Using Calibration to Optimize Performance in Crucial Measurements
Precision Current Pulse Generator
The model 507 precision current pulse generator offers digitally controlled current pulses with currents from 0 to 10 A and pulse widths from 0.1 to 100 ms. Precise current control and time-domain resolution allow for complete characterization of electronic systems. Offered in two, four and eight channels, the generator is suitable for automobile airbag squib testing, industrial fuse breakdown testing and precision laser triggering and driving applications. TTL-sync outputs are ideal for video capture or other related test parameters. Price: $3295 (two channels). Delivery: 30 days (ARO).

VXI RF Power/Volt Meters
The 5730 series RF power/volt meters for measuring power and voltage measurements in VXI configurations have the ability to sample up to 200 readings per second. The units measure power levels from -70 to +44 dBm with a 90 dB dynamic range, measure RF voltage from 10 Hz to 2.5 GHz and cover 10 kHz to 100 GHz when measuring power. The dual-channel meters also allow readings in different units (such as dB and mW) to be displayed simultaneously on different channels. Sensor calibration data, resident in the data adapter, are automatically downloaded to the meter when the sensor is connected, which eliminates the need to re-enter the calibration if a sensor is changed. A zero correction function stores the zero offsets of each range and automatically corrects all subsequent readings.

RF/Microwave Radiation Badge
The model H600A RF/microwave radiation badge is intended to be utinonionizing RF and microwave radiation. Designed to monitor the telecommunications frequency range of 50 MHz to 2.5 GHz, the badge provides real-time power density (mW/cm2) information via its LCD. Measurement modes include a choice of instantaneous or six-minute average. The H600A provides a user-adjustable alarm level setting from 0.2 to 20 mW/cm2 to satisfy diverse environments. The unit carries a two-year warranty. Standard accessories include a carrying case and earphone for high noise environments. Size: 3.70" x 2.75" x 1.10". Weight: 5 oz.

RF Spectrum Analyzer
The model P9116 spectrum analyzer is designed for use in production automatic test equipment systems and covers the frequency range of 100 kHz to 1600 MHz. It is packaged in a 2RU industrial PC chassis and can be operated like any other conventional RF spectrum analyzer when used in conjunction with a VGA monitor and supplied graphical user interface. Since the unit's local oscillator is digitally tuned, the precise number of steps and the span between steps are fully controllable with a resolution of 2 Hz across the entire spectrum. This feature, coupled with the synthesizer step of < 150 ms, makes the unit ideal for test applications where increased production throughput is critical. Absolute level accuracy is +/-0.5 dB over the -120 to +20 dBm amplitude range and frequency accuracy is 0.5 ppm.
