Installing the Output Module in
the DTG5000 series Data Timing Generator
The DTG5000 Series Data Timing Generator mainframe and output module(s) are shipped separately.
The DTGM10, DTGM20, DTGM21, DTGM30, DTGM31 and DTGM32 are output modules that can
be used with the DTG5000 mainframe. These modules can be used in any combination and in any slot.
There are functional differences between slot A though slot D and slot E though slot H. Refer to the
Mainframe and Output Configuration subsection in the DTG5000 User Manual. It is recommended
that you use slot A when only one output module is installed in the mainframe.
Electrostatic Discharge
To prevent electrostatic damage to the DTG5000 Series output modules, follow the precautions
described below.
CAUTION. Output modules are inherently vulnerable to a static damage.
Be sure to operate the output module in a static-controlled environment. If the
output module is not going to be in use for an extended period of time, attach
the connector caps and SMA termination (DTGM30, DTGM31, DTGM32) to
the output module. Store the output module in the antistatic bag. The
connector caps and SMA terminations (DTGM30, DTGM31, DTGM32) are
provided with your output module.
Installing an Output Module
To install the output module, first turn off the instrument using the front panel On/Standby switch.
CAUTION. To prevent damage to the output module or mainframe, never
install or remove an output module when the mainframe is powered on. Avoid
touching the board surface or connectors with your fingers when you handle
the module. Attach the blank panel to the slot(s) when the output module(s) are
not installed.
1. Verify that the data timing generator mainframe is not powered on.
2. Remove the blank panel from the mainframe slot.
3. Align the output module with the slot.
4. Gently push the output module into the slot using firm pressure.
5. Once the module is seated, tighten the two screws with either a flat head or a Philips
screwdriver to secure the module to the mainframe. To prevent damage to the module, use a
torque screwdriver and tighten the screw to the range of 25 to 35 N-cm ( 2.2 in lb to 3.1 in lb ).

Removing an Output Module
Verify that the data timing generator mainframe is not powered on.
1. To remove an output module from the mainframe, first turn off the instrument using the
On/Standby switch.
2. Loosen the two screws.
3. Grasp the right and left screws and slowly pull the module out of the the mainframe.
4. Attach a blank panel to the slot(s).
Signal output Connector Care
Never attach a cable to signal output connectors if the cable has a worn or damaged connector because
you may damage the output module connector. Use extra care when attaching or removing a cable
from the connectors. Turn only the nut, not the cable. When attaching a cable to an output module
connector, align the connectors carefully before turning the nut. Use light finger pressure to make this
initial connection. Then tighten the nut lightly with a wrench.
CAUTION. For best repeatability and to prolong the life of both connectors,
use a torque wrench and tighten the connection in the range of 79-112 N-cm
(7 in lb to 10 in lb ).

the DTG5078 or the DTG5274, applies to firmware version1.xx. You have to
upgrade the OS by using attached the Windows2000 Recovery Disk. Please refer
to Appendix B “System Recovery” in User Manual.
