Marconi 2024

The Marconi 2024 device driver is a Signal Generator which is supported by RadiMation^®.  

Configuration

The following tabs are available in the advanced configuration of the Marconi 2024:

The frequency range of the Marconi 2024 as provided by the manufacturer is shown and selected as default. It is possible to overrule these frequencies and to manual adjust the allowed frequency range of the Marconi 2024.

Use default start frequency

If the checkbox is checked, the default start frequency will be used as the lowest usable frequency in a test for this device.

Custom start frequency

If the Use default start frequency checkbox is unchecked, another start frequency (expressed in MHz) can be specified. The customized start frequency will then be used as the lowest usable frequency in a test for this device. The customized frequency can be a limitation or an extension of the default start frequency.

Use default stop frequency

If the checkbox is checked, the default stop frequency will be used as the highest usable frequency in a test for this device.

Custom stop frequency

If the Use default stop frequency checkbox is unchecked, another stop frequency (expressed in MHz) can be specified. The customized stop frequency will then be used as the highest usable frequency in a test for this device. The customized frequency can be a limitation or an extension of the default stop frequency.

Specifying a different frequency range can be useful if for example:

• A device (like a coupler, antenna, injection device, cable, etc...) is still useable (but out of specification) outside the standard suggested frequency range.
• An external mixer is used to measure an extended frequency range.
• An up- or down-convertor is used to shift the frequency range.
• A newer model of a device is present that has an extended frequency range, and still uses the same remote control commands.

Be careful changing these setting as RadiMation^® is no longer able to verify if the Marconi 2024 is used outside frequency range that is specified by the manufacturer. This may result to serious damage of your measurement device.

Pulse Modulation

The 2024 does not have a internal connection from the low frequency generator to the PM modulator. PM Manual page

To overcome this problem, connect the low frequency generator en the external modulator with an bnc cable. this works for most of the 2024. some of them need additional hardware to generate the correct levels. with older machines this is the external Pulse modulation input. With newer machines this is Ext Pm / FSK input.

Error 451: Query unterminated

There is a known problem with the Marconi 2023 and 2024 generators, where they sometimes cannot keep up with the speed of the communication, and they are generating 'Timeout' and 'Query Unterminated' errors. Our RadiMation device drivers for the Marconi 2023 and 2024 are aware of this, and they are handling this correctly. The error is thus not reported to the end-user but it is visible on the display of the generator itself.
