[SOURce:]CURRent:RANGe 7.4 Remote sense function The "Remote Sense" is a mechanism used to monitor and compensate the voltage drops on the cables connected to the load. Once the remote sense is activated, it becomes part of the output feedback path for R&S NGA100.
Page 58 ® Instrument functions R&S NGA100 Channel fusion "EXT" The internal voltage sense relay in the instrument is switched on and the connection of remote sense wires (S+, S-) to the input of the load become necessary. Failure to connect remote sense can cause over- voltage or unregulated voltage output from the R&S NGA100.
Page 59 ® Instrument functions R&S NGA100 Channel fusion Connection Mode ← ChannelFusion Sets channel fusion connection mode. "Off" Channel operates separately. "Series" In series mode, the two terminals in the middle are used for output. There is an internal series link activated to connect channel 1 and channel 2 output.
Page 60 ® Instrument functions R&S NGA100 Electronic fuse 7.6 Electronic fuse To protect a connected, sensitive output in general, the R&S NGA100 power supply includes an electronic fuse which can be switched on individually for each channel. A fuse delay can be applied to each channel and individual electronic fuses can be log- ically linked to switch off the interlinked channels if a fuse triggers.
Page 61 ® Instrument functions R&S NGA100 Electronic fuse 7.6.2 Fuse delay, fuse linking The fuse delay and fuse linking functions provide the flexibility to handle a fuse tripped event when it occurs. When the current for a channel exceeds the value I and the fuse tripped event triggered, the affected channels are turned off according to the set- tings configured in the fuse delay and fuse linking.

Page 148 ® Applications R&S NGA100 Parallel and series mode 12 Applications 12.1 Parallel and series mode To increase output voltage and currents, it is possible to operate the channels in series or parallel mode. In general, the output voltages of R&S NGA100 to be combined are independent.
Page 149 ® Applications R&S NGA100 Parallel and series mode Figure 12-1: Example of series connection 12.1.2 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 150 ® Applications R&S NGA100 Parallel and series mode Figure 12-2: Example of parallel connection Principles of operation in parallel mode Generally, a higher current is first supplied from the channel with the higher output volt- age. Once this channel reaches its power limit, the remaining current is made available by the channel that is connected in parallel.
