Three parameters are needed to calculate the length of data that can be stored: disk size, acquisition rate and number of FBG.
For SmartScan USB data is stored in a raw format.
For 32 FBGs at 2,500 Hz, 100 minutes of data can be stored per GByte of disk space; this can be scaled proportionally to number of FBGs or acquisition rate.
E.g., for 16 FBGs at 2,500 Hz, 200 minutes / GByte
E.g., for 32 FBGs at 500 Hz, 500 minutes / GByte
E.g., for 16 FBGs at 250 Hz, 2,000 minutes / GByte
For SmartScope, data would likely be processed into measurement units, so it would be in the same format as files saved by SmartSoft, in which case each measurement uses 10 bytes, plus 10 bytes for the timestamp.
E.g., 32 FBGs = 330 bytes per sample
E.g., 16 FBGs = 170 bytes per sample
E.g., 1 FBG = 20 bytes per sample
E.g., 32 FBGs at 5 Hz = 10,000 minutes / GByte
E.g., 16 FBGs at 5 Hz = 20,000 minutes / GByte
E.g., 32 FBGs at 1 Hz = 50,000 minutes / GByte
E.g., 1 FBG at 1 Hz = 800,000 minutes / GByte or about 18 months / GByte
