Operational Timing
2. Restrictions on setting
•
The 6240B has a Tsync time delay of approximately 30
s from the external trigger input to the
measurement start. This delay is increased to approximately 50
s in the low-resistance meas-
urement pulse source mode. Consider this time delay when using two or more 6240B units in
synchronous operation.
•
For all three units, set the measurement range to Fixed and auto zero to OFF.
•
Using the external trigger has restrictions on setting Tp and Th for slaves. (Refer to Section
5.2.11.1).
•
The first synchronous sweep step has a gap within the Th accurate range.
