    It is assumed that only qualified and trained personnel service the power supplies and the connected loads. Use only the R&S NGA100 power supply series when operating the channels in a ser- ies or parallel mode to increase the output voltage and current.

  • Page 114: Parallel Mode

    ® Applications R&S NGA100 Parallel and Series Mode Figure 8-1: Example of series connection 8.1.2 Parallel Mode If it is necessary to increase the total current, the power supply outputs must be wired in parallel. The maximum total current is the sum of the individual currents of all sour- ces connected in parallel.
  • Page 115 ® Applications R&S NGA100 Parallel and Series Mode Figure 8-2: Example of parallel connection Principles of operation in parallel mode Generally, a higher current will first be supplied from the channel with the higher output voltage. Once this channel reaches its power limit, the remaining current will be made available by the channel that is connected in parallel.

    ® Additional Basics on Remote Control R&S NGA100 Messages and Command Structure are device-specific, however, their syntax follows SCPI rules as permitted by the standard. Instrument responses Instrument responses (response messages and service requests) are messages which the instrument sends to the controller after a query. They can contain measurement results, instrument settings and information on the instrument status.
