Pulse Energy Limit
(single or low repetition rate, Δ R<5%)
Pulse Energy Limit
(single or low repetition rate, Δ R<5%)
1.2/50μs Peak Voltage Limit
(10 pulses at 10s intervals, ΔR <5%)
Note the voltage shown is the nett voltage across the resistor. The generator
open circuit voltage will be higher due to the generator ’s internal impedence.
