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/ramp 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.
These models are suitable for education and
other applications that need basic DDS function
generators with sweep capability.
