Notes about Using the 16-CH Voltage Input Module (720220)
While normal voltage input modules have two main channels for analog input, the 16-CH voltage input module
has 16 sub channels for analog input. The 16-CH voltage input module samples the measured sub channels in
order.

• The 16-CH voltage input module uses only the odd main channels of the slot that it is inserted into. It cannot
use the slot’s even main channels.
• If you do not want to measure an individual sub channel, turn its input coupling off. Sub channels whose input
coupling has been turned off are not scanned.
• The maximum sample rate of the 16-CH voltage input module
is 200 kS/s (when only one sub channel is
measured). The maximum sample rate per sub channel varies depending on the main channel sample rate
and
the number of measured sub channels. For information about sample rates, see appendix 1 in the Getting
Started Guide, IM DL850E-03EN.
•
The sample rate that is displayed on the screen is the sample rate of the main channel.
• The record length of each sub channel varies depending on the
set record length
and the number of
measured sub channels.
Record length of each sub channel ≤ set record length/number of measured sub channels
• The timing of waveform acquisition is different for each sub channel, but all the sub channels are stored in the
acquisition memory as if they had been sampled at the same timing. This means that the sampling times of
the acquired waveform data are different from the sampling times of the actual applied waveforms.
