At the other extreme, it would be possible to limit the ADO to just a single parameter for message passing, and require that applications deal directly with the WFG via commands in its own language. Clearly, neither of these extremes is desirable. Connect a formula to an event. Shared memory Access to scoreboard, scratchpad, RTDL display area, etc. WFG Measurements such as the latest WFG output value, loopback and readback values, readback frame identifiers.
Sawtooth feature Adds optional hysteresis sawtooth before DC ramp.
Other WFG Settings including readback mode selection, table-set index, faked event. The only obvious candidate for removal is the Sawtooth group. If mere reduction of the number of parameters was an important goal, then many could be combined into larger structures. However, this would introduce more complexity both to the ADO and to the applications, and is not recommended. Several parameters provide user-friendly methods of constructing formulas and tables for downloading.
