Buffervar.appendmode - Keithley 2651A Reference Manual

Section 7: Command reference
Usage
result = bit.toggle(value, index)
result
value
index
Details
This function returns result, which is the result of toggling the bit index in value.
Any fractional part of value is truncated to make it an integer. The returned value is also an integer.
The least significant bit of value is at index position 1; the most significant bit is at index position 32.
The indexed bit for value is toggled from 0 to 1, or 1 to 0.
Example
testResult = bit.toggle(10, 3)
print(testResult)

Not applicable
The reading buffer append mode; set to one of the following:
•
0: Append mode off; new measure data overwrites the previous buffer content
•
1: Append mode on; appends new measure data to the present buffer content
The reading buffer; can be a dynamically allocated buffer (user-defined), or a
dedicated reading buffer (such as smua.nvbuffer1)
The binary equivalent of decimal 10 is 1010.
Toggling the bit at index position 3 returns a
decimal value of 14 (binary 1110).
Output: 1.40000e+01
Where saved Default value
