INTRODUCTION
Introducing WavePulser
WavePulser 40iX is the ideal single measurement tool for high-speed
hardware designers and test engineers. The combination of S-parameters
(frequency domain) and Impedance Profiles (time domain) in a single
acquisition, with a deep toolbox for simulation, emulation, de-embedding
and time-gating, provides unmatched characterization insight.
Designed for High Speed Interconnect Analysis
WavePulser is designed specifically for high-speed interconnect analysis.
It validates, debugs and troubleshoots interconnectivity issues in serial
data cables, channels, connectors, vias, backplanes, printed-circuit
boards, chip and SoC packages. It is simple to set up and use.
Internal, Automatic Calibration
WavePulser calibration standards are built-in (included in the standard
unit) and calibration is always automated, simple and fast—make one
connection to the DUT and press Go. WavePulser does not require
the purchase of additional, external calibration standards. In fact,
WavePulser's TDR/TDT-based approach is independent of setup, making
calibration less likely.
Full-range DC to 40 GHz
WavePulser provides results to DC and extending to 40 GHz of bandwidth,
so TDR step response and time-gated and/or emulated physical layer
signal responses can avoid extrapolations for low-frequency and DC
response—ideal for interconnect systems.

WavePulser Getting Started Guide 3
WavePulser Approach
WavePulser uses time domain reflectometry to characterize a DUT’s elec-
trical behavior by stimulating the DUT with impulses and measuring reflec-
tion and transmission. Once a measurement is configured, all phases
proceed without any user intervention whatsoever. This is accomplished
using an internal switch matrix assembly that routes pulses to internally
connected standards and to the front panel ports. After acquiring calibrat-
ed measurements of the DUT, post-processing calculations are performed
such as de-embedding, time-gating, etc. The post-processing calculations
can even be reconfigured and new results calculated without the need for
new measurement acquisitions.
SOLT Calibration Phase
In the calibration phase, pulses are routed to internal short, open, load,
and thru standards while measurements are made of these standards.
The measurements are processed along with measurements made at the
factory to provide an internal self-calibration at the instrument ports.
TDR/TDT Measurement Phase
In the DUT measurement phase, pulses are routed out to the DUT through
the front panel bulkhead connector and cables. Multiple acquisitions are
taken with the DUT pulsed at each port.
S-parameter Calculation Phase
On the host PC, the WavePulser application uses algorithms to apply the
calibration to the DUT measurements and to de-embed the instrument
cables to provide calibrated DUT measurements at the DUT ports. In this
phase, any further processing is performed, such as fixture and adapter
de-embedding, time-gating and physicality enforcements.

Power and Ground
Use only the Power button to power down. Do not power down by
switching off a connected battery/power strip or pulling the AC line cord
from the outlet while the instrument is turned on.
CAUTION. In "Standby Power" mode the instrument is still
connected to the AC supply. The only way to fully power down the
instrument is to physically disconnect the power cord from the AC
outlet. We recommend unplugging the instrument if it will remain
unused for a long period of time
Use only the power cord shipped with the instrument and certified for
the country of use.
The instrument is provided with a 10A/250V 18AWG rated grounded cord
set containing a molded three-terminal polarized plug and a specific
IEC-60320 (Type C13) connector for making line voltage and safety
ground connections.
Maintain ground. The AC inlet ground is connected to the frame of the
instrument. For adequate protection against shock, connect line cords
only to outlets with safety ground contacts.
WARNING. Interrupting the protective conductor inside or outside
the WavePulser, or disconnecting the safety ground terminal,
creates a hazardous situation. Intentional interruption is prohibited.
Operating Environment
Use indoors only.
Use only within the operational environment listed. Do not use in wet or
explosive environments.
Temperature 5 °C to 40 °C
Humidity Maximum RH 80% (non-condensing) up to 30 °C
decreasing linearly to RH 50% at 40 °C
Altitude Up to 10,000 ft (3,048 m) at or below 30 °C
Safety
To maintain the instrument in a correct and safe condition, observe gener-
ally accepted safety practices in addition to the precautions specified here.
CAUTION of potential damage
to equipment, or WARNING of
potential bodily injury. Refer to
manual. Do not proceed until the
information is fully understood
and conditions are met.
WARNING. Risk of electric shock
or burn.
Electrostatic Discharge Warning.

ESD Precautions
CAUTION. The WavePulser is sensitive to damage by Electrostatic
Discharge. Always wear the supplied grounding wrist strap and
take standard ESD precautions when using the WavePulser.
Connect the strap to the ground terminal on the front of the WavePulser.
CAUTION. Cables are capacitors. Always park the relays (p.11) and
discharge the center conductor of the WavePulser cables to
ground before connecting them to the WavePulser unit or the DUT.
Failure to do so may result in electrical damage to the pulser/
samplers that is not warrantable. Do not connect or disconnect
cables during measurements or TDR/TDT acquisitions when the
relays are engaged.
General Precautions
Connect and disconnect cables properly. Turn only the nut on the cable
connector to tighten/loosen cables, do not rotate the pins.
Do not remove the covers or inside parts. Refer all maintenance to
qualified service personnel.
Use only as intended by manufacturer.
Do not operate with suspected failures. Check the unit and cables
regularly. If any part is damaged, or you suspect the protections haved
been impaired, cease operation immediately and secure the instrument
from inadvertent use.
Cleaning
Keep product surfaces clean and dry. Follow instructions on p.32.
Cooling
The instrument relies on forced air cooling with an internal fan and
ventilation openings. An internal fan control circuit regulates the fan speed
based on the ambient temperature. This is performed automatically after
start-up with no manual intervention required.
Care must be taken to avoid restricting the airflow around the openings at
the side and rear of the instrument.
Do not block the cooling vents. Leave a minimum four-inch gap
(10 cm) between the instrument and the nearest object. Do not
allow foreign matter to enter through the vents.
Calibration
The recommended factory calibration interval is one year. Calibration
should be performed by qualified personnel only. See p.33 for instructions
on returning the instrument to Teledyne LeCroy Service.

The WavePulser ships with high-phase stability cables that are calibrated
and serialized to the WavePulser unit, along with the S-parameter les for
de-embedding each cable.
Cables
The cables utilize 2.92 mm K connectors.
The connector head on the end of the cable to be connected to the
WavePulser has a colored band matching the color of the port to which it
is calibrated. Always be sure to connect the cable to the matching port so
that the proper S-parameter le is used to de-embed the cable. See p.10.
We recommend leaving the cables attached once connected to the
WavePulser; there is no need to remove them when not in use.
CAUTION. Cap exposed cable connectors with the supplied end
caps to keep them clean when not in use.
