      產品詳細介紹Product Introduction

      AT A GLANCE

      The R&S®ZNH is a full two-port handheld vector network analyzer (VNA) that offers one-port cable and antenna measurement and full two-port S-parameter measurements. The touch based interface simplifies operation and a configuration overview menu makes measurement preparation more efficient. The R&S®ZNH may have a small form factor, but it is complete in every detail and delivers high performance and all the key functionalities.

      Maintaining the operation of RF communications systems requires fast identification of any defects in the system components. The R&S®ZNH, a multifaceted handheld vector network analyzer, helps on-site field engineers remedy defective components detected in the system. The basic version of the R&S®ZNH can perform one-port cable and antenna measurements and four S-parameter measurements up to 26.5 GHz. With the addition of the power meter, pulse measurement, wave ratio and wave quantities functionalities, the R&S®ZNH enables field engineers to maintain and restore radar and satellite systems swiftly.

      The ordering concept for R&S®ZNH options is simple, straightforward and transparent, with no cross-option dependency.

      The spaced out keys, backlit keypad and ruggedized housing make the R&S®ZNH suitable for indoor and outdoor use as well as stationary and mobile environments. The VNA is ideal for tasks such as antenna system installation and maintenance, distance-to-fault measurements (DTF) on cables, one-port cable loss measurements and antenna matching measurements. The analyzer can also be used for development, production and service tasks where the measurement locations and test requirements constantly change.

      The R&S®ZNH offers flexible and straightforward operation. Depending on the application, it can be operated either via its 7" capacitive touchscreen (no display calibration required) or the keypad. The touchscreen enables users to adjust the most common settings, such as parameter settings, and manage markers with smartphone-like gestures.

      Tapping the configuration overview icon provides quick access to the menu for checking and changing the display options and parameters. This helps to reduce the number of steps required during setup and measurement.
