Source measure cycle (source & measure at 1 ms minimum)

As shown in the figure below, the GS610 is capable of synchronizing the generation and measurement at any operation mode. Generation is started after a source delay with respect to an internal/external trigger. Then, after the time it takes for the source level to stabilize (measure delay) the measurement is carried out over a given integration time. This function is necessary when making measurements by waiting for the load response after applying a pulse. The source measure cycle is the minimum unit for signal generation and measurement. The source/measurement operation (source measurement cycle) on the GS610 is 1 ms minimum.

Difference measurement using the sweep operation

The sweep operation can be used to make two measurements, then the difference between the two measurements can be determined. When the source value of sweep data 1 is established, the first measurement is carried out. Then, when the source value of sweep data 2 is established, the second measurement is carried out. The difference is determined by subtracting the value of the second measurement from that of the first measurement. By carrying out the two measurements within a short time, highly accurate measurements are possible with the effects of offset fluctuation cancelled. In addition, by applying a voltage with equal magnitude but opposite in polarity (source 1 = -1× source 2), the effects of offset error caused by the thermo electromotive force at the junction can be cancelled.
