Radio Test Set
The family of Radiocommunication Service Monitors CMS comprises two models. These radio testers allow transmitter, receiver and duplex measurements to be performed on mobile radios, base stations or RF modules. The CMS family monitors are ideal radio testers for service, maintenance and test departments.
CMS – a test set replacing many individual measuring instruments
Due to the comprehensive standard configuration of the individual models and the optional extensions tailored to specific applications, external measuring instruments in addition to the CMS are not required.
Overview of models:
Basic features:
Transmitter and receiver testing
Spectrum monitor
Fully automatic testing
SSB test
CMS57 – the specialist for avionics
Basic features additionally with:
VOR/ILS signal generator
Overview of configurations (model-dependent or optional)
Signal sources
RF synthesizer from 0.4 to 1000 MHz, resolution 10 Hz, with AM, FM, φM and multitone modulation capabilities
Two independent modulation generators, from 20 Hz to 30 kHz each, resolution 0.1 Hz
Selective-call encoder to all standards (also user-programmable)
CDCSS coder
DTMF coder
10 MHz reference frequency input/output
VOR/ILS signal generator
Measuring facilities
RF frequency counter, RF frequency-offset counter
Power meter from 5 mW to 100 W
Selective RF power meter down to -100 dBm
RF spectrum monitor with wide dynamic range and filters which also allow modulation analysis (AM, FM, SSB)
Tracking generator in frequency range from 400 kHz to 1000 MHz
Adjacent-channel power meter with standard ETSI filters
Modulation meter for AM, FM and jM; weighting: +PK, -PK, PK HOLD, PK/2, RMS, RMS2
Duplex modulation meter for duplex spacings of any size
AF voltmeter with peak and true RMS weighting
SINAD meter with variable test frequency
S/N meter
Distortion meter with variable test frequency
AF frequency counter with period and gate-time counting
Selective-call decoder for all standards (also user-programmable)
DTMF decoder
CDCSS decoder
Oscilloscope
DC ammeter/voltmeter
Transient recorder for analysis of power and frequency transients
Cable fault test
Filters
CCITT or C-message filters for weighting to relevant standards
Continuously tunable bandpass filter from 50 Hz to 5 kHz with high skirt selectivity for selective modulation and AF measurement
Continuously tunable notch filter from 100 Hz to 5 kHz for signal suppression
Highpass and lowpass filters for band limiting and measurement of subaudio tones
Other facilities
Second RF input with high sensitivity for off-air measurements, can be used independently for module testing
Built-in 600 Ω AF transformers for modulation generator and AF voltmeter
Connector for battery (11 V to 32 V)
13 dBm RF output for off-air measurements
Memory for storing complete instrument setups
Automatic tests
Automatic test routines are indispensable for high throughput and reproducible results in service and production: in the learn mode, the Radiocommunication Service Monitor CMS stores all manual settings and measurements and produces from them ready-to-start automatic test routines. The user need not have any programming knowledge or learn equipment-specific command sets.
Tolerances, comments and conditions (loops, jumps, queries and control commands) can additionally be inserted into the test routines. Programs can also be activated directly from the memory card. The test report format may be user-specified and can be clearly structured by transferring control characters to the printer, such as blank line, paragraph and bold-face.
Options:
B1 = OCXO reference oscillator, aging : 2*10E-7/year
B5 = Control interface with CCITT filter, DTMF decoder and Centronics interface
B9 = Duplex modulation meter for CMS55/57 with ACP meter and tracking - See more at: http://www.testequipmentconnection.com/70068/Rohde_Schwarz_CMS57-B1-B5-B9.php#sthash.HGkmExrW.dpuf
