Maximum Recording Times
11.11 Maximum Recording Times
The maximum amount of time during which data can be stored in the instrument’s internal bu󰀨er
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 bu󰀨er memory (256 Mwords), 512 × 1024 × 1024.
*2: Data size as described in “11.9 File Size” (p. 395).
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 approx. 10% since they do not take into account
the size of waveform le headers. The fewer channels are recorded, the greater the maximum
recording time.
