pollution occurs. Occasionally a temporary conductivity caused by condensation must be
expected.
POWER REQUIREMENTS
The Digitizer operates from within a PXI chassis. Power requirements depend on the Digitizer
model as indicated in the PXD Series Digitizer Specifications section of this manual. DC voltages
are supplied to the instrument from the PXI backplane. The instrument requires a variety of DC
currents/voltages as outlined in the Specifications section.
CAUTION
Disconnect power to the PXI Chassis before installing or removing the
Digitizer.
COOLING REQUIREMENTS
The Digitizer relies on externally supplied forced air cooling for proper operation. A minimum airflow of 5 cfm (PXD212, 512,1021) or 15 cfm (PXD114, 214, 514, 522, 1022) to the Digitizer’s air
inlet at a temperature between 0 °C and 40 °C must be provided by the PXI chassis. The user
should ensure that the PXI chassis can satisfy these airflow requirements.
GROUNDING REQUIREMENTS
To conform to the applicable safety and EMC requirements, ensure that the Digitizer instrument
panel and the PXI chassis are "earth" grounded.
CAUTION
The outer shells of the front panel terminals (CH1, CH2, CH3, CH4, EXT) are
connected to the instrument’s chassis and, therefore, to the safety ground.

Operation
INTRODUCTION
This section provides information about the standard acquisition, triggering, and measurement
features of the PXD Series Digitizer. LeCroy PXD digitizers are IVI compliant which means that the
structure of commands for setting up, capturing, and reading out waveforms follows the structure
defined in Section 4 of the IVI Foundation specification (www.IVIfoundation.org). It is recommended that you review this section prior to programming the PXD modules. Detailed descriptions
of LeCroy commands are included in the Driver Help file.
ACQUISITION MODES
The Digitizer has three modes of operation: NORMAL, RIS (Random Interleaved Sampling), and
Sequence. These are defined as follows:
Normal
In Normal mode, the Digitizer will input the signals during a specified time window and create a
data array with the digitized data, which can be read out by the controller. The user programs the
number of points as well as the time window to be digitized on repetitive signals. LeCroy PXD Digitizers come with 256 kpoints of memory as standard. For storing longer single-shot signals, optimal memory of 4 Mpoints or 8 Mpoints/channel can be added. The maximum sample rate is 2 GS/
s, and will vary depending on the specific model and the time window setting.
RIS – For Higher Sample Rates
RIS (Random Interleaved Sampling) is an acquisition technique that allows effective sampling
rates higher than the maximum single-shot sampling rate. It is used on repetitive waveforms with a
stable trigger. The maximum effective Digitizer sampling rate of 50 GS/s can be achieved with RIS
by making 100 single-shot acquisitions at 500 MS/s. The bins thus acquired are positioned
approximately 20 ps apart. The process of acquiring these bins and satisfying the time constraint
is a random one. The relative time between ADC sampling instants and the event trigger provides
the necessary variation, measured by the timebase to 5 ps resolution.
The Digitizer requires multiple triggers to complete an acquisition. The number depends on the
sample rate: the higher the sample rate, the more triggers are required. It then interleaves these
segments to provide a waveform that is up to 50x faster than the single-shot sampling rate. However, the real-time interval over which the Digitizer collects the waveform data is much longer, and
depends on the trigger rate and the amount of interleaving required. The digitizer is capable of
acquiring approximately 40,000 RIS acquisitions per second.

Final capture
Sequence – Working With Segments
In sequence mode, the complete waveform consists of a number of fixed-size segments acquired
in single-shot mode. Select the number of segments to be captured, then select each segment
individually. Each trigger fills a new segment.
Sequence offers a number of unique capabilities. With it, dead time is limited between trigger
events for consecutive segments. The Digitizer can capture in fine detail complicated sequences
of events over large time intervals, while ignoring the uninteresting periods between the events.
Time measurements can be made between events on selected segments using the full precision
of the acquisition timebase.
Trigger time stamps of 1 ns resolution are given for each of the segments in the Text & Times Status menu. Each individual segment can be read out by the controller.
The Digitizer uses the sequence timebase setting to determine the capture duration of each segment: 10 x time/div. The digitizer uses this setting — with the desired number of segments, maximum segment length and total available memory — to determine the actual number of samples or
segments, and time or points.

TRIGGER MODES
In all acquisition modes, capturing the signal requires an edge trigger or a trigger generated from

PXD SERIES DIGITIZER QUICK START APPLICATION SOFTWARE
Operation
The Quick Start Application software provides an efficient way to view and verify PXD module performance. The simple control panel allows for amplitude adjustment, memory depth and triggering,
and a simple logging function. It is intended as a verification tool to ensure that the module installation has been completed.
901217-01 ISSUED: March 2003 29
PXD Series Digitizer
SOFT FRONT PANEL
The Digitizer Quick Start Application software has the following features for one to four channel
modules:
• Graphic display with independent vertical axis for each digitizer input channel
• Acquisition section including autosetup and reset
• Channels section with independent control of probe attenuation, Volts/Div, Offset,
Bandwidth limit, and coupling
• Timebase section including Time/Div, Delay, and acquisition type as well as indicators for
the number of points per acquisition and the sample rate
• Trigger section with source, coupling, slope, type, and level selectors
• Data Logger section to store waveforms to hard drive
Acquisition: The "Acquisition" indicator is green when data is being acquired and red when the
acquisition is stopped.
HINT: Typing values in the Offset fields is easier than using the knob.
CH1 and CH2: The channel 1 and channel 2 buttons are used to turn on and off channels 1 and 2.
The color of the buttons matches the color of the trace.
V/Div CH1 and CH2: Set the volts per division for each input independently by using the V/Div
arrows or by selecting a value from the V/Div field.
30 ISSUED: March 2003 901217-01
Operation
Offset CH1 and CH2: Set the Offset for each input independently using the Offset knob or by typing a value in the Offset field. The Offset knob will change color depending on the channel
selected: yellow when channel 1 is selected and red when channel 2 is selected. These colors
also match the trace colors in the graphics display.
Bandwidth Limit CH1 and CH2: To suppress high frequency noise on waveforms, limit the bandwidth of the digitizer by selecting a 20 MHz or 200 MHz filter. This function smooths the displayed
waveform by blocking frequencies above the filter’s limit.
Coupling CH1 and CH2: Each channel of the digitizer is set to DC coupling by default so that AC
and DC signals appear on the display. Select AC coupling (in the Trigger control section) to view
the AC signal only. Clicking the switch control toggles the selection.
T/Div: The time per division is set by using the T/Div arrows or by selecting a value from the T/Div
field. The Digitizer automatically adapts itself to use the maximum sampling rate whenever the
timebase is changed.
Delay: Turn the Delay knob to adjust the horizontal position and the amount of pre-trigger, as
desired.
Number of Points: This is an indicator that displays the number of points in each acquisition. This
will vary automatically depending on the T/Div.
Sample Rate: This is an indicator that displays the sample rate for each acquisition. This will vary
automatically depending on the T/Div.
901217-01 ISSUED: March 2003 31
PXD Series Digitizer
Source: The trigger source for the digitizer may be either of the input channels or the PXI Trigger
and Star Trigger lines on the PXI backplane.
Coupling: This sets the trigger coupling for the input channels. DC is used when all the signal
components (AC and DC) are coupled to the trigger circuit. When AC is selected, the signal is
capacitively coupled, DC levels are rejected, and frequencies below 50 Hz are attenuated.
Level: Defines the source voltage at which the trigger circuit will generate an event.
Slope: Determines the direction of the trigger voltage transition used to generate a particular trig-
ger event.
Modifier: In NORM mode the digitizer will acquire while there is a valid trigger. In AUTO mode the
trace will automatically be displayed regardless of a valid trigger. When a valid trigger is present in
Auto mode, the Digitizer will behave as if in Normal mode.
On/off: Turns datalogging on and off.
Directory: Sets the directory for storing waveforms. Entering a period sets the current directory of
the Quick-Start Demo; entering another value (e.g., "Test 1") creates a new folder called "Test1"
referenced from the current directory.
Filename: Sets prefix for the filename.
Index: An auto-incrementing index is appended to the filename. When the datalogger is turned on,
and the program is in Continuous Acquisition mode, each waveform will be stored.
USING THE PXD SERIES DIGITIZER IVI INSTRUMENT DRIVERS
The CD-ROM includes several example programs written in LabWindows/CVI using the PXD
Series IVI driver. Even if you are not using CVI, the ".c" files provide practical examples that will
help you learn how to program the Digitizer.

MULTI-MODULE SYNCHRONIZATION
The PXD digitizers support PXI extensions to the PCI bus for the following backplane clock and trigger
capabilities:
• External clock input for module synchronization to the 10 MHz TTL clock provided by the PXI backplane
(PXI_CLK10).
• Trigger inputs to support an asynchronous low skew (1–5 ns) trigger source broadcast on the PXI star
trigger bus.
• Asynchronous trigger I/O to support a single-line broadcast on the PXI trigger bus. The trigger input may
come from an external source, or from a digitizer module. Digitizer modules provide a tri-stated output to
support this mode, with high impedance guaranteed on power-up.
Software Compatibility:
The PXD hardware is compatible with the following software environments:
Operating Systems: Windows 2000/XP
