DDS Function Generators
The 4005DDS is a versatile 5 MHz function
generator using a DDS (direct digital
synthesis) design. This model is great for
education and other applications that need
basic waveform generation.
Features & Benefits
■ Sine, square, and triangle waveforms
up to 5 MHz
■ Number pad for quick input of
frequency
■ Adjustable DC offset
■ Adjustable duty cycle
■ Front panel push button and pull knob
can attenuate output by up to 40 dB
Additional Features
(4014B/4040B/4045B)
■ AM/FM modulation
■ Low-jitter square wave generation for
simulating reliable clock signals,
generating triggers, or validating serial
data buses
■ 12-bit, 50 MSa/s, 1k point arbitrary
waveform generator (4045B)
■ Internal/external triggering
■ Gate and burst mode (4040B and 4045B)
■ Built-in counter
■ USB interface and SCPI-compliant
command set
■ Remote control application software
provided
Model 4005DDS
The 4007B, 4013B, 4014B, 4040B, and
4045B DDS function generators are capable
of generating stable and precise waveforms.
All models provide variable output amplitudes
from 0 to 10 Vpp into 50 Ω and a continuously
variable DC offset to inject signals into circuits
at the correct bias level. Standard features
include an intuitive menu-driven front panel
keypad, rotary control knob, adjustable duty
cycle, and comprehensive short circuit and
overvoltage output protection. The 4045B
adds a 12-bit, 50 MSa/s, 1k point arbitrary
waveform capability with arbitrary waveform
editing software provided.
