4.12 Synchronized Operation, Serial Connection, and Parallel Connection
Synchronized operation, serial connection, and parallel connection for use of multiple 6243/44 units are
explained in the following.
4.12.1 Synchronized Operation
The synchronized operation of the 6243/44 units requires synchronization of measurement timing in the
DC source mode, and also requires synchronization of both source and measurement in the Pulse source
mode and the Sweep source mode.
The timing control for the synchronization is performed by the external control signals of TRIGGER IN,
SYNC OUT, COMPLETE OUT and the setting of time parameters such as Measure Delay and Source
Delay. For details on these timings, refer to Section 4.11, “External Control Signals.”
The following explains an example of synchronized operation using the BUSY signal.
When using the BUSY signal, there are following features.
• The source and measurement steps are matched with the slowest.
• Despite source or measurement range changes taking place, synchronization is still possible in every
step. (However, the timing of source measurement cannot be synchronized if a range change is
made.)
Figure 4-23 shows a connection diagram and timing chart for synchronized operation using the BUSY sig-
nal. This example shows synchronization of 6243/44 No. 2 and No. 3 by the signal from 6243/44 No. 1 in
the Pulse source mode. Also, the Operate/Standby status is controlled by the Operate Signal.
