The 3245A Universal Source combines the features of a precision dc voltage source, dc current source, synthesized function generator, and an arbitrary waveform generator. The 3245A can produce DC voltage and current with 24-bit resolution in high-resolution mode. The 3245A produces standard waveforms of sine, square, triangle, and ramp with variable duty cycle up to 1 MHz in addition to arbitrary waveforms. Frequency resolution is 0.001 Hz with 50 ppm frequency accuracy. Option 001 adds a second output channel. Option 002 adds a high voltage amplifier that increase output levels by a factor of ten.
