Status IN Indicator (green)
Status OUT Indicator (red)
External Event Input Connector
Only apply signals within the stipulated
range to the external event input connector.
Voltages that exceed this range may damage the
P3420.
HighĆImpedance Control Input Connector
Only apply signals within the
stipulated range to the highĆimpedance
control input connector. Voltages that
exceed this range may damage the
P3420.
Data Output Connector
Rear Panel
If external voltages are applied to the
data output connectors, be sure to set the
highĆimpedance control correctly so that signal
collisions do not result in output currents or voltages
in excess of the rated values.
CONTROLĂINPUT
The CH0 to CH11 connectors output pattern data with
variable output levels in the range -3 to +7 V. The delay
times for channels CH8 to CH11 can be varied from 0 to 20
ns. These are SMB connectors.
This indicator lights when signals are being output
from the data output connector.
Data Input Connector
Connect the DG2020A data output connector to the
P3420 data input connector using a pod connection
cable.
For inputting an external event signal to be used for
sequence control. This is an SMB connector.
For inputting an inhibit signal that switches the
data outputs to the highĆimpedance state.
This indicator lights when INHIBIT and EVENT inputs
are enabled.
