DC: ±( 2 mV + [ ((( 4 * (Vertical Scale Voltage)) / ( Absolute Input Voltage) ) + 1 )% of
Absolute Input Voltage ] + (0.5% of Absolute Offset Voltage))
DC example: an input channel set up w ith +2 V offset and 1 V/div measuring a –5 V
signal would have ±( 2 mV + [((( 4 * 1 ) / 5 ) + 1 )% of 5 V] + [0.5% of 2 V] ) = ±(
2 mV + [1.8% of 5 V] + [0.5% of 2 V] ) = ±( 2 mV + 90 mV + 10 mV ) = ±102 mV.
This is roughly ±2% of the input voltage.
AC:±2%(40Hzto1kHz)
AC (typical): ±2% (20 Hz to 10 kHz)
For AC m easurements, the input channel vertical settings must allow the V
