MONITOR OUTPUT ARCHITECTURE

The figure above illustrates the functionality of the dScope's Monitor Outputs. Operation of the monitor system is through the Monitor Outputs dialogue box shown below:



The Monitor Outputs comprise two BNC connectors for each of the dScope's Signal Generator and Analyzer, plus a stereo headphone output and integral loudspeaker.

The BNCs have a 75R output impedance and are generally intended for connection to an oscilloscope or external audio monitoring system. They can output various audio, carrier or trigger signals as selected by the operator. Audio signals are usually automatically ranged to a nominal level between 2Vp–p and 4Vp–p (unterminated), although the gain can be manually set if required. Carrier signals are attenuated to half their input amplitude. In 'pulse' mode, audio signals can be sliced at their zero-crossings to provide TTL output pulses.

Audio signals selected to the BNC Monitor Outputs can also be monitored in mono or stereo at the headphone socket, or in mono on the integral loudspeaker, which share a volume control on the dScope front panel.
