Test and Measurement

Munich, Oct 02, 2013
R&S enhanced its existing SMW200A VSG(vector signal generator) by adding the R&S SMW-K540 option to provide envelope tracking feature.

We know that major part of amplifier power in smartphone is dissipated as heat. This unique envelope tracking feature increases the efficiency of the amplifier,due to the ability of amplifier supply voltage to track the RF signal envelope. Hence amplifier always operates in a range close to its instantaneous maximum output power.Users can delay the RF waveform and the envelope waveform relative to each other by +/-500 ns with 1 ps resolution.

R&S offers communication test equipments such as CMU200 and CMW500 which are widely used across the globe by standard developers to develop/test modem from scratch. These modems are based on GSM/WCDMA/LTE and other 3GPP standards.

R&S CMU200 features

CMU200 is a Universal Radio Communication Tester widely used for testing devices based on 3GPP WCDMA-FDD/HSPA/GSM/GPRS/EDGE and GSM-R standards, more>>

R&S CMW500 features

CMW500 is a Wideband Radio Communication Tester can be used for testing upto frequency of 6 GHz. Used by modem developers of GSM/WCDMA/LTE and other standards. Brochure can be downloaded from following link:
