4080 Series
Programmable DDS Function Generators
Signal Generators
The 4084AWG and 4086AWG are
laboratory-grade DDS function generators
with basic arbitrary waveform capability.
They produce sine waves up to 20 MHz
(4084AWG) or 80 MHz (4086AWG) and can
also generate 26 other built-in waveforms.
The arbitrary waveform generator can
provide eight waveforms with up to 16,000
points each with 10-bit vertical resolution.
AM/FM/FSK/PSK modulation types are
provided, along with linear/log sweep, burst
(up to 10,000 cycles), and gate capabilities.
Ten instrument setup states can be stored in
non-volatile memory. Setup parameters can
be entered with a keypad or a knob. A serial
port provides programmability with
SCPI-compatible syntax.
Arbitrary Waveform Generation Software
(4084AWG & 4086AWG)
B&K Precision's 4080 series consists of
laboratory-quality DDS function generators
featuring 1 µHz to 120 MHz output and
amplitudes of 1 mVpp to 10 Vpp into 50 Ω
(reduced output above 40 MHz). Besides
providing sine, square, triangle, ramp, and
pulse waveforms, there are 19 other built-in
specialized waveforms.
