Satellite Payload Test Instrument

The STI 1000 is a synthetic microwave test system optimized for test-

ing satellite payloads in a factory setting. The STI 1000 can be used

either as a stand-alone instrument or controlled by an external net-

work as part of enterprise-wide factory automation. The STI 1000 is

designed to dramatically improve integrated payload test times and

reduce measurement errors introduced by either the operator or the

test hardware. Through its digitally synthesized stimulus and

response system design, the STI 1000 can easily be configured both in

hardware and software to meet specific user requirements.

HARDWARE

The STI 1000 hardware architecture is based on advanced synthetic

instrument concepts. Through the use of this flexible design, the STI

1000 replaces and replicates several microwave test instruments

including: a microwave power meter, a frequency counter, multiple

sources, a spectrum analyzer, a vector network analyzer, a noise figure

meter and an intermodulation analyzer. All of these instruments are

represented by the STI 1000. A basic STI 1000 includes several stim-

ulus generators and a fast

channel. Options can

include the addition of

arbitrary waveform gener-

ators for complex analog

or digital modulation

waveforms, telemetry and

control paths and multi-

ple response channels. An
