| - | As oper@mk5ya, first check if the dimino program is running (ps -ef | grep dim). If not, start it with "dimino -m0&". While your at the prompt, check that the ntp time is correct by running "ntpq", and then issuing the "peers" command. The offset and delay to tac32ho should be small (less than ~5 milliseconds). If it is not, then the best thing to do is to run "fmset" on pcfshb, set the time (with ".") and then sync the formatter ("s", followed by "y"). Exit from fmset as soon as you have finished. | + | If necessary, load a new module. Here are a couple of videos showing how to install and remove modules: |

| + | ===== Setting up and configuring the Mark5 software ===== | ||
| - | It's worthwhile making a test recording using the Mark5. To do this you can either use tstdimino on mk5ya or the fs. The instructions below are for the fs but to use them in tstdimino, omit the leading "mk5=". | + | Log in to mk5ya as oper:<code>ssh oper@mk5ya</code> |

| + | <code>dimino -m0&</code> | ||
| + | ===== Synchronising the Mark5 Clock ===== | ||
| + | |||
| + | The following steps are done through the Field System. If not already started, start the Field system software on pcfshb by starting a new terminal on pcfshb, and type: | ||
| + | <code>fs</code> | ||
| + | An ''oprin'' window will appear and Field System commands are typed here. | ||
| First set up the Mark5 recording mode. There are two ways to do this, but the best way is to use the experiment procedure file: | First set up the Mark5 recording mode. There are two ways to do this, but the best way is to use the experiment procedure file: | ||

| - | If you see something like ''syncerr_gt_3'' then ''fmset'' may need to be run again. Also check that the maser-GPS and delay through the DBBC are the same (to within 1 microsec) with the <code>clkoff</code> and <code>maserdelay</code> commands which read the Agilent counters. | + | |

| + | When the interface appears, type | ||
| + | <code>s</code> | ||
| + | then confirm with a | ||
| + | <code>y</code> | ||
| + | Following this, the clocks should all be synchronised and agree with UT. Press the [Esc] key to exit ''fmset''. | ||
| + | |||
| + | Now check that the maser-GPS and delay through the DBBC are the same (to within 1 microsec) with the <code>clkoff</code> and <code>maserdelay</code> commands which read the Agilent counters. | ||
| If one or both counters are not responding to these commands, you will see an error message like this <code>ERROR sp -4 GPIB Device time-out on response c2</code> To fix this, try re-setting the counters. In the ''oprin'' window, type <code>counter</code> and try the ''maserdelay'' and ''clkoff'' commands again. | If one or both counters are not responding to these commands, you will see an error message like this <code>ERROR sp -4 GPIB Device time-out on response c2</code> To fix this, try re-setting the counters.
