Notes
Inputs
Disabled - IO connector is disabled.
In-AccumulationEnable Level
This signal controls the execution of the
averaging sequence.
-AVG IO 1 only
In-TriggerEnable Level
Digitizer
mode
IO 2 only.
In-BScanSync Pulse SS-OCT application: B-scan Trigger Input. -SS4/SS5 IO 2 only
In-CScanSync Pulse SS-OCT application: C-scan Trigger Input. -SS4/SS5 IO 3 only
Outputs
Out-LowLevel Level Fixed 'low' level signal for debug purposes.
Out-HighLevel Level Fixed 'high' level signal for debug purposes.
Out-AScanSync Pulse
SS-OCT application: A-scan Trigger Output
(Requires -SS4 option).
IO 1 only.
Out-AScanEna Level
SS-OCT application: A-scan Trigger Enable
(Requires -SS4 option). If High, the card is
processing A-scans
IO 1, 2 or
3.
Out-AScanUp Level
SS-OCT application: A-scan Trigger Up
(Requires -SS4 option). Used to distinguish
source up/down (forward/backward sweeps).
IO 1, 2 or
3.
Out-BScanSync Pulse
SS-OCT application: B-scan Trigger Output
(Requires -SS4 option).
IO 2 only.
Out-CScanSync Pulse
SS-OCT application: C-scan Trigger Output
(Requires -SS4 option).
IO 3 only.
Table 5.3 - List of signals selectable for the programmables I/Os .
The list of Available signals is indicated (as a comma separated list) by member
IAqMD3ControlIO.AvailableSignals (IVI.NET) or attribute AQMD3_ATTR_CONTROL_IO_
AVAILABLE_SIGNALS (IVI-C).
Signal Logic Levels
The multi-purpose IO signals are 3.3 V CMOS compatible (5V Tolerant buffer). The levels shown in
the table below should be observed.
