4.3.12.6 Programming I/O port functionality
– Ext. I/O Setup
The
Ext. I/O Setup
allows you to select the
function of the instrument’s
I/O
socket. This
socket can work as:
•
output of the analogue signal (
Analog
)
transmitted from the input channel of the
instrument (
Channel
) to its output without
any digital processing (i.e. frequency
filtering);
<ENT>
•
input of the digital signal used as an external trigger to start the measurements
(
Digital In
). The i
nstrument acts in this case as a so called “slave instrument”.
The
Function
parameter is set to
Ext. Trigger
;
•
digital output (
Digital Out
) used for triggering another “slave instrument” (the
instrument is acting in this case as a “master instrument”) (
Trigger Pulse
), or
as a source of any alarm signal in the case of certain events occurred during
the measurements (i.e. the alarm lamp) (
Alarm Pulse
).
If
Function
is set to
Trig. Pulse
the
Polarisation
parameter appears on the
screen. Polarisation of the trigger pulse can be
Positive
or
Negative
.
