Safety & Environmental Information
Ventilation
Ventilation
VENTILATION REQUIREMENTS: When installing the instrument(s) into a
cabinet, consideration shall be given to the convection flow into and out of the
cabinet. Consideration shall also be given to the individual instruments to avoid
having the heated discharge of one instrument, now becoming the cooling
intake air for another instrument.
Do not place the transceiver against any surface in such a way as to block its
ventilation openings. Interfering with ventilation airflow can cause the
transceiver to overheat.
Another area of concern is verification that the maximum ambient operating
temperature of the instrument(s) is not exceeded by cabinet installation.
Keysight recommends forced air convection whenever an instrument(s) are
installed in a cabinet and further recommends that the maximum operating
temperature of the cabinet be reduced 10°C from the lowest, of the maximum
operating temperature of a single instrument.
If there are any concerns or special requirements an Keysight Field Engineer
should be consulted to assure instrument(s) temperature compliance and
performance.

Safety & Environmental Information
Power requirements
Power requirements
The M1742A does not have an AC power connection. It is powered by a 19 Volt
DC input from an AC/DC converter. (In some test applications, the DC input is
furnished by a power supply, such as a Keysight N6702C, controlled remotely
by solution software.) This input does not represent a risk of personal injury.
Power requirements of the AC adapter
— Input: 100-240VAC, 50-60 Hz, 2.5 - 1 A
— Input power stability: the AC-DC adapter is certified and can operate with
mains supply voltage fluctuations up to ±10% of the nominal voltage.
— Output: 19 VDC, 6 A
The main power cord is the system disconnecting device. It disconnects the
mains circuits from the mains supply.
Using Accessories
Only Keysight-approved accessories shall be used.
Use the AC-DC power adapter and power cord which is supplied with the
product.
See the accessories listed under “Initial Inspection” on page 20.
Do not remove the DC input plug from the M1742A while it is in an active state.
Make sure the Status LED on the DUT-facing side of the M1742A is dark
before disconnecting the DC input.
This is a Safety Protection Class I Product (provided with a protective earthing
ground incorporated in the power cord). The mains plug shall only be inserted in
a socket outlet provided with a protective 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.
This instrument has auto-ranging line voltage input. Be sure the supply voltage
is within the specified range, and that voltage fluctuations do not to exceed 10
percent of the nominal supply voltage.

Weight and Dimensions
Weight and Dimensions
The weight and dimensions of the M1742A are as follows.
— Weight: 3.5 kg
— Height: 70 mm
— Width: 175 mm
— Length: 345 mm
Protecting against electrostatic discharge
Electrostatic discharge (ESD) can damage or destroy electronic components
(the possibility of unseen damage caused by ESD is present whenever
components are transported, stored, or used).
Test equipment and ESD
To help reduce ESD damage that can occur while using test equipment:
• Before connecting any coaxial cable to a test set connector for the first time
each day, momentarily short the center and outer conductors of the cable
together.
• Personnel should be grounded with a 1 M resistor-isolated wrist-strap
before touching the center pin of any connector and before removing any
assembly from the test set.
• Be sure that all instruments are properly earth-grounded to prevent
build-up of static charge.
• Perform work on all components or assemblies at a static-safe workstation.
• Keep static-generating materials at least one meter away from all
components.
• Store or transport components in static-shielding containers.
• Always handle printed circuit board assemblies by the edges. This reduces
the possibility of ESD damage to components and prevent contamination of
exposed plating.
Additional information about ESD
For more information about ESD and how to prevent ESD damage, contact the
Electrostatic Discharge Association (http://www.esda.org). The ESD standards
developed by this agency are sanctioned by the American National Standards
Institute (ANSI).
Do not use these first three techniques when working on circuitry with a voltage
potential greater than 500 volts.

Cleaning the Instrument
Connector Care
Threaded connectors can be damaged when cables are connected to them,
particularly if they are over-tightened (this could break the signal path entirely,
making the M1742A non-functional).
When connecting a cable to a port, thread the cable-end onto the connector
using your fingers, then use the torque wrench to tighten the connection.
Because connectors can become defective due to wear during normal use, all
connectors should be inspected and maintained to maximize their service life.
Inspect the mating surface each time a connection is made.
Metal particles from connector threads often find their way onto the mating
surface when a connection is made or disconnected. Clean dirt and
contamination from the connector mating surface and threads.
Disconnect the M1742A from all cables before cleaning. Use a dry cloth or one
slightly dampened with water to clean the external case parts. Do not attempt
to clean internally.
When attaching cables to threaded connectors, use a torque wrench to apply
the proper torque, as described in the table below.

Connector Cleaning
Cleaning connectors with isopropyl alcohol shall only be done with all cables
disconnected, and in a well-ventilated area. Allow all residual alcohol moisture
to evaporate, and the fumes to dissipate prior to energizing the instrument.
Keep isopropyl alcohol away from heat, sparks, and flame. Store in a tightly
closed container. The alcohol shall not be stored, or left open, in the area of the
equipment. Use isopropyl alcohol with adequate ventilation to prevent the
combustions of fumes or vapors.
Avoid contact with eyes, skin, and clothing, as isopropyl alcohol causes skin
irritation, may cause eye damage, and is harmful if swallowed or inhaled. It may
be harmful if absorbed through the skin. Wash thoroughly after handling. In case
of spill, soak up with sand or earth. Flush spill area with water. Dispose of
isopropyl alcohol in accordance with all applicable federal, state, and local
environmental regulations.
In case of fire, use alcohol foam, dry chemical, or carbon dioxide; water may be
ineffective.

Quick Start
Purpose and Function
Purpose and Function
The M1742A Transceiver is designed to be used as the RF interface between a
wireless test system and a Device Under Test. The M1742A upconverts the test
system’s Tx output to the higher range of the DUT, and downconverts the
received signal from the DUT to the lower range of the test system’s Rx input.
The DUT-facing ports of the M1742A (RF Tx/Rx 1 and RF Tx/Rx 2) are
half-duplex ports -- that is, either port can transmit or receive (although never
both at once).
Figure 2-1 M1742A used as an RF interface
On the left side of the M1742A in the diagram, the Tx IF In port takes an input
from the test system and upconverts it to the higher range of the DUT. Signals
received from the DUT are downconverted and returned to the test system
from the Rx IF Out port. In upconverting and downconverting, the M1742A
uses 3 reference inputs (from the test system): the 4.8/9.6 GHz In and the
Getting Started Guide 19
Quick Start
Purpose and Function
variable-frequency 2 x LO In. The LO input can include a modem control signal,
with embedded triggers; this eliminates the need for the USB controller and
trigger lines shown in the illustration.
The supplied AC/DC adapter provides a 19 VDC power input to the M1742A
(this can also be done by a DC power supply, if one is included in the system
setup).
The diagram below shows an example of the M1742A interfacing with a
specific test set (the M9410A VXT Test Platform).
