System description
This Pulse IV system is used to bias transistors in quasi-isothermal conditions, it enables accurate compact modeling activities.
Pulser Safe Operating Area
Emergency stop when the operating point exceeds design limits: Ip, Irms, Idc (pulsed, RMS and DC current), Vdc (pulser input voltage, drain pulser only), Pmax (DC power), Fmax (switching frequency), Temperature.
Current Breaker
Programmable thresholds: pulse current and power, quiescent current and power, transient current
Measurement Sampling Time
Fully programmable, 20ns resolution, External synchronization Mtrig & Rfpulse
Modularity
The standard system works with two pulse generators and one control box. External signals permit to combine and synchronize several control boxes (4, 6, 8…).
