4601 I-V Meter Operation Manual
5.6.1 Synchronous Operation
5-38
2. Restriction on Setting
•
The 4601 has a Tsync (approx. 25
s) time delay from the external trigger input to the measure-
ment start. Set this time delay according to the following formula 1. when using more than one
4601 in synchronous operation.
•
Slave Tp and Th have restrictions on using the external trigger.
•
The first synchronous sweep step has a gap within the Th accurate range.
•
Tp in synchronous operation has the following minimum value restrictions:
Master Tp
500
s Slave Tp
200
s
Therefore, consider Tsync time and set the relevant setting as follows:
1. Tds1
Tds2 + Tsync (25
s)
2. Td1
Td2 - Tsync (25
s)
3. Tp1
Tp2 + TA
(Tp1
500
s, Tp2
200
s)
