DDS 100 Reference Information
CAMBOARD Electronics
You can perform the following updates and repairs to the DDS 100 in the
field:
• Installing a firmware update (see below).
• Replacing the AC fuse (see page B-4)
Before completing either of these procedures, follow the instructions in
"Internal access", below.
Updates and fuse replacement require access to the internal areas of the
DDS 100. To access the internal areas, do the following:
1. Remove the power cable from the DDS 100.
Do not open the cover of the DDS 100 without unplugging the power
cord.
2. If the DDS 100 is rack mounted, remove the input and output cables
from it, remove the unit from the rack, and remove the rack
mount brackets (see figure 12). (If the DDS 100 is not rack
mounted, you do not need to remove the input and output
cables.)
