Features:

• 30 kHz to 26.5 GHz frequency range
• One-port cable and antenna measurement with basic instrument
• S-parameter (S11, S12, S21, S22) measurement with basic instrument
• 100 dB (typ.) dynamic range for filter and antenna isolation measurements
• Built-in receiver step attenuator to increase port input power range linearity
• Built-in DC voltage supply (bias) for active components such as amplifiers
• Easy handling due to low weight (6.8 pounds with battery) and spaced out function keys
• 7" color touchscreen display for intuitive operation with smartphone-like gestures

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 good 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 handheld VNA can perform one-port cable and antenna measurements and four S-parameter measurements. With the addition of an optional 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 ZNH basic unit includes:

• Distance to fault measurement
• One port cable loss measurement
• Reflection measurement
• Transmission measurement
• Four S-parameters (S11, S21, S12, S22)

There are also several optional measurement modes. More information on these can be seen further below. The part numbers are indicated in parentheses.

• Power sensor support (ZNH-K9)
• Pulse measurement (ZNH-K29)
• DC bias variable voltage source (ZNH-K10)
• Vector voltmeter (ZNH-K45)
• Wave ratios and wave quantities (ZNH-K66)
