25 MHz Arbitrary / Function Generators
Models 4075 & 4078
Generate waveforms with ease
The included PC Software allows you to easily
generate, edit and download custom arbitrary
waveforms.
Generate waveforms by importing a textfile, or
define via freehand, point draw or waveform
math. Waveforms can also be uploaded from the
generator for documentation purposes.
Versatile noise generation
In Arb mode you can conveniently add noise to
your waveform directly from the front panel and
precisely adjust the scale of the noise amplitude.
Unlike other generators that only produce a
noise waveform, this feature allows you to
choose between generating a noise waveform or
adding noise to an existing waveform.
Programmable Markers
Models 4075 and 4078 provide fully program-
mable markers, allowing you to generate a
positive TTL level output signal at the points
specified by address and length up to 4000
points. This feature is available in Arbitrary mode
and can not be found in other comparable
waveform generators. It could be used for
applications requiring polyphase signal
generation, e.g. simulation of a real world 3
phase AC network where one of the phases is
degraded with spikes or noise.
Flexible memory management
Unlike other comparable generators, which
typically contain only a few fixed-size memory
locations for waveform storage, the 4075 and
4078 gives users more freedom - the 400000
point flash memory can be allocated to one large
waveform or up to 50 different waveforms, each
with a customizable length.
