Triggering the Transmission

The Data Modulation mode starts by setting the output frequency to 0 Hz and awaiting a trigger condition. When a trigger condition occurs, the unit will turn on the carrier and modulate the carrier until all bits have been sent out. After the message has been transmitted, the 4071 will turn off the carrier and await another trigger event. The 4071 will simultaneously accept a trigger from these three sources:

1.Pressing the Trigger key

2.Applying a low-to-high transition on the Ext Trig In connector

3.Sending an ASCII "T" to the RS-232 port

Saving the Message

You may save the downloaded message by saving the instrument setup using the STORE/RECALL button. Up to 10 instrument setups (including 10 messages) may be stored. Modulation data messages are only saved when the unit setup is stored in Internal FSK mode.
