Rohde & Schwarz RF and Microwave Signal Generators

Rohde & Schwarz analog generators focus on high spectral purity, low phase noise, and precise level control. For cost-effective benchtop testing, the compact SMC100A covers 9 kHz to 3.2 GHz with a frequency setting time under 5 ms. In the mid-range category, the SMB100A offers versatile analog modulation up to 40 GHz, while the SMB100B covers up to 6 GHz with a frequency switching speed under 1.2 ms and an integrated 5-inch touchscreen.

For high-performance applications, the premium SMA100A (up to 6 GHz) delivers a typical phase noise of -135 dBc/Hz at a 1 GHz carrier with a 20 kHz offset. For higher-frequency R&D, the SMA100B spans up to 67 GHz, yielding pure output signals with typical phase noise below -132 dBc/Hz at 10 GHz (10 kHz offset) and exceptionally high power configurations up to +38 dBm.

In the microwave category, the SMF100A provides dedicated coverage up to 43.5 GHz with a typical SSB phase noise of -120 dBc at 10 GHz (10 kHz offset). This sits alongside legacy microwave sources such as the SMP02 (10 MHz to 20 GHz) and the SMR family, including the SMR20, SMR27, and SMR40, which offer reliable CW and pulse modulation up to 40 GHz.

Vector signal generators (VSGs) incorporate complex I/Q modulation for modern wireless, cellular, and aerospace testing. The flagship SMW200A is a modular platform operating up to 67 GHz. It supports up to two independent RF paths, an internal RF modulation bandwidth up to 2 GHz, and up to 2 Gsample of ARB memory. This setup natively supports advanced digital standards like 5G NR, LTE, and GNSS.

For mid-range vector testing, the SMBV100A provides a 9 kHz to 6 GHz range with an internal baseband generator bandwidth up to 120 MHz and an I/Q modulator bandwidth exceeding 500 MHz. The SMJ100A is another capable platform, delivering an internal baseband bandwidth up to 80 MHz and a 200 MHz I/Q RF bandwidth. For high-performance multi-path setups, the SMU200A supports up to two independent RF paths up to 6 GHz with a typical phase noise of -135 dBc/Hz (1 GHz carrier, 20 kHz offset).

When rack space and automation speed are critical, the headless SGT100A offers a 1/2 19-inch, 1 HU form factor operating up to 6 GHz. It is optimized specifically for automated manufacturing and test systems where a front-panel user interface is not required.

To feed vector modulators with raw analog or digital baseband components, Rohde & Schwarz provides dedicated arbitrary waveform and I/Q generators. The AFQ100A is a high-speed vector signal source featuring a variable sampling rate from 1 kHz to 300 MHz, a 14-bit DAC, and 32 MSamples of standard memory (expandable to 1 GSample with options).

For dual-channel requirements, the AMIQ03/04 family operates as a software-controlled baseband source with sampling rates up to 100 MSample/s and memory capacities of 4 MSamples (AMIQ03) or 16 MSamples (AMIQ04). In general-purpose bench environments, the AM300 arbitrary function generator provides two phase-coupled channels with a 100 MSa/s sampling rate, 14-bit vertical resolution, and 256K-point memory per channel, which can be used to generate analog I/Q signals to feed generators like the SM300 vector signal generator.
