*1. Maximum continuous power available is derated linearly from 100% of maximum at 40oC, to 75% of maximum at 55 oC.
*2. Conductance (S) = 1 / Resistance (Ω).
*3. The set level is 10 times larger than the slew rate in CCL mode.
*4. The actual transition time is defined as the time required for the input to change from 10% to 90% or from 90% to 10% of the programmed excursion.
*5. Transient frequency depends on the time for high/low level and rising/falling edge.
*6. Full remote control via RS232 with optional GPIB and USB.
