| Acronym | Meaning | ||
|---|---|---|---|
| DBBC | Digital Base-Band Converter. Takes IF signals from the antenna and preforms filtering, tuning and digitisation of bands, then sends them to the Mark5 for recording | ||
| Mark5 | Data recording equipment. Takes digitised data from the DBBC and records it to one of two possible disk modules | ||
| IF | Intermediate Frequency. A signal mixed down to a lower frequency from its original RF (Radio Frequency) | ||

| CNS II clock | Takes signal from GPS antenna and provides a 1 PPS for comparison to other time sources (e.g. the maser) using the counters. Also provides time via a NTP server on cnss[hb | ke | yg] |
| KVM | Keyboard, Video, Mouse. A switch box that takes keyboard, video and mouse inputs from multiple PCs and allows the user to switch between them and interact with the PC from a single location. The KVM switches at the sites are networked so that a remote user can connect to a computer at the console level | ||

| SML | Signal generator. Each site is equipped with a Rhode & Schwartz SML signal generator to generate test signals | ||
| IF Unit | Takes the four IFs from the antenna (S and X band, LCP and RCP) and provides amplification and attenuation before splitting the signal to go to the DBBC, power sensor and spectrum analyser | ||
| PPS | Pulse Per Second. Refers to the 1 second time-ticks distributed to various instruments around the sites |
