| == DBBC Configuration == | == DBBC Configuration == | ||
| - | The Digital Base-Band Converter (DBBC) takes the IF signals from the telescope and digitises them for the Mark5 recorder. The DBBC needs to be properly configured prior to an observation. Check that the DBBC is healthy and the server software is running: | ||
| - | * [[operations:documentation.DBBCSetupIVS_9.10.5|DBBC Setup]] | ||
| - | To configure the DBBC with the correct IF and frequency settings, use the following command | + | The DBBC should already be running and the PCFS should be able to communicate with it. |
| - | <code> | + | |
| - | setupsx | + | |
| - | </code> | + | |
| - | You can compare the DBBC IF and Frequency settings with the scheduled ones by comparing the setup in the printed procedure file with the values reported by the Field System.

| + | > * [[operations:documentation.DBBCSetupIVS_9.10.5|DBBC Setup]] | ||
| + | |||
| + | At the start of every scan, the pcfs executes the ''setupsx'' which sets the DBBC input channels, filters and BBC frequencies (and configues the Mark5). However, it's a good idea to execute it now so that a recorder test can be made: | ||
| + | * For R1, R4, RD, RDV, T2, ANZ, CRDS, CRF, OHIG:<code>setupsx</code> | ||
| + | |||
| + | ''setupsx'' calls ''ifdsx'' which sets up the DBBC Conditioning module inputs, filters and power levels, then ''dbbcsx8'' (or ''dbbcsx4'' for a 4 MHz DBBC mode) which sets the BBC frequencies. Then if you type: | ||
| <code>iread</code> | <code>iread</code> | ||
| - | BBC Settings: | + | You will see what the current Conditioning module settings are. Output format is: |
| + | <code><time>/<Module label>/<IF input number>,<Auto or Manual gain control>,<Nyquist filter number>,<Target power level>,<attenuation>,<actual power level></code> | ||
| + | Check there’s agreement with what appears in ifdsx. The actual power level should agree pretty well with the target level. The attenuation number can be anywhere between 0 (none) and 63 (maximum). If you see it at 0 or 63, it means the Conditioning module is having trouble getting the power to the right level. You may want to contact the on-call person in this case for help on getting the levels in range. | ||
| + | |||
| + | Then type: | ||
| <code>bread</code> | <code>bread</code> | ||
| + | You will see what the DBBC has set the BBC freqs to (compare with the .prc file). Output looks like this: | ||
| + | <code><time>/<bbc name>/<Frequency (MHz)>/<Conditioning module in use>,<Bandwidth (MHz)>,...</code> | ||
| + | the Frequency, Conditioning module label and bandwidth should agree with the listing in ''dbbcsx8'' (or ''dbbcsx4''). | ||
