Rohde and Schwarz offers new FSP models with upper frequencies of 13 GHz and 30 GHz for GSM, microwave or radar applications. FSP13 is capable of testing spurious emissions stipulated in the GSM specifications and has a firmware to allow adjacent-channel power (ACP) measurement to the W-CDMA/third-generation partnership project (3GPP). The electronic attenuator for a spectrum analyzer increases the availability for use in production and allows a number of switching operations in a wear-and-tear-free setting range of 30 dB in 5 dB steps. The FSP can be connected to networks such as 100Base-T via the LAN interface.
