Datasheet

Trigger settings:
Bit 1 & 0 Trigger mode (00 = Normal / 01 = Auto / 10 = Once)
Bit 2 Trigger slope (0 = rising edge / 1 = falling edge)
Bit 3 Trigger channel (0 = ch1 / 1 = ch2)
Bit 4 Run/Hold (0 = run / 1 = Hold)
Bit 5 Reserved
Bit 6 Reserved
Bit 7 Autorange (0 = autorange off / 1 = autorange on)
Bit 8…15 Reserved
Checksum: CHKSUM = 8-bit two’s complement of sum of all previous bytes

Remark:
Se ng the autorange:
• The Y-posi on and trigger level is forced to the center posi on.
• Triggermode is set to auto mode.
• The  mebase and V/div will be automa cally set to fi t the waveform on screen.
• The V/div will be automa cally set for the channels to fi t the waveform on screen.
Into autorange:
Changing the Y-posi on, trigger level, trigger mode, V/div or Timebase must switch the autorange off
