The Varian CPI VPW6700P1A is a portable klystron test set engineered to evaluate high-power klystron tube operability through cathode emission measurement at a nominal beam voltage of 1000 VDC. The instrument delivers manual control over heater and beam voltage supplies, enabling technicians to condition tubes in storage, age devices prior to deployment, or remediate contamination. Real-time monitoring of heater voltage/current and beam voltage/current supports accurate performance assessment across GEN III, CKPA, and GEN IV klystron families.
