Key facts
RF measurements and broadcast decoding capabilities in one tool with instant results
R&S®TSMx is the product family for state-of-the-art network scanners for drive and walk tests and includes the R&S®TSMS8, R&S®TSMA6B and R&S®TSME6 scanners. R&S®TSMx products passively capture data from the air interface, offering a pure and accurate view of RF performance and MIB/SIB/Layer 3 messages from the most popular technologies without needing to subscribe to network services.
5G NR support in FR1 up to 8.5 GHz and mmWave (17 to 53 GHz) with R&S®TSMS53DC
The R&S®TSMx is a future-proof hardware platform with an in-field upgrade available for 5G NR (including RedCap and FrMCS) sub 8.5 GHz and mmWave measurements. The additional hardware (R&S®TSME44DC/R;&S®TSMS53DC) needed to measure mmWave frequency bands can be installed for simplified measurement setups and reduced setup times. The system demodulates L3/SIB messages without SIM cards (Release 17).
5G New Radio
Automatically detect all bands and technologies
The R&S®TSMx detects active channels in a specified band. 5G NR (incl. RedCap), LTE (incl. LTE-M), UMTS, CDMA2000®/1xEV-DO, TETRA, P25 and NB-IoT networks are supported. A spectrum scan option to significantly speed up detection is also available. In this mode, channel lists no longer have to be set up before a measurement campaign. The measurement system dynamically identifies new channels and adds them to the workspace during drive tests.
Automatic channel detection (ACD)
Automatically estimate cell positions in all networks
During a drive test, R&S®ROMES software can use measurement data and GPS data from the R&S®TSMx to estimate the geographic positions of base stations. The calculation is fast and accurate. GSM, WCDMA, LTE, 5G NR, CDMA2000®/1xEVDO and TETRA networks are supported in parallel. This unique feature enables users to quickly generate a base station list for export or graphic display.
BTS position estimation
Network synchronization in the time domain is getting even more important since the introduction of 5G NR in TDD mode. R&S®TSMx drive and walk test scanners can measure the time of arrival offset between PPS pulses (or the internal receiver clock) and received 5G NR and LTE signal sequences to determine network synchronization quality. Measuring the time alignment error (TAE) for network components is a special network optimization task. Filters, cables, antenna arrays and signal processing modules are potential sources for added time delays. Deviation from the network timebase necessarily causes frequency drift. To measure the frequency accuracy for a 5G NR cell, R&S®TSMx scanners provide measurements of the precise SSB center frequency (accuracy within a few Hz).
The web based programming interface allows scanners to be quickly integrated into any third-party software, regardless of the operating system. Both mobile network testing and cellular network analysis use cases are supported. See the R&S®TSMX-API brochure in the download section for details.
A comprehensive range of accessories is available. Rohde & Schwarz offers wideband omnidirectional antennas with magnetic or fixed mounts for drive testing in the sub 8.5 GHz frequency range. The R&S®TSMS-OMN8 omnidirectional antenna fully meet requirements across the entire FR1 spectrum. The wide frequency coverage spans from 380 MHz (lower band) to 8.5 GHz (upper band), which makes it an ideal solution for the entire FR1 frequency spectrum and partly for FR3. The R&S®TSMS-OMN70 is a wideband omnidirectional antenna for mmWave applications with optimized walk and drive testing patterns. The R&S®TSMS-LMAGM from Rohde & Schwarz is a robust magnetic antenna mount specifically designed for drive testing applications. It is available in multiple variants to cover different frequency ranges (FR1 or FR2) and provides excellent compatibility with the in-house developed omnidirectional antennas.
Cellular vehicle-to-everything network testing
Cellular V2X is the new industry standard for vehicle connectivity, improved road safety and efficient traffic management. It enables direct communications between individual vehicles and between vehicles and network infrastructure such as road side units (RSU). The K36 option enables the R&S®TSMx to measure PC5 sidelink interface coverage and quality for reliable V2X communications.
The R&S®TSMS8 is the next generation of ultracompact, superwideband RF scanning receivers for the wide frequency range from 10 MHz to 8.5 GHz.. The ultracompact design and ultra-wide receiver bandwidth of up to 400 MHz, along with support for all major technologies, mean the R&S®TSMS8 can perform simultaneous measurements at unmatched speeds for efficient mobile network testing and network analysis for governments and regulators.
