Front Panel Indicators

Failed LED: Illuminates momentarily during digitizer power-on.

Access LED: Illuminates when the backplane is communicating with the digitizer.

Error LED: Illuminates only when an error is present in the digitizer’s driver error queue. The error can result from improperly executing a command or the digitizer being unable to pass self-test or calibration.

Sample LED: Illuminates while the digitizer samples the input for a measurement. Typically blinks for slow sample rates and is on steady-state for high sample rates.

User Input Terminals

The E1564A Digitizer front panel contains four female connectors for user inputs. Mating male connectors are supplied with the module. However, the user must provide the input cable and connect the male connector to the cable. See "User Cabling Considerations" for connecting user-supplied cables.

External Trigger Input/Calibration Bus Output

The front panel contains a 9-pin D-subminiature connector for external (TTL) trigger inputs and for calibration bus outputs. The E1564A

4-Channel Digitizer has a calibration bus output (High, Low and Guard) and a programmable short. The user must provide the the appropriate cable to the external trigger input/calibration bus output.
