incorporated in the power cord). The mains plug shall only be inserted in a
socket outlet provided with a protected earth contact. Any interruption of the
protective conductor inside or outside of the product is likely to make the
product dangerous. Intentional interruption is prohibited.
CAUTION This product is designed for use in Installation Category II and Pollution Degree 2
per IEC 61010 Second Edition and 664 respectively.
WARNING If this product is not used as specified, the protection provided by the
equipment could be impaired. This product must be used in a normal condition
(in which all means for protection are intact) only.
WARNING No operator serviceable parts inside. Refer servicing to qualified personnel. to
prevent electrical shock do not remove covers.
CAUTION The Mains wiring and connectors shall be compatible with the connector used in the
premise electrical system. Failure to ensure adequate earth grounding by not using
the correct components may cause product damage, and serious injury.
Safety Symbols
The following symbols on the instrument and in the manual indicate precautions
which must be taken to maintain safe operation of the instrument.

1 Introducing the N8241/2A AWGs
The N8241A and N8242A are wideband arbitrary waveform generators (AWGs)
capable of creating high-resolution waveforms for radar, satellite and frequency
agile communication systems. Each channel of the AWGs operates at 1.25 GSa/s.
The N8241A features 15 bits of vertical resolution and the N8242A 10 bits. Both
AWGs offer dual differential output channels to drive both single-ended and
balanced designs.
The AWGs include a complete software suite to speed waveform development and
system integration supporting MATLAB®, LABVIEW, and IVI-C programmatic
interfaces.

5 CH 1/CH2 Out The CH 1 OUT and CH 2 OUT positive (+) connectors are
used for single-ended operation. Use both the positive (+)
and negative (-) connectors for differential operation. Refer
to “Signal Conditioning” on page 84 for more information.
6 AUX PORT The AUX port is reserved for future applications.
7DATAPORT The data port is reserved for future applications.
8TRIGGERS 1/2/3/4 There are four SMB female trigger input connectors that are
used to control the waveforms in the sequencer and create
event-based signal simulation. The connectors support
TTL/CMOS, ECL, and PECL logic levels.
9 MARKERS 1/2/3/4 There are four SMB female marker output connectors that
can be used for triggering or system synchronization. The
connectors are 3.3V TTL/CMOS 30 ohm series terminated.
The output is capable of driving a 50 ohm load.
10 Power Switch The power switch is toggled to either the ON or STANDBY
position.

11 Reset The “RST” button enables you to put the LAN configuration
of the instrument into a known state.
When you press this button the following settings are made
and the system reboots:
• IP Address is set to 192.168.EE.FF, where EE and FF are
the last two parts of the MAC address
(AA.BB.CC.DD.EE.FF). This is designed to prevent
multiple instruments from using the same default IP
address.
• Subnet Mask is set to 255.255.0.0
• DHCP is set to ON
• Auto IP is set to ON
• The instrument hostname is set to A-N82XXA-NNNNN,
where N82XXA is the instrument model number (such as
N8241A) and NNNNN represents the last five digits of
the instrument serial number.
12 TRIGGER IN/OUT These SMB trigger input and output connectors are used to
control the waveforms and create event-based signal
simulation. The connectors support LVTTL logic levels and
are functionally equivalent to Triggers/Markers 1-4, but have
additional latency.
13 10 MHz REF IN/OUT These SMB connectors can be used to input and output a
10 MHz reference.

1LXITRIGBUS This interface enables the instrument to detect any LXI
trigger bus events or LXI LAN-based events and can output
such events.
Inbound events control the arming and triggering of the
instrument subsystem for performing measurements and
other operations. Outbound events are used to notify other
LXI devices of specific conditions.
An LXI TRIG BUS cable and terminators will be available
from Circuit Assembly in the near future.
2 AUX INTF This 9-pin serial interface connector is for factory-use only.
3 AC Power Receptacle The AC voltage is connected here. The power cord receptacle
accepts a three-prong power cable that is shipped with the
instrument. The voltage range is 100/120/220/240 volts with
a frequency range of 50 to 60 Hz and is automatically
selected by the power supply.
