The Mini-Circuits RUDAT-6000-90, RUDAT-6000-110 and RCDAT-6000-110 are single-channel 1 MHz–6 GHz programmable RF attenuators with fine 0.25 dB attenuation steps.

The main selection differences are simple:

RUDAT-6000-90: 0–90 dB, USB + RS232

RUDAT-6000-110: 0–110 dB, USB + RS232

RCDAT-6000-110: 0–110 dB, USB + Ethernet

Choose the RUDAT-6000-90 for standard RF testing, the RUDAT-6000-110 when an additional 20 dB attenuation range is required, and the RCDAT-6000-110 for remote or network-controlled test systems.

Key Specifications

90dB vs 110dB: Which Attenuation Range Do You Need?

The RUDAT-6000-90 provides up to 90 dB attenuation and is sufficient for many standard signal-level control applications, including receiver testing, Wi-Fi testing, LTE/5G FR1 testing and laboratory instrumentation.

The RUDAT-6000-110 and RCDAT-6000-110 extend the maximum attenuation to 110 dB.

The additional 20 dB is useful for:

Receiver sensitivity testing

Wide-dynamic-range signal simulation

Fading and handover testing

Power-level cycling

High-isolation RF test paths

If your test system does not require more than 90 dB attenuation, the RUDAT-6000-90 is generally the simpler choice.

RUDAT vs RCDAT: RS232 or Ethernet?

This is the most important difference between the 110 dB models.

RUDAT-6000-110

The RUDAT-6000-110 provides USB and RS232 control. It is suitable for benchtop equipment, direct PC control and automated test systems that already use serial interfaces.

RCDAT-6000-110

The RCDAT-6000-110 provides USB and Ethernet control, making it better suited to remote laboratories, production test racks and network-controlled ATE systems.

Mini-Circuits provides Ethernet automation support using HTTP, Telnet and SSH, as well as USB APIs and programming examples for Python, LabVIEW, C#, VB and MATLAB.

Conclusion

The three Mini-Circuits programmable attenuators share the same 1 MHz–6 GHz frequency range and 0.25 dB step size, so selection mainly depends on attenuation range and control interface.

RUDAT-6000-90 → 90 dB + USB/RS232

Best for general laboratory, wireless and automated RF testing.

RUDAT-6000-110 → 110 dB + USB/RS232

Best when more attenuation range is required while retaining serial control.

RCDAT-6000-110 → 110 dB + USB/Ethernet

Best for remote, networked and production test systems.

For most buyers, the selection can therefore be reduced to two questions: Do you need 90 or 110 dB attenuation, and do you need RS232 or Ethernet control?

Frequently Asked Questions

What is the difference between RUDAT-6000-90 and RUDAT-6000-110?

Both cover 1 MHz–6 GHz, use 0.25 dB steps and support USB/RS232 control. The main difference is the attenuation range: 90 dB for RUDAT-6000-90 and 110 dB for RUDAT-6000-110.

What is the difference between RUDAT-6000-110 and RCDAT-6000-110?

Both provide 0–110 dB attenuation from 1 MHz to 6 GHz. The RUDAT-6000-110 supports USB and RS232, while the RCDAT-6000-110 supports USB and Ethernet.

Which model is better for remote RF testing?

The RCDAT-6000-110 is the better choice because its Ethernet interface allows control over a network and supports remote test-system integration.

Do these attenuators support Python control?

Yes. Mini-Circuits provides programmable attenuator software resources and examples for Python and other common test-automation environments.
