4.1 Burst oscillation
WF1943B 4-11
Other settings:
• At the above settings, when the waveform is squarewave, a three squarewave is obtained such as
shown in the following figure.
• Internal gate source : A 50 % duty gate signal is generated at the following period for
oscillation start/stop.

• Stop level off : Oscillation stops at the half-cycle after gate signal off (i.e., at the phase set by
ENTRY
→
PHASE
).
• Manual gate signal : Press the
MAN TRIG
key. The gate signal is on (i.e., oscillation) while the key
is pressed. In this case, set the trigger source for EXT L-ON.
• To generate the trigger signal via remote control (GPIB or USB), set the TRG command from the
remote control interface.
Also, set the trigger source to EXT L-ON.
For details of the remote control command,
