Detail
  MR8740 MR8741
Number of channels [Block I: 16 analog units]
From 32 ch analog + 8 ch standard logic inputs
[Block I: 13 analog units + 3 logic units]
26 ch analog + 56 ch logic (8 ch standard logic + 48 ch logic unit)

[Block II: 11 analog units]
From 22 ch analog + 8 ch standard logic
[Block II: 8 analog units + 3 logic units]
16 ch analog + 56 ch logic (8 ch standard logic + 48 ch logic unit)
*Instrument consists of two blocks, Block I and Block II.
*Block I and Block II start measurement simultaneously by means of trigger synchronization (internal setting).
[8 analog units] From 16 ch analog + 16 ch standard logic
[5 analog units + 3 logic units] 10 ch analog + 64 ch logic (16 standard logic + 48 logic unit)
*Analog unit channels are isolated from each other and from chassis. Logic unit channels and standard logic terminal channels share a common GND with chassis.
