NEW! Watch our demo of this RF Transmitter/Receiver VSAT Test System.


Find out how this tool can help you with fast test times, increased throughput and configurable software and reports for custom applications.

BUC Testing Measurements
  • Output Power @ 1dB compression
  • Linear Gain vs. Frequency
  • Adjacent Channel Power Ratio @ +35 dBm based on 36 MHz wide TDMA modulation
  • LO Phase Noise
  • Receive Band Noise Density
  • Output Muting when 10 MHz reference is lost
  • DC Current

 

LNB Testing Measurements

  • Output Power @ 1 dB compression
  • Conversion Gain vs. Frequency
  • Noise Figure vs. Frequency
  • LO Phase Noise
  • DC Current

 

TestStand™ Automation

  • Versatile Test Configuration
  • Automated configuration of tests based on performance of prior tests
  • Summary Reporting of Multiple Test Cycles
  • Custom Report of Individual Test Cycles
  • Current Monitoring
  • Warm-up and Cool-down Cycles
  • Tests Integrated with Temp Chamber

 

The VSAT Transmitter and Receiver Test Station is a low cost COTS-based test station for testing transmitters and receivers used in a VSAT (Very Small Aperture Terminal) antenna. Automated test software enables full test automation. The VSAT test station is capable of full range testing of block up-converters (BUC) and low noise block down-converters (LNB). For customers needing additional functionality, G Systems also provides full customization services.

BENEFITS

  • Fast test times
  • Repeatable
  • Increased throughput
  • Optional database connectivity
  • Configurable software and reports for custom applications

 

Test Schematic

Custom software enables the test operator to select the device under test (DUT) part number and serial number and executes the test based on configured parameters for that part.  A configuration GUI enables entry and editing of DUT parameters.  At the end of each test, the software stores all results in a spreadsheet format and generates a printable report in PDF format.

 

Additionally, software screens instruct the user during the calibration measurement process.
