Easy-to-operate VNAs offer wide dynamic range

摘要

Two new vector network analyzers incorporate a wide dynamic range, short measurement times, and a large touch screen. The ZNB is available in two-port and four-port models and covers the frequency range from 9 kHz to 4.5 GHz or 8.5 GHz. It provides a dynamic range of 140 dB, low trace noise of 0.004 dB (rms), and high output power of up to +13 dBm that adjusts electronically in a range of 90 dB. The ZNC, designed for testing passive RF components such as filters or cables, operates in a frequency range from 9 kHz to 3 GHz. It has two test ports and offers a sweep time of 11 ms with 401 points and a dynamic range of up to 130 dB.
