Please pay attention that most of the standard GHz range coaxial
attenuators are not suitable for direct registration of output pulses
because of extremely high peak power. Even 100W and more power
attenuators will be broken inevitably. We recommend using of 142 series
Barth Electronics attenuator (for the frequencies below 5 kHz) as the first
attenuator connected just to the generator output or use a high voltage
directional coupler.
The generator is designed for the long time operation at the max repetition rate.
But it can be overheated in the case of unmatched load and high ambient
temperature. Please provide free airflow around the generator for a good cooling.
The temperature of the generator should be below 55 °C. Reduce the repetition
rate and/or improve the airflow if overheating occurs.
If the frequency of the triggering pulses is too high, then the red LED
“OVERLOAD” lights on and the generator stops the operation. Please reduce the
frequency of the triggering pulses, LED “OVERLOAD” lights off and the
generator continues the operation automatically.
