Models 4007B and 4013B are versatile DDS
(direct digital synthesis) sweep function
generators with high signal precision and stability.
These instruments generate sine and square
waveforms up to 7 MHz or 12 MHz, including
triangle waveforms up to 1 MHz. Both models
provide variable output voltages from 0 to 10 Vpp
into 50 ohms or up to 20 Vpp into open circuit.
A continuously variable DC offset allows the
output to be injected directly into circuits at the
correct bias level.
Features & Benefits
