PD-5 Description

SDI

The PD-5 is a TTL pulse distribution amplifier that accepts one input and
provides five outputs. The outputs are designed to drive low impedance loads and long
50 or 75-ohm cables. The propagation delay through the amplifier is typically 10 ns.
The channel-to-channel delay differences are less than 1 ns. The small propagation
delay characteristics and low temperature coefficient of delay are essential for the
distribution of high quality timing signals. The instrument is available in a 3.5” X 8.4” X
12 “ enclosure. The PD-5 can be combined with either a second PD-5 or a one pulse
per second generator model PPS-2 to form a standard 19” rack mountable instrument.

Safety and Preparation for Use

SDI

CAUTION!

Voltages capable of causing injury or death are present in this instrument. Use extreme
caution whenever the instrument cover is removed.

Line Voltage

This instrument may be setup to operate on 100-120 or 220-240 VAC and a line
frequency of 50 to 60 Hz. Locate the power entry module and disconnect the power
cord. The voltage of operation is displayed on the power entry module. If it reads 115
the unit is setup for 100-120 VAC operation. If 230 is displayed the unit is setup for
220-240 VAC operation. To change the line voltage of operation use a flat-blade screw
driver to carefully remove the plastic cover of the power entry connector. The cover
should swing down towards the IEC power socket. Note you cannot change the voltage
setting with the power cord still attached to the unit. Remove the red fuseholder and
rotate to select the desired line voltage. The fuse must be replaced too. Insert the
fuseholder and replace the plastic cover. The selected line voltage setting will be
displayed on the power entry module

Fuse

A 0.5 Ampere 250V slow-blow fuse is used for 100-120 VAC operation.
A 0.25 Ampere 250V slow-blow fuse is used for 220-240 VAC operation.
Only replace fuses with the same type and specifications.

Line Cord

The instrument has a detachable, three wire power cord for connection to a grounded
power source. The enclosure of the unit is directly connected to the outlet ground to
protect against electrical shock. Always use an outlet with a protective ground and do
not disable this safety mechanism.

Service

Do not attempt to service or adjust the instrument unless another person, capable of
providing first aid or resuscitation, is present. Contact SDI for any questions or repairs.

Operation

To operate the unit, locate the AC power entry connector on the rear panel and connect
the power cable. When power is applied to the unit, a red led located on the front panel,
labeled “on”, should light up.
