Return to
smuX.nvbufferY.appendmode
X = SMU channel (a or b)
Y = NV buffer (1 or 2)
Attribute
Append mode for the reading buffer.
Usage
state = smuX.nvbufferY.appendmode
-- Reads append mode.
smuX.nvbufferY.appendmode = state
-- Writes append mode.
Set
state
to one of the following values:
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.
Remarks
• Assigning to this attribute enables or disables the buffer append mode.
• With append mode on, the first new measurement will be stored at
rb[n+1]
, where
n
is the number of readings stored in the buffer.
Details

” in this section and in

Example
Append new readings for SMU A to contents of buffer 1:
smua.nvbuffer1.appendmode = 1
smuX.nvbufferY.basetimestamp
X = SMU channel (a or b)
Y = NV buffer (1 or 2)
Attribute
Timestamp of when the first reading was stored from time of power-up.
Usage
basetime = smuX.nvbufferY.basetimestamp
Remarks
• Reading this attribute returns the timestamp (in seconds) for the first reading
(
rb[1]
) stored in a buffer. The timestamp is based on the number of seconds from
power-up that the measurement was performed and stored.
• This is a read-only attribute.
Details
See “
” in this section and in
.

Example
Read the timestamp for the first reading stored in buffer 1 of SMU A:
basetime = smua.nvbuffer1.basetimestamp
print(basetime)
Output:
2.03
The above output indicates that the timestamp is 2369.9 seconds.
