Kit Description
NOTE. The following conventions apply throughout this document:
HThe MTG100 and MTG300 MPEG Generator is simply referred to as the
“MPEG generator.”
HThe MPEG generator is referred to as being either a “standard” or
“Option 1R” version. The “standard” MPEG generator does not include
rackmounting hardware. The “Option 1R” MPEG generators have
rackmounting hardware on the sides of the instrument’s cabinet.
The MTG100 and MTG300 Rackmount (Option 1R) Upgrade Kit provides parts
and instructions for you to perform the following tasks:
HReplace the standard cabinet on your MPEG generator with an Option 1R
(rackmount ready) cabinet
HInstall the MPEG generator into a standard 19-inch equipment rack
If your MPEG generator was ordered with Option 1R, Tektronix shipped the
MPEG generator with the rackmount cabinet already installed. If this is your
case, you will need to perform only the instructions for mounting your MPEG
generator into an equipment rack.
Products
NOTE. A standard equipment rack has rails with universal hole spacing. If your
equipment rack uses hole spacing that is different than universal hole spacing,
you may have to drill additional mounting holes in the rack to accommodate the
mounting hardware included in this kit.
CAUTION. Mounting the MPEG generator into an equipment rack requires
certain minimum clearances around the instrument. Be sure to read the
information in Environmental Requirements before you install the MPEG
generator into an equipment rack.
If you rackmount the MPEG generator using methods that are different than
those described in these instructions, the MPEG generator may not meet its
warranted specifications.

This section contains the following procedures:
HAssembling t he slide-out tracks
HInstalling the slide-out track assemblies
Installation Instructions
Assembling the
Slide-out Tracks
HRackmounting the MPEG generator
The slide-out tracks permit the rackmounted MPEG generator to be extended out
of the equipment rack for rear-panel and connector maintenance without
removing the MPEG generator from the rack.
WARNING. To prevent personal injury and equipment damage, if you disassemble
the slide-out track assemblies for maintenance, do not interchange the inner left
and right tracks when you reinstall them into the outer left and right tracks.
If you interchange the inner left and right tracks, you will defeat the extension
stop (safety latch) feature of the tracks. The MPEG generator could, when
extended, come out of the slides and fall from the equipment rack, possibly
causing personal injury and equipment damage.
NOTE. The slide-out track assemblies included in the rackmount kit come
partially assembled with the inner tracks attached inside of the outer tracks.
Leave the track assemblies partially assembled to simplify their installation and
to avoid accidentally swapping their inner tracks. (See WARNING above.)
When the left and right slide -out tracks are correctly assembled and oriented as
shown in Figure 6 on page 15, the round cutout is below the square cutout at the
end of the both inner tracks.
MTG100 and MTG300 Rackmount Upgrade Instructions

Installation Instructions
Perform the following procedure to assemble the slide-out tracks:
1. Identify the right and left slide-out track assemblies:
a. Find the date code label on each track assembly.
b. The track assembly to be mounted on the left side of the equipment rack
(the side of the rack nearest the left side of the MPEG generator (see
Figure 3 on page 10)) has a date code that ends with “LH,” for left hand.
c. The track assembly to be mounted on the right side of the equipment
rack has a date code ending with “RH,” for right hand.
2. Measure the distance between the front and rear rails of the equipment rack.
3. Align one of the rear brackets to the right slide-out track assembly as shown
in Figure 6.
NOTE. The rear brackets have multiple pairs of mounting holes. When you align
the rear bracket and the slide-out track, be sure to select a pair of holes that
mount the rear bracket so that the flange-to-flange distance (see Figure 6)
matches the front to rear rail measurement from step 2.
4. Use a screwdriver with a #2 Pozidrive tip to secure the rear bracket to the
right slide-out track using two screws (10-32) and a bar nut as shown in
Figure 6. Leave the screws loose so that the overall length of the slide-out
track assembly can be adjusted when you install it in the rack (refer to step 4
on page 17).
5. Repeat steps 3 and 4 to assemble the left slide-out track assembly.
