Specifications
1. See “Maximum pulse width and duty cycle” in Pulse Source Supplemental
Characteristics for applicable maximum voltage and current.
2. Max current limitation: For 21 V/1.515 A and 6 V/3.03 A ranges, total max
current is limited by the table below for using 2 channels. Max current is
not limited for using 1 channel only.
Maximum current limitation
