Setting the Channels Voltage and Current
The R&S NGA100 comes with the following instrument models:
Model
Voltage
Current
NGA101, NGA102
0 V to 35 V
<= 6 V: 6A
> 6 V to 9 V: 40 W
> 9 V to 20 V: 2 A
> 20 V to 35 V: 40 W
NGA141, NGA142
0 V to 100 V
<= 20 V: 2 A
> 20 V to 25 V: 40 W
> 25 V to 54 V: 0.75 A
> 54 V to 100 V: 40 W
Depending on models, toggle the respective channel key ([Ch 1] or [Ch 2] ) on the front
panel to select these channels. When a channel is selected, the respective channel
key illuminates. See

If "Arbitrary" function of a Ch 1 is enabled, the channel voltage or current setting is dis-
abled.

Depending on the instrument models, the R&S NGA100 adjusts the voltage and cur-
rent values with the following step size.
NGA101, NGA102
NGA141, NGA142
1 mV

1 mA
1 mA
The setting of current value corresponds to the I
max
of the respective channel. It is
advisable to set the current limit before operating the instrument to prevent damage to
the load and instrument in the case of malfunction like short-circuit.
