• Combining of the Bit Data
The data of LogicA and LogicB can be combined and handled as 16-bit data.
• Handling of the OFF Bit
• In binary notation, a dash is displayed at the bit.
• In hexadecimal notation, value is displayed as though the bit does not exist.
Measurement Example of Logic Waveforms
The values of measurement parameters Y1 and Y2 when the logic waveform is
measured using vertical cursors are as follows.
• When LogicA or LogicB is measured by itself and OFF bits do not exist
