Maximum Recording Times
11.10 Maximum Recording Times
The maximum amount of time during which data can be stored in the instrument’s internal buffer
memory or on its storage media can be calculated as shown below.
If saving data in binary format, the maximum recording time can be calculated using the following
formula:
Maximum recording time = Recording capacity*
1
× recording interval (s) / data size*
2
*1: For the instrument’s internal buffer memory (256 Mwords), 512 × 1024 × 1024.
*2: Data size as described in “11.8 File Size” (p. 289).
Maximum recording times (rough estimates)
Example: Measuring 30 analog channels with 2 modules (no alarm output, no waveform
calculations)
Reduce the times shown in the following table by about 10% since they do not take into account
the size of waveform file headers. The fewer channels are recorded, the greater the maximum
recording time.
