Model Description:
Universal Horizontal Analyzer

Model Details

The HA2500 Universal Horizontal Analyzer is the one instrument designed specifically for analyzing all horizontal and B+ related defects. The HA2500 teams up with the VG91 Universal Video Generator or any of the Sencore computer monitor generators (or use it stand-alone) to give you complete monitor analyzing. Its patented and exclusive features gives the HA2500 the capabilities to help you service computer monitors faster and more profitably than ever before. The HA2500 provides exclusive analyzing test and substitution capabilities to localize horizontal circuit defects faster than using conventional methods. The "chassis off" test determines if the horizontal stage is free of severe defects or if problems exist. The patented "ringer" test dynamically tests coils and transformers for one or more shorted turns - a common failure of flybacks. The exclusive Dynamic Tests analyze the input and output voltage parameters of the horizontal output stage with the chassis powered on.


  • Unique frequency lock and variable horizontal frequency use allows you to quickly service all horizontal circuits no matter the frequency
  • Patented "ringer" proves the condition of flybacks and yokes in seconds - even a single shorted turn
  • Variable-current limited & protected B+ substitute power supply permits testing of horizontal stages even when the power supply is dead
  • Exclusive "Horizontal Output Load Test" makes setup and testing a snap - even without applying AC power for more accurate estimates, fewer damaged replacement parts, and faster diagnosis and repair
  • Exclusive "Dynamic Tests" help you analyze the horizontal circuit in powered-up conditions to catch even subtle defects in the power supply, noise, and drive signal
  • Portable and field rugged to go on location when bringing the defective product to your bench isn't feasible
