The R&S CMU incl. option R&S CMU-B17 in combination with signal generator R&S SMIQ incl. IQ fading simulator option R&S SMIQB14 can be used for receiver (RX) Bit Error Rate (BER) tests under fading conditions. The IQ output of R&S CMU-B17 transmitter (TX) path feeds the signal into R&S SMIQ’s IQ input. The R&S SMIQ forwards the faded RF signal directly to the receiver (RX) of the Device Under Test (DUT). The illustrated test set-ups are depending on selected mode of option R&S CMUB17. In Bypass w. I/Q IF OUT mode it is recommended to reduce to minimum the RF level of non faded traffic channel. For more information please refer to R&S application note 1MA07_0E „SMIQ as Fading Simulator for External Signals“.

The R&S CMU200 incl. option R&S CMU-B17 in combination with IQ fading simulator R&S ABFS or R&S SMIQ/SMIQB14 can be used for receiver tests under fading conditions. In this case the signal is forwarded to the device under test (DUT) via CMU RF interface.

Additional information for GSM:

To avoid influences on the fading profile it is highly recommended:

• To set all timeslots to the same level.

• To use for the TX signal of the R&S CMU the same RF frequencies and RF levels for both TCH and

BCCH.

• To switch hopping off. Based on external PC it is possible to perform an automated signal path calibration procedure. Both

instruments will be controlled via IEEE interface. An application note incl. software is available on R&S WWW.

R&S CMU200 as IQ generator / RF analyzer

Another important application is the generation of IQ signals meeting the relevant standards. The user can generate complex signals that may even originate from a real signalling sequence. Most mobile radio chipsets comprise a RF chip and a baseband chip that communicate with each other via an analog IQ interface. The R&S CMU-B17 IQ-interface can be used to access the two chips. In mobile radio development, different teams are often required for this purpose. The IQ interface allows development work to be divided in space and time.

R&S CMU200 as RF generator / IQ analyzer

If IQ signals are applied to the receive section of the tester, signal analysis can be performed in the same manner as when feeding a RF signal. In this connection, modulation analysis, for example, is useful since it evaluates the quality of an IQ signal. Modulation analysis yields analysis results such as IQ offset and IQ imbalance, which directly affect IQ signals, or even more complex evaluations such as error vector magnitude (EVM).

Remarks:

• The listed R&S CMU200 function groups support the option R&S CMU-B17 from SW version V3.10 on:

RF GSM (GPRS, EGPRS) IS136 CDMA2000 (IS95) WCDMA (3GPP FDD)

• Due to used modulation schemes Bluetooth and AMPS standards will not be supported.

• The upgrade of existing units can be performed at R&S Service Center Munich. Installation and

calibration costs must be considered in addition to the price of option R&S CMU-B17. Later on it will be possible to perform R&S CMU-B17 upgrades at local R&S Service Centers.

• The options R&S CMU-B17 and R&S CMU-B73 use the same mainboard connector of R&S CMU. Therefore either the R&S CMU-B17 or the R&S CMU-B73 can be ordered for a single instrument.

Aspects to be considered, if TX or RX signal paths are interrupted *:

The RF frequency of the R&S CMU influences the rotating direction of the IQ vector. The direction is inverted for RF < 1200.1 MHz, this can be compensated by changing I and Q

R&S CMU generator or analyzer RF frequency

100 kHz.. 1200.0999999 MHz 1200.1.. 2700.0 MHz

R&S CMU IQ output vector

R&S CMU IQ input vector

*) Please refer to Annex 1. The rotating direction must be considered, if the R&S CMU signal path

from Link Handler Board to Frontend and vice versa is interrupted; i.e. if the signal is not returned to the same R&S CMU block after external treatment. Examples:

• The rotating direction must not be taken into account, if the transmitted signal is routed from IQ output of R&S CMU-B17 to an external fading simulator and than returned to IQ input of CMU (pls. refer to chapter Applications, R&S CMU in combination with fading simulator R&S ABFS or R&S SMIQ/SMIQB14, R&S CMU provides the faded RF signal).

• The rotating direction must be considered, if the transmitted signal is forwarded to an external fading simulator and is not returned to IQ input of R&S CMU (pls. refer to chapter Applications, R&S CMU in combination with R&S SMIQ, R&S SMIQ provides the faded RF signal).

Inverted rotation. Swap I-output with Q-output for proper operation

Inverted rotation. Swap I-input with Q-input for proper operation

Normal rotation

Notes for measuring IQ / IF signals, applied to inputs of option R&S CMU-B17 on R&S CMU RX path:

• The RF spectrum analyzer function (RF Function Group) is not applicable.

• The displayed RF power levels are not directly related to applied IQ / IF voltages. The analyzer

settings of R&S CMU RF interface (RF1, RF2, RF 4 IN) have to be considered additionally (softkeys Analyzer Level / RF Max. Level).

• IQ inputs have a fixed attenuation of 2 dB; e.g. the RF power meter readout for an applied 500

mV IQ peak voltage will be 2 dB below the set RF Max. Level value.

• IF inputs do not have a fixed attenuation. The max. IF input level is 2 dBm. The RF power meter

readout for the mentioned max. IF signal level (2 dBm) will be 2 dB below the set RF Max. Level value.

• It is recommended to switch off the Autoranging Function.

• RF and IF trigger functions are not possible.

• WCDMA RF Compensation filter is switched off (I/Q IN/OUT, IF IN/OUT, IFIN_I/Q IN/OUT)

• WCDMA UE-Test: ACLR/SEM measurement is not applicable

Putting the Instrument into Operation CMU

Putting the Instrument into Operation

Caution!

Please make sure to follow the instructions of the following sections in order not to cause damage to the instrument or endanger people. This is of particular importance when using the instrument for the first time.

Unpacking the Instrument

! Take the instrument out of the shipping box and check whether the

items listed in the packing list (see separate yellow sheet after the title page of this manual) are all included.

remove protective cabs

Should the instrument be damaged, immediately notify the forwarder who shipped the instrument to you and keep the box and packing material.

! Remove the two protective caps from the front and rear of the CMU

and carefully check the instrument for damage.

For further transport or shipment of the CMU the original packing should be used, too. It is recommended to keep at least the two protective caps for front and rear side in order to prevent damage to the controls and connectors. The caps are also necessary if the CMU is transported in its transit case that can be ordered from Rohde & Schwarz.

Setting up the Instrument

Permissible operating positions of the CMU

• Horizontal position, standing on the feet.

• For applications in the laboratory or on a work bench, it is recommended that the support feet on

the bottom of the instrument be extended. For the LCD display, this provides the optimum viewing angle which typically ranges from perpendicular to the display front to approximately 30° below.

Notes: For safe and convenient operation of the instrument note the following:

Warning!

The feet must be fully folded in or out. Only in this way can the stability of CMU be guaranteed and reliable operation be ensured. With the feet out, the weight of other units put onto CMU must not exceed 30 kg. The units must be secured against slipping (e.g. by locking the feet of the unit at the top side of the enclosure).

When moving the unit with the feet out, the feet might collapse and fold in. To avoid injuries, the unit must therefore not be moved with the feet out.

! Do not cover the rear and lateral ventilation holes. ! Note the permissible ambient temperature according to the data sheet. ! Avoid moisture condensation. If it however occurs, the instrument must be wiped dry

before switching on.

! Note the warm-up time of the temperature-controlled OCXO reference oscillator (Option

CMU-B11/B12), see data sheet.

1100.4903.12 1.10 E-10

Page 57

CMU Putting the Instrument into Operation

Mounting in a Rack

Using the adapter ZZA-411 (order number 1096.3283.00) the instrument can be mounted in 19" racks according to the mounting instructions supplied with the rack adapter.

Note: For convenient operation of the instrument note the following:

! Allow for sufficient air supply in the rack. ! Make sure that there is sufficient space between the ventilation holes and the rack

casing.

Connecting the Instrument to the AC Supply

The CMU may be connected to one-phase AC supplies with nominal voltages ranging from 100 V to 240 V and nominal frequencies ranging from 50 Hz to 400 Hz (see inscription on the rear panel and data sheet). Depending on the options installed, the power consumption ranges from 120 W to 230 W.

Note: The CMU is automatically adapted to the AC supply voltage applied. External

Caution!

After moisture condensation, allow the instrument to dry before switching on. Note the permissible ambient temperature according to the data sheet. Do not cover the lateral and rear ventilation holes.

switchover or adaptation of the fuses are not necessary.

For the mains connection use the supplied mains connector.

Mains connector

As the instrument is designed according to the regulations for safety class EN61010, it must be connected to a power outlet with earthing contact.

Switching on the Instrument / Startup Test

The CMU can be switched on using the mains switch at the rear of the instrument and the ON/STANDBY key at the bottom left of the instrument front.

Mains switch

The mains switch can be set to two positions: 0 The 0 position implies an all-pole disconnection of the instrument

from the mains.

I In the I position, the instrument is in standby mode or in operation,

depending on the position of the ON/STANDBY key at the front of the instrument.

key

Start procedure

Startup menu

The ON/STANDBY key activates two different operating modes indicated by colored LEDs:

Standby Only the OCXO reference frequency oscillator (Option CMU-

B11/B12), if installed, is supplied with operating voltage. The orange LED (STANDBY) on the right is illuminated.

Operation In this operating mode, all modules of the instrument are

supplied with operating voltage. The green LED (ON) on the left is illuminated.

! To switch on the CMU set the mains switch to the position I. The CMU enters standby mode.

! Set the CMU to operating mode by pressing the ON/STANDBY key

once.

Caution! When switching on the CMU, no disk should be inserted in the

drive; otherwise, one of the actions stored on the flash disk will be performed.

After activation of the operating mode, the startup menu appears for a few seconds. While it is displayed the CMU performs a startup test.

Displays in startup menu

The display windows of the startup menu provide information on

• The startup procedure (Process)

• Instrument model, serial number and version of the CMU base software

(Info).

• Installed hardware and software options and equipment (Options). Available software options are listed with their version numbers.

• Progress of the startup procedure (Startup bar graph).

After terminating the startup procedure, the instrument changes to the last main menu or graphical measurement menu of the previous session.

Page 59

CMU Putting the Instrument into Operation

Switching off the Instrument

In order not to lose any settings that have been made, proceed in the following order to switch off the CMU:

! Remove any storage medium from the PCMCIA interface or floppy disk

drive.

! Shortly press ON/STANDBY to initiate the shutdown process and save

the current data to the internal hard disk.

! Wait until the shutdown process has been terminated before setting the

mains switch at the rear to the 0 position.

Note: Instruments equipped with a Front Module controller FMR 6

display the message Shutdown in Progress after the ON/STANDBY key has been pressed. Keeping ON/STANDBY pressed for about 4 s on those instruments initiates a hardware shutdown where data may be lost.

How to Ensure EMC

In order to avoid electromagnetic interference, the instrument may only be operated when it is closed and with all shielding covers fitted. Only appropriate shielded signal and control cables may be used.

Input Level

Caution!

− In order to prevent damage to the instrument note the maximum permissible input levels at the AF inputs AF IN and AUX 1 as well as for the RF inputs RF 1, RF 2 and RF 4 IN at the front of the instrument.

The CMU can be connected to the serial interface of a controller via one of the serial interfaces COM 1 or COM 2 and a so-called null-modem cable. The pin assignment and wiring of a null-modem cable are described in section Handshake of chapter 8. The technical specifications of the serial (RS-232-C) interface are also discussed in chapter 8 (refer to section Hardware Interfaces).

Either a 25-pin or a 9-pin connector can be used on the controller side. It may be necessary to use an appropriate adapter (see chapter 8, Hardware Interfaces).

! Proceed as described above to activate the Remote tab of the Setup

menu.

! In the Port table row, select COM 1 or COM 2 to activate one of the RS-

232 interfaces for data transfer.

After selection of a serial interface, the transmission parameters must be set to comply with the parameters of the addressed device. This is done in the Comm. (communications) tab of the Setup menu:

! To open the Setup – Comm. tab press the SETUP key at the front of the

instrument and activate the Comm. hotkey at the lower edge of the screen.

! In the table section corresponding to the selected COM port check the

settings for the Baudrate, Data Bits, Parity, and Protocol.

Software Update and Version Management CMU

Software Update and Version Management

Your CMU was delivered with the latest software and firmware version available. New firmware can be easily installed via the floppy disk drive (option CMU-U61) or the PCMCIA interface on the front of the instrument. In this case, the additional software options must be enabled by means of a key code entered in the Setup – Options menu (see chapter 4).

Installation of new firmware versions and the use of different applications and versions on the same instrument is made easier by the VersionManager described in the following section. Installation instructions are also given in chapter 1 of the operating manuals for the individual software options.

CMU VersionManager

The VersionManager is a tool designed to activate, delete, install, combine, or list different software versions in a convenient way. Moreover, it provides information on the hardware and software configuration of the instrument (Edit service tables, Scan disk), resets the startup settings stored in the

non volatile ram, copies information to an external storage medium (Write log files to disk, List all versions to disk), and loads and activates user correction tables (see section RF User Correction on p.

1.27 ff.).

The VersionManager is part of each CMU firmware version. It is opened automatically after the boot-up process if the CMU detects a storage medium in its floppy disk drive/PCMCIA slot that contains an installation version of the CMU firmware. Alternatively, it can be called up by pressing the Menu Select key after the boot-up sequence is terminated (from the moment when the CMU display turns black until the end of the 3-beep acoustic signal).

handles base software versions and network options separately. As a consequence, different versions of the base software can be combined with different options to create new firmware configurations. For example, it is possible to update the base software without affecting the associated network options or vice versa. Moreover, the same base software version can be installed several times and combined with different network options (and vice versa), so it may enter into several firmware configurations. The following simple rules apply:

• With a new version of a network option, it is only possible to update one

of the existing configurations. The following selection dialog is automatically skipped.

• With a new base software version, it is possible to either update an

existing configuration or create a new one. A dialog selecting between the two alternatives is opened:

CMU RF User Correction

RF User Correction

The purpose of the RF user correction is to compensate for an inevitable frequency and leveldependent attenuation in the test setup (frequency and level response correction). Level correction values are determined by means of a signal generator or power meter connected to the CMU’s input and output ports and stored to a file, which is transferred to the CMU in order to modify its RF generator level and to correct its RF analyzer results.

The correction values must be acquired independently for the input and output connectors of the instrument.

Output level correction

The correction values for output signals (connectors RF1, RF2 or RF3 OUT) modify the RF generator level so that the actual RF signal power at the input of the DUT is equal to the nominal RF generator level.

Once the correction tables have been transferred to the instrument, the RF user correction is an internal procedure. There are several advantages of using this internal correction method rather than post-processing the CMU results by means of an external measurement program:

• The input level correction affects all acquired RF power results

including derived quantities (e.g. the results of the limit check) without slowing down the speed of the measurements. Evaluating derived quantities by means of an external program can be tedious. The RF user correction ensures that all results, including the derived ones, are consistent.

• The user correction is included in all results displayed in the measurement menus.

• Correction data can be acquired individually for each instrument and stored to its internal hard disk.

If several testers are used in a production measurement system, the individual units are independent from each other and interchangeable.

Exception: The wideband power, which is provided in the Analyzer/Generator menu of the RF function group and in many network test applications, is always uncorrected.

1100.4903.12 1.29 E-10

Page 76

RF User Correction CMU

File Format for User Correction Tables

The user correction file is an ASCII file named USERCOR1.DAT that is stored in the directory C:\INTERNAL\USERCOR\ on the internal hard disk of the CMU. The file contains up to 6 independent tables to store the correction values for the 3 RF output connectors and the 3 RF input connectors of the instrument. Each table has the following structure:

[PortID]: [Freq1] [Freq2] ... [Freqn] [Level1]: [Dev11] [Dev12] ... [Dev1n] [Level2]: [Dev21] [Dev22] [Dev2n]

... ... ... ... ...

[Levelm]: [Devm1] [Devm2] ... [Devmn]

Comments in the file must be introduced by a double dagger #. Spaces and indentations are allowed for easier readability of the file. The first character in a line can be a minus sign but must not be a plus sign. The following example shows a valid user correction file:

# This is a comment # (any number of spaces is allowed) # indentations are allowed,

# spaces and TAB are used for separation

RF2in: 500 1000 1500 2000 10: 1.20 -1.2 -.23 -0.5 # comments are allowed at the end of a line 0: 0.34 1.14 1.20 -1.2

-10: 1.19 -1.19 -1.12 1.00

-14: -0.32 +1.11 -0.50 1.10

RF1in: 200 800 1500 10: +1.20 -.91 .5 0: -0.12 +1.11 -0.50

RF3OUT: 400 1000 1555 2500 10: 1.20 -1.20 -0.23 -0.5 0: 0.34 1.14 1.20 -1.2

-10: 1.19 -1.19 -1.12 1.00

-14: -0.12 +1.11 -0.50 1.10

Note: In general RF user correction tables are no longer valid after an update of the path

correction data, e.g. by means of the automatic calibration system R&S ACS. To ensure that outdated user correction data are not used inadvertently, the ACS renames all files c:\internal\usercor\ *.dat

➠

c:\internal\usercor\ *.bak after a change of the path correction

data. Existing *.bak files are overwritten.

Ranges of Values and Limitations

The table contains the following elements:

PortID

Frequency points

Identifier for the RF connector, written in upper or lower case letters and followed by a colon. The following port IDs are valid:

RF1IN, RF2IN, RF4IN for the 3 RF input connectors (input level correction) RF1OUT, RF2OUT, RF3OUT for the 3 RF output connectors (output level correction)

Frequency of the measured or generated signal in MHz, to be arranged in ascending order, starting in column 2 (lowest frequency). The frequency points must be integer numbers (i.e. integer multiples of 1 MHz) and can be distributed across the entire RF input and output frequency range of the instrument (see data sheet).

1100.4903.12 1.30 E-10

Page 77

CMU RF User Correction

Level points

Level of the measured or generated signal in dBm, to be arranged in descending order, starting in row 2 (highest level). The level points must be positive or negative integer numbers, followed by a colon, and can be distributed across the entire RF input and output power range of the connectors (see data sheet). Negative levels must be preceded by a minus sign “-“; using a plus sign “+” for positive numbers is not allowed.

Correction values

n times m level correction values for the measured or generated signal in dB (if n is the number of frequency points, which is equal to the number of correction values per table row, and m is the number of level points). The total number of correction values n times m must not exceed 120 (it is possible though to choose m=120 and n=1 and vice versa).

The level correction values must be in the range between -1.20 dB and +1.20 dB. This is sufficient to compensate for a frequency response or level response caused by the test setup. Larger, correction factors can be defined by combining the user correction with a constant external input or output attenuation (see section RF Connectors in Chapter 4). Two consecutive correction values may be separated by any number of spaces or tabs.

Positive (negative) correction values for an output signal compensate for an external attenuation (gain) and increase (decrease) the generator level. Positive (negative) correction values for an input signal are added to (subtracted from) the measured RF signal levels.

Interpolation Rules

The CMU uses the values in the correction tables to interpolate correction factors at arbitrary frequency and level values. The following rules apply:

• At constant frequency, the correction value associated to the level point P range between (P

+ Pm)/2 and (P

m+1

+ Pm)/2: The ranges with constant value adjoin each other

m–1

is valid in the level

in the middle between two consecutive level points.

• At constant level, the correction factors are linearly interpolated between consecutive frequency points.

CMU A Short Tutorial on CMU Operation

2 Getting Started

The following Chapter presents a sample session with the universal radio communication tester CMU. It is intended to provide a quick overview of the settings provided in the base system and the RF function group. No specific device under test is required. For an introduction to mobile network tests (e.g. tests of GSM900/1800/1900 mobile phones) please refer to the relevant operating manuals.

Before starting any measurement with the CMU, please note the instructions given in Chapter 1 for putting the instrument into operation. In Chapters 2 to 4 you will find detailed information on customizing the instrument and the display according to your personal preferences.

The steps to perform are explained on the left side of each double-page together with the results obtained on the CMU screen. On the right side, additional information is given. We also point out alternative settings and related measurements which could not be reported in detail.

For a systematic explanation of all menus, functions and parameters and background information refer to the reference part in Chapter 4.

A Short Tutorial on CMU Operation

The principles of manual operation – controls, operating menus, dialog elements and measurement control – are discussed in Chapter 3. Below we list some essentials for first users:

Condensed Operating Instructions

1. When using CMU for the first time it is useful to set it to the default state (RESET hardkey).

2. ENTER key: press even if "No" or "Yes" is displayed.

3. There is no Home menu but the MENU SELECT hardkey can be pressed in any state of the unit. A large popup menu is then displayed in which the function group (network etc.), signalling mode and measurement menus can be selected. Activate by pressing ENTER.

4. A front-panel LED indicates which of the RF connectors is configured as output. In the menu, the RF generator can be activated or deactivated with ON/OFF (green/red). The front-panel LED goes out if the generator is in the OFF position.

5. A front-panel LED indicates which of the RF connectors is configured as input. In the menu, the measurement can be controlled via the ON/OFF and CONT/HALT keys (ON (green), OFF (red) and HLT (yellow) states). In the OFF state, the LED goes out.

6. The SETUP hardkey allows to make static, measurement-independent default settings such as Remote or Time, to check which options are installed and to activate new software options.

7. The left softkey row is missing in the graphical menus. The softkeys on the right-hand side are used to change the hotkeys across the bottom and their functions. Pressing the Menus softkey (bottom right) allows a fast switchover between related menus using the hotkeys.

8. Signalling does not necessarily have to be activated by means of a general menu; for example, the Power menu for GSM mobile tests can be called up immediately, without transferring any signalling information. The user is popup-menu guided (as default) through the different CMU signalling states (messages: switch mobile on, registered, call setup). This menu guidance via popup menu can be switched off.

A Short Tutorial on CMU Operation CMU

How to access and close menus

A startup menu is displayed automatically when the CMU is switched on.

SETUP

Some general configuration and selection menus can be opened via the MENU SELECT, RESET, INFO, PRINT, HELP or SETUP keys on the front panel.

The hotkeys displayed across the bottom of a main menu or graphical measurement menu are used to switch over between different main menus or graphical measurement menus. Tabs in popup menus are also accessible via hotkeys.

In firmware versions <V3.05, the Group Config. softkey (always at the top left) is available in all measurement menus. This softkey opens a popup menu defining the input path and the trigger settings for the current function group and signalling state.

The Group Config. softkey is omitted in firmware V3.05 and later. Instead, the settings are available in the Connection Control menu, see below.

The Connect. Control softkey (always at the top right) is available in all measurement menus. This softkey opens a popup menu defining the input and output connectors, the external attenuation, the reference frequency as well as many network-specific settings.

In the Signalling test modes of many network options, the Connection Control menu is also used to set up and terminate a connection between the CMU and the DUT.

In firmware versions V3.05 and later, the Connection Control menu also contains the input path and the trigger settings for the current function group and signalling state.

If a special configuration menu exists for a measurement or for a generator the corresponding softkey is marked with a yellow arrow. The configuration menu is opened by pressing the softkey twice.

ESCAPE

1100.4903.12 2.2 E-9

... on Step 1

" Mains switch on the rear panel

When the mains switch at the rear is set to the O position, the complete instrument is disconnected from the power supply. When the mains power switch is set to the I position, the in- strument is in standby mode or in operation, depending on the position of the ON/STANDBY key on the front panel.

# ON/STANDBY key on the front panel

The ON/STANDBY key at the front of the instrument determines whether the instrument is in standby mode or in operation.

Standby mode:

Only the OCXO reference frequency oscillator (option CMUB11/B12), if installed, is supplied with operating voltage. The orange LED (STANDBY) is illuminated.

& Chapter 1

The CMU is automatically set to the AC supply voltage and frequency applied. Note the permissible ranges of AC voltages and frequencies indicated at the rear of the instrument and in the data sheet.

& Chapter 1

The behavior of the CMU when it is switched off depends on the Front Module controller type installed; see Chapter 1.

Operation:

The green LED (ON) is illuminated and all modules of the instrument are supplied with operating voltage.

... on Step 2

$ Startup menu

The startup menu displays the following information:

• The startup procedure (Process)

• Instrument model, serial number and version of the CMU

base software (Info).

• Installed hardware and software options and equipment (Options). Available software options are listed with their version numbers.

• Progress of the startup procedure (Startup bar graph).

% Wait hotkey

By default the CMU switches to the last main menu of the previous session after terminating the startup process. This is convenient if an interrupted session is to be resumed or if the instrument is generally used in a definite operating mode.

On the other hand, the Wait function can be used to access the configuration menus which can be opened by means of the front panel keys before the actual measurement is started.

While the Wait hotkey is active, a reset of the instrument is not possible.

& Chapter 4

The Default hotkey can be used to load the factory default settings for all function groups. Settings made and stored in the previous session are overwritten.

The CMU’s user interface has

been optimized with the aim of facilitating fast and easy switchover between the menus and measurement modes. This includes the general configurations which can be accessed from any measurement menu.

The most important selection and configuration menus such as Reset, Setup, Menu Select etc.are directly accessible via front panel keys.

" Menu Select menu

The Menu Select menu shows all function groups installed on your CMU. If a function group is selected the available test modes and measurement menus are indicated. Function groups representing digital network tests (such as GSM400/850/900/1800/1900-MS) are generally subdivided in the two test modes Non Signalling and Signalling, each containing a number of measurement menus.

The RF function group is available on any CMU regardless of the software options purchased. It comprises the three measurement menus Analyzer/Generator, Power and Spec- trum. All three measurement menus are directly accessible from the Menu Select menu.

... on Step 2

# Analyzer/Generator menu

The Analyzer/Generator menu contains several softkeys to

• Control the RF signals received and analyzed (Analyzer Level, Analyzer Settings)

• Control the RF signals generated (Generator)

& Chapter 4

For digital network tests refer to the relevant operating manuals. e.g.

GSM400/850/900/1800/1900-MS.

Chapter 4

The Generator softkey provides the most important settings of the

Generator tab of the Connection Control menu.

Defining a level and frequency via the Generator softkey and the associated hotkeys implies that a continuous signal (CW) with this level and frequency is generated.

The RF Max. Level defined via Analyzer Level, however, denotes the maximum input power which can be measured. This is identical with the upper edge of the Power diagram (see below). The permissible range of Max. Level depends on the input connector and external attenuation used (see section Analyzer Settings in Chapter 4).

Defining a (center) Analyzer Settings – Frequency implies that only signals around this frequency are analyzed.

The Analyzer Settings – RBW hotkey defines the resolution bandwidth of the analyzer.

$ The status of the Analyzer Power measurement is shown in

the corresponding softkey. For ongoing measurements, the result in the Power output field is constantly updated.

At present no input signal is available so that the Power output field shows an invalid result “– – –“

Once the softkey is selected, the Analyzer Power measure- ment can be switched off and on by means of the ON/OFF key. In contrast, the CONT/HALT toggle key halts the measurement after the next valid result has been obtained.

The Analyzer Level and Analyzer Settings softkeys correspond to the Analyzer tab of the Connec- tion Control menu.

Ch. 4 and Ch. 5

The options for the measurement status are ON, OFF, or HLT. The HLT state is reached after the end of a single shot measurement (see the section about measurement control in Chapter 5).

" RF connectors

The RF Connection Control menu configures the input and output connectors in the RF function group. The four connectors on the front panel differ by their permissible range of input and output powers (see Chapter 4 and data sheet). The values quoted on the left side are compatible with the rated specifications.

# External attenuation

An external attenuation can be reported to the CMU in order to compensate for known losses between the signal source and the device under test or the analyzer.

In our example, the (positive) difference between the analyzer power measured and the generator power can be reported as an external output attenuation at RF 2. The RF generator increases its level to maintain the commanded power of –27 dBm at the analyzer. The nominal generator power set in the RF level field is thus measured and indicated next to the Analyzer Power softkey.

Chapter 4

Settings made in the Connect. Control menus apply to the entire

function group RF Non Signalling.

Chapter 4

Note that an external attenuation reported to the CMU shifts the nominal permissible ranges of input and output levels.

Note: RF User Correction

In addition to the static external attenuation set-

tings, the CMU provides a systematic correction of the generated and measured RF power by means of user-defined, frequency and level-dependent correction tables; see section RF User Correction in Chapter 1.

" Trigger mode

The trigger mode is set in the Analyzer tab of the Connection Control menu or via the Trigger softkey in the graphical

measurement menus. With the default setting Free Run the measurement is not synchronized to the frequency of the incoming pulses: The trace is permanently shifted in horizontal direction.

To show a signal consisting of rectangular pulses (bursts) it is recommended to trigger by either the rising or falling edge of the IF power.

The Frequency softkey defines the frequency of the measured signal and the resolution bandwidth. The Input Level softkey configures the input level, the power range and an attenuation factor. The Time softkey configures the time axis.

Chapter 4

In addition to markers, a D-line can be used to measure a particular level in the diagram.

$ Resolution bandwidth

A spectrum analyzer can differentiate two spectral lines separated by a minimum distance corresponding to the bandwidth of the resolution filter.

The smaller the bandwidth the better the resolution and the larger the signal-to-noise ratio. If the resolution bandwidth is too large only the envelope of the spectrum can be measured.

In the Power measurement, the signal-to-noise ratio im- proves but the time resolution deteriorates when the resolution bandwidth is reduced.

% Scaling of the spectral diagram

The tools provided in the Spectrum menu are particularly suitable for scaling a spectral diagram with a sharp main lobe and symmetric, lower side lobes:

• The R to Pk hotkey (Marker softkey) places the reference

marker to the maximum (i.e. the main lobe) of the diagram.

• The Cnt to R hotkey (Marker softkey) centers the diagram

to the frequency of the main marker.

• Equivalently, the Center hotkey (Frequency/RBW softkey)

can be used to center the diagram.

3 Manual Operation

This chapter provides a survey of the CMU's operating concept. This includes a description of the basic menu types, the selection and setting of parameters, and a general discussion of measurement control. The operating menus in the CMU basic system, the RF function group, and optional function groups are presented in an overview at the end of this chapter and described in greater detail in Chapter 4.

Operating concept

Basic elements

Flexibility and uniformity

The CMU was designed for easy, intuitive operation. All menus rely upon a limited number of controls with analogous or identical function. Basic settings are discussed in section Measurement Control on page 3.16 and in Chapter 5.

The CMU is operated via softkeys and tables. Softkeys provide a fast access to the instrument functions. Tables facilitate the management of larger amounts of data.

The CMU permits to switch over between various operating modes (multi-mode operation). For this purpose, it is possible to change between the menus in almost any instrument state. The different function groups (RF, GSMxxx-MS etc., see also separate operating manuals for network test applications) can be operated in the same way; measurements of the same type belonging to different applications are standardized.

Controls

The CMU is operated under menu control via keys, softkeys and hotkeys:

9 softkeys with alternating function, ON/Standby key (p. 4)

Controls CMU

Rotary Knob

The rotary knob (spinwheel) can be used in two different ways:

• It is turned to select entries in list fields and tables and to vary (increment/decrement) numerical and alphanumerical entries.

• It is pressed to expand or compress table sections (thus replacing the ON/OFF key), to expand pull-down lists, to open auxiliary input fields, and to confirm numerical entries or selections (thus replacing the ENTER key).

Front Panel Keys

The keys located in the right-hand part of the front panel are combined to form groups according to their functions. They control

• Data input and variation

• Pre-selection of the menus

• Settings of the instrument, editor, help file and output

The keys are described with their function in Chapter 1, section Front and Rear View.

Softkeys

Softkeys are assigned to the nine keys located both at the left and at the right edge of the screen. To simplify the display, only the softkeys which are actually assigned in a menu are indicated (see menu example in Fig. 3-1).

Selection of softkeys:

⇓

The CMU provides selectable and non-selectable softkeys. A softkey is selected by pressing the associated key.

A selected softkey is highlighted by a blue frame. Softkey selection establishes a connection to settings and functions related to the softkey. These related functions can be initiated via keys (e.g. ON/OFF, CONT/HALT), or via the selected softkey itself (e.g. calling up popup menus by pressing a selected softkey again).

After the function has been terminated, or after another softkey is selected, the softkey returns to its initial state.

Softkey types and their function:

Softkeys perform definite tasks within the corresponding menus. Different types of softkeys are provided:

− Pressing the softkey (i.e. the associated key) causes an immediate response on the screen. Examples are the non-selectable softkeys Group Config. and Connect. Control used to call up popup menus.

− Pressing the softkey activates a dialog box, e.g. an input field.

1100.4903.12 3.2 E-9

Page 99

CMU Controls

− The softkey is a measurement control softkey (main softkey) indicating the

measurement state (RUN, OFF, HLT). A yellow triangle indicates that a popup menu providing configurations can be opened with the softkey (press once for selection, a second time for opening the popup).

A measurement can be started and aborted with the ON/OFF key (i.e. the ON/OFF key switches between the measurement states RUN and OFF). It can be stopped while preserving the valid results with the CONT/HALT key (i.e. the CONT/HALT key switches between the measurement states RUN and HLT; starting a measurement from the OFF state by means of the CONT/HALT key is not possible). In the HLT state, the instrument resources are not released; the application is still available. The formal aspects of measurement control are explained in Chapter 5.

− The softkey indicates the generator status (ON, OFF). A yellow triangle

indicates that a popup menu providing configurations can be opened with the softkey (press once for selection, a second time for opening the popup).

A generator can be started and aborted with the ON/OFF key. The formal aspects of generator control are explained in Chapter 5, section Measurement Control.

The softkey toggles between two hotkey bars (corresponding to two groups of settings). The current group is indicated in large typeface in the first line of the softkey; the alternative group appears in smaller typeface next to a double triangle.

Hotkeys

Hotkeys are assigned to the eight keys at the lower edge of the screen. Only the hotkeys softkeys which are actually assigned in a menu are indicated (see Fig. 3-1).

Selection:

A hotkey is activated by pressing the associated key. After activation it changes its frame.

Function:

Hotkeys permit to

− Change from one measurement menu/graphical measurement menu to the other

− Select tabs in the popup menu

− A yellow triangle indicates that a second version of the current tab

providing additional configurations can be opened with the hotkey. The hotkey toggles between the two versions of the tab.

In the graphical measurement menu (see page 3.7), hotkeys provide extended settings and can be used like ordinary function softkeys.

Operating Menus CMU

Operating Menus

The CMU offers a large variety of operating modes and applications. To ensure quick and easy operation, uniform menus have been implemented. They can be divided into three types:

Measurement menu Offers the most important settings controlling a measurement and displays the

main results.

Popup menu Provides extended settings for a measurement menu or function group. Graphical menu Displays a measurement trace together with settings and further measurement

results, contains softkeys and hotkeys used to access measurement control settings.

Measurement Menus

A measurement menu provides the basic settings controlling a measurement and at the same time displays the main results. Together with the graphical measurement menus, measurement menus constitute the basic level in the operating system of the CMU. They can only be replaced by other measurement menus or graphical measurement menus. To change the menu, the hotkeys at the lower edge of the measurement menu are used.
