1. On/Off switch - Depress the power switch to apply power to the
Analyzer488.
2. Power Supply connector - Plug the cable from the external power supply
into this jack.
3. Trigger Output - When the trigger point event is recorded by the
Analyzer488, the trigger output will transition from a low (0) to a high (1)
logic level and stay high.
4. RS-232 Port - Connect a 9 pin RS-232 cable to this connector to use the
Analyzer488 with a serial host or serial printer.
5. Edge Card Connector - All IEEE 488 bus lines are brought out to this
connector for use with an oscilloscope or logic analyzer. Also a compare
(CMP) output is provided that pulses whenever the trigger match pattern
appears on the bus
6. IEEE 488 Connector - Connect a standard IEEE 488 cable to this
connector to use the Analyzer488 with other bus devices.
