SRQ on error

This example shows you how to generate an SRQ when an instrument error occurs.

Using SCPI commands:

Using TSP commands:

-- Clear Error Queue so EAV bit can go low.

errorqueue.clear()

-- Clear the status byte

status.clear()

-- Enable SRQ on error available

status.request_enable = status.EAV

-- Send a line of code that will generate an error

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:

STAT:OPER:MAP 0, 4918, 4917

STAT:OPER:ENAB 1

TRAC:POIN 100, "defbuffer1"

SOUR:VOLT:RANG 1

SOUR:VOLT:ILIM 10e-3

READ? "defbuffer1"

TRAC:DATA? 1, 100, "defbuffer1", READ
