1. Drive 50% of 1 V or 10 V output with a resistive load. Rise time is from 10% to 90% of program voltage change at maximum current. Fall time is from 90% to
10% of program voltage change at maximum current.
2. Measurements obtained are per default bandwidth setting.
NOTE
All channels are isolated from the ground and from each other. Isolation is +60 VDC, Category 1.
All specications are based on a three-hour warm-up time.
The measurement accuracy value is x (1 + a * y), where,
x = accuracy specication at room temperature,
a = temperature coefcient, and
y = temperature change from room temperature in °C
Noise 10 Hz to 20 MHz (Peak-peak)
