43.3. How to set threshold
Threshold setting is quite important because wrong setting will result in wrong measurement. For example, if
measure signal is LVCMOS1.8V and set threshold as “CMOS/(2.5V) ” then all the measurement data will
become “0”. Threshold setting menu refer to Fig. 89.
Fig. 89 Threshold setting menu
Threshold menu function as below:
Function
Setting
Instruction
CH SEL
CH00~CH03
CH04~CH07
CH08~CH0B
CH0C~CH0F
16 channels can be divided into 4 groups to have individual setting
Threshold
voltage
CMOS/(2.5V)
LVCMOS3.3/(1.7V)
LVCMOS2.5/(1.3V)
LVCMOS1.8/(0.9V)
Custom
CMOS level and set threshold voltage as 2.5V
LVCMOS3.3V level and set threshold voltage as 1.7V
LVCMOS2.5V level and set threshold voltage as 1.3V
LVCMOS1.8V level and set threshold voltage as 0.9V
Level can be set discretionarily.
Voltage
-10 ~ +10V (forward
by 0.05V pace)
In custom, the voltage can be set from -10V to +10V with the pace of
0.05V.
