Suppose we want to receive data from a spectrum analyzer located at a remote site, connected over a VSAT network? Could a probe be used to store the data remotely and then synchronize the probe data with the central site?
Could DataMiner offer a solution here? The challenge is that, in ASM mode, the spectrum analyzer should send data every 300ms. But that’s not possible over satellite links because of known delays in satellite transmission. So, maybe we can think of a solution where a probe could store the real-time data and send the data to a central location. Thanks in advance.
The delay of Satellite link is the concern – thus the central NMS of spectrum analyzer can not have sufficient data.
Hi Pramod,
Spectrum monitors can probably provide a solution here. A monitor will periodically run a script that takes data from the spectrum analyzer. Also, it can do some analysis on this data, e.g. calculate SNR average over 10 traces. This SNR value can then be displayed and monitored like a normal parameter. The traces used for this calculation can be stored as a recording.
When using probes, it should then be possible to have a view on this data by using element linking to link an element on the probe to an element on a central system.
I'm not sure if this has ever been implemented or tested with spectrum elements and spectrum monitors before, so this would need to be tested.
Is the delay of the satellite link the concern or the bandwidth utilization? And what kind of bandwidth utilization would be acceptable?
