VXI11 protocol functions
Function name
Channel
Meaning
create_link()
core
Opens a link to a network instrument device, setting up socket connections for the
core and abort channels, but not for the interrupt channel.
destroy_link()
core
Cancels a link to a network instrument device.
device_write()
core
Sends an IEEE 488.2 or SCPI command as a string to a network instrument device
.
device_read()
core
Reads responses from a network instrument device
.
device_readstb()
core
Reads the status byte of a network instrument device
.
device_trigger()
core
Triggers a trigger in a network instrument device and is equivalent to *TRG.
device_clear()
core
Triggers a "device clear" (DCL) in a network instrument device. In the R&S NRP,
DCL and abort have the same effect. Because
device_abort()
, unlike
device_clear()
, is transmitted over the abort channel, it is not serialized with
other commands but goes directly to the device and is therefore preferable.
device_remote()
core
Changes the network instrument device to the remote state.
device_local()
core
Changes the network instrument device to the local state.
device_lock()
core
LLO (local lock out). The keyboard of the network instrument device is locked.
device_unlock()
core Cancels
the
LLO
state.
device_docmd()
core
The network instrument device executes a command.
device_abort()
abort
The network instrument device aborts an in-progress command.
See
device_clear()
.
create_intr_chan()
core
An interrupt channel to the network instrument device is set up.
destroy_intr_chan()
core
An existing interrupt channel to the network instrument device is cleared down.
device_enable_srq()
core
The sending of service requests from the network instrument device to the network
instrument controller is activated/deactivated.
device_intr_srq()
interrupt
This is the only function that the network instrument server calls from the network
instrument device. It signals a service request (SRQ)
.
