Preface
Preface
The Tektronix PED3200/PED4000 Series Error Detectors are instruments that
accept a clock and an NRZ data stream. Given the contents of the expected data
(PRBS or programmable user data), they can count errors and report the bit error
ratio. They includes various features to assist in setting the sampling point and
synchronizing the incoming pattern to the internal reference pattern.
Features
The Tektronix error detectors provide the following features:
3Gb/sto32Gb/soperation(PED3200series)
3Gb/sto40Gb/soperation(PED4000series)
Fully integrated bench-top instrument
AC or DC coupled differential data inputs (can be used single-ended)
Available with 1 or 2 input channels
Independent data on each channel
User-defined patterns or built-in PRBS patterns
Full rate AC coupled clock input (can be used single-ended)
Auto adjustment or manual adjustment of data to clock phase
Auto synchronization to input pattern
Touch screen graphical user interface (GUI) and USB TMC interfaces
3RU height, full-rack design

Getting Started
Installation
The error detector was carefully inspected electrically and mechanically before
shipment. After unpacking all items from the shipping carton, check for any
obvious signs of physical damage that may have occurred during transit (there
may be a protective film over the display, which can be removed). Report damage
to the shipping agent immediately. Save the original packing carton for possible
future shipment.

Power requirements
CAUTION. Operating the instrument on an incorrect line voltage can cause
damage, possibly voiding the warranty. To avoid this, operate the instrument
with the correct line voltage.
The instrument operates from a single-phase line voltage shown in the following
table. Line voltage and line frequency are automatically sensed; there are no
switches to set. Check to ensure the operating voltage in your area is compatible.
Table 1: Power requirements
Item Description
Voltage 100 V to 240 V
Frequency 50 Hz to 60 Hz
Power 360 W, maximum
Power fuse T 2 A 250 V
The power cord supplied with the instrument contains a separate ground for use
with grounded outlets. When proper connections are made, the instrument chassis
is connected to power line ground through the ground wire in the power cord
providing protection against electric shock.
PED3200/PED4000 Series Programmable Error Detector User Manual 1

Getting Started
Ventilation The instrument has four fans in the rear, as well as cooling vents on the bottom
and side panels to keep it from overheating.
CAUTION. Inadequate ventilation can damage the instrument; to avoid damaging
the instrument, observe the following precautions:
Do not block the cooling vents.
Do not position any devices adjacent to the instrument that force air (heated or
unheated) into or onto the instrument surfaces or cooling vents. This additional
airflow could compromise performance.
When rack mounting the instrument, ensure there is adequate airflow around the
instrument rear, sides and bottom to ensure proper cooling. Adequate airflow
enables air temperatures within approximately one inch of the instrument surfaces
to remain within specified limits under all operating conditions.
Environmental
considerations
The following table describes the maximum operating environmental ratings for
your instrument.

Feature Description
Temperature 40 °C (104 °F)
Humidity 80% for temperatures up to 31 °C (88 °F) decreasing linearly to 50%
