SG-G1S-B3-01 Modular RF Signal Generator
The ETL Systems SG-G1S-B3-01 is a modular RF signal generator covering 25–3000 MHz in 100 Hz frequency steps. It provides adjustable output power from −15 to +13 dBm, with 0.5 dB adjustment steps and a specified step tolerance of ±0.2 dB.
The module features an SMA female RF connector, 10 MHz reference input and 100 MHz reference output. Internal reference stability is ±1 ppm. Frequency lock time is less than 50 ms.
Designed for a compatible GENUS 1U or Instrumentation Benchtop Chassis, each module occupies four slots. Local and remote monitoring and control are provided through the selected chassis, with touchscreen operation where fitted and web browser access through the chassis Ethernet interface.

Configuration and Ordering Notes
This listing covers one SG-G1S-B3-01 signal generator module. The compatible chassis, external reference source, cables and other accessories are sold separately unless included in the quoted configuration.
The V1.0 datasheet contains overview callouts referring to 50–2500 MHz, noise power spectral density and attenuation ranges that conflict with its signal generator specification table. This listing uses the 25–3000 MHz frequency range, −15 to +13 dBm output power range and other values in the dedicated signal generator RF parameter table.
The module and chassis have different environmental ratings. The complete system must operate within the limits of all installed components. Confirm the complete ordering suffix, chassis configuration and the meaning of the datasheet's “Power selection: Automatic switching” entry when requesting a quotation.
