Product overview

The R&S®SMB100A is a compact, versatile microwave signal generator reaching up to 40 GHz, extendable to 170 GHz with the R&S®SMZ frequency multipliers. It combines outstanding spectral purity with high output power: typical SSB phase noise of –128 dBc/Hz at 1 GHz and 20 kHz offset, and maximum output power of typ. +27 dBm. Its innovative DDS synthesizer architecture set a new standard in the midrange class, and it covers the analog modulation modes that matter — AM, FM/φM and pulse modulation — for development, production and service work. The instrument occupies just 2U in height and 3/4 of a 19 inch rack width, is the lightest in its class (12.75 GHz model) and has a very low cost of ownership, with LAN, USB and GPIB remote control and emulation of the command sets of several major signal generator brands.

Key features

  • Wide frequency range: 100 kHz to 40 GHz (four model options: 12.75 GHz / 20 GHz / 31.8 GHz / 40 GHz)
  • Outstanding SSB phase noise: typ. –128 dBc/Hz at 1 GHz / 20 kHz offset; the innovative DDS synthesizer architecture gives best-in-class phase noise at low frequencies
  • High output power: typ. max. +27 dBm (12.75 GHz model); high-power option available (R&S®SMB-B31)
  • Full analog modulation: AM, FM and φM as standard; optional pulse modulator (R&S®SMB-K21) with an ON/OFF ratio > 80 dB and typ. < 5 ns rise/fall time
  • The R&S®SMZ frequency multiplier family extends the frequency range to 170 GHz, correcting the multiplier's frequency response automatically so the pair operates like a single instrument
  • The 12.75 GHz model uses a wear-free electronic step attenuator and, with the reverse power protection option (R&S®SMB-B30), stands up to production environments
  • Fast switching: frequency setting time < 3 ms (SCPI mode) and < 1 ms in list mode; level setting time < 2.5 ms (SCPI) and < 1 ms in list mode
  • Closed-loop power control: with R&S®NRP-Zxx USB power sensors it compensates cabling loss and temperature drift in real time, so the DUT receives exactly the intended power
  • Command set emulation: emulates more than 30 instrument command sets, including Keysight/HP E442x, E443x, E8257, PSG, MXG, Aeroflex/IFR and Anritsu
  • Compact design: 2U high, ¾ 19" wide, maximum weight 6.9 kg; meets MIL-STD-810E vibration and shock requirements for aerospace and defense field use

Typical applications

  • Radar system test (X band, K band, with the pulse generator and pulse train functions)
  • Mobile communications development and production test (all ISM bands and the major mobile bands up to 12.75 GHz)
  • Satellite communications and antenna measurement (50 GHz to 170 GHz with the R&S®SMZ frequency multipliers)
  • Aerospace and defense (wide operating temperature range, MIL-STD-810E qualification, secure data erase support)
  • Low-noise receiver sensitivity test (high spectral purity and excellent shielding; a replacement for a fixed-frequency high-quality crystal oscillator)
  • Automated test systems (multiple remote control interfaces, command set emulation, 125 W power consumption suited to densely packed racks)
