SPGU Module
SPGU is the pulse generator module designed for the semiconductor parametric test
application and provides the following key functions.
• Number of output channels: 2 channels per module
• Output impedance: 50 Ω
• Output level: 0 to ± 40 V (open load), ± 20 V (50 Ω load)
• SPGU operation mode (effective for all channels installed in B1500A):
PG (pulse generator) or ALWG (arbitrary linear waveform generator)
• Channel output operation mode:
Free run, count, or duration
• PG output mode:
2-level pulse, 3-level pulse, or DC bias. For each channel.
• Terminal voltage measurement and load impedance calculation
• Automatic level adjustment by using load impedance measured or specified
• Pulse switch, which is more durable than mechanical relays, and better suited for
frequent switching applications.
