Accurate power analyser has wide frequency range
Precision power analyser that combines an exceptionally high accuracy with a wide frequency range can carry out up to four power measurements simultaneously.
Software aids IC engine pressure analysis
IC engine software package allows analysis and display of multiple data simultaneously, so that results can be checked simultaneously with online monitoring.
The VN7100 is a single-box solution integrating an RF down-convertor, digitiser and computer in a compact, lightweight package measuring 426 ? 176 ? 450 mm and weighing 19 kg.
A 12-bit, 210 MS/s A/D convertor enables fast, high-resolution measurements, while the long memory (1 Gbyte SRAM with 128 M points per channel) makes it possible to measure for long periods or - by dividing up the acquisition memory - to carry out measurement and analysis operations simultaneously.
Measurements carried out by the VN7100 include time-domain analysis, frequency-domain analysis, statistical analysis (including CCDF power measurements) and I/Q output (demodulation) analysis.
Up to four measurements - including eye-diagram and constellation plots - can be displayed at once.
The instrument uses FFT (Fast Fourier Transform) techniques which offer a number of benefits over the traditional swept-oscillator approach: in particular, the ability to view spectrum and modulation simultaneously as well as carrying out re-calculation or analysis of data stored in the memory.
Optional software is available for WLAN analysis and testing compliance to the IEEE 802.11a/b/g standard, including EVM and continuous BER (bit error rate) measurements.
