Digital I/O connector
The Digital I/O connector is a terminal block for external trigger input or output.
Measurement control can be achieved by means of an external input signal or using an
external output signal to trigger other instruments for some measurements.
The Digital Trigger I/O option (NGE-K103) must be installed for this function to be
available in the instrument.

4.2.2 Switching On the Instrument

Prior to switching on the instrument, check if the value on the voltage selector corre-
sponds to the mains voltage (115 V or 230 V). Switch it, if necessary, and change the
power fuse of the instrument accordingly.
To change the power fuse:
1. Peel off the yellow label sticker on the AC inlet.
2. Pull out the fuse holder which is located directly on top of the socket.
3. Remove the preloaded fuses from the fuse holder.
4. Check the caps of both fuses that you want to change to for their ratings. There
should be written either T5A250V for 115 V or T2.5A250V for 230 V. The fuse size
is 5 x 20 mm.
5. Once verified, insert the fuses into each groove of the fuse holder.
6. Return the fuse holder to its position in the panel.
To switch on the instrument:
1. Connect the power cable to the AC inlet and switch on the mains power.
2. Press Power key on the front panel.
The instrument performs a system check, boots the operating system, and starts
the R&S NGE100B firmware.
By default, all output channels are off when the instrument is switched on to pre-
vent connected loads from being damaged unintentionally.
Instrument settings from memory location M1 and auto saved parameters are loa-
ded during the instrument startup.
For more information on the store/recall instrument settings, see the "Store and
Recall" chapter in the user manual.
To switch off the instrument, press Power key again.
