SRQ when reading buffer becomes full
This example shows you how to generate an SRQ when the Model 2450 reading buffer is full. This is
useful to notify the controlling computer that it needs to read back the data and empty the buffer. After
configuring the status model, this code configures the default reading buffer 1 to a size of 100, and
then configures the SMU to fill the buffer. After the buffer is full, the instrument generates an SRQ and
returns the data.
Using SCPI commands:
*RST
STAT:CLE
STAT:OPER:MAP 0, 4918, 4917
STAT:OPER:ENAB 1
*SRE 128
TRAC:CLE
TRAC:POIN 100, "defbuffer1"
SOUR:VOLT:RANG 1
SOUR:VOLT 1
SOUR:VOLT:ILIM 10e-3
COUNT 100
OUTP ON
READ? "defbuffer1"
OUTP OFF
TRAC:DATA? 1, 100, "defbuffer1", READ
