Remote digital I/O commands
Commands for both SCPI and TSP are summarized in the following table. You can use the digital I/O
port to do the following actions:
• Perform basic steady-state digital I/O operations, such as reading and writing to individual I/O
lines or reading and writing to the entire port
• Trigger the Model 2461 when external trigger pulses are applied to the digital I/O port
• Provide trigger pulses to external devices
SCPI command
TSP command Description
:DIGital:LINE<n>:MODE (on page 6-35)
This command sets the mode of the digital I/O line to
be a digital line, trigger line, or synchronous line and
sets the line to be input, output, or open-drain.
digio.line[N].mode (on page 8-50)
A line reset is not available in SCPI; however, the line is
reset when a global reset (
*RST
) is sent
This command resets digital I/O line values to their
factory defaults.
digio.line[N].reset() (on page 8-52)
:DIGital:LINE<n>:STATe (on page 6-36)
This command sets a digital I/O line high or low when
the line is set for digital control and returns the state
on the digital I/O lines.
digio.line[N].state (on page 8-53)
:DIGital:READ? (on page 6-37)
This command reads the digital I/O port. All six lines
must be configured as digital control lines. If not, this
command generates an error.
digio.readport() (on page 8-53)
:DIGital:WRITe <n> (on page 6-38) This command writes to all digital I/O lines. All six
lines must be configured as digital control lines. If not,
this command generates an error.
digio.writeport() (on page 8-54)
:TRIGger:DIGital<n>:IN:CLEar (on page 6-211) This command clears the trigger event on a digital
input line.
trigger.digin[N].clear() (on page 8-241)
:TRIGger:DIGital<n>:IN:EDGE (on page 6-211) This command sets the edge used by the trigger
event detector on the given trigger line.
trigger.digin[N].edge (on page 8-242)
:TRIGger:DIGital<n>:IN:OVERrun? (on page 6-212)
This command returns the event detector overrun
status.
trigger.digin[N].overrun (on page 8-243)
Not available in SCPI
This command waits for a trigger.
trigger.digin[N].wait() (on page 8-243)
Not available in SCPI
This command asserts a trigger pulse on one of the
digital I/O lines.
trigger.digout[N].assert() (on page 8-244)
:TRIGger:DIGital<n>:OUT:LOGic (on page 6-213)
This command sets the output logic of the trigger
