Safety Warnings
WARNING: This unit contains lethal AC voltages. Disconnect the unit
from the AC supply before removing the cover.
WARNING:
The lightning flash with an arrowhead inside of an equilateral triangle is intended to alert
the user to the presence of un-insulated “dangerous voltage” within the product’s
enclosure. The “dangerous voltage” may be of sufficient magnitude to constitute a risk of
electrical shock to people.
CAUTION:
The exclamation point inside of an equilateral triangle is intended to alert the user to the
presence of important operation and maintenance instructions in the user guide.

2General Description
The FTSU-100D is a high performance signal distribution amplifier designed for use with the Brandywine
model PTS Precision Time System.
The FTSU-100D is contained in a compact IU rack-mount chassis. The FTSU accepts two sets of inputs. An input set
comprises a 10 MHz reference frequency, a 1PPS signal and status inputs from the reference generator. The FTSU-
100D provides automatic changeover should one of the source inputs fail. Manual source select override is available
on the front panel. A variety of status indicators are located on the front panel for visual feedback.
The low phase noise frequency outputs are generated from a low phase noise oscillator that is phase-locked to the
reference frequency input. In the event of a reference input failure,the phase –locked oscillator will continue to
provide referenced frequency outputs with a stability of 3 x 10-9over temperature.

3Unpacking and Installation
3.1 Unpacking
Carefully remove the FTSU-100D from the shipping carton. The following items should be included in the
shipment: •1 FTSU-100D
•1 power cord
•1 user guide
Note the power entry module on the rear of the FTSU-100D chassis. Please take note of the voltage
displayed on the rear of the power entry module and verify that the voltage matches the local line’s voltage.
Insert the provided power cord into the rear of the power entry module and connect the power cord to an
AC power outlet.
CAUTION:
THE FTSU-100D WILL BE DAMAGED IF THE INCORRECT AC LINE SETTING IS USED.
WARNING:
REMOVE THE POWER CORD FROM THE FTSU-100D BEFORE
ADJUSTING THE LINE VOLTAGE.
If the AC line setting is incorrect, detach the power cord from the power entry module. Use a small
screwdriver to lift up the fuse cover on the power entry module to remove the fuse holder. Reverse the fuse
holder and re-insert the fuse holder, making sure that the correct AC line voltage is now displayed on the
rear panel.
3.2 Installation
The FTSU-100D may be bolted directly into a 19” rack mount enclosure or mounted by rack mount slides.
The FTSU-100D, when fully populated, has up to 30 cables attached to the rear panel, therefore it is
recommended that some appropriate cable strain-relief system be used to support these cables,
particularly when not using rack mount slides.
