-channel, 40-MHz model. The four-channel models provide 10 kpts/ch of memory and a sample rate up to 2-GS/s; the 40-MHz model has 4 kpts/ch of memory and a sample rate of up to 500 MS/s. All models offer long memory, color displays, extensive measurement capabilities, and advanced triggering to improve troubleshooting and shorten debugging time. With USB host and device ports and a LAN connection, the WaveAce oscilloscopes connect to a memory stick, PC, or printer for data saving or remote control. Combined with the streamlined, time-saving user interface, the features make the WaveAce oscilloscopes suitable tools for designing, debugging, and troubleshooting from 40 to 300 MHz. Additional features include pass/fail testing, user-definable digital filters, and a waveform sequence recorder. LeCroy Corporation, 700 Chestnut Ridge Road, Chestnut Ridge, NY 10977-6499,
