Wavetek 5P127SS26 step attenuator

Product Description

Wavetek 5P127SS26 Programmable Step Attenuator (127 dB, 1 dB Steps)

This is a Wavetek 5P127SS26, a programmable RF step attenuator designed for precise signal level control in test and measurement systems. With a total attenuation range of 127 dB in 1 dB steps, it is commonly used with signal generators, spectrum analyzers, and RF test setups to simulate path loss or adjust signal strength. Sold AS IS for parts, repair, or integration into a compatible test system.

Key Specifications (Based on Model):

• Model: Wavetek 5P127SS26

• Attenuation Range: 0 to 127 dB

• Step Size: 1 dB

• Connectors: Likely Type N (N-female) or SMA on input/output

• Control Interface: Programmable via TTL/CMOS parallel binary code (may require a compatible controller)

• Frequency Range: Typically DC to 1 GHz or higher (specification dependent)

• Accuracy: Usually ±0.5 dB or better per step (not guaranteed in surplus condition)

• Power: Requires DC power supply (e.g., +5V, +12V) for control circuitry

Potential Uses:

• RF Test System Repair: Donor unit for restoring a Wavetek-based or compatible signal conditioning rack.

• Component Salvage: High-quality relay-switched attenuator pads, precision resistors, RF relays, and connector interfaces.

• Custom RF Setup: Integrate into a DIY signal generator, automated test bench, or calibration station.

• Educational Tool: For teaching RF attenuation, programmable instrument control, or signal integrity concepts.

Important Notes:

• Control Protocol Required: This attenuator is programmable, not manual. It requires a compatible digital control interface (binary-coded parallel input) to set attenuation levels.

• Power & Signal Integrity: Verify voltage requirements and ensure clean power to avoid damage to internal switching relays.

• Performance Not Guaranteed: Attenuation accuracy, repeatability, and frequency response are not verified in surplus condition.
