Q 3: What is the relation between the available acquisition time and the media (recording
medium) space?
Answer The available time depends on Media space, a Data type, and a Channel Number.
The available time can be roughly estimated by the following formulas.
Sample time: Acquisition length = (media space – 4KB) / (used channel numbers x 2)
Peak time: Acquisition length = (media space – 4KB) / (used channel numbers x 4)
Maximum time of acquisition of 8Ch of 640MB data at sample time (acquisition length
39,999,750 data)

Q 4: A data cannot be saved in CSV format is not available with an insufficient media space
message.
Answer The file size for saving in CSV format is about five times larger than in binary format.
Use the media having enough space.

Q 5: A recording operation can be started when inputting a frequency exceeding external
synchronization clock specifications (10 kHz), but is this operation available?
Answer A memory external synchronization is recorded by a 1μs gating internal clock with an external
clock.
A recording operation is available with the sampling rate up to about 1μs, but the 1μs
maximum delay from an external clock develops. Therefore, inputting a fast clock may trigger

a waveform distortion. The value of this specification is provided the value that can neglect the
influence of a waveform distortion (1% or lower.)
Q 6: After the speed of recoding paper feeding is externally synchronized, a monitor waveform
is not displayed.
Answer Once the paper feeding speed is externally synchronized, a real-time monitor is externally
synchronized as well.
The input terminal of an external synchronization is dedicated to a paper feeding motor.
Therefore, for the monitor, the same clock signals must be input to the input terminal of
