Explanation
Types of Logic Probes
Select the logic probe from 700986, 700987, 702911, and 702912.
Input Signal Type
If the logic probe is 702911 or 702912, select the input signal type.
TTL
TTL level voltage signal:
Indicates 1 at a voltage greater than equal to approximately 1.4 V.
CONT
Voltage-free contact signal:
Indicates 1 when signal is shorted to the earth line.
Bit Display ON/OFF (Display Bits)
You can specify whether to display the waveform for each bit.
Bit Label
Alphanumeric characters that can be entered: Up to 8 characters
Bit Mapping
Fixed
A space is allocated for bits that are turned OFF.
Auto
A space is not allocated for bits that are turned OFF.
Only the bits that are turned ON are displayed in order from the top.

Note
If you are observing the logic channel waveforms measured on the SL1400 using a software
application such as XViewer or if you are reading the logic channel data using the WAVeform
communication command, set the logic probe type of both LogicA and LogicB the same. If they
are not the same, correct waveforms may not be displayed or correct data may not be output.
