• Remote Interface Operation :
VOLTage {<
amplitude
>|MINimum|MAXimum}
Or, you can set the amplitude by specifying a high level and low level
using the following commands.
VOLTage:HIGH {<
voltage
>|MINimum|MAXimum}
VOLTage:LOW {<
voltage
>|MINimum|MAXimum}
You can also use the
APPLy
command to select the function, frequency,
amplitude, and offset with a single command.
DC Offset Voltage
The default offset is 0 volts for all functions.
• Limits Due to Amplitude : The relationship between offset voltage and
output amplitude is shown below. The peak output voltage (DC plus
AC) cannot exceed the instrument output rating (±5 V into 50
 load,
or ±10 V into a high impedance load).
• 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).
|Voffset| < Vmax – Vpp/2
If the specified offset voltage is not valid, the waveform generator will
automatically adjust it to the maximum DC voltage allowed with the
amplitude specified.
• Limits Due to Output Termination : The offset limits are determined
by the current output termination setting. For example, if you set the
offset to 100 mVDC and then change the output termination from
50 ohms to high impedance, the offset voltage displayed on the
waveform generator’s front-panel will
double to 200 mVDC (and no
error will be generated). If you change from high impedance to
50 ohms, the displayed offset will drop in half.
See “Output
Termination” on page 101 for more information.
