To Set the Label
To identify different data buses conveniently, you can set another label for each
digital channel. You can use the preset label or input the label manually.
Press Sel CH to select the digital channel which needs label and you can select any
channel from D0-D15.
Press Sel Preset to select the preset labels (ACK, ADO, ADDR, BIT, CAS, CLK, DATA,
HALT, INT, UB, LOAD, NMI, OUT, PIN, RAS, READY, RESET, RX, TX or WR).
You also can press Input Lab to open the label input interface and input the label
manually. For specific input method, please refer to the instruction in “
Channel
Label”.
Delay Calibration
When using an oscilloscope for actual measurement, the transmission delay of the
probe cable may bring great error (zero offset). MSO4000/DS4000 allows users to
set a delay time to calibrate the zero offset of the corresponding channel. Zero offset
is defined as the offset of the crossing point of the waveform and threshold level line
relative to the trigger position.
Press Delay-Cal and use to set the delay calibration time and the range
available is from 100 ns to -100 ns.
