Square-wave Output
Square- wave output is a unique function for many applications, such as
pulse width modulation (PWM) output, adjustable voltage control, and
synchronous clock (baud rate generator). You can also use this function to
check and calibrate flow- meter displays, counters, tachometers,
oscilloscopes, frequency converter, frequency transmitter, and other
frequency input devices.
Selecting square-wave output
1 Press to select the square- wave mode. When the U3606A is
operating in the square- wave mode, the square- wave annunciator
( ) on the front panel is illuminated.
2 The default frequency is 600 Hz, as shown on the upper secondary
display. Press again to cycle through the amplitude, duty cycle,
and pulse width values. (The default amplitude is 0 V, the default duty
cycle is 50%, and the default pulse width is 0.8333 ms.)
3 The square- wave amplitude, frequency, pulse width, and duty cycle can
be set when the output is enabled (OUT) or disabled (SBY). Ensure that
the square- wave annunciator ( ) is flashing to edit the amplitude,
frequency, pulse width, and duty cycle values. (Press again if it is
not.)
