Throughput Disk Function

Throughput Disk Function
It has the function to directly record digitally converted input signals onto the hard disk of a PC, allowing for a maximum storage of 4GB for long durations.
Not only can it record digitally, but it also allows for secondary processing (offline analysis function) while remaining digital, enabling high-precision analysis.
The recorded data can be quickly accessed at any point in time through the marking feature.
The file export feature allows conversion to other formats such as WAV and DADiSP, enabling secondary processing in other software applications.
Maximum time that can be remembered
The ability to collect throughput varies with the number of channels and frequency. It also depends on the PC. The following is an example, but please consider it as a reference value.
(Note) The values mentioned are not guaranteed.
PC specifications:
Desktop PC
Pentium II 400MHz or higher, internal memory 128MB or more
HDD write performance = 3Mbyte/s case
Possible storage time for 4GB, in the case of 16-bit data accuracy (unit: seconds)
| frequency range | 2ch | 4ch | 8ch | 16ch | 32ch |
|---|---|---|---|---|---|
| 40kHz | 3495s | 2621s | - | - | - |
| 20kHz | 6991s | 5243s | 3495s | - | - |
| 10kHz | 13981s | 10486s | 6991s | 4194s | - |
| 5kHz | 27962s | 20972s | 13981s | 8389s | 4660s |
| 1kHz | 139810s | 104858s | 69905s | 41943s | 23302s |
| 0.1kHz | 1398101s | 1048576s | 699051s | 419430s | 233017s |
The throughput function can be used in vehicles if the vibration is within 1G and the shock is within 30G.
