If you have FORMat[:DATA] set to REAL or SREAL, you will have fewer options for buffer elements.
If you request one of the buffer elements, you will see the error 1133, "Parameter 4, Syntax error,
expected valid name parameters."
Example
TRAC:MAKE "buf100", 100
TRIGger:LOAD:LOOP:SIMPle 5, 0, "buf100"
SOUR:VOLT 0.35
INIT
TRAC:DATA? 1, 5, "buf100", READ, SOUR, REL
TRAC:DATA? 1, 5, "buf100", READ, REL
TRAC:DATA? 1, 5, "buf100", REL
TRAC:DATA 1,3
Create a buffer called buf100 with a maximum
size of 100.
Set the instrument to configure the trigger model to
loop, taking 5 readings with no delay, and store the
readings in the buf100 reading buffer.
Set the source level for voltage to 0.35.
Initiate the trigger model, which will make
5 readings and store them in buf100.
Read the 5 data points, reading, programmed
source, and relative time for each point.
Output:
-0.000000,0.350000,0.000000;
-0.000000,0.350000,0.266978,
-0.000000,0.350000,0.443087,
-0.000000,0.350000,0.704459,
-0.000000,0.350000,0.881419
Read 5 data points and include the reading and
relative time for each data point.
Output:
-0.000000,0.000000,
-0.000000,0.266978,
-0.000000,0.443087,
-0.000000,0.704459,
-0.000000,0.881419
Read 5 data points and include relative time for
each data point.
Output:
0.000000,0.266978;0.443087,
0.704459,0.881419
Returns the first 3 reading values from
defbuffer1 reading buffer
Output:
-0.000000,-0.000000,-0.000000
