Getting Started
Required Tools
•A non-metal prying device
•A 5/32” (4mm) nut driver or socket wrench
•A 5/16” (8mm) open-ended wrench, nut driver or socket wrench
•T8 TORX driver
Packaging and GPSDO Kit Contents
Your FLEX-6000 GPSDO will arrive in an anti-static package similar to the one shown below.
Remove the contents and verify that the following items are included before proceeding. Refer to the
image below.
•One (1) GPS patch antenna
•One (1) GPSDO assembly
•Two (2) coax assembly cables (one cable may be shorter)
•Two (2) threaded 5/32” (4mm) spacers

Preparing to Install the GPSDO Module
The back panel plugs and top cover must be removed before the GPSDO can be installed.
Removing the Back-Panel Metal Plugs
Place the FLEX-6000 on its feet with the back facing you as shown in the image below.
Using your fingernail or another non-metal prying device, remove the two (2) metal plugs from the back
panel below the labels:
•GPS ANT
•10 MHz OUT

Removing the Top Cover
The top chassis cover for the FLEX-6000 must be removed before the GPSDO can be installed.
Using the T8 TORX driver remove the four (4) short Top Cover screws on the FLEX-6000.
Then remove the remaining five (5) short Side Cover Side screws from each of the right and left sides of
the FLEX6000. Retain the screws for re-installation. The images below show the Side Cover screws.
Once the top cover retaining screws have been removed, gently pull the Top Cover upwards to remove it
from the FLEX-6000.

Installing the GPSDO Assembly in the FLEX-6000
Once the top cover and chassis plugs have been removed, the GPSDO module can be installed into the
FLEX-6000.
Installing the Internal Coax Cabling
Locate the long coax cable assembly (if there is a longer one in the kit) and remove the SMA connector
cap, hex nut, and lock washer.
Slightly bend the coax at the SMA connector end of the assembly to facilitate inserting the threaded end
of the coax cable assembly through the back-chassis hole labeled 10MHZ OUT. This is the hole located in
the far right-hand corner of the back-panel chassis.
While firmly holding the long cable assembly in place with one hand, install the lock washer on the
threaded SMA connector. Carefully install the SMA connector 5/16” (8 mm) hex nut on the threaded SMA
connector being careful not to cross-thread the SMA connector. Tighten the hex nut with your fingers so
that the coax cable assembly will freely rotate.
Insert the threaded end of the short coax cable assembly (if there is a shorter one in the kit) through the
back-chassis hole labeled GPS ANT at the center-right of the back-panel chassis.
While firmly holding the short cable assembly in place with one hand, install the lock washer on the
threaded SMA connector. Carefully install the SMA connector 5/16” (8 mm) hex nut on the threaded SMA
connector being careful not to cross-thread the SMA connector. Tighten the hex nut with your fingers so
that the coax cable assembly will freely rotate.

Installing the GPSDO Module Assembly
The next step is to install the GPSDO module assembly into the FLEX-6000.
If installed, remove the GPSDO RF shield from the module housing by gently prying it upwards on all four
sides evenly as shown below. Be careful not to bend the retaining teeth by prying up one side more than
another.
Gently lift off the shield as shown below.

In the left rear of the FLEX-6000 TRX circuit board, locate the area where the GPSDO module will be
installed. It is clearly marked adjacent to a ribbon cable and Ethernet jack.
Orient the GPSDO module assembly so that the TCXO (large rectangular silver component on the PC
board) is facing the rear of the FLEX-6000.
Insert the GPSDO module assembly onto the printed circuit board so that the two (2) threaded screw
studs are visible inside the GPSDO assembly as shown below. When oriented correctly, press down firmly
to properly seat the GPSDO assembly module.

Carefully thread a 5/32” (4mm) spacer onto each threaded stud as shown in the image below, making
sure not to cross-thread the stud.
Using a 5/32” (4mm) socket wrench or nut driver gently tighten the spacers on the threaded stud to firmly
attach the GPSDO assembly module to the printed circuit board. Do not over tighten the threaded spacer.

Press the 10MHZ OUT coax assembly onto the MMCX connector on the GPSDO assembly module closest
to the front of the FLEX-6000 as shown below.
Press the GPS ANT coax assembly onto the MMCX connector on the GPSDO assembly closest to the back
of the FLEX-6000 as shown below.
Replace the RF shield on the top of the GPSDO assembly module making sure that it is pressed down
firmly, as shown below, to prevent EMI leakage.

Orient the coax assemblies, as shown above, lying as flat as possible. While holding the coax assembly in
one hand, use either a 5/16” (4mm) open-ended wrench, socket or nut driver as shown below to slightly
tighten the SMA connector hex nut to prevent the SMA connector from rotating.
Tighten the SMA retaining nut on both coax assemblies.
Be careful not to scratch the back panel of the FLEX-6000 when tightening the SMA connector hex nuts.
Reinstalling the Top Cover
Replace the top chassis cover on the FLEX-6000. Orient the cover so that the row of vent holes on the top
cover is facing towards the front of the FLEX-6000 as shown below.
