Introduction
The Nine Fives Programmable SPDT Switch, Programmable SP4T Switch, and Programmable Attenuator are network-controlled RF instruments. Each device provides three communication interfaces for monitoring and control:
- Web UI (Port 80) — Browser-based graphical interface for configuration and control
- REST API (Port 80) — JSON API for integration with custom applications and automation scripts
- SCPI over TCP (Port 5025) — Industry-standard text protocol for test and measurement applications
- SCPI over HiSLIP (Port 4880) — High-Speed LAN Instrument Protocol (IVI-6.1) for VISA-compatible instrument communication
All interfaces provide equivalent control over the device. Choose the interface that best fits your application.
Device Variants
Nine Fives produces the following device variants:
| Variant | Description |
|---|---|
| Programmable SPDT Switch | RF switch with two throws (RF0 / RF1) |
| Programmable SP4T Switch | RF switch with four throws (RF0–RF3) |
| Programmable Attenuator | Variable RF attenuator (0–95.25 dB in 0.25 dB steps) |
See the SPDT, SP4T, or attenuator product specifications for RF performance, power limits, environmental ratings, and connector details.
All variants share common system, network, and firmware management capabilities. The variant-specific commands and endpoints are documented in their respective sections.
