Rohde & Schwarz SML Series RF Signal Generators
3 models with full specifications from Rohde & Schwarz.
The Rohde & Schwarz SML Series consists of compact, general-purpose RF signal generators engineered for development, service, and production environments. Operating from a minimum frequency of 9 kHz, these instruments provide high level accuracy, fast switching speeds, and diverse analog modulation capabilities. The series includes three main models: the SML01, the SML02, and the SML03. While they share core performance characteristics, such as a 0.1 Hz frequency resolution and digital frequency and level sweeps, they are distinguished primarily by their maximum frequency limits, ranging from 1.1 GHz to 3.3 GHz. This technical overview helps engineers and buyers select the appropriate SML generator based on their specific frequency coverage and hardware requirements.

Frequency Range and Capabilities
The primary differentiator across the SML family is the upper frequency limit. The Rohde & Schwarz SML01 covers a frequency range of 9 kHz to 1.1 GHz. The Rohde & Schwarz SML02 extends this range up to 2.2 GHz, while the Rohde & Schwarz SML03 offers the widest coverage, reaching up to 3.3 GHz.
All three models feature a fine frequency resolution of 0.1 Hz and support digital frequency and level sweeps, making them suitable for precise component testing and system characterization.
Output Power and Level Control
Each instrument delivers a standard maximum output power of +13 dBm. The Rohde & Schwarz SML01 and Rohde & Schwarz SML02 feature an output power range starting down at -140 dBm, with the SML02 allowing an overrange capability up to +19 dBm. To ensure long-term reliability and precise level adjustments under heavy usage, the Rohde & Schwarz SML03 utilizes an electronic attenuator.
Modulation and Reference Oscillators
The SML series provides flexible analog modulation, including amplitude modulation (AM), frequency modulation (FM), and phase modulation (\u03c6M), alongside an optional pulse modulation capability.
For reference, the Rohde & Schwarz SML01 uses a standard internal 10 MHz oscillator, and the Rohde & Schwarz SML02 includes a temperature-compensated crystal oscillator (TCXO) with the option to upgrade to an oven-controlled crystal oscillator (OCXO, SML-B1).
Frequently asked questions
- What are the physical dimensions and weight of the SML series?
- The SML01 and SML02 models measure 427 mm \u00d7 88 mm \u00d7 450 mm and weigh approximately 8.5 kg (less than 8.5 kg for the SML01).
- Can the SML series store custom instrument configurations?
- Yes. The Rohde & Schwarz SML01 features a save/recall memory capable of holding up to 50 complete instrument settings.
