Specifications

The 1240/1241 provide up to 72 acquisition channels (one to four acquisition boards with 9 or 18 channels each) at acquisition speeds up to 100 MHz asynchronous or 50 MHz synchronous, 14 levels of triggering with conditional branching.

Internals

The power supply is a switch-mode supply that mainly generates 5 V at up to 45 A. It requires a minimum load of 11.6 A. Additionally it generates 3 V at up to 8 A with no minimum load and several other voltages that are derived from linear post regulators.

Boards are two to six layers.
