Hallo,
I have some questions according to the accuracy of the measurement functions:
1. What is the accuracy for a subtraction of two channels using
":FUNCtion<N>:SUBTract <operand>,<operand>" command:
a) dc Voltage Measurement Accuracy, Dual Markers = ±[(dc gain accuracy)+ (resolution)]
b) dc Voltage Measurement Accuracy, Single Marker = ±[(dc gain accuracy) + (offset accuracy) + (resolution/2)]
2. What is the accuracy for the sum of two channels using
":FUNCtion<N>:ADD <operand>,<operand>" command:
a) dc Voltage Measurement Accuracy, Dual Markers = ±[(dc gain accuracy)+ (resolution)]
b) dc Voltage Measurement Accuracy, Single Marker = ±[(dc gain accuracy) + (offset accuracy) + (resolution/2)]
The Programmer's Reference gives no information about the accuracy of the implemented functions and measurements at all and the description in the data sheet is not clearly understandable.
Regards,
Christoph

It describes the how the data is coerced from the 8bit ADC to final
form(ASCII,WORD,BYTE). The primary component in accuracy of the Math functions will be the DC gain of the ADCs.
