3.1.1.6 Battery maintenance
Getting started
Preparing for use
The R&S ZNH comes with a lithium-ion battery. In general, these batteries are easy to
handle. When you handle the battery, follow the instruction mentioned in the safety
instructions and in the following chapters.
Handling
●
The battery has been designed for a specific application. Do not use it for any other
applications.
●
Do not connect batteries in series or parallel as it can cause serious damage.
●
Observe correct polarities during installation and charging.
●
Do not heat over 70°C. The battery contains thermal fuses that could activate and
render the battery inoperable.
●
The battery contains an electronic device for protection against deep discharge,
overcharge and short-circuiting between the terminals.
– If you cannot discharge the battery, it may be deep discharged. Charge the bat-
tery for 0.5 hours and check again.
– If you cannot charge the battery, it may be overcharged. Discharge the battery
and check again.
– If the battery has been short-circuited, charge it to reset the electronics.
– If the battery still does not work, contact the Rohde & Schwarz customer sup-
port.
●
Do not allow metallic objects to come into contact with the terminals.
●
Do not solder directly to the battery.
Storage
The battery self-discharges while not in use. When storing the battery for an extended
period of time, make sure to
●
Handle the battery carefully to avoid short circuits. Make sure that leads and terminals are insulated.
●
Keep the battery in the supplied packaging before use. The temperature should be
between -20°C to 50°C.
●
Store the battery at an initial state of charge between 15% and 50% of its capacity.
When calculating the initial state of charge, consider
– The maximum consumption of electronic devices
– The self-discharge of the battery - the higher the state of charge, the higher the
rate of self-discharge
●
Avoid a deep discharge of the battery. A deep discharge occurs when the state of
charge falls below 5% of the battery's capacity.
●
Recharge the battery at least every six months.
Should the battery voltage be low or even 0 V, the battery protection circuit may have

Measuring transmissions
The R&S ZNH now shows the (corrected) characteristics of the lowpass filter.
4.5.2 Reflection measurement
In a reflection measurement, the R&S ZNH transmits stimulus signal to the input port of
the device under test (DUT) and measures the reflected wave. Different trace formats
allow you to express and display the results. Only one analyzer test port is required for
the reflection measurements.
In principle, the reflection measurement involves the same steps as a transmission
measurement. Note on the following differences:
●
The basic test setup for reflection measurements involves a single DUT and analyzer port. You connect the input of your DUT to port 1 of the R&S ZNH.
●
Using the basic transmission test setup, you can measure and display reflection
and transmission measurements in parallel.
For more information, see Chapter 8.3.1, "S-Parameter measurements",
on page 163.
●
Choose the appropriate calibration configuration for reflection measurement.
A full two port calibration type ("TOSM" or "UOSM") corrects the system errors for
all transmission and reflection S-parameters.
●
Some of the trace formats are particularly suited for reflection measurements. For
instance, you can display the measured reflection coefficient, S11 in a smith chart to
obtain the complex input impedance at port 1.

4.6.2 Measuring power and return loss
With the directional power sensors R&S FSH-Z14 and R&S FSH-Z44, you can measure the power in both directions.
When you connect the directional power sensor between the source and the load, the
R&S ZNH measures the power from the source to load (forward power) and from the
load to source (reverse power).
The ratio between the forward and reverse power is a measure of the load matching.
The R&S ZNH displays it as the return loss or standing wave ratio.
The power sensors for the R&S ZNH have an asymmetrical design. Therefore, they
have to be inserted into the test setup in such a way that the "Forward" arrow on the
sensor points toward the load (in the direction of the power flux).
When measuring high powers, pay strict attention to the following instructions to avoid
personal injury and to prevent the power sensor from being destroyed.
Danger of skin burns and damage to the instrument
●
Never exceed the permissible continuous power.
●
See diagram on the rear of the sensor for the permissible continuous power.
●
Turn off the RF power to connect the sensor.
●
Screw the RF connectors tightly.
Test setup
Connect the power sensor cable to the USB port of R&S ZNH. If the power sensor is
having the binder connector (i.e R&S FSH-Z14, R&S FSH-Z44), the FSH-Z144 adaptor
cable is needed. Insert the directional power sensor between the source and the load.
The power sensors for the R&S ZNH have an asymmetrical design. Hence, you have
to insert them into the test setup in such a way that the "Forward" arrow (1➙2) on the

5.8 Managing datasets
The R&S ZNH provides functionality to manage (e.g. save, restore, delete) datasets
available in its internal memory or an external storage device.
Datasets
The R&S ZNH supports various types of datasets. The instructions below primarily
describe the management of datasets that you create on the R&S ZNH during measurements, for example measurement results and configurations. Note that these datasets have the file extension .set.
Datasets with the file extension .set are an image of measurement results and configurations. Thus, you can subsequently reproduce the context of the measurement.
Using the R&S InstrumentView software, you can use the datasets for documentation
purposes or post-processed it for a more detailed analysis later on. Note that datasets
also contain calibration data if calibration has been performed.
Templates
The R&S ZNH also supports various other types of datasets or templates. Such templates mainly contain additional requirements for a particular measurement, like limit
lines or channel tables.
Creating and editing of these templates are only possible with the functionality provided by the R&S InstrumentView software package. Note that the file extension
depends on the application of the template (for example, a template containing a channel table has the extension .chntab).

The folder structure shows all the available data storage devices. Possible storage
devices are the internal memory of the R&S ZNH, micro-SD card or USB flash drive.
The default storage device depends on which devices are connected to the R&S ZNH.
See "Storage device" on page 89.
The internal memory provides approximately 20 MB of data, therefore the number of
datasets you save on the R&S ZNH is limited. Each dataset needs about 100 kB of
memory, but this value can vary.
If you are using an external storage device, the number of datasets you can save is
limited only by the size of the storage device.
R&S ZNH shows the remaining memory on the storage device in the dialog box.
1. Select the storage device you want to save the data.
2. Select the folder you want to save the data.
3. Enter a filename in the corresponding input field.
The default filename for datasets is Dataset###.set with a new number in
ascending order for each new dataset. The file extension for datasets is .set.
If you enter another name, the R&S ZNH uses that name and assigns a new number to the filename if you save the data set the next time. This function allows you
to assign consecutive dataset filename without entering a new name every time
you want to save a dataset.
You can define the dataset filename at the "User Preference" dialog box. Select the
"Default Dataset Name" and enter the filename in the entry box.

6 Working with the measurement wizard
When testing antennas and making measurement which involves complex signals, it is
often necessary to perform a sequence of standardized and recurring measurements,
often in an environment that is not easily accessible. To make sure that measurements
are performed as required and to avoid a constant adjustment of parameters, the
R&S ZNH features a measurement wizard.
The measurement wizard allows you to combine several individual measurement configurations to a sequence of measurements (or measurement set). As all relevant
parameters have been set before the actual measurement and cannot be changed
once the measurement procedure has begun, the wizard is a good way to avoid mistakes and save time when setting up measurements. You can use the wizard for measurements in all the operating modes.
Note that it is necessary to install and use the R&S InstrumentView software package if
you want to configure the measurement steps and parameters in the measurement
wizard.
For details on the individual measurements you can perform with the wizard, refer to
the corresponding chapters.

●
Chapter 9, "Vector voltmeter", on page 189
●
Chapter 10, "Power meter", on page 192
●
Chapter 11, "Performing pulse power measurements", on page 202
You can use the wizard for measurements in all operating modes.
The following chapters illustrates the wizard measurements used in the "Cable &
Antenna" mode.
Note: It is necessary to install and use the R&S InstrumentView software package if
you want to access the measurement wizard.
6.1 Performing and configuring measurements
Before you can use the measurement wizard, you have to define a measurement set
using the "Wizard Set Editor" in the R&S InstrumentView software package.

Calibration data
The R&S ZNH adds the calibration data of each calibration you perform to a calibration
data folder available on its internal memory. Each dataset in the calibration data folder
is unique for a particular calibration method and a particular measurement configuration.
Note that the calibration is only valid for the instrument it has been performed on.
Before you start a measurement sequence with the measurement wizard, the
R&S ZNH compares the contents of the calibration data folder to the measurement
configurations and required calibration methods in the measurement sequence.
●
If the R&S ZNH has already been calibrated for a particular configuration, it
restores that data. Another calibration is not necessary.
●
If the R&S ZNH has not been calibrated for a particular configuration yet, calibration becomes necessary. The new calibration data is added to the calibration data
folder.
Therefore, calibration is necessary only for calibration methods that have not been
used for a particular measurement configuration before.
However, it is recommended to perform calibration regularly to keep measurements as
accurate as possible.
You can delete obsolete calibration data from the folder:
