R&S adds instruments and wireless standards support

Rohde & Schwarz chose Electronica 2006 to debut its FMU36 spectrum and vector-signal analyzer, its NRP-Z81 broadband power sensor, and its R6240A DC voltage and current source/monitor. The company also announced support for UMTS LTE as well as PoC, MMS, and videotelephony.
The FMU36 targets chipset development for mobile phones and base stations. The instrument features a frequency range to 36 MHz to measure base-band I/Q signals, and it includes two analog inputs that can be operated either in balanced or unbalanced modes. It also provides the necessary sensitivity to serve low-frequency applications such as RFID or ADSL-modem measurements. The analyzer runs without an external PC. For use in measurement systems, it can be remote-controlled via GPIB or LAN.
The new NRP-Z81 broadband power sensor combines the RF detector, analog and digital signal processing, and scoring logic of a high-performance measurement instrument in a compact measuring head that can be directly remote-controlled via USB. Featuring a sampling rate of 80 million values per second, a video broadband of up to 30 MHz, and a rise time of 13 ns, the NRP-Z81 allows high-resolution envelope analyses. Complete statistical analysis of a signal can be performed within only a few milliseconds. For average power measurement, it provides a dynamic range of 80 dB. The instrument's frequency range from 50 MHz to 18 GHz makes it suitable for measurements on radar and mobile radio signals. The R&S NRP-Z81 sensor can be directly operated via a PC or in combination with the R&S NRP base unit.
With its new R6240A, Rohde & Schwarz adds a ±15-V four-quadrant power source for component and module tests. The instrument features setting resolutions of up to 100 µV/100 nA and measurement resolutions of up to 10 µV/10 nA. The R6240A offers pulse and pulse sweep functions to perform measurements on sensitive components without cooling. In the pulse mode, which minimizes DUT heating, users can set minimum pulse widths of 500 µsec with a resolution of 1 µsec. The unit features an integrated 5000-point trace and result memory as well as trigger capabilities.
UMTS LTE, PoC, and MMS support
Rohde & Schwarz also highlighted its support for support network operators who are upgrading their UMTS networks with high-speed downlink packet access (HSDPA), high-speed uplink packet access (HSUPA), and emerging 3GPP UMTS long-term evolution (LTE). The company demonstrated the use of its FSQ spectrum analyzer and SMU200A signal generator for analyzing and generating UMTS LTE signals. UMTS LTE service, the company reports, is scheduled to be launched in 2009.
Finally, the company also announced that it now provides Global Certification Forum (GCF)-specified test cases for push-to-talk over cellular (PoC), multimedia message service (MMS), and videotelephony functionality. The test cases work with the company’s CRTU protocol tester and the R&S CMU200 universal radio communication tester.
