is a standard feature. In addition, remote
control and status monitoring via a network port is available as an option. The FDC3302 is unique in the industry - no other low-cost system
offers this combination of capabilities and performance in a single product.
Output Signal Quality
The FDC3302 features low-signal distortion and added phase noise along with
high isolation between output channels. Power supply voltages are post-regu-
lated and all output buffers are individually regulated, ensuring very low output
spurious noise levels.
Autoswitching
The FDC3302 can be configured for single or dual input operation. If two inputs
are available then the FDC3302 will monitor the input signals. If an input is
removed or the amplitude is greatly reduced it will automatically switch to the
other input. This feature ensures that your critical signals are always present.
Alarm Input
The FDC3302 is compatible with the alarm output signal from the Meridian
Precision GPS TimeBase and the Tycho Frequency Reference. If one of these units is sourcing the FDC3302 and its alarm output goes active,
then the FDC3302 will automatically switch to the backup source. Since this alarm input may be cascaded to multiple FDC3302 units simply,
using BNC T-adapters and coaxial cable, multiple FDC3302 units can be bank switched.
Status Indicators
Front panel LEDs provide you at-a-glance status of the distribution chassis. The FDC3302 provides LED indicators for the power supply(ies), the
two inputs, all output signals and a summary alarm indicator. The summary alarm is also available as an open-collector output on a rear-panel
BNC.
Control and Status Monitoring
The FDC3302 can be configured and monitored by means of an RS-232 serial port. Both switch status and output status can be monitored in
this way. For remote control and monitoring, a network port is available as an optional upgrade.
Options
The FDC3302 Frequency Distribution Chassis can be configured for one input or two inputs with autoswitch. Two inputs is the factory default.
An additional option is the capability of having dual redundant, AC or DC power supplies. The two power supplies can be any combination
of AC/AC, AC/DC, or DC/DC. A network port that can be used for remote control and status monitoring is also available with a full suite of
network protocols.
Two-Year Warranty
The FDC3302 Frequency Distribution Chassis is backed by a full two-year warranty against defects in material and workmanship.
Money-Back Guarantee
If your FDC3302 does not meet your time and frequency distribution needs for any reason, simply return it within 60 days for a full refund.
