Parameter Channel Offset level
1/2 CH1/2 ±0.5~
±5 ±0.5V ~ ±5V
(2mV/div~50mV/div)
±5.0~
±50 ±5.0V ~ ±50V
(100mV/div~500mV/div)
±50.0~
±300 ±50.0V ~ ±300V
(1V/div ~ 10V/div)
Example :channel1:scale 1.00e–2
:channel1:offset 2.00e–2 Sets the Channel 1
scale to 10mV/div
Sets the Channel 1
offset to 20mV
