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 response measurement 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 innovative calibration design allows for the cali- bration plane to be extended beyond the For the very latest specifications visit www.aeroflex.com SSTTII11000000 iiss aa ssyynntthheettiicc mmiiccrroowwaavvee tteesstt ssyysstteemm ccoonnffiigguurreedd ffoorr tteessttiinngg ssaatteelllliittee ppaayyllooaaddss iinn ffaaccttoorryy eennvviirroonnmmeennttss..

instrument to the satellite connection point, even in a vacuum. The calibration design also allows for the system to be fully calibrated without disconnecting from the satellite. This calibration only takes seconds to perform and can be used to minimize system errors due to temperature variations. Hardware paths are designed to support both high-speed, real-time calibration along with System Functional T est. Functional T est mon- itors the performance of the System and the remote calibration unit for proper performance. This minimizes false “fails” and provides a high level of confidence in the performance of the STI 1000 and qual- ity of the data produced. FIRMWARE The STI 1000 offers “programmable firmware” to allow for user opti- mization of the test instrument. Using the latest design concepts, the STI 1000 makes it easy to add tests and modify test algorithms. Additionally, simple structures such as data formats, test reports, user interfaces and graphical output may be customized. A standard instrument interface via TCP/IP (Ethernet) allows for control by any external computer platform and commercial test control software. A VXI Plug-n-Play driver is provided for integration into the user’s test control software. A multi-layered architecture insures that the data acquisition and processing is performed as fast as possible. TEST INTEGRATION One of the keys to the STI 1000’s speed advantage is through “T est Integration”. This is the ability of the STI 1000 to collect a single data set that provides results for multiple test requirements. For example, the STI 1000 can extract results for in-band, out-of-band, group delay and amplifier transfer characteristics from a single data set. Using T est Integration along with the acquisition speed advantage of the STI 1000 greatly increases the data throughput of the instrument. MEASUREMENT SCRIPTING The basic concept is that the STI1000 provides a functional meas- urement capability that is independent of traditional rack-and-stack- instrument functionality. The method for defining a measurement personality is through a downloaded script file. Any number of scripts may be loaded at any time and sequenced via a test executive or other external test controller. Thus, through a simple command, the STI 1000 may change from one measurement (i.e. vector network analyz- er) to another (gain transfer tester). The STI 1000 is measurement driven not instrument driven. Currently, Aeroflex can provide the following measurement personal- ities while others can easily be added: Gain T ransfer In Band Frequency Response Passive Intermodulation Out of Band Frequency Response Group Delay System Level Phase Noise Noise Figure T elemetry Output Power Absolute Propagation Time T elemetry Frequency T elemetry Modulation Index AM/PM Conversion Command Sensitivity Lock/Unlock Threshold Command Receiver AGC Calibration EIRP and SFD Analyzer Sweep Gain Control Noise Power Ratio Amplitude Linearity Frequency Conversion Phase Non-Linearity Spurious Outputs Beacon T ransmitter Output Power/EIRP Insertion Loss Calibration Beacon T ransmitter Frequency Ranging Automated Command Function T&C Omni Antenna Manual Patterns Gain Monitoring TTYYPPIICCAALL SSYYSSTTEEMM LLEEVVEELL SSPPEECCIIFFIICCAATTIIOONNSS (Satellite Test Configuration) Frequency Coverage 0.200 – 32 GHz (Up to 110 GHz optional) Coherent 1 or 2 Hz Resolution Number of Ports
