Generating Continuous Signals

Select SINE on the function keys, if it is not already
selected.
If there is no signal at the oscilloscope input it will almost
certainly be because the generator's output is switched off.
If the lamp next to the MAIN OUT socket is not lit, press
the OUTPUT key. The AUX OUT socket is always on.
Press the right FIELD key to put the cursor in the numeric
part of the top line and move the cursor a couple of digits
to the right with the right DIGIT key. You can experiment
with the rotary control to adjust the frequency setting.
You can also experiment with entering frequencies using
the numeric keypad, and with using the DIGIT key to
adjust the frequency in decades; to do this, put the cursor
under the rightmost (units) field.
Set a frequency, for example 12.5 kHz
You can do this by either of the methods above.
The easiest is probably to key
FREQ/PER, 1, 2, ., 5, kHz, ENTER.
12
The display should look like this:
FREQ=12.50000kHz
VhiZ=+20.0 Vpp
DC=+0.00mV (+0.00mV)
SYM=50.0% (50.0%)
You can also view and edit in terms of period.
Move the cursor into the first field and press one of the
DIGIT keys.
The display should change to:
PER =80.00000us
VhiZ=+20.0 Vpp
DC=+0.00mV (+0.00mV)
SYM=50.0% (50.0%)
