RF test automation guides

Build a repeatable RF bench with clear specifications, documented commands, and measurements you can reproduce. These guides connect the Nine Fives attenuator and switches to common engineering tasks.

Program a signal-level sweep

Automate RF attenuation in Python: connect through Ethernet or USB-C networking, validate setpoints, read them back, and log the control sequence. Understand what the API confirms and what still requires an RF measurement.

Select the right switch topology

SPDT vs. SP4T for an automated RF bench: choose between two and four selectable paths, account for insertion loss and isolation, and issue model-specific REST or SCPI commands.

Compare programmable attenuators

Choosing an Ethernet-controlled programmable attenuator: compare the POE-ATTEN-6G with specific Mini-Circuits and Vaunix models using manufacturer documentation and explicit tradeoffs.

Characterize the complete signal path

Measure insertion loss, relative attenuation, and repeatability: plan reference-plane calibration, noise-floor checks, and data capture before treating a commanded value as a measured result.
