Agilent HP E1440A VXI21 MHz Synthesized Function/Sweep Generator
The Agilent 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 E1440A modules can be used for generating multi-phase related
signals.
With this module, you can use the modulation source as an arbitrary
function generator via GPIB 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.
Features:
- Five different waveforms
- Multi-interval sweep and multimarker mode
- Amplitude and phase modulation
- 1 µHz - 60 MHz TTL clock
- High-voltage output option, Isolated (floating) outputs
- Two or more HP E1440A modules for generating phase-related signals
