Using The Instrument 3-3

To calculate the maximum offset available for a particular amplitude
setting, use the following inequality:

Tip: If the desired amplitude/Offset setting cannot be obtained using
Standard Waveforms, try generating it as an Arbitrary Waveform
using WaveCAD.
/* Turn the main output on.*/
:OUTPut ON;
/*Turn the SYNC output on, if required.*/
:OUTPut:SYNC ON;
If the above commands are executed correctly, a square waveform
will be seen on your oscilloscope.
Using the APPLy
Command
The APPLy command provides a high level method of programming
the synthesizer. Selection can be made for function, frequency,
amplitude, offset and other parameters which are associated with
the selected function. For example, the following statement outputs
a 2 Vp-p square wave at 1 MHz with a 0 V offset and 10% duty
cycle using APPLy:
APPL:SQU 1E6, 2, 0, 10
It is not necessary to enter every parameter with the APPLy
command. If only the frequency and offset need to be changed,
omit the other parameters while keeping the commas. The other
parameters will be set to the power-up default values:
APPL:SQU 10E6,,1
