Nuclear pulse generator

[lojius]

i'm using Multisim  v.10, want to do a simulation for readout electronic for nuclear detector.

First, i need a function generator (refer attachment)  as input pulse for my readout electronic. The pulse is like a Negative Ramp, start at 0V & the amplitude is adjustable up to 1V

Thanks.

The easiest way to do this is with a piecewise liner source (SOURCES > SIGNAL_VOLAGE_SOURCE > PIECEWISE_LINEAR_VOLTAGE). You can construct the sawtooth behaviour by entering data points, and repeating the signal. See the image below for how you should configure the source.
