Rohde & Schwarz er einn stærðsti framleiðandi mælitækja í heiminum og er einn þeirra virtasti og má nefna að flestir aðrir framleiðendur nota mælitæki frá þeim til að stilla framleiðslu sína. Einnig eru þeir brautryðjendur nýjunga á fjarskiptasviði og vinna þar með Háskólum um viða veröld í þróun nýrrar tækni.
The R&S FSH3 is a handy, robust and portable spectrum analyzer for rapid and cost-effective signal investigations.
The Signal Analyzer R&S FSQ is based on the tried and tested R&S FSU family and extends the IQ demodulation bandwidth to 28 MHz, thus opening up new application areas.
The Signal Analyzer R&S FSQ combines two instruments in one:
- Spectrum analyzer with highest dynamic range available and wide resolution bandwidths; the RF performance is the same or better as that of the R&S FSU
- IQ demodulation with wide demodulation bandwidth of 28 MHz

Digital Radio Testers R&S CTS for mobile phones
Tester family for fast and conclusive GSM and DECT measurements in service
![]()
Characteristics
Digital Radio Tester CTS – the service tester family from Rohde & Schwarz – comes in four models:
- CTS30 for mobile phones GSM900/ 1800/ 1900 remote control only (no display)
- CTS55 for mobile phones to GSM900/ 1800/1900
- CTS60 for DECT phones (portable part and fixed part)
- CTS65 for GSM and DECT
Digital Radio Tester CTS is an extremely compact, modular yet powerful measuring instrument. It combines great ease of operation and the necessary test depth for use in all service areas for mobile and cordless phones: from a simple functional test to repairs. Both the newcomer and the service specialist will be able to conveniently carry out fast automatic functional tests as well as complex and comprehensive manual measurements down to component level.GSM measurement functions
- CTS55 simulates a GSM base station and can completely control the mobile for testingpurposes. The following measurements and tests can performed by automatic test routines or manually.
- Synchronization of mobile phone with base station (which is simulated by CTS)
- Location update
- Call establish (mobile originated/ mobile terminated)
- Call release (mobile originated/ mobile terminated)
- Power Control
- Measurement of transmitter power
- Handover (channel change)
- Sensitivity
- Bit error rate BER and RBER
- RxLev and RxQual
- Phase and frequency error
- Power ramp versus time (Power time template)
- Dual band handover
- Timing error
- Echo test (voice test, includes also testing of loudspeaker and microphone)
- Function test of mobile's keypad through display of dialled number
- Display of
- IMSI (international mobile subscriber identity)
- IMEI (international mobile equipment identity)
- GPRS signalling
- All coding schemes CS1 - 4
All this measurements can be found in 5 different modes of operation:
1. Go/ Nogo Test mode
2. Auto test mode
3. Manual test mode
4. Module test mode (optional)
5. Remote control (from an external PC (optional))
DECT measurement, test and adjustment capabilities
- Synchronization of DUT with the CTS
- Call establish
- Call release
- Echo test
- Detection and display of RFPI (FP)
- Normal transmit power (NTP)
- Power ramp versus time(Power time template)
- Modulation characteristics versus time
- Frequency offset
- Maximum modulation deviation
- Frequency drift
- Timing (jitter, packet delay)
- Bit error rate (BER), frame error rate (FER)
- GAP signalling (optional)
- IPUI detection (optional)
The DECT measurements are available in three different modes
- Auto test mode (free configurable)
- Manual test mode
- Remote control (from an external PC (optional))
Remote control with CTS-GO
CTS-Go is a free application software, which gives the user an example of the CTS capabilities, which are available under remote control. All above listed functions are accessable from an external Windows based PC via RS232 interface (requires option CTS-K6).
