Appendix A: Specifications
This section contains the specifications for the AVG1 Generator module.
Table A--1 lists the electrical specifications, and Table A--2 lists the EMC
compliance specifications. All specifications are guaranteed unless labeled
“typical.” Typical specifications are provided for your convenience, but are not
guaranteed.
Specifications are only valid when the module is installed in a TG 2000 Platform
mainframe.
For a list of environmental specifications, refer to the TG 2000 Signal Genera-
tion Platform User Manual .
