Packing material
Retain the original packing material. If the instrument needs to be transported or ship­ped later, you can use the material to protect the control elements and connectors.
Risk of injury during transportation
The carrying handles at the front and side of the casing are designed to lift or carry the instrument. Do not apply excessive force to the handles. If a handle is ripped off, the falling instrument can cause injury.
As the R&S ZNA is very heavy (over 30 kg fully equipped), it must always be carried by two people using both carrying handles to avoid personal injury or damage to the instrument.

3.2 Positioning the Instrument

The network analyzer is designed for use under laboratory conditions, either on a bench top or in a rack. Notice the general ambient conditions at the operating site described under "Risk of instrument damage due to inappropriate operating conditions" on page 11.
Instrument damage caused by electrostatic discharge
Electrostatic discharge (ESD) can damage the electronic components of the instrument and the device under test (DUT). Electrostatic discharge is most likely to occur when you connect or disconnect a DUT or test fixture to the instrument's test ports. To pre­vent electrostatic discharge, use a wrist strap and cord and connect yourself to the ground, or use a conductive floor mat and heel strap combination.

3.3 Bench Top Operation

If the analyzer is operated on a bench top, the surface must be flat. The instrument can be used in horizontal or vertical position, standing on its feet, or with the support feet on the bottom expanded.

EMI Suppression
Risk of injury if feet are folded out
The feet can fold in if they are not folded out completely or if the instrument is shifted. Collapsing feet can cause injury or damage the instrument.
Fold the feet completely in or out to ensure stability of the instrument. Never shift the instrument when the feet are folded out.
When the feet are folded out, do not work under the instrument or place anything underneath.
The feet can break if they are overloaded. The overall load on the folded-out feet must not exceed 500 N.

3.4 Operation in a 19" Rack

The R&S ZNA can be mounted in 19" racks using the adapter R&S ZZA-KN6 (order number 1332.4498.02). Proceed according to the mounting instructions supplied with the rack adapter.
Risk of instrument damage due to insufficient airflow in a rack
If you mount several instruments in a rack, you need an efficient ventilation concept to ensure that the instruments do not overheat. Insufficient airflow for a longer period can disturb the operation and even cause damage.

3.5 EMI Suppression

Electromagnetic Interference (EMI) can affect the measurement results.
To suppress generated Electromagnetic Interference:
Use suitable shielded cables of high quality (see table below)

3.6 Connecting the Analyzer to the AC Supply

The network analyzer is automatically adapted to the AC supply voltage, which must be in the range of 100 V to 240 V at 50 Hz to 60 Hz. A line frequency of 400 Hz is also supported.
The mains connector is located in the upper part of the rear panel (see Chapter 4.2,
"Rear Panel", on page 26).
► Connect the network analyzer to the AC power source using the AC power cable
delivered with the instrument.
The maximum power consumption and the typical power consumption of the individual analyzer models are listed in the data sheet.

3.7 Starting the Analyzer and Shutting Down

The AC power switch is located in the upper part of the rear panel, above the mains connector; see Chapter 4.2, "Rear Panel", on page 26.
To start the analyzer, proceed as follows:
1. Switch the AC power switch to position I (On).
After power-on, the analyzer automatically goes to standby or ready state, depend­ing on the state of the standby toggle key at the front panel when the instrument was switched off last time.
14Getting Started 1178.6456.02 ─ 05
R&S® ZNA
Putting the Analyzer into Operation
Standby and Ready State
2. If necessary, press the standby toggle key on the front panel to switch the instru­ment to ready state.
The instrument automatically performs a system check, boots the Windows® oper­ating system and then starts the vector network analyzer (VNA) application. If it was terminated regularly, the VNA application restores all recall sets and instru­ment settings of the previous analyzer session.
To shut down the analyzer, proceed as follows:
1. Press the standby key.
Pressing the standby key causes the instrument to save all loaded recall sets, to close the VNA application, to shut down Windows®, and to go to standby state. Of course, you can also perform these steps manually, like in any Windows session.
2. If desired, set the AC power switch to position O (Off).
Risk of data loss
It is recommended to switch the analyzer to standby state before disconnecting it from the AC supply. If you set the power switch to 0 while the VNA application is still run­ning, you lose the current settings. Moreover, loss of program data cannot be excluded if the application is terminated improperly.
The AC power switch can be permanently on. It is recommendable, however, to switch it off if the instrument is not used for some time. When you switch the instrument back on, be sure to comply with the extended warm-up phase specified in the data sheet.
To guarantee the specified functionality, after turning off the R&S ZNA, you have to wait for at least 10 seconds before turning it on again. This rule applies to both the AC power off and the standby state.

3.8 Standby and Ready State

The standby toggle key is located in the bottom left corner of the front panel.
The standby power only supplies the power switch circuits and the optional high preci­sion quartz (R&S ZNA-B4, "Precision Oven Quartz Frequency Reference"). In this state, it is safe to switch the AC power off and disconnect the instrument from the power supply. In ready state, all modules are power-supplied. When switched to ready state, the analyzer initiates its startup procedure.
Observe the instructions for startup and shutdown in Chapter 3.7, "Starting the Ana-
lyzer and Shutting Down", on page 14.

Refer to the description of the "Display" softtool (System – [Display]) in the user manual or help system to learn how to customize the screen.
Most of the (virtual) keys in the upper part of the control window call up a related soft­tool of the analyzer GUI. Every softtool, in turn, provides access to a group of related settings and actions (see Chapter 5.2.3, "Softtools", on page 35).
The Trace keys give access to all trace settings, to the limit check settings, and to the marker functions including marker search.
[Meas]: select the measured and displayed quantity.
[Format]: define how measured data (traces) are presented.
[Scale]: define how traces are scaled.
[Trace Config]: store traces to memory and perform mathematical operations on traces.
[Line]: define limits for measurement results, visualize them in the diagrams and activate/deactivate the limit check.
[Marker]: position markers on a trace, configure their properties and select the for­mat of the numerical readout. Markers can also be used to locate specific points on the trace, define the sweep range, and scale the diagram.
The Channel keys give access to channel-related settings.
[Pwr Bw Avg]: define the power of the internal signal source, the IF bandwidth, and the sweep average.
[Sweep]: define the scope of measurement, including the sweep type and the num­ber of measured sweeps.
[Cal]: functions that are necessary to perform and manage calibrations.
[Channel Config]: functions for channel management.
[Mode]: set up channels for particular (non-standard) measurements.
[Offset Embed]: functions for embedding and deembedding a DUT.
The Stimulus keys define the sweep range, depending on the sweep type.

[Stop]
[Center]
[Span]
The System keys give access to (or provide) general system functions.
[File Print]
Create, save or load recall sets.
Save or load trace data.
Send the contents of the active diagrams to a file, to the clipboard, or to an
external printer (incl. content definition and printer setup).
[DUT]: starting point for DUT-centric measurement setup.
Define DUTs to be measured (type, properties)

Choose the measurements to be performed on a selected DUT.
The analyzer fimware then helps you to set up the channel(s) accordingly.
[Applic]: external software tools and optional extensions of the analyzer firmware.
[Display]: display settings and functions that activate, modify and arrange different diagrams.
[Setup]: general system settings that are not restricted to a particular recall set.
[Preset]: restores preset values.
The controls in the data entry panel are used to enter numbers, units, and characters. The appearance of the panel depends on the data type of the setting selected in the
Application Window.

left = numeric value right = string value
While most of the keys have their standard keyboard functionality, some keys and con­trols provide additional functionality:
The [abc] and [123] keys switch between the numeric and the string keyboard.
The wheel control at the right of the numerical data input panel increases and decreases numerical values, and scrolls within lists. [Step Size] opens an input box to select the steps (in units of the current physical parameter) between two consecutive numerical values. The step size is also valid for value changes using the up and down keys. See also Chapter 5.6.2, "Using the
Numeric Editor", on page 47.
