R&S CMU 200 Software Update and Version Management

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.

Note: When copying an installation version to a PCMCIA card or floppy, ensure that all folders

containing a base system version or network option (the lowest-level folders in Fig. 1-9

below) are in the root directory. Otherwise the R&S CMU will not be able to detect the

firmware and start the installation. If a Versions.new text file (see section File Versions.new on p. 1.27 ff.) is used, it must also be in the root directory of the external storage medium.

New software options must be enabled by means of a key code entered in the Setup –

Options menu (see Chapter 4 of the operating manual). This is necessary only once; all options remain enabled after a software update.

Installation of new firmware versions and the use of different applications and versions on the same instrument is made easier by the following tools:

• The R&S Remote Service Tool (see p. 1.19 ff.) transfers software versions to the instrument.

• The VersionManager (see p. 1.29 ff.) is designed to manage different software versions stored on

the instrument.

Installation instructions are also given in Chapter 1 of the operating manuals for the individual software options.

R&S Remote Service Tool

The R&S Remote Service Tool organizes the exchange of data between the R&S CMU and an external PC or laptop, in particular to:

• Copy software versions and install them on the R&S CMU.

• Copy or move data files (e.g. screenshots created with the Print menu of model R&S CMU).

• Send remote control commands to the instrument.

The tool is available for download on the CMU Customer Web (https://gloris.rohde-

schwarz.com/gloris/1cmp/cmucustomer/index.html). It consists of a single *.exe file which can be copied

to any directory. When the executable file is started (double-clicked), the R&S Remote Service Tool opens the following main application window.

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 Chapter 1 of the complete

operating manual).

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).

In contrast to the Activate software dialog, the software selection dialog 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

R&S CMU 200 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 this chapter and in Chapters 3 to 4 of the complete operating manual 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 of the operating manual.

A Short Tutorial on CMU Operation

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

Condensed Operating Instructions

1. Press the RESET key on the front panel to set the instrument to the default state before you config- ure a new measurement.

2. Press ENTER to confirm selections, even if No or Yes is displayed.

3. The MENU SELECT front panel key 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 softkeys to the right of the menus 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.

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)

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).

 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 of the operating manual 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.

Note: RF User Correction

In addition to the static external attenuation settings, the

CMU provides systematic, frequency and leveldependent correction mechanisms of the generated and measured RF power:

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

Chapter 4 of the operating manual

• In many function groups (e.g. the present RF group)

a frequency-dependent attenuation can be defined after pressing Ext. Att. Output or Ext. Att. Input twice.

• Global, frequency and level-dependent correction tables can be loaded using the VersionManager; see section RF User Correction in Chapter 1 of the complete R&S CMU operating manual.

 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.

 Markers

Markers are a graphical tool used to locate points on a trace and read out their coordinates. A reference marker and two delta markers may be defined in the Power menu.

The reference marker trace, the delta markers tween their position and the reference marker. All marker coordinates are shown in the two parameter lines above 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 improves but the time resolution deteriorates when the resolution bandwidth is reduced.

... on Step 5



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.



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

 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.
