There are four inputs on the rear of the instrument - two signal and two DC
control. The inputs are a primary source (A) and a secondary source (B). These
sources are switched, dependant on the control input, one for the primary (A)
and the other for the secondary (B).
The control lines are 0 ~ 5v DC
active high (+5v DC).
Output
There is one single
signal output on the rear panel. This is the output from either signal input,
dependant on the control input
Typical uses
The Quartzlock A4000 is installed in many
remote, unmanned telecommunications base stations to ensure continuous time and
frequency standards are available for mission critical applications.
