CompuScope 1220 connectors and headers
CompuScope cards connect to the outside world through connectors, both analog (BNC) and digital (PCI Bus,
Master/Slave, etc.). This section describes these connectors for the CS1220 card.
The connectors and headers on the CS1220 card are shown below:
Figure 2: Connectors on CS1220
•
Channel A BNC
Connector for the single-ended input of channel A; used to input an analog signal that
is sampled as Channel A.
•
Channel B BNC
Connector for the single-ended input of channel B; used to input an analog signal that
is sampled as Channel B.
•
External Clock connector BNC
Connector used to supply an signal that will be used as the sampling
clock instead of the CompuScope card’s own oscillator.
•
External Trigger BNC
Connector used to input an analog or digital signal, which may be used as an
External Trigger. External Trigger is defined exactly as in an oscilloscope: this signal can be used to
trigger the system but cannot be viewed or digitized.
•
Master/Slave connector
The Master/Slave connector is located near the top edge of the CompuScope
1220 card. In case of an Independent card (i.e. a card not upgraded to either a Master or a Slave), this
connector may not be present.
The Master/Slave Timing Module is used to pass all the signals necessary to synchronize Slave
CompuScope 1220 cards with the Master.
NOTE FOR COMPUSCOPE 1220 DEEP MEMORY BOARD USERS:
IF Y-CABLES ARE NOT CONNECTED BETWEEN THE POWER CONNECTORS OF YOUR
COMPUSCOPE DEEP MEMORY CARD(S) AND THE POWER SUPPLY OF THE CHASSIS, THE DEEP
MEMORY CARD(S) WILL NOT FUNCTION PROPERLY.
