CH SEL CH00~CH03
CH04~CH07
CH08~CH0B
CH0C~CH0F
Threshold CMOS/(2.5V)
voltage LVCMOS3.3/(1.7V)
LVCMOS2.5/(1.3V)
LVCMOS1.8/(0.9V)
Custom
Voltage 0～4.09V( forward
by 0.01V pace)
For example, Measure a batch of CMOS voltage data signal in channel of
CH00~CH03 and a batch of 1V voltage data in CH04~CH07. Threshold voltage
setting steps as below:
A、Press "1 (threshold) "and menu appears.
B、Press "F1" till channel source display as "CH00~CH03"
C、Press "F2" to choose threshold as "CMOS/（2.5V）"
D、Press "F1" till channel source display as "CH04~CH07"
E、 Press "F2" to choose threshold as "custom". Menu setting correspond to F3
display the setting voltage value.
F、Turn "CH1 Volts/div" knob and set voltage value as "0.50V"
Threshold voltage setting finished (refer to fig. 75).
Instruction
16 channels can be divided into 4 groups to
have individual setting
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.
In custom, the voltage can be set from 0V to
4.09V with the pace of 0.01V.
