Faceplate Indicators and Connectors

Faceplate Indicators

"Failed" turns on momentarily during the function generator's power-on self-test. If the function generator successfully establishes internal communication, the indicator turns off. If the function generator fails to establish internal communication, the indicator remains on.

"Access" turns on only when the resource manager is communicating with the function generator.

"Errors" turns on only when an error is present in the function generator's error queue. The error can result from improperly executing a command or the function generator being unable to pass a part of self-test or calibration. Use the SYST:ERR? command repeatedly to clear the error queue. A response of +0,"No error" indicates the error queue is empty. See Appendix B, Agilent E1441A Function Generator Error Messages, for a list of all errors.

"Overload" turns on when the function generator senses a signal applied to the output terminal that exceeds the present output level. The output terminal is disconnected while the "Overload" light is on.

Option 001 Phase-Lock 10 MHz Reference Terminals

These connectors allow synchronization between multiple Agilent E1441As or to an external 10 MHz clock signal. Additionally, option 001 allows phase offset control.

Standard Input/Output Terminals

The function generator's faceplate contains the following terminals: 1. External Trigger/FSK/Burst modulation input terminal

2. Sync signal output terminal for all standard output functions

3. AM Modulation input terminal

4. Output terminal

Note The outer shell of the "Ext Trig/FSK/Burst" BNC connector is connected to chassis. All other BNC connectors are floating.
