Figure 5-7: Output performance graph

According to the basic electrical formula for power (P) = current (I) x voltage (V), the
following results for the maximum power per channel:

●

NGA101, NGA141: 40.0 W for single channel

●

NGA102, NGA142: 40.0 W per channel (80 W max for the combination of two
channels)

For more information on the combination of channels, see

Chapter 8.1, "Parallel and

Series Mode"

on page 110.

Operation Modes

The R&S NGA100 operates in two different modes, i.e. CV and CC. The instrument
switches automatically between CV and CC depending on the connected load.

CV mode

Figure 5-8

shows that if the instrument is in the range of voltage regulation, the output

voltage V

out

remains constant while the current may increase to its maximum value I

max

when the connected load is increasing. In CV mode, the font text in the channel display
area changes to green.
