5.2 Time and Frequency Option Cards
5.2.5.4 Programmable Frequency Output: Edit Window
To configure a Programmable Frequency Output , go to its Edit window. For instructions, see:
"Configuring the Settings of an Input or Output" on page 290.
The Web UI list entry for this card is: Prog Freq Out, Sine [or: TTL, or: RS-485, respectively].
The connector numbers are: J1...J4 [J1 for the RS-485 model].
The Edit window allows the configuration of the following settings:
Signature Control : Controls when the output will be present. See also: "Signature Control"
on page 201.
Frequency : Enter the desired output frequency. The ranges are as follows:
Phase : Adjust the phase by entering a phase offset (0.1 to 360°), if required.

SecureSync starts numbering I/O ports with 0 (only 1PPS and 10 MHz out-
NOTE –
puts start at 1, because of the built-in outputs).
Sine wave output frequency (model no. 1204-13): 1 to 25,000,000 Hz
Pulse rate output in Hertz (model no.'s 1204-2F/-30): 1 to 25,000,000 PPS
NOTE – The phase offset will lose its reference at a SecureSync reboot, and hence
the value will be reset to 0 (ZERO).
The reference will also be lost if you enter a new output frequency for a port – how-
ever in this case, the value will not be reset to 0, but instead remain unchanged. In
both cases you will need to re-enter the required phase offset value.
