Signature Control: Controls when the output will be present. See also: "Signature
Control" on page161.
Frequency: The frequency of the output: 1MHz, 5MHz or 10MHz, depending on the
card model.

Option Cards" on page292.
5.2.3.5 Programmable Frequency Out [1204-13, -2F, -30]
Programmable Frequency Output option modules provide output square waves at pro-
grammable pulse rates, or sine waves at programmable frequencies. The output fre-
quency, which is adjustable via the SecureSync Web UI, is locked to the SecureSync
system-disciplined oscillator.
These option cards can be used for a variety of applications requiring programmable fre-
quency outputs. The RS-485 model of this card can be operated as an N.8 frequency syn-
thesizer.
Depending on your card model number, the outputs are available in different formats:
RS-485 on a pluggable terminal block
TTL square wave on BNC, or
Sine wave on BNC
Each output can be phase-offset between 0-360° in 0.1°-increments.
