The table below lists the specifications of the LWA full stations (LWA1 and LWA-SV).
| Specification | Details | Comment |
|---|---|---|
| Number of stands | 256 | Plus one outrigger antenna at 300m baseline |
| Frequency coverage ν | 3-88 MHz | |
| Number of beams | 4 | |
| Number of tunings | 2 per beam | |
| Number of polarizations, Npol | 2 per beam per tuning | |
| Bandwidth per beam, B | 19.6 MHz max | 16 MHz usable due to band edges |
| Declination range | -30° to 90° | |
| All sky transient mode TBS | 100-300 kHz bandwidth | Continuous observing all dipoles |
| All sky transient mode TBT | 75 MHz bandwidth | Periodic bursts observing all dipoles |
| Spectrometer | See table | Minimum channel width 7.8125 kHz |
| SEFD | 6 kJy | At zenith |
| Sensitivity Smin | 5 Jy | 5 sigma, 1 sec, 16MHz, zenith |
| Confusion noise (zenith)1 | 25 Jy/beam | for a 2° beam at 74 MHz, only theoretical estimate |
1 The confusion limit will be reached in about 1 msec using 8 MHz bandwidth. Longer integrations can be achieved for narrower bandwidths.
