Appendix D: Installation

D- 6

AWVG1 Wideband Video Generator User Manual

Figure D- 6: Top screw

10.

Reinstall the top cover and insert and tighten all top cover screws.

11.

Plug in the instrument power cord. Power on the mainframe by setting the
rear-panel power switch to ON and pressing the front-panel power switch.
Wait for the instrument to perform self tests.

12.

If you previously moved or removed a module and backed up the signal sets,
you can reinstall them now, using the

Signal Set Installation

procedure.

If this module was installed in the TG 2000 Platform mainframe at the factory,
signal sets are already installed. If you ordered this generator module separately,
you must install signal sets after installing the module. (If you have another
AWVG1 Generator module already installed in the platform, the new module
you install can share its signal sets, and you do not need to install them again.)

To install signal sets, use either of the two following procedures:

Installing

Signals to the Default Destination

or

Installing Signals to a Non-default

Destination

. To replace signal sets, refer to the

TG 2000 Signal Generation

Platform User Manual
