Hardware Installation
Dual Channel HF Search and Collection (N6830)
shows a configuration that provides two independent N6830 HF search and
collection systems in a 5-slot chassis (MFRAME1).
Figure 2.
HF
search and collection
Note
The two HF search and collection systems are totally independent of each other. In this
configuration, two instances of the E3238S application run in the same computer, so only one
software license is required.
Data is passed to the E9821 DSP via the fiber-optic FPDP (front-panel data port) interface.
See
Fiber Optic Cabling of the DSP Module on page 28
for more information.
Note
The external reference input is used by both channels. When using the external reference
input, both e3238s.cfg files must have the same setting for the searchRx1.adcClock
parameter (External). The E3238S application that is started last will always override the
searchRx1.adcClock parameter setting of the E3238S application started first.
Depending on the PMC modules installed on the E9821 DSP boards, both instances of the
E3238S can perform search and provide 32 channels of narrowband channelization for
collection. At least one 32-channel digital downconverter (DDC, option 200) is required for
narrowband channelization. See
. Additional E9821 DSP
boards can be added to the system to provide additional narrowband channels.
Note
The typical E9821 DSP configuration for most signal types is one dual G4 processor (option
101) for each 32 channel digital downconverter (DDC, option 200). With this configuration,
each additional E9821 DSP module adds 64 digital downconverters for narrowband
channelization.
The block diagram for this configuration appears in
.
Installation of the controller and firewire interface is discussed on
Setting address switches:
• N6830 address settings appear on
.
• Switch settings for the E9821 are on
