Basic Safety Instructions

1171.0000.42 - 09 Page 3

Operating states and operating positions

The product may be operated only under the operating conditions and in the positions specified by the
manufacturer, without the product's ventilation being obstructed. If the manufacturer's specifications are
not observed, this can result in electric shock, fire and/or serious personal injury or death. Applicable local
or national safety regulations and rules for the prevention of accidents must be observed in all work
performed.

1. Unless otherwise specified, the following requirements apply to Rohde & Schwarz products:
predefined operating position is always with the housing floor facing down, IP protection 2X, use only
indoors, max. operating altitude 2000 m above sea level, max. transport altitude 4500 m above sea
level. A tolerance of ±10 % shall apply to the nominal voltage and ±5 % to the nominal frequency,
overvoltage category 2, pollution degree 2.

2. Do not place the product on surfaces, vehicles, cabinets or tables that for reasons of weight or stability
are unsuitable for this purpose. Always follow the manufacturer's installation instructions when
installing the product and fastening it to objects or structures (e.g. walls and shelves). An installation
that is not carried out as described in the product documentation could result in personal injury or
even death.

3. Do not place the product on heat-generating devices such as radiators or fan heaters. The ambient
temperature must not exceed the maximum temperature specified in the product documentation or in
the data sheet. Product overheating can cause electric shock, fire and/or serious personal injury or
even death.

Electrical safety

If the information on electrical safety is not observed either at all or to the extent necessary, electric shock,
fire and/or serious personal injury or death may occur.

1. Prior to switching on the product, always ensure that the nominal voltage setting on the product
matches the nominal voltage of the mains-supply network. If a different voltage is to be set, the power
fuse of the product may have to be changed accordingly.

2. In the case of products of safety class I with movable power cord and connector, operation is
permitted only on sockets with a protective conductor contact and protective conductor.

3. Intentionally breaking the protective conductor either in the feed line or in the product itself is not
permitted. Doing so can result in the danger of an electric shock from the product. If extension cords
or connector strips are implemented, they must be checked on a regular basis to ensure that they are
safe to use.

4. If there is no power switch for disconnecting the product from the mains, or if the power switch is not
suitable for this purpose, use the plug of the connecting cable to disconnect the product from the
mains. In such cases, always ensure that the power plug is easily reachable and accessible at all
times. For example, if the power plug is the disconnecting device, the length of the connecting cable
must not exceed 3 m. Functional or electronic switches are not suitable for providing disconnection
from the AC supply network. If products without power switches are integrated into racks or systems,
the disconnecting device must be provided at the system level.

5. Never use the product if the power cable is damaged. Check the power cables on a regular basis to
ensure that they are in proper operating condition. By taking appropriate safety measures and
carefully laying the power cable, ensure that the cable cannot be damaged and that no one can be
hurt by, for example, tripping over the cable or suffering an electric shock.

Basic Safety Instructions

1171.0000.42 - 09 Page 4

6. The product may be operated only from TN/TT supply networks fuse-protected with max. 16 A (higher
fuse only after consulting with the Rohde & Schwarz group of companies).

7. Do not insert the plug into sockets that are dusty or dirty. Insert the plug firmly and all the way into the
socket provided for this purpose. Otherwise, sparks that result in fire and/or injuries may occur.

8. Do not overload any sockets, extension cords or connector strips; doing so can cause fire or electric
shocks.

9. For measurements in circuits with voltages V

rms

> 30 V, suitable measures (e.g. appropriate
measuring equipment, fuse protection, current limiting, electrical separation, insulation) should be
taken to avoid any hazards.

10. Ensure that the connections with information technology equipment, e.g. PCs or other industrial
computers, comply with the IEC 60950-1 / EN 60950-1 or IEC 61010-1 / EN 61010-1 standards that
apply in each case.

11. Unless expressly permitted, never remove the cover or any part of the housing while the product is in
operation. Doing so will expose circuits and components and can lead to injuries, fire or damage to the
product.

12. If a product is to be permanently installed, the connection between the protective conductor terminal
on site and the product's protective conductor must be made first before any other connection is
made. The product may be installed and connected only by a licensed electrician.

13. For permanently installed equipment without built-in fuses, circuit breakers or similar protective
devices, the supply circuit must be fuse-protected in such a way that anyone who has access to the
product, as well as the product itself, is adequately protected from injury or damage.

14. Use suitable overvoltage protection to ensure that no overvoltage (such as that caused by a bolt of
lightning) can reach the product. Otherwise, the person operating the product will be exposed to the
danger of an electric shock.

15. Any object that is not designed to be placed in the openings of the housing must not be used for this
purpose. Doing so can cause short circuits inside the product and/or electric shocks, fire or injuries.

16. Unless specified otherwise, products are not liquid-proof (see also section "Operating states and
operating positions", item 1). Therefore, the equipment must be protected against penetration by
liquids. If the necessary precautions are not taken, the user may suffer electric shock or the product
itself may be damaged, which can also lead to personal injury.

17. Never use the product under conditions in which condensation has formed or can form in or on the
product, e.g. if the product has been moved from a cold to a warm environment. Penetration by water
increases the risk of electric shock.

18. Prior to cleaning the product, disconnect it completely from the power supply (e.g. AC supply network
or battery). Use a soft, non-linting cloth to clean the product. Never use chemical cleaning agents such
as alcohol, acetone or diluents for cellulose lacquers.

Operation

1. Operating the products requires special training and intense concentration. Make sure that persons
who use the products are physically, mentally and emotionally fit enough to do so; otherwise, injuries
or material damage may occur. It is the responsibility of the employer/operator to select suitable
personnel for operating the products.

Basic Safety Instructions

1171.0000.42 - 09 Page 5

2. Before you move or transport the product, read and observe the section titled "Transport".

3. As with all industrially manufactured goods, the use of substances that induce an allergic reaction
(allergens) such as nickel cannot be generally excluded. If you develop an allergic reaction (such as a
skin rash, frequent sneezing, red eyes or respiratory difficulties) when using a Rohde & Schwarz
product, consult a physician immediately to determine the cause and to prevent health problems or
stress.

4. Before you start processing the product mechanically and/or thermally, or before you take it apart, be
sure to read and pay special attention to the section titled "Waste disposal/Environmental protection",
item 1.

5. Depending on the function, certain products such as RF radio equipment can produce an elevated
level of electromagnetic radiation. Considering that unborn babies require increased protection,
pregnant women must be protected by appropriate measures. Persons with pacemakers may also be
exposed to risks from electromagnetic radiation. The employer/operator must evaluate workplaces
where there is a special risk of exposure to radiation and, if necessary, take measures to avert the
potential danger.

6. Should a fire occur, the product may release hazardous substances (gases, fluids, etc.) that can
cause health problems. Therefore, suitable measures must be taken, e.g. protective masks and
protective clothing must be worn.

7. Laser products are given warning labels that are standardized according to their laser class. Lasers
can cause biological harm due to the properties of their radiation and due to their extremely
concentrated electromagnetic power. If a laser product (e.g. a CD/DVD drive) is integrated into a
Rohde & Schwarz product, absolutely no other settings or functions may be used as described in the
product documentation. The objective is to prevent personal injury (e.g. due to laser beams).

8. EMC classes (in line with EN 55011/CISPR 11, and analogously with EN 55022/CISPR 22,
EN 55032/CISPR 32)

R&S ENV4200 Safety Instructions

User Manual 1107.2470.12 - 03 E-5

1 Safety Instructions

These operating instructions are part of the device and must be available to the
operating personnel at all times. All safety instructions and remarks must be observed.

The R&S ENV4200 complies with Measurement Category CAT II according to
IEC 61010-2-30.

Electric shock in case of wrong connection order.

The protective earth (PE) connection for the V-network must not be removed until all
other connections have been disconnected.

Put the V-network into operation in the following order (connect additional PE first):

1. Connect V-network to additional protective earth.

2. Connect network to power supply network.
Take the V-network out of operation in the following order (disconnect additional PE

last):

1. Disconnect V-network from mains supply.

2. Disconnect V-network from additional protective earth.
All safety instructions and warnings given on the device and in this manual must be

strictly observed.
Incorrect operation of the V-network may expose users to a life-threatening electric

shock.
Users must receive suitable technical training.

Electric shock due to improper operation.

By design, V-networks exhibit high leakage currents. Moreover, by principle, such a
device does not have standard-compliant isolation and there is no fuse in the
measuring circuit (the R&S ENV4200 only has a fuse in the auxiliary circuit of the
ventilation system). Hence, users must be protected against touching conductive parts
that may carry live mains voltage.

To ensure this, the V-network must be put into operation only by qualified electrical
specialists. The applicable national regulations and standards must be observed as
part of the installation process.

R&S ENV4200 Safety Instructions

User Manual 1107.2470.12 - 03 E-6

Electric shock or fire hazard if the cross section of the connecting cables are too
small.

The operator, through consultation with an electrically skilled person, must ensure that
double-insulated connecting cables with a minimum cross section suitable for the
application are used.
The maximum power consumption of the device under test, the fuse rating of the
building installation and the cable length must be observed.
When installing the supplied cable sockets, the assembly instructions and the
requirements of the manufacturer must be observed

Since the permissible limit for the leakage current in line with EN 61010-1 as well as
the basic insulation for a device with degree of protection class I cannot be met due to
the required standard-compliant setup in line with CISPR 16-1-2 (EN 55016-1-2),
additional measures must be taken to protect the user against direct or indirect contact.

The operator is responsible for ensuring that protective measures in line with VDE
0100-410 (IEC 60364-4-41) are maintained while working with the V-network. Prior to
putting the V-network into operation, a secure connection must be made with the
protective conductor available on site. This connection must fully meet the
requirements for protective conductor connections. The connection must not be
opened until the V-network has been definitively disconnected from the mains supply.

It must be assumed that, when connecting with a flexible cable, the ground wire
connection can come loose. Before commissioning, the V-network must therefore be
connected with an additional protective conductor according to VDE 0100-540 Part 5­54 (IEC 60364-5-54) with a sufficient cross section between the protective earth
connection of the measurement room and the rear panel protective earth conductor
terminal

( ) of the R&S ENV4200.
Only then may the V-network be connected to the mains supply. Removal from service

must be performed in the reverse order: First disconnect the V-network from the mains
supply and only then disconnect the additional protective conductor connection.

If "electrical separation" is used as a protective measure, an electrical specialist must
decide at which points a ground connection or a connection to the protective earth
terminal available on site may be made.

In general, when the R&S ENV4200 is operated, make sure that the air supply is not
obstructed from above or below. Since the device has air vents located on the bottom
side, it must be placed upon a nonflammable base (e.g. metal plate) in order to prevent
a fire if the ventilation system fails.

R&S ENV4200 Introduction

User Manual 1107.2470.12 - 03 E-7

2 Introduction

There are two basic types of the artificial mains network (AMN), the V-network (V­AMN) which couple the unsymmetric voltages, and the delta-network (Δ-AMN), which
couple the symmetric and the unsymmetric voltages separately.

The R&S ENV4200 four-line V-network is used to measure disturbance voltages on
mains-dependent loads.

Its main functions are as follows:

● Supply the equipment under test (EUT) with AC supply voltage or DC supply
voltage

● Provide a standardized load impedance

● Deliver the unsymmetric disturbance voltage generated by the EUT to the test

receiver in a defined manner

● Decouple the test circuit from mains disturbances

The R&S ENV4200 V-network is built with air-core inductances (50 μH and 250 μH)
and conforms to the requirements specified in CISPR 16-1-2.

Additional equipment:

● Artificial hand

● 10 dB attenuator in decoupling branch

● Pulse voltage limiter at measurement output

● Remote control interface

● Separate power supply for control electronics and remote control interface

The V-network can be operated manually or under remote control via a TTL interface.

4 Preparing for Use

4.1 Unpacking the Device

Remove the device from its packaging and carefully check it for any damage. Should
there be any damage, inform the carrier immediately and keep the packaging to
support any subsequent claims. The original packaging is also useful for transporting
or shipping the device later on.

Both handles must be used when removing the V-network from its packaging and
when carrying it. Since it is very heavy (39 kg), it is recommended to always have two
persons carry the V-network. Otherwise, there is a risk of injury.

4.2 Setting Up the Device

Before putting the R&S ENV4200 into operation, make sure the following requirements
have been met:

● The V-network is connected to an additional protective earth conductor.

● The air vents are not blocked.

● No signal or operating voltages exceeding the permitted limits are present at the

inputs.

● The maximum permissible continuous current voltage at the outputs of the

instrument is not exceeded and that the outputs are connected correctly.

Observe the notes in the "Safety instructions" chapter and the protective earth
instructions in the "Protective earthing" section!

In general, when the R&S ENV4200 is operated, make sure that the air supply is not
obstructed from above or below. Since the device has air vents located on the bottom
side, it must be placed upon a nonflammable base (e.g. metal plate) in order to prevent
a fire if the ventilation system fails.

Ignoring these instructions may result in damage to the instrument.
R&S ENV4200 Preparing for Use

User Manual 1107.2470.12 - 03 E-14

4.3 Protective Earthing

Electric shock due to incorrect protective earthing.

Due to the design, V-networks do not have standard-compliant insulation, do not have
a fuse in the measuring circuit and exhibit high leakage currents. In order to protect the
user from contact with electrically live instrument parts, the protective earthing of this
V-network must be made by experienced electrically skilled personnel. The applicable
national regulations and standards must be observed as part of the installation
process.

Due to the V-network's operating principle, high leakage currents of up to 3 A are
applied to the housing. The housing of the V-network is applied to the AC supply
voltage at relatively low impedance. For this reason, the V-network must always be
connected to the protective earth prior to putting it into operation.

It must be assumed that, when connecting with a flexible cable, the ground wire
connection can come loose. Before commissioning, the V-network must therefore be
connected with an additional protective earth conductor according to VDE 0100-540
part 5-54 (IEC 60364-5-54) with a sufficient cross section of 6 mm2 between the
protective earth-connection of the measurement room and the rear panel protective
conductor terminal

( ) of the R&S ENV4200, so that even in the case of a faulty device under test, i.e.
in the event of a short circuit, the housing voltage is below 4 V.

Only then may the V-network be connected to the mains supply. Removal from service
must be performed in the reverse order: First disconnect the V-network from the mains
supply and only then disconnect the additional protective conductor connection.

Make sure that the RF reference ground is not impacted by disturbance voltages (e.g.
from an industrial network) when the protective earth terminal is connected to the
protective earth. If this is the case, the protective earth must be connected via a PE
choke. With the choke, make sure that no voltages constituting a shock hazard are
applied to the housing.

If "electrical separation" is used as a protective measure, an electrical specialist must
decide at which points a ground connection or a connection to the protective earth
terminal available on site may be made.

The protective earth connection must not be removed until all connections have been
disconnected from the mains supply. All safety instructions and warnings given on the
device and in this operating manual must be strictly observed.

R&S ENV4200 Preparing for Use

User Manual 1107.2470.12 - 03 E-15

4.4 AC Supply

Electric shock due to incorrect power supply.

Due to the design, V-networks do not have standards-compliant insulation, do not have
a fuse in the measuring circuit and exhibit high leakage currents. In order to protect the
user from contact with electrically live instrument parts, the power supply connection of
this V-network must be made by experienced electrically skilled personnel. The
applicable national regulations and standards must be observed as part of the
installation process.

The supply voltage is connected to the back side of the MC high current connections
(L1, L2, L3, N). Suitable MC cable sockets for establishing connecting cables are
included in the equipment supplied.

The MC cable socket with the identification color blue and label N (neutral conductor)
is intended for connection to the MC high current connection with the 'N' identifier, see

Fig. 4. The MC cable socket with the identification color black and the labels L1, L2

and L3 ('phase' or 'line') are intended for connection to the MC high current
connections with the L1, L2 and L3 labels.

Fig. 4 MC cable socket with the identification color blue and 'N' identifier (neutral conductor)

In line with the insulation requirements stipulated in the standard CISPR 16-1-2
(EN 55016-1-2), each phase of the V-network is connected to housing ground via 8 µF.
This is why the V-network may not be operated with a residual current device
connected ahead of it. Additional measures must be taken to protect the user against
direct or indirect contact.

R&S ENV4200 Preparing for Use

User Manual 1107.2470.12 - 03 E-16

V-networks such as the R&S ENV4200 may also not contain any power fuses.
Therefore, the connected mains supply must be sufficiently fused. The maximum
permissible continuous current voltage is 200 A. Accordingly, the power supply must
be protected at 200 A.

The device does not have an on/off switch. An interrupting device that the user can
easily reach must be provided at the AC supply end to prevent the user from working
with AC supply voltage. The AC supply voltage must not be activated until the V­network and the equipment under test are completely connected. Removal from
service must be performed in the reverse order: First disconnect the V-network from
the mains supply and only then disconnect the EUT from the V-network.

The V-network is not fused in the operating circuit. The user must ensure that the
operating circuit between the power supply and the V-network's power connector is
fused correctly.

R&S ENV4200 Preparing for Use

User Manual 1107.2470.12 - 03 E-17

4.5 Connecting the RF Reference Ground

The V-network is connected to the PE protective earth conductor of the power supply
through the protective earth conductor terminal. However, this is unsuitable as an RF
reference mass for interference voltage measurement. Therefore, the V-network must
be connected to an appropriate RF reference ground to obtain reproducible and correct
measurement results.

The RF reference mass used be connected over a wide metal sheet with eleven M6
screws (1) flatly to the side-installed ground bar (see Fig. 5).

Fig. 5 Connection to RF reference ground

R&S ENV4200 Preparing for Use

User Manual 1107.2470.12 - 03 E-18

Make sure that the RF reference ground is not impacted by disturbance voltages (e.g.
from an industrial network) when the protective earth conductor is connected to the
protective earth. If this is the case, the protective earth must be connected via a PE
choke. With the choke, make sure that no voltages constituting a shock hazard are
applied to the housing.

4.5.1 Avoiding Grounding Loops

To avoid grounding loops, the V-network should be grounded only once in the test
setup, if possible. An example of using a PE choke was already given above (ensuring
that the RF reference ground is not impacted by disturbance voltages from an
industrial network). Fig. 6 shows an arrangement with several artificial mains networks
(AMN), source: CISPR 16-2-1:2014 (Edition 3).

Fig. 6 Arrangement of PE chokes to avoid grounding loops

PE chokes for currents up to about 30 A are common. In case of higher currents, you
can make them yourself by using ferrite toroidal cores. The following rule applies: In
case of a short circuit, the voltage drop at the PE choke must not exceed 4 V.

4.6 Connecting the Auxiliary Voltage

Risk of fire in case of failure of the auxiliary voltage.

The R&S ENV4200 may not be operated without the auxiliary voltage since this
voltage is necessary for operation of the fan system. Failure of the fan system can lead
to an overheating of the V-network, and in extreme cases may cause a fire. The V­network can cause burns if touched.

Prior to connecting the auxiliary voltage, it is necessary to check whether the AC
supply voltage that is set on the V-network corresponds to the local AC supply voltage.
The R&S ENV4200 can be set for two different nominal AC supply voltages: 115 V and
230 V. In the 115 V setting, the nominal AC supply voltage range is 100 V to 120 V. In
the 230 V setting, the nominal AC supply voltage range is 220 V to 240 V.

Make sure to read and understand the safety instructions in this manual before setting
the device for a different AC supply voltage or replacing a fuse. The F1/F2 line fuses
are dimensioned to provide protection against overcurrent situations and short-circuits
in both voltage ranges. If the fuse is exchanged, the type IEC 60127-2/5 T2A H 250V
must be used (two spare fuses are part of the equipment supplied).

The AC supply voltage is changed as follows:

1. Remove the fuse holder in the low-temperature connector on the device's rear

panel
(it can be removed only when the power cable is not connected)

2. Remove the line voltage selector using a suitable lifting tool such as a

screwdriver, size 1

3. Set the AC supply voltage by correctly inserting (rotating) the line voltage selector

4. Close the flap on the power connector
The desired AC supply voltage should be visible in the display window.

User Manual 1107.2470.12 - 03 E-21

Fig. 8 Low-temperature socket, fuse holder and line voltage selector

After selection of the voltage range, connect the V-network to the supply voltage using
the supplied power cable. If the V-network is correctly connected, one of the four green
LEDs for displaying the test path should light up (depending on the position of the LINE
SELECTION rotary switch).

If the V-network is connected to 230 V and the voltage selector is set to 115 V, the V­network's internal F3/F4 fuses may blow. The internal F3/F4 fuses may be replaced
only by an authorized Rohde & Schwarz service center (two spare fuses are part of the
equipment supplied).

4.7 Connecting the Test Receiver

Connect the test receiver using a 50  coaxial cable to the test receiver output (50  N
female connector TO TEST RECEIVER).

The external conductor of the N female connector is connected to the grounding bars
of the V-network via the front panel.

4.8 10 dB Attenuator

The built-in 10 dB attenuator attenuates the disturbance voltage emitted by the EUT by
10 dB.

The attenuator ensures the 50 Ω termination required to meet the impedance

tolerance, improves matching with the test receiver and provides a sufficiently high
ohmic internal resistance to ensure correct functioning of the pulse limiter.

See voltage division factor in the test report.

4.9 140 dBµV Pulse Limiter

The switchable pulse limiter limits voltage peaks up to 140 dBµV at the RF output. This
corresponds to a measured disturbance signal level of 150 dBV. Please note that the
test receiver only covers a 9 kHz spectral component of a broadband disturbance
signal.

When the device is powered on, the pulse limiter is always activated and must be
intentionally switched off. This ensures that it cannot be accidentally switched off.

If the pulse limiter is switched on, the green LED lights up.
The voltage peaks are caused, for example, by

● High disturbance voltages originating from broadband interferers

● Switching on and off

● Pulses from the mains supply

User Manual 1107.2470.12 - 03 E-23

4.10 Connecting the EUT

The device under test is connected with the connecting cables to the front side of the
MC connector plug (L1, L2, L3, N). The maximum permissible continuous current
voltage is 200 A.

Suitable MC cable sockets for establishing connecting cables are included in the
equipment supplied.

The MC cable socket with the identification color blue and label N (neutral conductor)
is intended for connection to the MC high current connection with the 'N' identifier, see

Fig. 4. The MC cable socket with the identification color black and the labels L1, L2

and L3 ('phase' or 'line') are intended for connection to the MC high current
connections with the L1, L2 and L3 labels.

In order to mimic the influence of the user's hand while measuring the disturbance
voltage, usage of an "artificial hand" is required for EUTs that are normally held in the
hand. The artificial hand consists of a metal foil that must be connected to the RF
reference ground via an RC combination. The RC combination is a series connection
of a 220 pF capacitor C and a 510 Ω resistor R that is built into the R&S ENV4200. It
can be connected to the EUT via the 4 mm banana jack on the front (ARTIFICIAL
HAND).

R&S ENV4200 Operating the V-Network

User Manual 1107.2470.12 - 03 E-24

5 Operating the V-Network

The V-network is not fused in the three-phase circuit. The user must ensure that the
operating circuit between the power supply and the power connector of the V-network
is fused correctly (see also chapter AC Supply).

When the R&S ENV4200 is operated, make sure that the air supply from above and
below and from the side is not obstructed. The device may not be operated
unsupervised and must be placed on a nonflammable base (e.g. metal plate) in order
to prevent a fire if the ventilation system fails.

Whenever the V-network is put into operation, check the correct functioning of the fans
by pressing the fan button. This is required to prevent any damage due to overheating.

The ventilation of the V-network is automatically set to full fan speed at an internal
housing temperature of approx. 50 °C, and the fan LED is illuminated in orange when
the auxiliary voltage is connected to the mains. If the coil temperature is > 100 °C, an
acoustic alarm sounds and the fan LED turns red.

In case of a high constant current load, the temperature of the connection elements
and the connection lines must be checked from time to time.

If the audible fan alarm sounds and the fan LED turns red, immediately disconnect the
V-network from the test load. The surface of the device can seriously overheat,
causing a risk of burns. If this happens, the device must undergo servicing and be
repaired if necessary.

5.1 Measurement Example

Fig. 10 shows the test setup for measuring disturbance voltages on a hand drill. The

artificial hand must be connected for this type of EUT. Three metal foils are arranged
on the hand drill and connected to the artificial hand (ARTIFICIAL HAND).

R&S ENV4200 Remote Operation

User Manual 1107.2470.12 - 03 E-27

The independent R&S ENV4200 control menu is used for remote control with R&S EMI
test receiver types ESW, ESL, ESRP, ESR, ESU and ESW, as well as for EMC32
software. The EZ-21 connecting cables (3 m oder 10 m) are used for open-loop control
with the ESU test receiver. The EZ-29 connecting cables (3 m oder 10 m) are used for
the ESL, ESRP, ESR and ESW test receivers.

For remote control with R&S EMI test receivers ESHS10, ESHS20/30,
ESAI/ESBI/ESMI, ESCS, ESS, ESPI and ESCI as well as in the ES-K1 and ESXS-K1
EMI software, the operating menu for the ESH2-Z5 V-network also applies for control
of the R&S ENV4200.

For control of the R&S ENV4200 with the R&S ESxI EMI test receivers ESAI; ESBI;
ESMI, the EZ-22 connecting cable is used. For control with other test receivers, the
EZ-21 connecting cables (3 m or 10 m) are used.

The pulse limiter cannot be remote-controlled. For reasons of safety, the pulse limiter
is switched on during remote control. If impairment of the disturbance spectrum is
suspected due to pulse limiting, the pulse limiter can be switched off on the front panel
and the measurement repeated manually.

R&S ENV4200 Preventive Maintenance and Care

User Manual 1107.2470.12 - 03 E-28

7 Preventive Maintenance and Care

The device does not need any periodic maintenance. Maintenance is essentially
restricted to cleaning the exterior of the device. Remove dirt from the housing with a
damp cloth. Do not use aggressive cleaning agents. The device should be switched off
during cleaning.

The network terminals (MC connector plug, MC cable socket, device connection) are
subject to wear and tear by mechanical and electrical strain. Accordingly, the AC
supply contacts should be regularly checked for bent, corroded or broken pins or
sockets as well as any signs that a fire might have occurred. Damaged AC supply
contacts must be replaced!

R&S ENV4200 Calibration and Recommended Recalibration Interval

User Manual 1107.2470.12 - 03 E-29

8 Calibration and Recommended

Recalibration Interval

The R&S ENV4200 V-network was calibrated by the manufacturer after completion of
production and was sent to the Rohde & Schwarz warehouse together with a
calibration certificate. Since the V-network is neither electrically nor mechanically
strained in the period between calibration and delivery to the warehouse and since
aging of V-networks in the warehouse is negligible due to the lack of active
components, the interval up to the first recalibration is counted from the date of
delivery.

It is recommended to have the re-calibration carried out by the manufacturer or by a
calibration laboratory authorized by the manufacturer.

The recommended recalibration interval is 1 year.
