Abstract: An electricity supply apparatus includes a control device configured to calculate an amplitude of a control signal and to generate the control signal; an energy station configured to draw a current from a mains, to provide part of the drawn current to the load, to receive the control signal from the control device, and to vary the drawn current according to the amplitude; and a battery configured to recharge by drawing part of the drawn current and to discharge by supplying the load. The apparatus is characterized in that the control device is further configured to calculate the amplitude of the control signal also according to battery information relating to a recharge and/or a discharge condition of the battery.

Abstract: The instrument measures directly the phase jitter of analog signals emitted n the line by the device under test, even when clock information is not available and when particular specifications and limitations do not allow the use of analog instruments. It uses a circuit which generates a square-wave clock signal with the same phase and frequency characteristics as the signal to be measured, so as a phase comparison with a reference signal can be made. Error signal obtained is filtered, measured and displayed.
