Multifunction I/O
Screen that enables configuring the instrument's I/O port
parameters: I/O Mode, Direct, D/A, Function, Slope,
Polarisation, Active Level, Source, Source Type, Alarm
Level, Send SMS and Send E-Mail.
Detailed description of the I/O port is given in
Appendix C.
Chapter
7.10
Appendix C
I/O Mode
Mode of the I/O port: Analog Out, Digital In, Digital Out.
Chapter
7.10
Appendix C
Analog Out
Mode of the I/O port when analogue signal is transmitted
from the input of the instrument to its output (pin 1 of the
I/O connector) without any digital processing (Direct) or
after digital-to-analogue converter (D/A).
Chapter
7.10
Appendix C
Direct
Parameter that enables the measured signal from the
measurement channel to be transmitted to the pin 1 of
the I/O connector without any digital processing (filtering
and gaining).
Chapter
7.10
Appendix C
D/A
Parameter that enables transmitting the analogue signal
from the internal signal generator of the instrument after
digital-to-analogue converter to the pin 1 of the I/O
connector, and the analogue input signal to the pin 2 of
the I/O connector after digital-to-analogue converter.
The input signal can be weighted with HP, Z, A, C or B
filter (Source) and additionally gained by -60 dB to 60 dB
(Gain).
Chapter
7.10
Appendix C
Digital In
Mode of the I/O port when external digital signal is used
as an external trigger to start measurements. The
instrument is acting in this case as so called “slave
instrument”.
Chapter
7.10
Appendix C
Slope
Trigger voltage slope defined for the Digital In I/O mode:
[+] (uprising as default) or [–] (falling).
Chapter
7.10
Appendix C
Digital Out
Mode of the I/O port when digital signal is used for
triggering other “slave instrument(s)” (the instrument is
acting in this case as a “master instrument”), or as a
source of alarm signal.
Chapter
7.10
Appendix C
Function
Functionality of the Digital Out I/O mode: Trigger Pulse
or Alarm Pulse.
