Using The Apply Command; Table 3-2, Amplitude And Offset Ranges - Racal Instruments 3151 User Manual

3151 And 3151A User Manual
Using the APPLy
Command
There are three offset windows ("8 V, "800 mV, "80 mV); the
window selected is a function of the amplitude setting. Table 3.2
shows the maximum offset available within each window.
Amplitude
$1.6 V
$160 mV
$10 mV

Table 3-2, Amplitude and Offset Ranges

To calculate the maximum offset available for a partiular amplitude
setting, use the following inequality:
V
* V
+
amplitude
offset
2
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.
The APPLy command provides a high level method of programming
the generator. 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:
Window
