Figure 5-8: Current limit
CC mode
The current I
max
corresponds to the current setting adjustable in the instrument.
If I
out
reaches I
max
, the instrument switches to CC mode, i.e. the output current remains
constant and limited to I
max
even if the load increases. Instead, the output voltage V
out
decreases to almost zero with a short circuit. In CC mode, the font text in the channel
display area changes to red.
See Figure 5-3.
5.4 Basic Functions
5.4.1 Setting the Channels Voltage and Current
NGE103B comes with three channels and NGE102B comes with two channels.
Toggle the respective channel key (Ch 1, Ch 2 or Ch 3) on the front panel to select
these channels. When a channel is selected, the respective channel key illuminates.
See Figure 5-9.

Set output voltage and current
The R&S NGE100B adjust voltage values between 0 V to 32.2 V with a step size of
0.01 V and current values between 0.003 A to 3.025 A with a step size of 0.001 A.
