The self alignment does not need to be repeated every time the instrument is switched on, because the instrument saves the values and loads them during booting automatically. A self alignment is recommended if the instrument is used at a temperature that differs considerable (more than 10°C) from the temperature present at the last self alignment.

The self test also does not need to be repeated every time the instrument is switched on. It is necessary only when instrument malfunction is suspected.

2.1.7 Switching Off the R&S ESPI

➢ Press the ON/STANDBY key on the front panel.

The R&S ESPI will store the current settings on the hard disk and then shut down the software. Once the operation has been completed, the power supply unit will be switched to STANDBY and the yellow LED will come on.

Shock hazard

In standby mode, the AC supply voltage is still present on the instrument.

➢ To completely disconnect the instrument from the AC power supply, change the power

switch on the rear panel to position O.

• The main power switch on the rear panel also interrupts the power supply of the OCXO (optional) inside the instrument. When you switch the instrument back on, be sure to adhere to the extended warm-up phase.

• If you switch off the instrument by using the power switch or by disconnecting the power supply connector, it is not possible to save the current instrument settings on the hard disk. In this case, the last settings that were stored on the hard disk will be loaded when you switch the instrument back on.

R&S ESPI Preparing for Use

Connecting External Devices

• Using the TTL interface allows you to attain significantly higher speeds than possible with a pure GPIB control, because the frequency switching mechanism of the R&S ESPI is directly coupled to the frequency switching mechanism of the generator.

• To increase measurement accuracy, use a shared reference frequency to operate the R&S ESPI and the generator. If no independent 10 MHz reference frequency is available, connect the reference output of the generator to the reference input of the R&S ESPI and use SETUP – REFERENCE EXT to configure the R&S ESPI to implement the external reference.

2.3.6.1 Connecting the R&S ESPI to the Generator

To couple the frequency setting and level setting of the generator to the R&S ESPI, set up the following connections:

1. Connect the GPIB interface of the generator to the IEC2 connector on the rear panel of the R&S ESPI.

2. (Optional:) Connect the TTL interface of the generator and the R&S ESPI.

➢ Alternative 1 (R&S SMR, R&S SMU):

Connect the AUX CONTROL connector of the R&S ESPI to the corresponding AUX connector on the rear panel of the generator (the connection cable is supplied together with the option R&S FSP-B10).

➢ Alternative 2 (R&S SME, R&S SMP, R&S SMIQ):

Connect the AUX CONTROL connector of the R&S ESPI to the TRIGGER, MARKER and BLANK connectors on the rear panel of the generator (the connection cable is also supplied together with the option R&S FSP-B10). Note the labelling on the TRIGGER, MARKER and BLANK lines.

➢ Alternative 3 (R&S SML, R&S SMG/SMGU, R&S SMH/SMHU, R&S SMX/SMY,

generators from other manufacturers): No TTL connection possible.

The generator type determines which one of the possible connections is suitable for the generator. For more information, refer to the Operating Manual for the generator.

3. Connect the reference frequency output of the generator to the reference frequency input (REF IN) of the R&S ESPI. or Connect the reference frequency inputs of the two instruments to an external frequency standard.

2.4.8 Installing Plug&Play Printers

Plug&play printers can be easily installed under Windows XP:

After you connect and switch on a printer, Windows XP automatically detects the printer and installs the associated driver, provided that the driver is contained in the Windows XP installation.

If Windows XP does not find the printer driver, it will prompt you to enter a path for the associated installation files. In addition to the pre-installed drivers, a number of additional printer drivers are found in the D:\I386 directory.

You can find a detailed step-by-step procedure in Appendix A, section “ Installing Non-

Plug&Play Printers” on page A.6.

When you install printer drivers that are not pre-installed on the instrument, the installation process will prompt you to specify the path containing the new driver. This can be a memory stick or USB CD-ROM drive (see the section “ Connecting USB Devices (e.g. a Power Meter)”

on page 2.12).

2.4.9 Installing Non-Plug&Play Printers

The procedure for installing non-plug&play printers is described in appendix A, section

“ Installing Non-Plug&Play Printers” on page A.6.

2.5 Configuring the LAN Interface (Option R&S FSP-B16 only)

The instrument can be connected to an Ethernet LAN (local area network) using the LAN interface connector on the rear panel. This makes it possible to transfer data over the network and to use network printers. In addition, the instrument can be remote-controlled via the network. The network card can be operated with a 10 MHz Ethernet IEEE 802.3 or a 100 MHz Ethernet IEEE 802.3u interface.

2.5.1 Connecting the Instrument to the Network

Before connecting the instrument to the network, consult your network administrator, particularly in the case of large LAN installations. Connection errors may affect the entire network.

Connect a conventional RJ-45 cable (not supplied) to the rear panel of the instrument and a network hub of the required LAN segment. Since the RJ-45 involves star configuration rather than bus cabling, no special measures need to be taken.

Setting up the connection does not cause any problems on the network. Likewise, disconnecting the instrument from the network does not cause any problems as long as no data traffic to and from the instrument is in progress.

2.5.2 Configuring the Network Card

2.5.2.1 Driver Installation

Under Windows XP, network card drivers do not need to be installed separately if the option R&S FSP-B16 has been factory-installed.

All you need to do is connect the network cable to the LAN-Interface connector on the instrument rear panel. Windows XP automatically detects the network connection and activates the required drivers.

Introduction

5.1 Introduction

This section describes a typical and simple measurement task for an EMI test receiver. Each operating step is explained with the aid of R&S ESPI for rapid familiarization of the user without the need to know all the details of the operating functions.

In the introductory example a standard measurement of level and frequency is performed with the aid of the SCAN TABLE. This measurement is an overview and pre-certification measurement to be performed before the final standard-conformal measurement is carried out. Each operating step is explained with the aid of R&S ESPI for rapid familiarization of the user without the need to know all the details of the operating functions.

If unknown (RFI) signals are to be measured, it is strongly recommended to provide for at least 10 dB RF attenuation at the RF input in order to protect the input circuit.

In the following example, the R&S ESPI is set to default values in the receiver mode. The default setup is activated by pressing first the RECEIVER hotkey and then the PRESET key.

The main default parameters in receiver mode are listed in the following table:

Parameter Setting

Receiver frequency 100 MHz

RF attenuation Auto

Preamplifier Off

Detector AV

Measurement time 100 ms

RES bandwidth 120 kHz

Demodulator Off

Trigger Free run

Measurement

Measurement and display of RFI signal levels versus frequency is one of the most frequent tasks performed by an EMI Test Receiver. In the case of unknown signals, PRESET values will mostly be used for the measurement. If levels higher than +137 dBµV (10 dB RF attenuation) are expected or possible, a power attenuator has to be connected in front of the EMI Test Receiver input. Very high levels may otherwise damage or destroy the attenuator or input mixer.

Main Test Receiver Functions

The main functions required for the level and frequency measurement are setting the SCAN TABLE (START FREQUENCY, STOP FREQUENCY, STEPSIZE), selecting the resolution

(IF) bandwidth (RES BW), setting the measurement time (MEAS TIME) and selecting the detectors (e.g. peak or average) and MARKER functions required for the analysis.

Measurement Sequence - Level and Frequency Measurement

In this example, the spectrum of the signal present at RF INPUT is recorded in the frequency range 150 kHz to 30 MHz. The SCAN TABLE and associated parameters are manually set. The example is generally suitable for all fast pre-compliance measurements required for measuring unknown noise spectra of DUTs in the development stage and for modifying prototypes and can be used as a basis for final tests later on.

The high speed of fully synthesized scans, the frequency and amplitude accuracy and the wide dynamic range of the R&S ESPI EMI Test Receiver are of utmost importance and very useful for these measurements.

4. Select the detectors.

Up to three detectors can be connected in parallel to simultaneously display the amplitude at every frequency as a function of detector weighting. When a parallel detector is selected, the slowest detector (in the sense of a calibrated measurement) determines the speed or the total measurement time required for the scan. The fastest scan is performed when the peak detector is used as the sole detector.

In the example, the peak detector (trace 1) and the average detector (trace 2; default) are used in an overview measurement.
