PE70A8010

Overview

The PE70A8010 is a USB-controlled programmable attenuator manufactured by Pasternack. It provides a total attenuation range of 63 dB with 0.5 dB step resolution. The device operates within a frequency range from 200 MHz to 8 GHz. It utilizes SMA female connectors for signal interface and is designed for 50 Ohm impedance systems.

Feature Summary

• USB controlled programmability for remote adjustment
• High-resolution 0.5 dB attenuation steps
• Broadband operation up to 8 GHz

Applications

• Automated RF test and measurement systems
• Signal chain calibration and power control
• Telecommunications equipment testing

Procurement Notes

Verify the specific firmware version and USB communication protocol compatibility with your host controller before integration. Confirm that the SMA female interfaces align with your existing cable assemblies. Ensure the operating environment remains within the specified temperature limits to maintain accuracy.

Selection Notes

Select this model when precise, remotely adjustable attenuation is required in the 200 MHz to 8 GHz band. The 63 dB range and 0.5 dB steps offer fine control compared to fixed attenuators. Consider the USB interface requirement for system integration rather than manual rotary or push-button alternatives.

Part Context

This component belongs to Pasternack's line of connectorized attenuators. It differs from manual step attenuators like the PE70A1023 by offering electronic control via USB. It serves as an active element in test setups requiring dynamic signal level adjustment.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Manual alternatives such as the PE70A1023 (Rotary Step) or PE70A1047S (Push Button) exist but lack USB programmability.
