Description

The HP E1440A function/sweep generator is a C-size,
2-slot, message-based VXI module. It provides low-

distortion sinewaves and a variety of waveforms for
applications requiring high frequency stability and
resolution (11 digits). A programmable relative phase
output synchronized to a companion module is also
available. Two or more HP E1440A modules can be
used for generating multi-phase related signals.

HP E1440A

With this module, you can use the modulation source as
an arbitrary function generator via HP-IB to provide
user-defined waveforms, or use the save-recall memory
that includes nonvolative memory locations for simple
and rapid access to frequently used test setups.
Additionally, you can produce five different waveforms
including: sine, square, triangle, negative, and positive
ramps.

Refer to the HP Website for instrument driver
availability and downloading instructions, as well as for
recent product updates, if applicable.
