Characteristic Impedance (Zo)
The impedance of all cable is measured using one of three Tektronix 1502 Time Domain Reflectometers(TDR), calibrated with a General Radio 900-LZ10 50 ohm airline. Measurement resolution is 0.1 ohms. The TDR is also used for bulk continuity checks and as a fault locator for cable and assemblies. Impedance measurements are also obtained using a Tektronix 11802 Digital Sampling Oscilloscope with SD-24 TDR Plug-In.

Return Loss (VSWR) and Insertion Loss (Attenuation)
A pair of Hewlett-Packard 8510 Network Analyzers are used for these measurements. H-P plotters are available for for graphical hardcopy output. Calibration standards allow 50 ohm and 75 ohm test configuration.

Time Delay and Phase Matching
The 8510 Network Analyzers are also used for these measurements. HP plotters are available for graphical hardcopy output. Calibration standards are obtainable from 400 MHz to 20 GHz.

Cable capacitance is measured using a Doric 130A capacitance meter. Measurement resolution is 0.1 picofarads.

Dielectric Withstanding Voltage (Breakdown)
A Hipotronics HD 100 HiPot Tester is used to measure the high voltage capabilities of the cable. Measurements can be made to 6 Kilovolts, AC or DC.

Insulation Resistance
The dielectric resistance is measured using a Hipotronics HM3A megohmeter. Measuring capabilities extend to 100 megohms resistance, using measurement voltages to 1000 volts.

Corona Extinction Voltage
This cable parameter is checked with the Hipotronics 705-2CTS AC Corona Test Set. Corona Emissions as low as 1 pico coulomb can be detected.


  Thermal preconditioning is also available for cable and assemblies. Testing at elevated or reduced temperatures is also an option.  
  Assemblies can be as simple or as complex as required. Custom data collection is also an option available to all our customers.  
  Our fully equipped test laboratory is can produce data to 26 GHz. Parameters include VSWR, return loss, insertion loss, phase matching and time delay.
