Remarks
• Assigning a
state
value to this attribute enables or disables the storage of source
values. Reading this attribute returns the
state
of source value collection.
• When on, source values will be stored with readings in the buffer. This requires four
extra bytes of storage per reading.
• This value, off or on, can only be changed when the
buffer is empty. The buffer can be
emptied using the
function.

Example
Include source values with readings for SMU A buffer 1:
smua.nvbuffer1.collectsourcevalues = 1
smuX.nvbufferY.collecttimestamps
X = SMU channel (a or b)
Y = NV buffer (1 or 2)
Attribute
Timestamp collection for the buffer.
Usage
state = smuX.nvbufferY.collecttimestamps
-- Reads collection state.
smuX.nvbufferY.collecttimestamps = state
-- Writes collection state.
Set
state
to one of the following values:
0
Timestamp collection disabled (off).
1
Timestamp collection enabled (on).
Remarks
• Assigning a
state
value to this attribute enables or disables the storage of
timestamps. Reading this attribute returns the
state
of timestamp collection.
• When on, timestamps will be stored with readings in the buffer. This requires four
extra bytes of storage per reading. The first reading is timestamped at zero seconds.
Subsequent readings are timestamped relative to the time storage was started.
• This value, off or on, can only be changed when the
buffer is empty. The buffer can be
emptied using the
function.

Example
Include timestamps with readings for SMU A buffer 1:
smua.nvbuffer1.collecttimestamps = 1
smuX.nvbufferY.n
X = SMU channel (a or b)
Y = NV buffer (1 or 2)
Attribute
Number of readings in the buffer.
Usage
bufferreadings = smuX.nvbufferY.n
Remarks
• Reading this attribute returns the number of readings that are stored in the buffer.
• This is a read-only attribute.
