EMC Technology P561H programmable attenuator

Product Description

EMC Technology P561H 6-Bit Programmable Step Attenuator

This is a high-frequency, programmable step attenuator designed for automated test and measurement systems. With 6-bit digital control, it provides 63 dB of total attenuation in 1 dB steps across a broad frequency range from DC to 18 GHz, making it suitable for signal level control in RF development, production test, and calibration applications.

Key Specifications:

• Model: P561H

• Attenuation: 0–63 dB in 1 dB steps (6-bit control)

• Frequency Range: DC – 18 GHz

• Control Interface: GPIB/IEEE-488 (primary), with optional parallel TTL

• Connectors: Type N (N) female (standard)

• Accuracy: Typically ±0.5 dB or better depending on frequency and attenuation state

• Switching Speed: Milliseconds (relay-based)

Applications:

• Automated RF Test Systems: Integrating into production or validation test racks for calibrated attenuation

• Receiver Testing: Simulating path loss for sensitivity and dynamic range measurements

• Signal Generator Control: Precisely adjusting output power of broadband sources

• Calibration Labs: Use as a programmable transfer standard
