Introduction
Introduction
The S9115A supports mmWave testing, with up to two transmit/receive
modules (each driving an M1749B remote radio head to interface with
millimeter-wave devices under test. The second TRX unit is included only with
Option S9115A-TR2.
Each TRX unit in the S9115A system supports an IF output port, an IF input
port, and an LO input port powered by an external power supply and driven by
a USB control signal.

Protecting Against Electrostatic Discharge
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 an instrument 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 instrument.
— 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.

Unpack and Inspect the Instrument
Unpack and Inspect the Instrument
Before unpacking your instrument, inspect the packaging container for
evidence of mishandling during transit. Report any damage to the shipping
agent immediately, as such damage is not covered by the warranty (refer to the
warranty information at the beginning of this document).
Remove the instrument from the packaging container and ensure that all
accessories are included. Inspect the instrument and accessories for damage.
If the contents appear damaged, notify your local Keysight Technologies Inc.
representative.
The instrument is shipped in a container which prevents damage from
static. The instrument should only be removed from the packaging in an
anti-static area ensuring that correct anti-static precautions are taken.
Store the instrument in an anti-static envelope when not in use.
Visit www.keysight.com/find/tips for information on preventing damage to
your Keysight equipment.
Use care when lifting this instrument. Instrument is front heavy.
More than one person is required to safely lift or carry this
instrument. Alternately a mechanical lift can be used to eliminate
the risk of personal injury.

Initial Inspection
Inspect the shipping container and the cushioning material for signs of stress.
Retain undamaged shipping materials for future use, as you may wish to ship
the system to another location or to Keysight Technologies for service. Verify
the contents of the container against the table below.

Shipping Problems
If the shipping materials are damaged or the contents of the container are
incomplete:
— Contact the nearest Keysight Technologies office.
— Keep the shipping materials for the carrier’s inspection.
— If you must return the S9115A to Keysight Technologies, use the
undamaged original or comparable shipping materials. See “Returning the
S9115A for Service” on page 129.

Connect the Equipment
Connect the Equipment
Use the following procedure to attach cables between the S9115A base box to
the M1749B. For more information about the M1749B connectors and
connecting the M1749B, refer to the M1749B Getting Started Guide.
1. Following the connection description on the S9110-60013 cable bundle
ends, connect Transceiver 1 cable bundle between Transceiver 1
(M1749B) and the Transceiver 1 connectors on the S9115A base box.
If you have Option TR2, repeat this procedure for the second transceiver
cable bundle.
2. On the base box, connect LAN 10G to the Site LAN at your facility.
3. Connect a display, keyboard, and mouse (not included with the S9115A).
4. Connect the power cables from the AC/DC converters to the M1749Bs and
plug in the AC/DC power converters.
Refer to Chapter 1, “Safety and Environmental
Information before proceeding with the installation.
Threaded connectors can be damaged when connecting
cables, particularly if they are over-tightened. This could
break the signal path entirely, making the M1749B
non-functional.
When attaching cables to threaded connectors, use a torque
wrench to apply the proper torque, 90 N-cm (8 in-lb).

Launch the Measurement Software and Verify Operation
Launch the Measurement Software and Verify Operation
1. At bootup, the S9115A launches the S910xA Service Manager
automatically, and the Service Manager automatically launches the
measurement software. The initial start up process takes
approximately 5 minutes.
After the software is finished loading, the measurement applications
for TRX1 and TRX2 are run in separate windows (assuming two TRXs
are installed).
2. Let the system warm up for 1 hour prior to verifying operation.
3. To insure proper operation, you must run the following alignments:

User’s Guide 19
Quick Start
Launch the Measurement Software and Verify Operation
—Align Now All
— Align IF Cable
—Align RRH LO
—Align RRH Amplitude
a. Select the Gear icon at the top right to open the System
Settings window. Select the Alignments tab > Align Now >
Align Now All.
Align Now All will take about 25 minutes to complete. If an
alignment has failed, it will be displayed in the Status area
of the Control bar.
b. Select the Gear icon at the top right to open the System
Settings window. Select the Alignments tab > Align Now >
Align IF Cable.
c. Select the Gear icon at the top right to open the System
Settings window. Select the Alignments tab > Align Now >
Align RRH LO Power.
d. Select the Gear icon at the top right to open the System
Settings window. Select the Alignments tab > Align Now >
Align RRH Amplitude.
You must run Align Now All first, then Align IF Cable, then
Align RRH LO and Align RRH Amplitude.
TERMINATION IS CRITICAL!
This alignment requires that Keysight 85138A Coaxial
Terminations be connected to the M1749B Tx/Rx ports. If the
alignment is run without terminations in place, or with a
loopback cable connecting the two Tx/Rx ports, subsequent
measurements may be severely inaccurate.
