HVSPGU - High Voltage SPGU

This section describes key specification of the high voltage semiconductor pulse
generator unit (SPGU) for Agilent B1500A. Maximum five modules can be
installed in one mainframe.
• Number of output channels: 2 channels per module
Output impedance: 50 
•
Output level: 0 to ± 40 V (open load), ± 20 V (50  load), 1 mV resolution
•
• SPGU operation mode:
PG (pulse generator) or ALWG (arbitrary linear waveform generator)
• Channel output operation mode:
Free run, duration, or pulse count (PG mode)/sequence count (ALWG mode)
• PG output mode:
2-level pulse or 3-level pulse, for each channel
• Pulse timing parameters: (programmable range)
Period: 20 ns to 10 s, 10 ns resolution
Width: 10 ns to period-10 ns, resolution 2.5 ns or 10 ns (transition time > 8 s)
Delay: 0 to period-20 ns, resolution 2.5 ns or 10 ns (transition time > 8 s)
Transition time (leading time or trailing time): 8 ns to 400 ms, resolution 2 ns or
8 ns (transition time > 8 ms)
• Pulse switch, which is more durable than mechanical relays, and better suited for
frequent switching applications.
• Automatic voltage level adjustment by specifying load impedance of DUT
