Buffer status
The buffer reading status attribute includes the status information as a numeric value; see the
following table for values. For example, to access status information for the second element of SMU
channel A buffer 1, use the following command:
stat_info = smua.nvbuffer1.statuses[2]
Buffer status bits
Bit Name Hex value Description

Measure range was autoranged
Source range was autoranged
4-wire (remote) sense mode enabled
Source function in compliance
Dynamic reading buffers
Reading buffers can also be allocated dynamically. Dynamic reading buffers are created and
allocated with the smuX.makebuffer(n) command, where n is the number of readings the buffer
can store. For example, the following command allocates a reading buffer named mybuffer that can
store 100 readings:
mybuffer = smua.makebuffer(100)
Allocated reading buffers can be deleted as follows:
mybuffer = nil
Dynamically allocated reading buffers can be used interchangeably with the smuX.nvbufferY
buffers that are described in Dedicated reading buffer designations (on page 3-11
).
