Model 765-HV | 400 MHz 400 ps Fast Rise Time High-Voltage Pulse Generator (up to ±50 V pp)
The Model 765-HV High-Voltage Pulse Generator, available in 1 or 2 channels, delivers fast rise times below 400 ps and pulse amplitudes up to ±50 Vpp into 50 Ohms, making it ideal for demanding high-voltage applications. Supporting up to 400 MHz repetition rates and pulse widths as narrow as 1 ns, the 765-HV provides exceptional control over both timing and amplitude domains. Each channel offers fully programmable amplitude, offset, delay, and width with 10 ps resolution and <15 ps jitter.
A 7-inch user friendly touchscreen and intuitive front-panel controls simplify setup and channel navigation, while the rotary encoder enables fine, real-time adjustments. The redesigned analog front end ensures precise edge transitions with minimal overshoot and ringing, even at maximum output. Whether used for semiconductor testing, radar systems, or high-energy physics research, the Model 765-HV combines power, precision, and ease of use. Pushing the limits of high-voltage pulse generation.
