Rohde and Schwarz ZNH4 - 30 kHz to 4 GHz Handheld Vector Network Analyzer (1321.1611.04)

30 kHz to 4 GHz frequency range
Catalog number: 1321.1611.04
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

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)

Several versions available

The ZNH is available in four models, with maximum frequencies ranging from 4 to 26.5 GHz. The following is a brief overview of the main features of each.

Model	Catalog	Maximum frequency	Number of ports	CAT functionality	S-parameter	RF Connector
ZNH4	1321.1611.04	4 GHz	2	Standard	Standard	N
ZNH8	1321.1611.08	8 GHz	2	Standard	Standard	N
ZNH18	1321.1611.18	18 GHz	2	Standard	Standard	N
ZNH26	1321.1611.26	26.5 GHz	2	Standard	Standard	PC 3.5mm

Four receiver architecture

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 test ports.

Simple to operate

The multi-touch screen 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 measurements with automated test sequences, speeding up the test process and reducing the potential for human error.

One-port cable and antenna measurements

With 16001 points per trace, the R&S ZNH can measure electrically long cables with no limitations. This enables the detection of cable discontinuities, which is important for base station antenna installation. For the one-port cable loss measurement, only one end of the cable needs to be connected to the R&S®ZNH test port; the other end can be terminated with a short circuit or left open.

Alternately, the antenna system performance can be assessed with reflection measurements. When a minimum amount of the transmitted signal is reflected, it indicates that the transmission energy efficiently covers the intended area. Unnecessarily high reflection makes the system inefficient and can damage components. Reflection measurements can be expressed in terms of return loss, VSWR, and the reflection coefficient.

Four S-parameter measurements

S-parameters are the basic measured quantities of a network analyzer. They describe how the DUT modifies a signal that is transmitted or reflected in the forward or reverse direction. During product development and manufacturing, it is common to test component specifications and verify design simulations to ensure systems and their components work properly. In the field, S-parameter measurement helps to verify and troubleshoot deployed RF and microwave systems. The full two-port R&S ZNH offers the four S-parameter (S11, S21, S12, S22) measurements as standard. The VNA features single, split, triple, and quad display modes and various formats.

Optional measurement modes

Power sensor support (ZHN-K9)

Any high-precision power measurement application, for instance, level calibration, requires very high accuracy to measure and align transmitting power. When equipped with the R&S NRPxx power sensors and the ZNH-K9 option, the R&S ZNH becomes an accurate RF power meter with a wide measurement range. Calibration is not required prior to making measurements since the sensors are fully characterized over frequency, level, and temperature and feature long-term stability. Zeroing is usually not required; the user can plug in a sensor and simply start measuring.

Pulse measurement (ZNH-K29)

The ZNH-K29 option enables precise pulse and peak power measurements using the ZNH together with a Rohde & Schwarz wideband power sensor. Field applications benefit from this compact, powerful combination.

During installation and maintenance of radar systems, pulse characteristics and output power have to be measured. Due to a maximum video bandwidth of 30 MHz and a rise/fall time of < 13 ns, the sensors can measure pulses with a pulse width as short as 50 ns.

When installing and maintaining even the latest generation of microwave link modules, the user benefits from the sensor's high measurement speed and wide dynamic range.

Automatic pulse analysis helps the user measure important pulse parameters. This analysis eliminates the need for complex measurements using markers. Changes in the pulse shape are immediately taken into account in the measurement results.

The following parameters are determined by automatic pulse analysis:

Time parameters: rise/fall time, start/stop time, pulse width, duty cycle, pulse period
Level parameters: pulse top, pulse base, peak, average, minimum, overshoot (positive and negative)

Pulse analysis with R&S ZNH-K29 and R&S NRP-Z81 wideband power sensors

DC bias variable voltage source (ZNH-K10)

Certain systems, such as tower-mounted amplifiers (TMA) for mobile communications applications, require DC power to be fed via the RF cable. Standard setups consist of a handheld analyzer, a 110V/230V plug-in power supply, a dedicated bias tee, and cables. The R&S ZNH has an integrated bias tee that does not require these components as additional external devices and can be battery-operated. The VNA acts as a hassle-free variable voltage source to provide the power these systems need for testing, installation, and maintenance.

Vector voltmeter (ZNH-K45)

The R&S ZNH-K45 vector voltmeter option displays the magnitude and phase of a DUT at a fixed frequency. The ZNH can therefore replace a conventional vector voltmeter for many applications. The required signal source and bridge are already available in the ZNH.

The setup is extremely simple, which makes the R&S ZNH-K45 ideal for field use. The results of relative measurements from a reference DUT can be stored at the push of a button. Comparison measurements, e.g. between various RF cables and a reference cable (golden device), can be quickly and easily performed. Typical applications are:

Adjustment of electrical cable length
Installation, maintenance, and troubleshooting of phase-controlled antennas, for instance, localizer antennas used in instrument landing systems (ILS) for air traffic control
Calibration of monopulse radars

Wave ratios and wave quantities (ZNH-K66)

R&S ZNH offers four fully coherent receivers/channels. This means there are two additional sets of measurement parameters, which have an unambiguous meaning even if the DUT is measured outside its linear range:

Wave quantities provide the power of any of the transmitted or received waves
Wave ratios provide the complex ratio of any combination of transmitted or received wave quantities

The wave quantities provide the absolute power and phase at the various receivers of the analyzer ports. Wave quantities are therefore suitable for the following measurement tasks:

Use of the analyzer as a frequency selective power meter
Harmonics

Wave ratio measurement

Wave quantities measurement
