The R&S SMB100B analogue RF signal generator and the R&S SMBV100B vector signal generator set new standards in their class, offering higher spectral purity, output power and easy, intuitive touchscreen operation for

The new systems build on the SMB100A (analogue model) and SMBV100A (vector model) that started the ¾ 19″ form factor and are available in various configurations. With frequency ranges from 8 kHz to 1 GHz, 3 GHz and 6 GHz, they can be tailored to address diverse applications. There are three RF output power stages to scale the maximum output power to their specific needs and the generators can deliver up to +34 dBm output power (at 1 GHz carrier frequency) without an external amplifier, which simplifies the test setup and eliminates downtime due to calibration. The R&S SMB100B and the R&S SMBV100B offer precise, calibrated RF output power for all configurations.

The R&S SMBV100B offers higher signal quality for vector-modulated signals, with a baseband section with up to 500 MHz bandwidth. It comes with options for all major digital communications standards, such as 5G, cellular IoT, LTE, WLAN IEEE 802.11a/b/g/n/ac/ax and Bluetooth 5.0. Signals for these digital standards can be generated directly on the instrument; no external PC is required. This makes it quick and easy to vary signals and parameters. The R&S SMBV100B also provides envelope tracking and digital predistortion (DPD). Signals with up to 2 GHz bandwidth can be modulated via external I/Q inputs. Internally generated 160 MHz WLAN IEEE 802.11ac signals exhibit a measured EVM as low as –49 dB. Wideband signals benefit from the generator’s excellent I/Q modulation frequency response of 0.1 dB (measured) across the entire 500 MHz bandwidth. All this helps developers ensure outstanding product quality even for wideband communications systems such as 5G. 

Upgrades can in most cases be added via software keycodes. For example, modulation standards, output power and, with the R&S SMBV100B vector model, even the RF frequency range and modulation bandwidth can be upgraded as needed without requiring customers to send in their instrument to a Rohde & Schwarz service center. This procedure is easy, saves time and money, and gives flexibility. 

The R&S SMB100B analogue RF signal generator and the R&S SMBV100B vector signal generator are now available from Rohde & Schwarz.
