10.4. HD Recording Specifications
10.4.1. Recording File Size Calculation
This section covers how to calculate file capacity in HD recording. The file size can be calc
ulated using the following parameters.
Parameter
Recording length
Data type
Recording channel count
Recording information
File size = Acquisition information + (Data type x Acquisition channel)
Example: Recording length = 100,000, Data format = peak, Number of recording channel: 16
Size = 8,192 + (100,000 x 4 x 16) = 6,408,192 (bytes)
10.4.2. Recording Speed Execution Restriction
The following restriction may be subjected in settable range in HD recording rate depending on the
data format and the number of recording channels

Remark
Recording data count
One data is saved in two bytes.
Peak: 4 bytes due to two values (max. and min.)
Sampling: 2 bytes due to instantaneous value
Number of channels whose recording operation is set to ON (or
GND). If event inputs are targeted, two channels is available in each
channel.
Recording information save size: 8,192 bytes
* Size may be increased in future as the design is based on the
assumption of future expansion.
