Chapter 2 Assembling Your Instrument
Connecting a DMC to a base unit
T-BERD/MTS/SC Getting Started Guide
March 2018 22046537, Rev. 016 Page 33
The DMC is connected to the base unit. It is completely assembled, and can be used
for testing.
Before testing using the DMC, you must insert the MSAM(s) and the appropriate PIMs
or the CSAM(s) for the circuits you intend to test. For details, see
“Inserting MSAMs or
CSAMs into the 6000A base unit or DMC” on page 35 and “Inserting, removing, and
swapping PIMs in the MSAM” on page 37 .
Connecting two DMCs to a base unit
If you intend to connect two DMCs to a base unit for testing, verify that you are using
an AC power adapter that can support your instrument assembly. To discuss the vari-
ous power adapters available for your instrument, contact Viavi Customer Care, or
contact Viavi via the company web site,
www.viavisolutions.com .
Disconnecting the DMC
Before disconnecting the DMC from the base unit, review the “Key principles” on
page 28 for assembling the instrument. The same principals apply when disassembling
the various components.
Required tools
Large, flat blade screwdriver
You will need a large, flat blade screwdriver to remove the battery module.
Hex key (provided)
A 5 mm hex key is provided in a groove on the inside panel of the battery module. This
key is used to secure and then tighten the screws that connect the module to the base
unit.
Torque wrench (optional)
If you want to ensure that you don’t apply too much pressure when connecting or
disconnecting components, you can optionally use a torque wrench capable of applying
13.3 in-lb. A torque wrench with the ability to apply up to 20 in-lb in 0.1 in-lb increments
will be adequate. You will also need a 5 mm hex key bit for the wrench.
Disassembling the instrument
To remove the DMC from a base unit
1 Verify that power is OFF on your base unit and that the power adapter is
unplugged.
