Probe connection (connector X5)
Either a 5 V or a 24 V probe may be connected.
Characteristics of probe inputs X5:
5V probe input
Typical value 0,25 mA. ? Vin = 5 V.
High threshold (logic state 1) VIH: From +2.4 V DC on.
Low threshold (logic state 0) VIL: Below +0.9 V DC.
Maximum nominal voltage Vimax = +15 V DC.
24 V probe input
Typical value 0,30 mA. ? Vin = 24 V.
High threshold (logic state 1) VIH: From +12.5 V DC on.
Low threshold (logic state 0) VIL: Below +4 V DC.
Maximum nominal voltage Vimax = +35 V DC.
The unit has two probe inputs (5 V DC and 24 V DC) at connector X5.
Depending on the connection being used, it is possible to choose whether it is activated by the up flank or
by the down flank of the probe (see section
DRO:
).
