Using the APPLy Command
4
APPLy Command Syntax
• Because of the use of optional parameters in the APPLy commands
(enclosed in square brackets), you must specify frequency to use the
amplitude parameter, and you must specify both frequency and
amplitude to use the offset parameter. For example, the following
command string is valid (frequency and amplitude are specified but
offset is omitted and therefore uses a default value).
APPL:SIN 5.0E+3, 3.0
However, you cannot specify an amplitude or offset without specifying
a frequency.
• You can substitute “MINimum”, “MAXimum”, or “DEFault” in place
of specific values for the frequency, amplitude, and offset parameters.
For example, the following statement outputs a 3 Vpp sine wave at
80 MHz (the maximum frequency for sine) with a -2.5 volt offset.
APPL:SIN MAX, 3.0, -2.5
•The APPLy command performs the following operations:
• Sets the trigger source to Immediate (equivalent to sending the
TRIG:SOUR IMM command).
• Turns off any modulation, sweep, or burst mode currently enabled
and places the instrument in the continuous waveform mode.
• Turns on the Output connector (OUTP ON command) but does not
change the output termination setting (OUTP:LOAD command).
•
Overrides the voltage autorange setting
and automatically enables
autoranging
(
VOLT:RANG:AUTO
command
).
• For square waveforms, overrides the current duty cycle setting
and automatically selects 50% (FUNC:SQU:DCYC command).
• For ramp waveforms, overrides the current symmetry setting and
automatically selects 100% (FUNC:RAMP:SYMM command).
