【R＆S ZVH4】は、基地局のアンテナやケーブルの敷設作業を行うエンジニア向けに開発されたアナライザ。ケーブル敷設後の損失測定や、ケーブル内部での破損状況を距離との関係から素早く見つけられるDTF(Distance-to-Fault)機能のほか、アンテナの評価に便利な反射測定機能など多彩な機能を標準搭載。測定結果はリニア、dB、VSWR、反射係数、mRhoでの表示が可能。

主な特長は以下。 (1)周波数範囲：100kHz～3.6GHz (2)アンテナの反射、DTFおよびケーブル損失評価 (3)フィルタやアンプの伝送特性評価が可能(オプション) (4)DC電源を持つ内蔵バイアスティを搭載 (5)ウィザード形式による簡単設定 (6)HTMLやpdfフォーマットによる自動レポート生成 (7)交換可能なリチウムイオン・バッテリで最高4.5時間動作

Features:

• Frequency range from 100 kHz to 3.6 GHz or 8 GHz
• 100 dB (typ.) dynamic range for filter and antenna isolation measurements
• Built-in DC voltage supply (bias) for active components such as amplifiers
• Saving of measurement results on SD memory card or USB memory stick
• Easy operation with user-configurable test sequences (wizard)
• Easy-to-replace Li-ion battery for up to 4.5 h of operation
• Rugged, splash-proof housing for rough work in the field
• Easy handling due to low weight (3 kg with battery) and easy-to-reach function keys
