Throughput disk function

■Throughput disk function
This function records the digitally converted input signal directly to the PC's hard drive, allowing for long-term storage of up to 4GB.
In addition to digital recording, it allows for secondary processing (offline analysis) while the data remains digital, enabling highly accurate analysis.
The recorded data can be quickly accessed at any given time using the marking function.
The file export function allows conversion to other formats such as WAV and DADiSP, enabling further processing with other application software.
<Maximum memory duration>
Throughput data collection capacity varies depending on the number of channels and frequency. It also depends on the PC. An example is shown below, but please consider it as a reference value.
(Note) The values listed are not guaranteed values.
PC specifications:
Desktop PC
Pentium II 400MHz or higher, 128MB or more of internal memory.
Assuming HDD write performance = 3 Mbytes/s
4GB storage time, assuming 16-bit data precision (in 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 a vehicle as long as the vibration is within 1G and the impact is within 30G.
