Frequency: Enter the desired output frequency. The ranges are as follows:
Sine wave output frequency (model no. 1204-13): 1 to 25,000,000Hz
Pulse rate output in Hertz (model no.’s 1204-2F/-30): 1 to 25,000,000PPS
Phase: Adjust the phase by entering a phase offset (0.1 to 360°), if required.
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 –
however 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.
Programmable Frequency Output: Status Window
To view the settings of a Programmable Frequency Output, go to its Status window. For instruc
tions, see: "Viewing Input/Output Configuration Settings" on page329.
The Web UI list entry for this card is named: Prog Freq Out, Sine [or: TTL, or: RS-485, respect
ively].
The connector numbers are: J1…J4 [J1 for the RS-485 model].
Note: SecureSync starts numbering I/O ports with 0 (only 1PPS and 10MHz out
puts start at1, because of the built-in outputs).
The Status window displays the following settings:
