Adjust waveform parameters
When you turn on your instrument, the default output signal is a 1 kHz sine
waveform with an amplitude of 1 V
p-p
. In the following example, you can change
the frequency and amplitude of the original output signal.
1.
To change frequency,
press
Freq/Period
. Press
it again to choose
Period
.
The parameter which is
chosen will be lighted with
white background. Use the
general purpose knob to
set frequency value
directly, and use the
/ direction button
to move the cursor.
2.
Or push the numeric
panel button, and an
input box will pop up.
Input frequency value
and choose proper unit.
Use
BK/SP panel
button to delete
character if input error
occurs.
3.
Press
NextPage
to go
to the next page for
other unit options.
4.
Press
Cancel
to cancel
the operation.
NOTE:
You can change
the Period, Ampl,
High, Offset, and Low
values in the same way.
