MWAX 128T
The following are all the modes possible with MWAX configured with:
- 128T (16 RRI receivers)
- 24 x 1.28 MHz non-oversampled coarse channels
- No fringe-stopping enabled
Voltage Capture (VCS)
| Modes | GB/s | TB/hr |
|---|---|---|
| Voltage Capture (VCS) @ 0.781 μs critically sampled | 15.9 | 57.24 |
Correlator
Legend:
The value in each cell is the total of all data from all coarse channels, in gigabytes, generated in 1 second (GB/s). Multiply by the duration of your observation to get total size of your observation in the mode chosen.
| Blue cells | Supported | Modes identical to the legacy correlator |
| Green cells | Supported | Modes which are new to MWA and which are supported |
| Orange cells | Unsupported | Modes which take much more than 8 seconds to process 8 seconds of input data, or which generate more than 100 Gbp/s (thus not sustainable), and thus not selectable normally |
| Yellow cells | Limited support | Modes which take more than 8 seconds to process 8 seconds of input data but can be sustained for a limited duration |
Note: when in extended / long baseline configuration, most science cases will require the 10 kHz, 0.5 sec mode at a minimum until the fringe stopping feature is enabled
