Remote Interface Operation
FREQuency <frequency>
You can also use the APPLy command to select the function,
frequency, amplitude, and offset.
Output Amplitude
The default amplitude is 1 Vpp (into 50
Ω
) for all functions.
Offset Voltage Limitations
The relation between the output amplitude and offset voltage
is shown below. Vmax is the maximum peak voltage for the
selected output termination (5 V for a 50 Ω load or 10 V for
a high-impedance load).
Limits Due to Output Termination
If you change the output termination setting, the value of
the output amplitude will be adjusted (and no error will be
generated).
For example, if you set the amplitude to 5 Vpp and then
change the output termination from 50 Ω to “high
impedance”, the amplitude value will double to 10 Vpp. If
you change from “high impedance” to 50 Ω, the displayed
amplitude value will drop to half. For more information, see
“Output Termination” on page 36.
