I’m trying to make a radiometric calibration of the data of the SENTINEL-1 IW Level-1 SLC product. I’m using a desktop SNAP application. My computer configuration is Intel Core™ i7-4510U CPU@ 2.00 GHz 2.60 GHz, with 16,00 Gb of RAM. The process simply not working. Anyone can help me? Thanks a lot.
Maybe your product wasn’t downloaded (or unzipped) completely? Is the file size reasonable?
You can apply calibration directly on the zip file.
Thanks a lof for your answer. The product was donwloaded completely. It have a size of around of 4,5 GB. I’m applying calibration directly on zip file in the SNAP…
can you please provide us the id of the image so we can try?

I tried to make the same operation in other two computers with respective configurations:(i) Intel Core I5 7200U CPU 2.50 GHz 2.70 GHz with 8 Gb RAM, (ii) Intel Core I7 3770 CPU 3.40 GHz 3.40 GHz with 8 Gb RAM. On both computers it did not work. It exhibited the following error message.
I suspect it is a SNAP configuration problem. Can someone help me? Thank you very much.
Have you installed the 64 bit version of SNAP? This makes s clear difference.
You also have to make sure that SNAP makes full use of the RAM
