Fast Frequency Switching
The fast frequency switching of the Giga-tronics 2400 Series Microwave
Synthesizer pays dividends in any test environment where large amounts of
data are collected. Regardless of the complexity of your application, such as
antenna characterization or RFIC testing, the 2400 Series will quickly prove
itself as your best test investment by providing quick settling of amplitude
and frequency for minimum waiting between measurement points. In addition,
the 2400 Series Automation Xpress software and interface option ensures
unmatched 2.5 ms CW frequency and power switching performance, providing
fast and exible data exchange rates for faster testing and more device
throughput.
Low Phase Noise
The Giga-tronics 2400 Series Microwave Synthesizers deliver state of the
art phase noise and fast switching simultaneously. The 2400 Series low
noise, high power and excellent phase stability are ideal for serving as your
measurement system’s local oscillator and makes it suitable to serve as a low
jitter clock.
Faster to Program
Every 2400 Series Microwave Synthesizer comes with Giga-tronics WaveMaker,
a PC based software package designed for enhanced user interface and
automatic test systems. WaveMaker leverages industry-leading software
applications and familiar Windows drop-down menus and other functions to
perform tasks. Using any Windows-based application, such as Microsoft™ Excel
or Notepad, engineers can create, manage and download complex lists in a
matter of seconds-right from the comfort of their desktop PC.
Simpler to Operate
From the rst glance, it’s clear the Giga-tronics 2400 Series is different. Its
innovative design and intuitive interface will make you productive right out
of the box. The 2400 was designed to streamline user navigation by moving
complex testing functions from the front panel to the desktop PC. The result
is a groundbreaking system that reduces training time, speeds workow and
dramatically boosts end-user productivity. To enhance user navigation, we
minimized the number of soft screens and menu layers, simplifying content
and improving operational performance. That means you’ll spend less time
scrolling through data menus and more time getting your work done.
2400A Series Optimized for ATE
With the 2400A Series, ATE integrators now have a system source specically
designed to match their unique performance needs. The 2400A Series
works seamlessly with other instruments. It includes hardware triggering
and synchronization signals with programmable delay to allow coordination
with other test products in your system. Emulating other industry-standard
microwave synthesizers can be accommodated, making the 2400A Series the
ideal choice for upgrading older systems. The 2400A Series standard features
include a 3U rack mountable microwave synthesizer with rack ears, a high
stability timebase option, rear RF-output, GPIB-interface, and a blank front
panel-all for one competitive price.
