UTG4000A Operating Manual

Set sending mode

Automatic and manual sending can be set. In the state of automatic sending, the 

instrument sends the set protocol coding in certain time; in manual mode, the instrument 
sends the set protocol signal when users press the send key.

1) Automatic sending mode
Press soft function key SendMode to adjust to “AUTO” to set automatic sending mode 

of the instrument. You can set the send time. Press soft function key Send Time to set send 
time with numeric key.

2) Manual sending mode
Press soft function key SendMode to adjust to “Manual” to set manual sending mode of 

the instrument. Press soft function key Send, the instrument will output the set waveform.
