CComparing N3300A Series Electronic Loads withEarlier ModelsIntroductionThe Keysight N3300A Series Electronic Loads covered by this manual are compatible in many ways withthe previous HP/Keysight 6050B, 6051B, 60501B, 60502B, 60503B, 60504B, 60507B Electronic Loads.This means that in most cases, programs written for earlier electronic loads will run on the N3300A SeriesElectronic Loads. However, be aware that there are also many differences between the previous versionand the N3300A Series loads that will require you to modify previous electronic load programs.If you are using Keysight N3300A Series Electronic Loads in test systems or with software designed for6050B, 6051B, 60501B, 60502B, 60503B, 60504B, 60507B Electronic Loads, you may experience someof the differences documented in Table C-1. If so, refer to the possible reason for the difference in TableC-2 for suggestions on what to do about the difference.It is not the intent of Table C-2 to provide an exhaustive list of all the differences between previousversion electronic loadss and the N3300A Series loads or all possible solutions to problems withpreviously written software. This table only highlights the areas that affect the behavior of the instrumentin normal use.NOTE: For additional information, please contact your Keysight Sales and Support Office listedat the back of the User's Guide.Table C-1.
