PST & PSS & PSH SERIES PROGRAMMABLE POWER SUPPLY

PROGRAMMER MANUAL

⎯ 45 ⎯

Queues

The output queue is included to power supplies.

Output Queue: The programmable power supplies store query responses

in the output queue by succeeding the IEEE 488.2 protocol. If the power

supply receives a new command or query message after a message

terminator, the power supply will clear and reset this queue each time.

The computer must read a query response before it sends the next

command (or query) or it loses response to earlier queries.

Error/Event Queues

When an error or event occurs, the output queue stores the message. The

output queue stores and reports the messages on a FIFO (first in first out)

state. The SYSTem:ERRor? query reads the next item from the output

queue. If output queue overflows, the error message is –350, “Queue

overflow”; the queue can’t store or report succeeding messages till it

is read or cleared.

Error Message

Table 8 lists the SCPI error messages for the programmable power

supplies.
