Rohde & Schwarz on a product roll

-March 04, 2013

A lot’s been coming out of R&D at Rohde & Schwarz of late. Within little more than a two-week period, the company has made several announcements, launching new products and capabilities. Seldom is a company so prolific.

The most recent announcement is that the R&S CMW500 wideband radio communication tester now supports TD-SCDMA signaling functionality with the R&S CMW-KS750 option. The R&S CMW500 is a one-box, multimode test solution for TD-LTE, TD-SCDMA and GSM mobile radio networks as well as for WLAN signaling.

 

3GPP Fading


Looking back at a handful of announcements, one, for example, is an integrated a 3GPP fading feature for its CMW500 wideband radio communication tester that enables test under real-world conditions. Smartphone and chipset manufacturers can now carry standard-compliant MIMO performance tests during LTE testing using a single instrument.

The module supports GSM and WCDMA standards. The capability eliminates the need for an additional instrument for fading simulation, which requires extra cabling and separate configuration, as well as level and delay correction. When integrating the R&S CMW – B510F module in the CMW500, configuration is possible directly from the menu of the tester. The solution simulates dynamic propagation conditions defined in the test cases of the 3GPP standard for LTE, WCDMA, HSPA, HSPA+, GSM and EGPRS.  Available now.

R&S ESRP EMI Test Receiver

Another example is the R&S ESRP EMI test receiver that, when used in the early stages of design, helps detect and eliminate EMC problems in components and instruments, speeding products into production. Designed for diagnostic and pre-compliance measurements in the 10 Hz to 7 GHz frequency range, the device is both a fast EMI test receiver and a full-featured spectrum analyzer.

The device provides two methods for measuring disturbance signals:
  • Fast, FFT-based time domain scan to measure conducted disturbances in the CISPR band B with quasi-peak weighing faster, by many orders of magnitude, compared to conventional EMI test receivers using traditional methods.
  • Traditional stepped frequency scan

The R&S ESRP is operated by a touchscreen featuring clearly structured measurement modes. With the press of a button, users can switch between modes and easily configure complex measurements and automated test sequences from the touchscreen. The R&S ESRP can remotely control simple automatic tests with the help of the R&S ES SCAN EMI software. The R&S EMC32 application software for automated test routines, including report generation, integrates the receiver into large-scale EMC systems with such additional components as mast, turntable and absorbing clamp/slideway systems and for the remote control of the components. The R&S ESRP can be operated without AC supply as it also runs on DC power, making it suitable for mobile use in vehicles or battery operation during open area testing. Available.

 

R&S CMW-KM051 option


Launching the first integrated end-to-end test solution with IP and protocol and statistic analysis for detailed assessment of data transmission on smartphones, Rohde & Schwarz, with its R&S CMW-KM051 option, its CNW500 wideband radio communication tester can now comprehensively analyze and test IP-based apps using ipoque’s deep packet inspection (DPI) engine. Using RF and application testing capabilities in a single instrument gives network operators and smartphone manufacturers the ability to rest how mobile phone applications affect wireless communication and mobile phone network performance.

 

The option enables the R&S CMW 500 to analyze and test IP-based apps, providing a way to qualify applications or optimize them. IP analysis is based on logging each IP data packet sent and received at the IP protocol level. Error sources are possible to identify given the following functions that are available for precise analysis:

 

  • List of active IP connections
  • TCP analysis
  • Lit of protocols used
  • Data volume statistics
  • Protocol name resolution
  • Triggering on IP events

 

Available. Contact company for additional information.

 


New options for the R&S SMBV100A and the R&S FSV
Tailoring its mid-range measuring instruments to handle WLAN signals in like with IEEE 802.11ac, with the R&S SMBV 100A and R&S FSV, WLAN chipset, components, and device manufacturers can generate and analyze signals with 100 MHz bandwidth, and do it easily.

 

The new options extend the baseband of the vector signal generator to 160 MHz, so that it alone in directly supporting high-speed modes for WLAN IEEE 802.11ac. The latest generation of the field-tested R&S FSV signal and spectrum analyzer can also be equipped with a demodulation bandwidth of 160 MHz and be used to record and demodulate a WLAN IEEE 802.11ac signal in its full bandwidth of up to 160 MHz. Both the R&S SMBV100A and the R&S FSV cover not only WLAN but also all important standards such as GSM/EDGE, 3GPP WCDMA, HSPA, LTE, NFC and Bluetooth.

The new options for the R&S SMBV100A and the R&S FSV for extending the baseband to 160 MHz as well as the R&S FSV-K91ac option for measurements in line with IEEE 802.11ac will be available soon.

 


Passive model of broadband probe added


The R&S RT ZZ80 is a rugged, passive broadband probe that was just added to the company’s portfolio. The cost-efficient probe offers a bandwidth of 8 GHz and is well suited for testing transmission lines with low impedance (20W to 100W). It can be used wherever the timing of fast signals must be measured accurately. Available.

 

Two models added to R&S FSH family


R&S added two models to its handheld spectrum analyzer family. The R&S FSH13 covers a 9 kHz to 13.6 GHz range and the R&S FSH20 covers up to 20 GHz. Both models feature an amplifier that can be activated. Compact, they integrate measurement functions that can be used to analyze transmit signals and interference, measure performance, and more. They support all common wireless communications standards. The devices can be used for microwave applications up to 13.6 GHz and 20 GHz, respectively and are able to measure disturbance signals in wireless communications networks, such as UMTS up to the fifth harmonic. They will be available in Q2 2013.
