Test Program.
😆 find gpib0 board Open a board-level connection
IBSTA: 0 to a GPIB-ENET whose hostname
IBERR: 0 is gpib0. This should put me
IBCNT: 0 at the board level.
BOARD-> sic Interface Clear
IBSTA: 0
IBERR: 0
IBCNT: 0
BOARD-> cmd "@?\x22" @ is My Talk Address 0 (gpib0)
IBSTA: 0 ? is Unlisten All
IBERR: 0 \x22 is Hex 22 which is My
IBCNT: 0 Listen Address 2 (the primary
address for my-instrument).
BOARD-> wrt "*IDN?" standard SCPI command that most
IBS
TA: 130 instruments should understand.
IBERR: 1 Since I set up the talkers and
IBCNT: 0 listeners, the device at
primary address 2 will
get that command and respond.
BOARD-> cmd "? B" ? is Unlisten All
IBSTA: 0 space is MyListen Address 0
IBERR: 0 B is My Talk Address 0
IBCNT: 0
BOARD-> rd 100 This command reads the stuff
on the bus sent from Device
Buffer = 2. It shouldrespond with
something like
"Hewlett Packard Oscilloscope"
IBSTA: c164 or something like that, but
IBERR: 6 it does not?
IBCNT: 0
ibwrt "FREQ 500 kHz" This command write data to
IBSTA: 0 the device addressed above
IBERR: 0 This does not work either
IBCNT: 0
Can anyone tell me what I am doin
g wrong?
