Using the GUI
The preferred way of controlling the Mt. Pleasant and Ceduna oscillators is now through the
The image below shows the script in operation
Each of the listed oscillators can be selected either by entering the full name as listed, or by the index number. The script will then prompt you for the desired frequency and level. It will then set the oscillator and refresh the display.
There are some caveats - the script requires the Field System to handle the GPIB communications correctly. It currently returns zero frequencies and power levels if the device is uncontactable (off at the power switch of not connected to the GPIB network). It also occasionally misreads a line but this can be corrected by refreshing the display.
If you wish to turn off the RF output, you can do this by sending “off” as the level. Similarly, you can turn the output back on by sending “on”
Control of the Agilent (first LO) and remote control of the second LOs (SML01, SMY01) is currently handled by some shell scripts on
To change the oscillator’s settings use
If you’re present at Mt Pleasant it is also possible to adjust the second LOs (SML01, SMY01) manually. They are located in rack 5. To adjust the frequency, press the FREQ button (to the right of the screen), type in the frequency in MHz and finally press the MHZ button to activate the new setting. For level adjustment, select LEVEL, enter the level in dBm & press the dBm button to activate the new setting.
N.B. For single frequency (dual pol) experiments, SML01 and SML02 should be set to the same frequencies
