  • 2 Radiocommunication Service Monitor CMS

    The Radiocommunication ServiceMonitor CMS from Rohde & Schwarzis the ideal radio tester for use in serv-ice, maintenance and test depart-ments. It is suitable for all transceiversusing AM, FM or M as well as SSB.

    Optional extensions enable the CMSto satisfy all requirements of radiomeasurements and even to cover relat-ed fields.

    Low weight, compact size and lowpower consumption make this instru-ment particularly suitable for mobileuse. Whether stationary or mobile, theCMS with its extensive test facilities al-ways provides a valuable service.

    The CMS uses a high-contrast, backlitLCD screen with high resolution and isoperated via softkeys. A clear menustructure allows fast and direct accessto all measurement facilities.

    With the autorun control and printerinterface, automatic test routines caneasily be configured and stored viathe front-panel keypad. Tolerancescan be inserted into these test routinesto determine and log pass/fail limits.

    Battery-backed memory cards areused as program and test report li-brary. Test reports, program lists andscreen hardcopies can be output on aprinter.

  • 4 Radiocommunication Service Monitor CMS

    CMS a test set replacing many individual measuring instruments

    Due to the comprehensive standardconfiguration of the individual modelsand the optional extensions tailored tospecific applications, external measur-ing instruments in addition to the CMSare not required.

    Signal sources RF synthesizer from 0.4 tMHz o

    1000 MHz, resolution 10 Hz, with AM, FM, jM and multitone modula-tion capabilities

    Two independent modulation gen-erators, 20 Hz to 30 kHz each, resolution 0.1 Hz

    Selective-call coder for all stand-ards (also user-programmable)

    CDCSS coder DTMF coder 10-MHz reference frequency

    input/output VOR/ILS signal generator

    Signalling unit NMT 450, NMT 900 (SIS), NMT

    450 I, E-TACS, J-TACS, N-TACS, TACS II, C-Net, N-AMPS, E-AMPS, Radiocom 2000, POCSAG

    Measuring facilities RF frequency counter, RF frequen-

    cy-offset counter RF power meter from 1 mW to

    100 W Selective RF power meter down to

    100 dBm RF spectrum monitor with wide dy-

    namic range and filters which also allow modulation analysis (AM, FM, SSB)

    Tracking generator in frequency range 400 kHz to 1000 MHz

    Versatile fields of application ... ((WF 39 787-1))

    ... on-siteThe Radiocommunication ServiceMonitor CMS is a rugged and handyunit that is particularly suitable for mo-bile use. It can be supplied from the lo-cal DC voltage (long operating timesthanks to low power consumption).The results of the automatic transceivertest can be stored on a memory cardfor later analysis and printout.

    Ease of operation, automatic preset-tings and test routines as well as cleardisplay of all parameters ensure effi-cient measurements.

    ((WF 39791-1))

    ((WF 39 785-3)) ... in developmentThe CMS offers great benefits to the de-velopment engineer: it combines in aminimum of space RF and AF genera-tors as well as analyzers with high accu-racy and wide dynamic range. In par-ticular the CMS54 features measure-ment capabilities, such as measurementof frequency/power transients of mo-bile phones, base stations or RF mod-ules, which usually require a compre-hensive set of measuring instruments.

    ... in productionThe CMS can be used in productionenvironments both for module testingand for final system testing withoutany restriction. The built-in autoruncontrol allows modules to be testedand adjusted without the need for anexternal controller, the results beinglogged at the same time. The CMS canalso be integrated into larger test sys-tems via the IEC/IEEE bus, short meas-urement times in pre- and final testingbeing obtained as a result.

    Connector for battery (11V to 32 V) 13-dBm RF output for off-air meas-

    urements Memory for storing complete in-

    strument setups Carrier bag

    Automatic tests

    Automatic test routines are indispensa-ble for high throughput and reproduc-ible results in service and production:in the learn mode, the Radiocommuni-cation Service Monitor CMS stores allmanual settings and measurementsand produces from them ready-to-startautomatic test routines.

    The user need not have any program-ming knowledge or learn equip-ment-specific command sets.

    Tolerances, comments and conditions(loops, jumps, queries and controlcommands) can additionally be insert-ed into these test routines. Programscan also be activated directly from thememory card.

    The test report format may be us-er-specified and can be clearly struc-tured by transferring control charac-ters to the printer, such as blank line,paragraph and bold-face.

    ((WF 39834))

    Test routines, results and memory card contents can be logged on a directly connectible printer
