  • WARNING
    • MATCHING AMPLIFIER OUTPUT COAXIAL CABLE SHIELD IS NOTGROUNDED. FOR SAFETY, OUTPUT COAXIAL CABLE SHIELD SHOULD BE GROUNDED AT COAXIAL CABLE TERMINATING RESISTOR.
    • If output coaxial cable is connected to matching amplifier input ground or matching amplifier 115 volt ground, there may be excessive ground currents causing electrical noise in matching amplifier output.
  • CAUTION
    • Do not subject output to reverse voltage.
    • External pickup from coaxial cables can easily exceed safe values if the cables are run near high pulse current conductors.
    • The matching amplifier, coaxial cable and coaxial cable terminating resistor are calibrated as a system.
    • If any of these are changed, the calibration, the high frequency response and the pulse response may change.
