+ | ===== Test Recording ===== | ||
+ | |||
+ | Now make a test recording using the Mark5. This is done through the Operator Input window. | ||
+ | |||
+ | <code>disk_record=on | ||
+ | mk5=dot? (Output should appear as before, but it should say FHG_on) | ||
+ | disk_record=off</code> | ||
+ | Now check the data are OK: | ||
+ | <code>scan_check</code> | ||
+ | Check the last numbers are the correct date at the start of the scan, duration, the data rate (should be 256 for the 8MHz mode, 128 for the 4 MHz mode) and 0 at the end for no problems. Then plot an autocorrelation from the data: | ||
+ | <code>postob</code> | ||
+ | The output should appear in the pcfs[hb|ke|yg] VNC session. Good data should contain quite flat bandpasses and zero phase. See [[operations:monitoring_autocor|autocorrelation spectra plots]] for an example and what problems to look out for. If there's a problem, the DBBC may need reconfiguring. | ||
+ | |||
+ | To clear the disk module, ONLY IF YOU'RE CERTAIN there is no data already on the disk! | ||
+ | <code> mk5=protect=off; mk5=reset=erase </code> | ||
+ | [[operations:monitoring_autocor|Check that the spectra are OK]]. | ||
+ | If there are dropped or strange-looking bands, the [[hardware:dbbc.reprogram|DBBC may need reprogramming]]. | ||
