data sheet.
Setting up the product
Always place the product on a stable, flat and level surface with the bottom of the
product facing down. If the product is designed for different positions, secure the
product so that it cannot fall over.
If the product has foldable feet, always fold the feet completely in or out to ensure
stability. The feet can collapse if they are not folded out completely or if the prod-
10Getting Started 1316.4697.02 ─ 07
R&S®ESRP
uct is moved without lifting it. The foldable feet are designed to carry the weight of
the product, but not an extra load.
If stacking is possible, keep in mind that a stack of products can fall over and
cause injury.
If you mount products in a rack, ensure that the rack has sufficient load capacity
and stability. Observe the specifications of the rack manufacturer. Always install
the products from the bottom shelf to the top shelf so that the rack stands
securely. Secure the product so that it cannot fall off the rack.

Safety and Regulatory Information
Safety Instructions
Handling batteries safely
The product contains exchangeable or built-in lithium polymer or lithium ion cells
or batteries. The use of the word battery in the following always means all types.
Only the battery contents are potentially hazardous. As long as a battery is
undamaged and the seals remain intact, there is no danger.
Impact, shock or heat can cause damage such as dents, punctures and other
deformations. A damaged battery poses a risk of personal injury. Handle a damaged or leaking battery with extreme care. Immediately ventilate the area since
the battery releases harmful gases. If you come into contact with the battery fluid,
immediately remove all contaminated clothing. Irritation can occur if the battery
fluid comes in contact with your skin or eyes. Immediately and thoroughly rinse
your skin or eyes with water and seek medical aid.
For safe handling, follow these rules:
●
Do not short-circuit the battery.
●
Do not mechanically damage the battery. Do not open or disassemble the battery.
●
Do not expose the battery to high temperatures such as open flames, hot surfaces and sunlight.
●
Only use the battery with the designated Rohde & Schwarz product.

●
Store the battery in the product or use the product packaging.
●
Dispose of exchangeable batteries separately from normal household waste
as specified by the local waste disposal agency.
If you disregard these rules, you risk serious personal injury or even death due to
explosion, fire or hazardous chemical substances. The product documentation
provides further details.
If exchangeable batteries or products with built-in batteries are defective, contact
the Rohde & Schwarz customer service. Rohde & Schwarz classifies the severity
of the defect. When returning batteries or Rohde & Schwarz products containing
batteries, use a carrier qualified to transport dangerous goods and notify the carrier of this classification. Follow the carrier’s transport stipulations in line with
IATA-DGR, IMDG-Code, ADR or RID.

4.1.3 USB Interface
The front panel provides two female USB connectors to connect devices like an
external keyboard or mouse. You can also connect a memory stick to save and
restore instrument settings and measurement data.
4.1.4 Noise Source Control
The noise source control female connector is used to provide the supply voltage
for an external noise source, for example to measure the noise figure and gain of
amplifiers and frequency converting DUTs.
Conventional noise sources require a voltage of +28 V in order to be switched on
and 0 V to be switched off. The output supports a maximum load of 100 mA.
4.1.5 RF Input 50Ω
The R&S ESRP provides an RF input for connection of a device under test (DUT)
to the R&S ESRP. The DUT is connected to the RF Input via cable and an approriate connector (for example a male N connector).

4.1.6 Probe Power
The R&S ESRP provides two connectors to supply accessories like transducers
or probes with power.
The probe power connector with five pins supports supply voltages of ±10 V and
ground. The maximum permissible current is 200 mA. This probe power connector is suitable, for example, for transducers from Rohde & Schwarz.
The probe power connector with three pins supports supply voltages from +15 V
to -12.6 V and ground. The maximum permissible current is 150 mA. This probe
power connector is suitable, for example, for high-impedance probes from Agilent.
4.1.7 AF Output
Headphones equipped with a miniature jack plug can be connected to the AF output female connector. The internal impedance is 10 Ω. The output voltage can be
set by using the volume control to the right of the female connector. If a plug is
connected, the internal loudspeaker is automatically switched off.
See also "Connecting headphones" on page 13.
4.1.8 Tracking Generator Output (Optional)
The R&S ESRP is equipped with an optional tracking generator and therefore
provides a tracking generator output connector.
The output of the tracking generator is connected to the DUT via a cable equipped with a male N connector. The female connector is available only with the
tracking generator option (R&S FSV-B9).

Sensitive DUTs concerning matching
For DUTs with sensitive RF characteristics with regard to matching (VSWR)
at the input, insert a 10 dB attenuator between the DUT and the tracking
generator.

4.2.1 AC Power Supply Connection and Main Power Switch
The AC power supply connector and main power switch are located in a unit on
the rear panel of the instrument.
The main power switch works as follows.
●
Position "I": The instrument is supplied with power and in operation.
The OCXO reference frequency is warmed up.
●
Position "O": The instrument is disconnected from the AC power supply.
For more information see Chapter 5.7, "Connecting the AC Power", on page 36.
4.2.2 LAN
The LAN interface can be used to connect the R&S ESRP to a local network for
remote control, printouts and data transfer. The assignment of the RJ-45 connector supports twisted-pair category 5 UTP/STP cables in a star configuration (UTP
stands for unshielded twisted pair, and STP for shielded twisted pair).
4.2.3 VGA Interface
The female VGA connector is used to connect an external monitor. Instructions
on how to connect an external monitor are provided in Chapter 5.12, "Connecting
an External Monitor", on page 41.
4.2.4 Ext Trigger / Gate In
The female connector for external trigger or gate input is used to control the measurement by means of an external signal. The voltage levels can range from 0.5
to 3.5 V. The default value is 1.4 V. The typical input impedance is 10 kΩ.
4.2.5 Ref In
As a reference signal, you can either use the internal reference, or connect an
external one. The setup menu is used to switch between the internal and an
external reference. The REF IN female connector is used as an input for a
1-20 MHz reference signal. The required input level is 0-10 dBm.

4.2.6 Ref Out
This connector can be used to provide an external reference signal (e.g. the
OCXO) to other devices that are connected to this instrument. The REF OUT
female connector can output a 10 MHz reference signal with an output level of
0 dBm.
4.2.7 GPIB Interface
The GPIB interface is in compliance with IEEE488 and SCPI. A computer for
remote control can be connected via this interface. To set up the connection, a
shielded cable is recommended.
For more information, refer to the user manual.
4.2.8 Trigger Output
The female BNC connector can be used to provide a signal to another device.
The signal is TTL compatible (0 V / 5 V).
You can control the trigger output with the functionality provided in the "In-/
Output" menu ([INPUT/OUTPUT] key).
The trigger output also controls signals by the frequency mask trigger available in
realtime mode (R&S ESR-K55).
4.2.9 IF / Video
The female BNC connector can be used for various outputs:
●
Intermediate frequency (IF) output of 32 MHz
●
Video output (1 V)
You can select between IF and video output with the functionality provided in the
"In-/Output" menu ([INPUT/OUTPUT] key).
