 V
OLTAGE
You can set any threshold level in the range of 10.0 V to +10.0 V. To
adjust the threshold, you can move the entry focus to the value.
EXT-IN Impedance Parameter (50
Ω
/10k
Ω
)
Toggle the input impedance of the EXT INPUT connector between 50
Ω
and 10 k
Ω
.
CLK-IN Parameter
Move the entry focus to CLK-IN to quickly set the triggering threshold of
the clock input connector (CLK IN) to a TTL or ECL-compatible level.
