Sampling of products from the past year
Thermometer uses multiple probe types
The Models 1523 and 1524 reference thermometers from Fluke’s Hart Scientific division bring laboratory-quality measurements to the field through RTD (resistance temperature detector), thermocouple, and thermistor probes. The single-channel 1523 and dual-channel 1524 feature an accuracy of ±0.002%, and they will hold that accuracy over an ambient temperature range of –10°C to 60°C. The thermometers can log data that you can download to a computer, and they also plot data and perform statistical analysis on temperature data. Fluke, www.fluke.com.
Card injects errors onto the PCI bus
Agilent Technologies’ N5323A PCIe (PCI Express) Jammer card lets you test a peripheral card or PC motherboard by injecting errors onto the bus. You can inject errors at the physical layer, data-link layer, and transaction layer. Physical-layer errors include disparity error, drop of TLP (transaction-layer packet) start and end characters, and link retraining. Data-link errors include dropping or inserting DLLPs (data-link-layer packets) and sending corrupt CRC (cyclic redundancy code) values. Transaction-layer errors include dropping, delaying, replacing, or modifying TLP packets. Agilent Technologies, www.agilent.com.
Spectrum analyzer combines technologies
The Tektronix RSA6000 spectrum analyzers with Option 200 combine Tek’s real-time spectrum analysis with the DPX (digital phosphor display) technology that the company developed for oscilloscopes. The real-time spectrum analyzers capture signals in the time domain, then transform the data into the frequency domain.
The Swept DPX technology lets the RSA6000 combine the transform technology with the more traditional frequency sweep. The instrument captures signals in 110-MHz frequency bands and then assembles the bands together to produce a frequency plot of up to 14 GHz. The RSA6000 also adds a DPX Density Trigger feature that lets you trigger the instrument on the frequency of a spectral occurrence. Tektronix, www.tektronix.com.
Oscilloscopes reach 30 GHz
LeCroy’s WaveMaster 8 Zi oscilloscopes and SDA 8 Zi serial data analyzers are the first real-time oscilloscopes to offer a bandwidth of 30 GHz. Both lines consist of eight models, with bandwidths starting at 4 GHz. All models are upgradeable to higher bandwidths as your needs change. You can use the 8 Zi series with high-speed, 50-Ω active probes or with 50-Ω and 1-MΩ passive probes without adapters because the instruments provide connectors for all probes. The high-frequency connectors for the 20-GHz to 30-GHz models are microwave grade. LeCroy, www.lecroy.com.
Instrument simulates batteries and chargers
Keithley Instruments’ Model 2308, which simulates batteries and chargers for portable devices, lets you test and characterize battery-operated devices for their power consumption. The two-channel instrument can source voltage and sink current on either channel. The ability to sink current lets the 2308 simulate a discharged battery. The built-in DMM (digital multimeter) measures load current on pulses as short as 50 µs. The instrument has an analog voltage output that is proportional to the load current of the device under test so the current waveform can be characterized with an oscilloscope.

Digitizer cards work in wide-ranging applications
The Razor series of PCI digitizer cards from GaGe provide two or four channels with 16-bit resolution and sampling speeds of 100 Msamples/s or 200 Msamples/s. The series consists of four models based on number of channels and sample rate. The 200-Msamples/s models feature 125-MHz analog bandwidth, while the 100-Msamples/s models have 65-MHz bandwidth. All models have separate ADCs (analog-to-digital converters) for each channel. They can trigger from an internal or external clock and store 128 Msamples of data (options up to 2 Gsamples).

Software gains wireless and FPGA features
NI’s LabView 8.6 lets you make remote measurements using a WiFi connection to data-acquisition devices. It also works with Bluetooth, GPRS, and GSM. Version 8.6 lets you download drivers for numerous proprietary wireless sensor networks, and it also adds development and integration features for FPGAs (field-programmable gate arrays). You get more than 1200 data-analysis functions optimized for multicore processors.
You can convert LabView applications into Web services that run on processors that run HTML, Java, or Flash. Users can then gain access to applications through any Web-enabled device. National Instruments, www.ni.com.
