Vector Network Analyzers (VNA)
ME7838 Series VectorStar Broadband VNA
The Anritsu VectorStar ME7838 broadband series system provides high performance in a compact mmWave module utilizing the Anritsu Nonlinear Transmission Line (NLTL) technology, with system coverage from 70 kHz to 110, 125, 145, and 220 GHz. The ME7838 series is the only broadband system with positive raw directivity in multiple bands. The result is better calibration and measurement stability with significantly longer time between calibrations for accurate measurements and improved productivity.
Key Features
- The ME7838AX or ME7838EX version can easily be upgraded to 145 GHz and to 220 GHz
- All versions may be configured to include banded millimeter-wave modules up to 1.1 THz
- Industry-best calibration and measurement stability: 0.1 dB vs 0.6 dB over 24 hrs.
- All versions support the 3744x-Rx receiver for noise figure measurements, including the ability to characterize differential noise figure, to 125 GHz
- Compact, lightweight mmWave modules (0.6 lb vs 7+ lbs and 1/50 the volume) offer low cost installation on smaller probe stations
