The 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 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 ZNH, a multifaceted handheld vector network analyzer, helps on-site field engineers remedy defective components detected in the system.
The basic version of the ZNH handheld VNA 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 ZNH enables field engineers to maintain and restore radar and satellite systems swiftly.

| Benefits |
|
Four Receiver Architecture
(Sophisticated RF architecture provides access to latest calibration types)
| The four receiver architecture consists of dedicated reference receivers and test receivers at both port 1 and port 2.
This allows the ZNH to support more advanced calibration types such as unknown through, open, short and match (UOSM) calibration.
This calibration is useful for DUTs with different input or output connector types at the tests ports.

Compact Powerhouse
(Outstanding RF performance in a small form factor)
| The portability and small footprint of the ZNH make it ideal for field measurements.
The ZNH also delivers high performance with the following features:
▪ Wide Frequency Range of 3- kHz to 4/8/18/26.5 GHz to support a side range of applications
▪ High dynamic range of up to 100 dB (typ.) to measure large level variations
▪ Highly accurate thanks to a low trace noise magnitude (RMS) of 0.0015 dB to 0.0040 dB (typ.) and a low trace noise phase (RMS) OF 0.02° to 0.04° (typ.)
▪ Built in receiver step attenuator at both ports which is adjustable in 5 dB steps from 0 dB to 15 dB
|
Simple to Operate
(Multi touchscreen, remote control and measurement wizard for a top user experience)
| The multi touchscreen offers the standard pinch to zoom function available on smartphones.
The ZNH supports typical phone control gestures, helping users feel at home.
Even if operators cannot access the instrument directly, free PC, Android and iOS remote control apps are available for seamless operation.
Furthermore, the measurement wizard helps simplify measurement with automated test sequences, speeding up the test process and reducing the potential for human error.
|
Simple Configuration
(Simple and fast setup with configuration overview menu)
| The ZNH has both keys and rotary knob as well as touchscreen controls.
The keys are large and well spaced out, allowing easy operation when wearing gloves.
The capacitive touchscreen offers a new kind of user experience:
▪ Directly interact with elements on the screen
▪ Access menus quickly
▪ Change frequency and span
▪ Add/move/delete markers
▪ and more
The configuration overview menu reduce the steps required to configure the measurement setting, enabling fast setup.
|
Simple to add Value
(Comprehensive standard features and simple option ordering)
| The ZNH base unit includes:
▪ Distance to fault measurements
▪ One port cable loss measurements
▪ Reflection measurement
▪ Transmission measurement
▪ Four S-parameters (S11, S12, S21, S22)
