elects the standard square wave as
the active function, and simultaneously
sets the frequency to 10.7
MHz
(10.7e6), amplitude to 2
V, offset to
1 V, and duty cycle to 30%.
outp 1 Turns on the output.
The above is an example of a full
utilization of the Apply command,
including the frequency, amplitude, offset, and duty cycle
parameters for a standard square wave. You may use the Apply
command in a similar manner for other standard or arbitrary
waveforms.
You may use the Apply command o
n a partial set of the available
parameters of a waveform. To leave out a parameter, place no
characters between the corresponding comma separators. For
example, you may specify the frequency and duty cycle of a square
wave while leaving the amplitude and
offset at the default values,
as follows:
*rst Restores factory defaults.
appl:squ 12.7e6,,,45 Selects
the standard square wave as
the active function, and simultaneously
sets the frequency to 12.7 MHz, leaves
the amplitude at the default value,
leaves off
set at the default value, and
sets the duty cycle to 45%.
outp 1 Turns on the output.
In a similar manner, you may use the Apply command with other
standard waveforms to set some parameters while leaving others at
their default values.

Waveforms
Before the 3152B can generate arbitrary waveforms
, you must first
download them to its waveform memory.
This section describes the
arbitrary waveform function and explains how to down
load
waveforms.
