Multi-Channel Hardware Installation
General Configuration
searchRxConfiguration
: MultiChannelParallelTimeSynchronousSearch
specifies the multi-channel search mode; all channels sweep the same frequency range.
numSearchRx
specifies the number of search receiver channels installed.
searchRxAdcSynchronization
specifies whether the ADC clock and Sync signals
are passed from one ADC to the next via the VXI backplane or the ADC front panel
connectors. The default is
vxiBackplane
.
Tuner Configuration
Each channel (searchRx1, searchRx2, etc.) has a set of tuner parameter settings:
• The first parameter is the
logical address
for the downconverter module.
• The second parameter specifies the
10 MHz reference
source.
• 0 selects the internal reference. This is the default setting.
• 1 selects the external reference connection on the tuner’s front panel.
• 2 selects the external reference on the VXI backplane. This is from the controller and
requires configuring the controller to provide it properly.
• The third parameter specifies the tuner’s
settling time
.
• The fourth parameter specifies the
lowest frequency
to which the downconverter can tune
(MHz). The default is 20 MHz but the lowest possible setting is 2 MHz. Note: The E2730
model does not perform well in the HF region. There are significant spurs and distortion
components below 20 MHz.
