• Arbitrary Waveform Limitations: For arbitrary waveforms, the
maximum offset and amplitude will be limited if the waveform data
points do not span the full range of the output DAC (Digital-to-Analog
Converter). For example, the built-in "Sinc" waveform does not use
the full range of values between ±1 and therefore its maximum offset
is limited to 4.95 volts (into 50 ohms).
• You can also set the offset by specifying a high level and low level.
For example, if you set the high level to +2 volts and the low level to
-3 volts, the resulting amplitude is 5 Vpp (with an offset voltage of
-500 mV).
• For dc volts, the output level is actually controlled by setting the
offset voltage. You can set the dc level to any value between ±5 Vdc
into 50 ohms or ±10 Vdc into an open circuit.
To select dc volts from the front panel, press
DC On softkey. Press the Offset softkey to set the desired offset
voltage level.
• Front-Panel Operation: To set the dc offset, press the Offset softkey
for the selected function. Then use the knob or numeric keypad to
enter the desired offset. To set the offset using a high level and low
level, press the Offset softkey again to toggle to the HiLevel and
LoLevel softkeys.
• Remote Interface Operation:
VOLTage:OFFSet {<offset>|MINimum|MAXimum}
Or, you can set the offset 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.
