EM510 Characteristics

4065.7763.32-01.00 2.2

2.2 Operating Modes and Control

The Fixed Frequency Mode is the standard mode of the receiver. In this mode a fixed frequency channel is set at which the signal is received, filtered and demodulated.

The following parameters can be set:  Frequency

Setting range from 9 kHz to 32 MHzin 1 Hz steps

 Demodulation mode

The following demodulation modes can be selected: – FM – AM – PULSE (AM PULSE) – PM – USB – LSB – ISB – CW – I/Q

 Bandwidth

The IF bandwidths can be selected in 30 steps between 100 Hz and 10 MHz.

 Measurement time (automatic or settable between 0.5 ms to 900 s)  Detector modes "continues" or "periodic"  Squelch

The level squelch can be set in 1 dB steps in the rangefrom -30 to +130 dBµV.

 AFC (Automatic Frequency Control)

With AFC switched on, the receiver frequency is tuned within the IF bandwidth.

 Level detector

For level measurement the detector can be switched to AVG, PEAK, RMS or FAST.

 Frequency offset detector  Attenuator

The attenuator operates in manual (0 to 25 dB) or automatic mode.

 Gain control (GC)

Automatic (AGC) and manual (MGC) gain control is selectable. The MGC setting covers the input signal range from -30 to 130 dBµV.

 Video Panorama

Spectrum of the demodulated signal with analysis features (squared AM, FM)

 IF Panorama (Option)

Independent from IFBW, settable from 10 kHz to 9.6 MHz

 ITU Measurement (Option)

AM modulation index (AM+, AM-, AM) FM deviation (FM+, FM-, FM) PM deviation (0 to 4π) Bandwidth (0 to 9.6 MHz)

Characteristics EM510

2.3 4065.7763.32-01.00

In theMemory Scan mode, the receiver settings can be programmed for the monitoring of up to 10000 channels. These channels can be scanned with the "Memory Scan" command. A single channel can be called with the "Recall" command.

The squelch level serves as a criterion for dwelling at the same frequency or switching to the next channel. lf the level criterion is met, the receiver allows for the selectable dwell time to elapse and then switches to the next channel.

Parameters selectable for each channel:

 Memory location status  Frequency  Demodulation mode  Bandwidth  Attenuator  AFC settings  Squelch parameters  Antenna number

The "Continue" command can be used to switch to the next channel before the dwell time has elapsed. In theFrequency Scan mode "Start Frequency", "Stop Frequency", and "Frequency Step" are defined

for monitoring a specific frequency range. This frequency range can be scanned with the "Frequency Scan" command.

The squelch level serves as a criterion for dwelling at the same frequency or switching to the next frequency. lf the level criterion is met, the EM510allows for the selectable dwell time to elapse and then switches to the next frequency. The demodulator settings are fixed for the defined search range. The "Continue" command can be used in this case to switch to the next frequency before the dwell time has elapsed.

In Memory Scan or Frequency Scan mode a selectable number of different measurements (e.g. level offset, AM modulation index, FM deviation, bandwidth) are performed in parallel.

In thePanorama Scan mode the receiver is tuned from start to stop frequency in nearly 10 MHz steps, performing a high resolution FFT at each step. The resolution bandwidth covers a range from 125 Hz up to 100 kHz, resultingin an outstanding scan speed of up to 600000 Ch/s or 16 GHz/s.

In the"Fixed Frequency Mode" a comprehensive selftest of the receiver can be performed. The test can be carried out in full or in a shorter version with only "GO" or "NOGO" being issued.

2.3 Design

(see Fig. 2-1: Front View,Fig. 2-2: Rear View and Fig. 2-3: Modules)

The EM510 basically consists of the following modules:

 Compact case  AC/DCconverter and power supply  HF receiver module  Fans

The compact case corresponds to the 19” standard and can be fitted into any 19” rack. Two brackets are provided at the sides for rack mounting.

At the rear on the right the interface and RF connectors are located. Three LEDs located above the 10/100 Base-T Ethernet LAN connector indicate linkstatus and activity. On the left there are the mains input socket with integral fuse holder and the DC source connector for feeding in the mains and DC supply voltage. Fuse F3 is for the DC supply voltage. The four feet of the compact case protect the connectors when the case is set down.

At the front the POWER switch, POWER LED and HEADPHONE socket are located. The HF receiver module is located in the left-hand part of the chassis. It is arranged in such a way that

the RF connections between the receiver and rear connectors are as short as possible. The interface connectors aredirectly accessible through an opening in the rear panel. The HF receiver module is designed as a slide-in module with its own front panel indicators and connectors.

The AC/DCconverter and the power supply are located in the right-hand part of the compact case. The two fans incorporated in the partition panel ensure sufficient cooling of the power supply and the

HF receiver module. There is no temperature-dependent control for adjusting the fan speed. The fans expel the hot air to the sides. Both side panels are equipped with ventilation slots for drawing

and expelling cooling air. On installing the EM510, sufficient room should be left at the sides of the unit to ensure an unhindered flow ofhot air.

2.4 Detailed Description

(see Fig. 2-4: EM510 Detailed Block Diagram) This section deals with the functions of the major functional blocks.

2.4.1 Power Supply Modules

The EM510 operates either on AC or on DC.

- DC voltage: 12 to 32 VDC

- AC voltage: 100 to 240 VAC (115, 230 VAC nominal) with a frequency of 50 to 60 Hz If both voltage sources are connected, AC supply operation is favored. If the AC supply fails, switch-

over to battery operation is effected automatically.

The mains connector is provided with two mains fuses (F1,F2) and an EMC filter. The mains fuses protect the electronic circuits against overload and short circuits. The EMC filter prevents radiated interference from leaving the equipment and also prevents picked-up and conducted interference from entering the equipment.

The external AC voltage is fed from the mains connector to the AC/DC converter. This converts the AC voltage into a DC voltage of 24 V, which is fed to the power supply.

The 12 to 32-VDC voltage is fed directly from the DC input tothe power supply. If the POWER switch on the front panel is on, a switch-over circuit in the power supplyconnects one of

the DC voltages. The POWER LED indicates whether or not power is being supplied to the power supply.

The power supply contains five DC/DC converters which provide the HF receiver module and the fans with the required operating voltages. The following stabilized voltages are generated:

Forthe HF receiver module  +5.15 0.15 VDC / 5.5 A

Forthe fans  +8 VDC / 0.5 A

All outputs are protected against short circuit and overvoltage. Green LEDs on the power supply indicate the presence of the DC input and supply voltages.

EM510 Characteristics

4065.7763.32-01.00 2.8

2.4.2 HF Receiver Module

The HF receiver module is controlled via the LAN interface X11.

The necessary signal inputs and outputs of the HF receiver module are routed via RF cables to the connectors on the rear and front panel or are available through the opening in the rear panel.

The RF antenna signal is fed in at connectorX1 RF and then taken via RF cable to the RF input of the HF receiver module. In the digital receiver the received signals are passed through the filters in the preselection on to the A/D converter, and are subsequently digitally filtered and demodulated to produce the baseband, video and AF signals.These signals can be transmitted in digital form via the LAN interface. Together with further output signals for detailed signal analysis and monitoring they are also made available via the following connectors:

Rear panel:

 X6 VIDEO A: Analog video output A for AM and I components  X7 VIDEO B: Analog video output B for FM and Qcomponents  X12a AUDIO: Audio output analog and digital  X14 FPDP: Wideband digital interface. FPDP (Front Panel Data Port) is a platform-independent 32-

bit synchronous data flow path that allows data to be transferred at high speeds (up to 1 Gbit/s), e.g. AF or baseband signal (I and Q) in digital form.

Front panel:  X10 AF: Phone jack (stereo socket AF_L; AF_R), AF analog headphone output (600 line and

headphones)

For the purposes of synchronization the following inputs and outputs are available on the rear panel:

 X8 REF OUT: Output for internal reference signal, f = 10 MHz  X9 REF IN: Input for external reference signal, f = 10 MHz

The HF receiver modulecan use an internal frequency reference or can be set to synchronize to the external frequency at X9 REF IN to provide even better frequency accuracy and stability.

Characteristics EM510

2.9 4065.7763.32-01.00

2.4.3 Fans

The two 12-VDC fans for cooling the power supply and the HF receiver module are supplied with a reduced voltage of approximately 8 VDC to operate the fans below maximum speed. This increases the life of the fans and additionally reduces acoustic noise.

The rotation speed of thefans is constant and not controlled as a function of the temperature.

5 Remote Control via LAN with SCPI Command

Syntax

5.1 Introduction

The EM510 can be remote controlled via LAN by means of SCPI command syntax. The control commands and the status reporting system are described in this chapter. The socket RJ45 is on the back side of theEM510.

Within the TCP/IP protocols, the EM510 supports the SCPI command syntax version 1993.0 (Standard Commands for Programmable Devices). The SCPI standard is based on IEEE 488.2 and is aimed at standardizing device-specific commands, error handling and status registers (see "Notation" on page

5.13). This section assumes a basic knowledge of programming and controller operation. The requirements of the SCPI standard for command syntax, error handling and configuration of the

status registers are explained in the relevant sections. Tables and figures provide a fast overview of the commands implemented in the device and the bit assignment in the status registers. The tables are supplemented by a comprehensive description of every command and the status registers. Detailed programming examples of the main functions are to be found in Annex E: LAN Programming Examples.

5.1.1 Remote Control via LAN interface

The default values of the interface parameters of the EM510 are configured

with the host name or IP-address 89.10.11.23 and port number 5555.

For more information see the Interfaces Description in the annex.

1. Connect the unit with controller via Ethernet cable by RJ45 plugs. In case of a direct connection to a

computer network card a crossed cable must be used. If the EM510 is connected via hub or directly to a network, a 1-to-1 cable is required.

2. TCP/IP must be installed on the controller. The network card can be set to half duplex or full duplex.

The EM510 determines the respective configuration during the switch-on and reacts correspondingly.

3. If the EM510 is operated in a network, it must be set to a network-compatible IP address. Consult

your network administrator for further information. See also Annex D: LAN Configuration.

4. The ping command is a simple way to check whether the controller is able to connect to the EM510.

Just enter the command “ping <IP address>“ (e.g..: “ping 89.10.11.23“) “ in the DOS box.

5. Commands can be sent to and messages received from the EM510 by means of a Telnet

application which is started and configured with the interface parameters of the EM510.

6. To test the connection, enter *idn?, for example, to query the EM510's identification. The response

string should then be displayed.

Note: If the same IP address already exists for a different device, the corresponding entry must be erased from the ARP table before setting up a new connection. This can be done in the DOS box by entering the command "ARP -d <IP address>".

5.1.2 Setting the IP Address and Port Number

The configuration of the LAN interface is described in Annex D: LAN Configuration. IP address and port number settings will take effect immediately. The EM510 is capable of assumingan IP address dynamically assigned by RARP (see Annex D: LAN

Configuration).

5.2 Structure and Syntax of the Device Messages

5.2.1 SCPI Introduction

SCPI (Standard Commands for Programmable Devices) describes a standard command set for programming devices, irrespective of the type of device or manufacturer. The goal of the SCPI consortium is to standardize the device-specific commands to a large extent. For this purpose, a model was developed which defines the same functions inside a device or for different devices. Command systems were generated which are assigned to these functions. Thus it is possible to address the same functions with identical commands. The command systems are of a hierarchical structure. Figure 5-1 illustrates this tree structure using a section of command system SENSe, which operates the sensor functions of the devices. The other examples regarding syntax and structure of the commands are derived from this command system.

SCPI is based on standard IEEE 488.2, i.e. it uses the same syntactic basic elements as well as the common commands defined in this standard. Part of the syntax of the device responses is defined with greater restrictions than in standard IEEE 488.2 (see 5.2.4 "Responses to Queries").

5.2.2 Structure of a Command

The commands consist of a so-called header and, in most cases, one or more parameters. Header and parameters are separated by a "white space" (ASCII code 0 to 9, 11 to 32 decimal, e.g. blank). The headers may consist of several keywords. Queries are formed by directly appending a question mark to the header.

Note:

The commands used in the following examples are not in every case implemented in the device.

Common commands Common commands consist of a header preceded by an asterisk "*"

and one or several parameters, if any.

Examples: *RST RESET, resets the device

*ESE 253 EVENT STATUS ENABLE, sets the bits of

the event status enable register

*ESR? EVENT STATUS QUERY, queries the

contents of the event status register.

EM510 Remote Control via LAN

4065.7763.32-01.00 5.4

Device-specific commands

Hierarchy: Device-specific commands are of hierarchical structure (see Figure

5-1). The different levels are represented by combined headers. Headers of the highest level (root level) have only one keyword. This keyword denotes a complete command system.

Example: SENSe This keyword denotes the command system

SENSe.

For commands of lower levels, the complete path has to be specified, starting on the left with the highest level, the individual keywords being separated by a colon ":".

Example: SENSe:FREQuency:STARt 118 MHz

This command lies in the third level of the SENSe system. It sets the starting frequency of a scan to 118 MHz.

STARt

Figure 5-1: Tree structure of the SCPI command system using the SENSe system by way of an example

Remote Control via LAN EM510

5.5 4065.7763.32-01.00

Some keywords occur at several levels within one command system. Their effect depends on the structure of the command, that is to say, at which position in the header of a command they are inserted.

Example: OUTPut:OUTPut:SQUelch:STATe ON

This command contains the keyword STATe at the third command level. It defines the state of the SQUelch function.

OUTPut:FILTer:LPAS:STATe OFF

This command contains the keyword STATe at the fourth command level. It defines the state of the AF filter.

Optional keywords: Some command systems permit certain keywords to be optionally inserted

into the header or omitted. These keywords are marked by square brackets in the description. The full command length must be recognized by the device for reasons of compatibility with the SCPI standard. Some commands are considerably shortened by these optional keywords.

Example: [SENSe]:FREQuency[:CW]: STEP [:INCRement]

25 kHz

This command sets the stepwidth for frequency UP-DOWN to 25 kHz. The following command has the same effect:

FREQuency:STEP 25 kHz

Note:

An optional keyword must not be omitted if its effect is specified in detail by a numeric suffix.

Long and short form: The keywords can be of a long form or a short form. Either the short form

or the long form can be entered, other abbreviations are not permissible.

Example: Long form: STATus:QUEStionable:ENABle 1

Short form: STAT:QUES:ENAB 1

EM510 Remote Control via LAN

4065.7763.32-01.00 5.6

Note: The short form is marked by upper-case letters, the long form corresponds to the complete word. Upper-case and lower-case notation only serve the above purpose, the device itself does not make any difference between upper- and lower-case letters.

Parameter: The parameter must be separated from the header by a "white space". If

several parameters are specified in a command, they are separated by a comma ",". A few queries permit the parameters MINimum, MAXimum and DEFault to be entered. For a description of the types of parameter, refer to

5.2.5"Parameters".

Example: SENSe:FREQuency? MAXimum Response: 3000000000

This query requests the maximal value for the input frequency.

Numeric suffix: If a device features several functions or characteristics of the same kind,

the desired function can be selected by a suffix added to the command. Entries without suffix are interpreted like entries with the suffix 1.

Remote Control via LAN EM510

5.7 4065.7763.32-01.00

5.2.3 Structure of a Command Line

Several commands in a line are separated by a semicolon ";". If the next command belongs to a different command system, the semicolon is followed by a colon.

Example:

SENSe:FREQuency:STARt MINimum;:OUTPut:FILTer:LPAS:STATe ON

This command line contains two commands. The first command is part of the SENSe system and is used to specify the start frequency of a scan. The second command is part of the OUTPut system and sets the AF filter.

If the successive commands belong to the same system, having one or several levels in common, the command line can be abbreviated. To this end, the second command after the semicolon starts with the level that lies below the common levels (see alsoFigure 5-1). The colon following the semicolon must be omitted in this case.

Example:

SENSe:FREQuency:MODE CW;:SENSe:FREQuency:FIXed:AFC ON

This command line is represented in its full length and contains two commands separated from each other by the semicolon. Both commands are part of the SOURce command system, subsystem FREQuency, i.e. they have two common levels.

When abbreviating the command line, the second command begins with the level below SENSe:FREQuency. The colon after the semicolon is omitted.

The abbreviated form of the command line reads as follows:

SENSe:FREQuency:MODE CW;FIXed:AFC ON

However, a new command line always begins with the complete path.

Example: SENSe:FREQuency:MODE CW

SENSe:FREQuency:FIXed:AFC ON

EM510 Remote Control via LAN

4065.7763.32-01.00 5.8

5.2.4 Responses to Queries

A query is defined for each setting command unless explicitly specified otherwise. It is formed by adding a question mark to the associated setting command. According to SCPI, the responses to queries are partly subject to stricter rules than in standard IEEE 488.2.

1. The requested parameter is transmitted without header.

Example: SENSe:FREQuency:MODe Response: SWE

2. Maximum values, minimum values and all further quantities which are requested via a special text

parameter are returned as numerical values. Example: FREQuency? MAX Response: 3000000000

3. Numerical values are output without a unit. Physical quantities are referred to the basic units.

Example: FREQuency? Response: 100000000 for 100 MHz

4. Truth values <Boolean values> are returned as 0 (for OFF) and 1 (for ON).

Example: OUTPut:FILTer:STATe? Response: 1

5. Text (character data) is returned in a short form (see also 5.2.5"Parameters").

Example: SENSe:FREQuency:MODe? Response: SWE

Remote Control via LAN EM510

5.9 4065.7763.32-01.00

5.2.5 Parameters

Most commands require a parameter to be specified. The parameters must be separated from the header by a "white space". Permissible parameters are numerical values, Boolean parameters, text, character strings, block data and expressions. The type of parameter required for the respective command and the permissible range of values are specified in the command description (see

5.3"Description of Commands").

Numerical values Numerical values can be entered in any form, i.e. with sign, decimal point and

exponent. Values exceeding the resolution of the device are rounded up or down. The mantissa may comprise up to 41 characters, the exponent must lie inside the value range -999 to 999. The exponent is introduced by an "E" or "e". Entry of the exponent alone is not permissible. In the case of physical quantities, the unit can be entered. Permissible units are as follows:

for frequencies GHz, MHz or MAHz, kHz and Hz, default unit is Hz for times s, ms, s, ns; default unit is s

for levels dBuV; default unit is dBuV for percentage PCT, default unit PCT

If the unit is missing, the default unit is used.

Example:

SENSe:FREQuency 123 MHz = SENSe:FREQuency 123E6

Special numerical The texts MINimum, MAXimum, UP, DOWN and INFinity are interpreted as

special numerical values.

In the case of a query, the numerical value is provided.

Example: Setting command: SENSe:GCONtrol MAXimum

Query: SENSe:GCONtrol Response: 100

MIN/MAX MINimum and MAXimum denote the minimum and maximum value.

UP/DOWN UP, DOWN increases or reduces the numerical value by one step. The step

width can be specified for some parameter which can be set via UP, DOWN via an allocated step command (see page 5.1). Some parameters can only be changed in fixed steps ( e.g. SENSe:BWIDth UP).

EM510 Remote Control via LAN

4065.7763.32-01.00 5.10

INF INFinity represent + . In case of queries the numeric value 9.9E37 is

output. The INF value 9.9E37 is entered into the result buffers MTRACE and ITRACE for MSCAN, FSCAN or PSCAN to identify the range limit.

NINF Negative INFinity (NINF)represent -.. In case of queries the numeric

value -9.9E37 is output. This value is output when a measured value is queried and measurement is not possible because of the unit settings.

NAN Not A Number (NAN) represents the value 9.91E37. NAN is only sent as

device response. This value is not defined. Possible causes are the division of zero by zero, the subtraction of infinite from infinite and the representation of missing values (e.g. at TRACe[:DATA]?).

Boolean Parameters Boolean parameters represent two states. The ON state (logically true) is

represented by ON or a numerical value unequal to 0. The OFF state (logically untrue) is represented by OFF or the numerical value 0. 0 or 1 is provided in a query.

Example: Setting command:

OUTPut:FILTer:STATe ON

Query: OUTput:FILTER:STATe?

Response: 1

Text Text parameters (character data) observe the syntactic rules for keywords, i.e.

they can be entered using the short or long form. Like any parameter, they have to be separated from the header by a "white space". In the case of a query, the short form of the text is provided.

Example: Setting command: SENSe:FREQuency:MODE FIXed

Query: SENSe:FREQuency:MODE? ResponseFIX

Strings Strings must always be entered in quotation marks (' or ").

Example: SYSTem:SECurity: OPTion "123ABC" or

SYSTem:LANGuage 'English'

Remote Control via LAN EM510

5.11 4065.7763.32-01.00

Block data Block data (Definite Length Block) are a transmission format which is suitable

for the transmission of large amounts of data. A command using a block data parameter has the following structure:

Example: HEADer:HEADer #45168xxxxxxxx

ASCII character # introduces the data block. The next number indicates how many of the following digits describe the length of the data block. In the example the 4 following digits indicate the length to be 5168 bytes. The data bytes follow. During the transmission of these data bytes all End or other control signs are ignored until all bytes are transmitted. Data elements comprising more than one byte are transmitted with the byte being the first which was specified by SCPI command "FORMat:BORDer".

Expressions Expressions must always be in brackets. The device requires this data format

for the indication of channel lists. A channel list always starts with @ followed by a path name or channel numbers or ranges of channel numbers.

Example: ROUTe:CLOSe (@23)

5.2.6 Overview of Syntax Elements

The following survey offers an overview of the syntax elements.

;

The colon separates the key wordsof a command. In a command line the colon after the separating semicolon marks the uppermost command level.

The semicolon separates two commands of a command line. It does not alter the path.

The comma separates several parameters of a command.

The question mark forms a query.

The asteriskmarks a common command.

Quotation marks introduce a string and terminate it.

ASCII character # introduces block data.

A "white space" (ASCII-Code 0 to 9, 11 to 32 decimal, e g blank) separates header and parameter.

()

Brackets enclose an expression (channel lists).

5.3 Description of Commands

Note:

For an overview of commands see the tables in Annex K.

5.3.1 Notation

In the following sections, all commands implemented in the device are described in detail. The notation corresponds to a large extent to that of the SCPI standards. The SCPI conformity information can be taken from the list of commands in Annex K.

Indentations The different levels of the SCPI command hierarchy are represented in the

description by means of indentations to the right. The lower the level, the further the indentation to the right. Please observe that the complete notation of the command always includes the higher levels as well.

Example: SENSe:FREQuency:MODE is indicated in the description as follows:

SENSe first level . :FREQuency second level . . :MODE third level

Upper-/lower-case notation

Upper/lower-case letters serve to mark the long or short form of the keywords of a command in the description (see next section). The device itself does not distinguish between upper- and lower-case letters.

EM510 Remote Control via LAN

4065.7763.32-01.00 5.14

Special characters | A selection of keywords with an identical effect exists for some commands.

These keywords are given in the same line and are separated by a vertical stroke. Only one of these keywords has to be indicated in the header of the command. The effect of the command is independent of the keywords being indicated.

Example: SENSe

:FREQuency

:CW|:FIXed

The two following commands of identical meaning can be formed. They set the frequency of the device to 123 MHz:

SENSe:FREQuency:CW 123E6 = SENSe:FREQuency:FIXed 123E6

A vertical stroke in indicating the parameters marks alternative possibilities in the sense of "or". The effect of the command is different, depending on which parameter is entered.

Example: Selection of parameter for command

SENSe:GCONTrol:MODE FIXed MGC AUTO AGC

If the parameter FIXed is selected, the gain is determined by the MGC voltage. In case of AUTO the gain depends on the signal.

The two parameters MGC and AGC are synonymous forFIXed and AUTO.

[ ] Keywords in square brackets can be omitted in the header (see chapter

5.3.2"Common Commands"). The device has to accept the full command length due to reason of compatibility to SCPI standard.

Parameters in square brackets can also be optionally inserted into the command or can be omitted.

5.3.2 Common Commands

The common commands are taken from the IEEE 488.2 (IEC 625-2) standard. A particular command has the same effect on different devices. The headers of these commands consist of an asterisk "*" followed by three letters. Many common commands concern the "Status Reporting System" on page

5.128.

Command Parameter Unit Remarks

*CLS no query *ESE 0 to 255 *ESR? only query

*IDN?

only query

*IST? only query

*OPC

*OPT? only query *PRE 0 to 255 *RST no query *SRE 0 to 255 *STB? only query *TRG no query *TST? only query

*WAI

*CLS

CLEAR STATUS sets the status byte (STB), the standard event register (ESR) and the EVENt

sections of the QUEStionable and the OPERation register to zero. The command does not alter the mask and transition parts of the registers. It clears the output buffer.

*ESE 0 to 255

EVENT STATUS ENABLE sets the event status enable register to the value indicated. Query

*ESE? returns the contents of the event status enable register in decimal form.

*ESR?

STANDARD EVENT STATUS QUERY returns the contents of the event status register in decimal

form (0 to 255) and subsequently sets the register to zero.

*IDN?

IDENTIFICATION QUERY queries the unit about identification.

The output of the unit can be: "ROHDE&SCHWARZ,EM510,100.017/002, 01. 62-4065.8376.00"

100.017/002 = serial number of the unit

01.62 = firmware version number

4065.8376.00 = firmware identity number

*IST?

INDIVIDUAL STATUS QUERY states the contents of the IST flags in decimal form (0 | 1).

*OPC

OPERATION COMPLETE sets the bit in the event-status register to 0 if all previous commands

were carried out. This bit can be used for triggering a service request (see "Status Reporting System" on page 5.128).

*OPC?

OPERATION COMPLETE QUERY writes the message '1' into the output buffer as soon as all

previous commands were carried out (see "Status Reporting System" on page 5.128).

*OPT?

OPTION IDENTIFICATION QUERY queries about the options in the unit and outputs a list of

installed options. The options are separated by a comma.

Explanation for the output characters: SU = Spectrum Unit; IF Panorama (software option) PS = panorama scan (software option) IM = ITU Measurement Function (software option) SL = Selcall; Sel Call Analysis (software option)

Example for reply from the unit: SU,0,IM,SL

*PRE 0 to 255

PARALLEL POLL ENABLE sets the parallel poll enable register to the value indicated. Query

*PRE? returns the contents of the parallel poll enable register in decimal form.

*RST

RESET sets the device to a defined default status. The default setting is indicated in the description

of the commands.

*SRE 0 to 255

SERVICE REQUEST ENABLE sets the service request enable register to the value indicated. Bit 6

(MSS mask bit) remains 0. This command determines under which conditions a service request is triggered. Query *SRE? reads the contents of the service request enable register in decimal form. Bit 6 is always 0.

*STB?

READ STATUS BYTE QUERY reads out the contents of the status byte in decimal form.

*TRG

TRIGGER triggers the same actions as the INITiate:CONM[:IMMediate] command.

*TST?

SELFTEST QUERY triggers the module state test and yields a figure which is to be interpreted as

the bit field: Result = 0 -> all modules ok

Result 0 -> fault in one or several modules. The information about the possible error can be queried by means of the SYSTem:ERRor? command:

*WAI

WAIT-to-CONTINUE only permits the servicing of the subsequent commands after all preceding

commands have been executed and all signals have settled (also see "Status Reporting System" on page 5.128 and "*OPC").

. . :MODE LOWDistort| LOWNoise|NORMal

Selection of operating modes for different receiving conditions. In module "Preselection" there is a selectable amplifier behind the range filters. When "Low Distortion" is selected, the amplifier is cut off. This achieves the best linearity but the noise

figure will be correspondingly higher. This setting is especially recommended for areas with a lot of strong signals.

When "Normal" and "Low Noise" is selected, the amplifier is cut in. This achieves a good noise figure and at the same time good high-level signal characteristics because the receiving bandwidth is limited in front of the amplifier. This setting is recommended for normal receiving conditions.

At this setting with ATT OFF, excessively strong signals (approx. >97 dBµV) at the antenna entry may cause an overload of the A/D converter.

Notes:

As opposed to the EM550, the EM510 modes "Normal“ and "Low Noise“ are identical in meaning. However, both modes are permitted for reasons of compatibility.

Parameters:

LOWDistort low-distortion reception NORMal | LOWNoise normal reception, low-noise reception

. :MODE CONTinuous|PERiodic

Setting the continuous or periodic measuring mode. In thePERiodic measurement mode all detectors are discharged after the measuring time has elapsed,

and the next measurement is started. Only the individual measured values per measuring period are displayed. If the path to the result buffer MTRACE is enabled by command TRACE:FEED:CONTrol MTRACE, ALWays, a measured value is stored inMTRACE each time the measuring time has elapsed.

In theCONTinuous measuring mode the measuring detector is read out every 200 msec, irrespective of the measuring time. These current measured values are displayed. The measuring time has an effect on the level detectors. With AVG the measuring time determines the averaging time. With PEAK the measuring time determines the fall time. With FAST the measuring time does not have any impact since it is only the current value which is measured. If the path to the result buffer MTRACE is enabled by command TRACE:FEED:CONTrol MTRACE, ALWays, a current measured value can be stored in MTRACE.

The memory locations are addressed with the text (see "Parameters" on page 5.9) MEM0 to MEM9999 (memory location 0 to memory location 9999). Some commands allow the receiver (data set of receiver settings) to be addressed by Character Data RX, the currently set memory location by CURRENT and the next free memory location by NEXT .

The number of the currently active memory location can also be queried by the MSCAN:CHAnel? command.

MEMory . :CLEar <name> [,<count>|MAXimum]

Clearing the contents of a memory location. A certain number of memory locations to be cleared may also be specified.

Parameters

<name> MEM0 to MEM9999 | CURRENT <count> number of memory locations to be cleared from memory location

<name>; as a default value <count> = 1 is accepted

MAXimum clearing all memory locations from <name> to the last memory

<packed_struct> binary data set as <Definite Length Block> with the

following structure: Frequency in Hz 4 bytes = unsigned long integer Squelch threshold in 1/10 dBuV 2 bytes = signed integer Demodulation type 2 bytes = meaning:

0 = FM, 1 = AM, 2 = PULSe, 3 = PM, 4 = IQ, 5 = ISB, 6 = CW, 7 = USB, 8 = LSB

Bandwidth 2 Byte = enumeration:

0 = 100 Hz, 1 = 150 Hz, 2 = 300 Hz, 3 = 600 Hz, 4 = 1 kHz, 5 = 1.5kHz, 6 = 2.1 kHz, 7 =2.4 kHz, 8 = 2.7kHz, 9 = 3.1 kHz, 10 = 4 kHz, 11 = 4.8 kHz, 12 = 6 kHz, 13 = 9 kHz, 14 = 12 kHz, 15 = 15 kHz, 16 = 30 kHz, 17 = 50 kHz, 18 = 120 kHz, 19 = 150 kHz, 20 = 250 kHz,21 = 300 kHz, 22 = 500 kHz 23 = 800 kHz 24 = 1 MHz 25 = 1.25 MHz 26 = 1.5 MHz 27 = 2.0 MHz 28 = 5.0 MHz 29 = 10.0 MHz

Antenna number 1 byte = unsigned character 0 to 99 Attenuator 1 byte = unsigned character (0 to 25) Attenuator auto 1 byte = unsigned character (1 = on / 0 = off) Squelch function 1 byte = unsigned character (1 = on / 0 = off) AFC function 1 byte = unsigned character (1 = on / 0 = off) Set/Reset memory 1 byte = unsigned character (1 = set / 0 = reset)

-------------------------------------------------------------------------Total number of bytes = 16

Notes:



When loading the receiver data set (RX) the parameter <ACT> is ignored. It must however be specified.



When loading with <packed_struct> the byte order within the 2- and 4-byte elements is determined by the setting command FORMat:BORDer.

*RST state:

The contents of the memory locations are kept after *RST.

Example:

MEMory:CONTents MEM1,801 kHz,34, AM ,9 kHz,(@1),1,OFF,ON,OFF,ON

. :CONTents? <name>|RX

Query about contents of memory location.

Parameters:

<name> MEM0 to MEM9999 | RX | CURRENT

Result:

Depending on the setting by the command FORMat:MEMory either an ASCII data set or a binary data set is output:

The ASCII data set has the following structure:

<F>,<THR>,<DEM>,<BW>,<ANT>,<ATT>,<ATTA>,<SQUC>,<AFC>,<ACT> <F> frequency (see SENS:FREQ:CW?) <THR> squelch threshold (see OUTP:SQU:THR?) <DEM> demodulation type (see SENS:DEM?) <BW> bandwidth (see SENS:BWID?) <ANT> antenna number (see ROUT:CLOS:STAT?) <ATT> attenuator (see INP:ATT?) <ATTA> attenuator auto (see INP:ATT:AUTO?) <SQUC> squelch function (see OUTP:SQU:STAT?) <AFC> AFC function (see (SENS:FREQ:CW:AFC?) <ACT> set/reset for scan (1/0)

The binary data set is transferred as a <Definite Length Block> and has to be interpreted according to the above-mentioned format.

Notes:



During a query about the receiver data set (RX) the parameter <ACT> is not defined and has to be ignored.



When trying to read out an empty memory location the error message "MEMORY EMPTY" is generated.

EM510 SENSe Subsystem

4065.7763.32-01.00 5.58

5.3.15 SENSe Subsystem

Selection of demodulation bandwidth. Since in the EM510 the signal path is also used for the computation of the IF panorama, both the selection of the IF panorama and the selected demodulation bandwidth affect the selection of the preselection filter ranges.The broader frequency range determines the selection of the preselection filter range.

Parameters:

<numeric_value> value of bandwidth UP|DOWN to next|previous bandwidth MINimum|MAXimum sets the narrowest|widest bandwidth

*RST state:

9 kHz

Example:

4065.7763.32-01.00 5.60

. : DECoder:SELCall[:STATe] ON|OFF|1|0

Switching on and off the Sel Call Analysis.

The following selective call methods can be detected and decoded: CCIR7(2), CCIR1, CCITT, EEA, EIA, EURO, NATEL, VDEW, ZVEI1, ZVEI2, DTMF, CTCSS, DCS

The decoder automatically detects the most probable code and only this code is output. If several codes of equal probability are detected then all codes are output.

The codes are output exclusively via UDP (see Annex F: Datagram Communication).

Required receiver settings Selective call methods are generally frequency and phase modulated (FM/PM). Therefore the receiver

must be set for this type of demodulation. The bandwidth for the demodulation must conform to the signal that is generally between 15 and 30 kHz..

For the testing of the selective-calling functionality there is a web page within the device. This page can be called up via <IP address>/selcall.html.

Note:

Sel Call Analysis is only accessible with the installed software option EM510SL (Selcall).

Parameters:

ON|1 Decoder switched on OFF|0 Decoder switched off

*RST state:

Example:

SENSe Subsystem :DATA? EM510

5.61 4065.7763.32-01.00

. :DATA? [<data_handle>]

Query about the current measured values of active sensor functions. When only the command SENSe:DATA? is used to query measured values, the measured values reported back may be as old as 200ms. For display on the unit measured values are captured every 200 ms and put into a buffer.

In the event that current data are needed the command combination INIT;:SENSe:DATA? is to be used. As response to this query the current measured value is reported back.

When a complete measurement is to be started, possibly by using a predefined measuring time, for instance the command combination INIT;:SENSe:DATA? should be used. As a result, the measurement history is reset, i.e. the detectors are discharged, a measurement is started and the result is reported back when the measuring time has elapsed.

In order notto block remote-control communication during longer measuring times, the measured value should only be queried when the measurement has been completed. The measured value thus obtained is stored in MTRACe, provided that the path to the result buffer MTRACE was enabled with command TRACE:FEED:CONTrol MTRACE, ALWays. The unit may actively report the end of measurement (MEASUring bit in operation status register becomes inactive) via SRQ if the status register has been configured accordingly (see also "Status Reporting System" on page 5.128).

Note:

For this command the keyword SENSe must not be omitted as DATA? can be mixed up with the subsystem TRACe/DATA.

Parameters:

none output of the measured values of all active sensor functions; if no

function is switched on, an error -221, "Settings

Conflict" will be generated "[SENSe:]FREQuency:OFFSet" output of offset value or error "[SENSe:]VOLTage:AC" output of level value or error -221, "Settings Conflict"

Note:

With SW option EM510IM (ITU Measurement) installed, apart from level and offset the measurement functions AM modulation index , FM frequency deviation, PM phase deviation and bandwidth measurement are also available.

"AM" output of AM modulation index measurement value "AM:POSitive" output of AM positive modulation index measurement value "AM:NEGative" output of AM negative modulation index measurement value "FM" output of FM frequency deviation measurement value "FM:POSitive" output of FM positive frequency deviation measurement value "FM:NEGative" output of FM negative frequency deviation measurement value "PM" output of PM phase deviation measurement value "BANDwidth" output of band width measurement value
