  • Page 169 Many of the test procedures require the use of a variable load capable of dissipating the required power. For all tests, a Keysight MP4300 mainframe, with MP4361A modules can be used as a load. The electronic load unit is considerably easier to use than load resistors.

  • Page 170: Performance Verification

    The performance verification tests are recommended as acceptance tests when you first receive the instrument. The acceptance test results should be compared against the instrument specifications. Keysight Technologies recommends that you repeat the performance verification tests at every calibration interval. This ensures that the instrument will remain within specifications for the next calibration interval and provides the best long-term stability.
