Introduction

Measurement Modules

HVSPGU - High Voltage SPGU

This section describes key specification of the high voltage semiconductor pulse

generator unit (SPGU). 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
