Product catalog summary

Product Overview: The document is a technical flyer for the R&S®RSG RF Step Attenuator, a product by Rohde & Schwarz GmbH & Co. KG. It provides detailed specifications and operational guidelines for the device.

Specifications: The RF Step Attenuator operates with an impedance of 50 Ω and supports a frequency range from DC to 5.2 GHz. It offers an attenuation range from 0 dB to 139 dB in 1 dB steps. The VSWR is specified as <1.1 + 0.2 × frequency in GHz for DC to 3.5 GHz and <1.8 for 3.5 GHz to 5.2 GHz. Attenuation uncertainty varies with frequency, with specific values provided for different ranges.

Performance: The device can handle a maximum continuous wave power of 1 W and a pulse power of 200 W for pulses <10 µs. It supports a maximum voltage of 150 V for pulses <10 µs and has a life expectancy of over 5 million switching cycles. Switching time is less than 25 ms.

Environmental and Power Requirements: The operating and permissible temperature range is 0 °C to +55 °C, with a storage temperature range of –40 °C to +70 °C. The power supply requirements are 100/120/220/240 V ±10 %, 47 Hz to 440 Hz, consuming 20 W. The device complies with various safety and electromagnetic compatibility standards.

Mechanical Specifications: The device is designed to withstand shocks of 30 g for 11 ms and vibrations of 2 g from 5 Hz to 55 Hz. It measures 435 mm × 103 mm × 359 mm and weighs 5.5 kg.

Ordering Information: The RF Step Attenuator is designated as R&S®RSG with order number 1009.4505.02. A matching pad, R&S®RAM, is also available with order number 358.5414.02.

Additional Notes: Specifications are valid under specific conditions, including a 30-minute warm-up time and adherence to calibration cycles. Typical and nominal values are provided, with typical values verified during final testing.
