Attenuator 114 RVA – Flann Microwave

The Flann 114 RVA is a commercial-grade, direct-reading rotary attenuator designed for use in millimetre-wave test sets.

– Main features:

• Calibrated dial: directly indicates the attenuation value.
• Precision helical drum scale: 10 turns, 75 mm diameter, offering high resolution and discrimination over an attenuation range of 0 dB to 40 dB.
• Reference-only measurements up to 60 dB.
• Negligible phase variation over the attenuation range.
• Robust mechanical design: minimises RF losses by throttling rotary joints, while ensuring no backlash in instruments.

Furthermore, by using high-value attenuation markings positioned symmetrically around the position of maximum attenuation, the user can easily verify the alignment of the attenuation characteristic, ensuring maximum confidence in the accuracy of subsequent measurements.

The Flann 114 RVA guarantees reliability and accuracy and is the ideal choice for your millimetre frequency testing.
