The frequency offset at the carrier frequency is determined by the formula:
Δ
fc = Fc x
Δ
fs
where:
Δ
fc = carrier offset
Fc = carrier frequency
Δ
fs = offset of 10 MHz standard (from the tables)
3.3.2.3 Output
Options
Several output options are available to configure the Frequency Outputs for various
applications. The output options are listed below. Refer to Section 5, Options and
Accessories, for a complete description.
•
Option 03, Built-in Distribution Amplifier
•
Option 06, 12.8 MHz Outputs
•
Option 07, 5 MHz Outputs
•
Option 16, 1PPS on the third and fourth rear panel frequency outputs
3.3.3 1544 kHz and 2048 kHz Timing Outputs
Each of these RJ-11 receptacles provide an RS-485 Timing Output of the indicated
frequency. The output signals, 1544 kHz and 2048 kHz, are synthesized from the 10
MHz GPS disciplined oscillator. Major Alarm relay contacts are included on each output
connector.
NOTE:
Simulcast Offsets affects the accuracy of the timing outputs.
The connector pin numbering is shown in Figure 3-5 and pin assignments listed in Table
3-4.
