Channels (Vertical)

Vertical parameters and specifications are generally dictated by the plug-in module used with the mainframe. Please refer to the specifications for the individual module used. The following refers to parameters that are plug-in independent.

Resolution: Up to 15 bits with averaging. Variable IF gain sets minimum resolution to better than or equal to 9 bits on all ranges.
