Balun Output Adapter Panel
Symmetricom offers three Balun Output Adapter panels for use with 2048 kHz and
E1 Output modules. One adapter panel is required for each Output module in the
shelf. You need one Output cable (see Adapter Accessories, on page 221, for a list
of available cables) to connect the Adapter panel to the shelf.
The Balun Output Adapter panel (part number 22013068-001-0) uses BNC
connectors. Figure 8-26 shows an I/O Adapter with Balun outputs.
The Balun Output I/O Adapter panel (part number 22013068-002-0) uses Siemens
1.6/5.6 mm connectors.
The Balun Output I/O Adapter panel (part number 22013068-003-0) uses Siemens
1.0/2.3 mm connectors.
