3 Features and Functions
72 Keysight 33210A User’s Guide
– You can set the output amplitude in Vpp, Vrms, or dBm. For more information,
see “Output Units” on page 75.
– You cannot specify the output amplitude in dBm if the output termination is
currently set to “high impedance”. The units are automatically converted to
Vpp. For more information, see “Output Units” on page 75.
– Arbitrary Waveform Limitations: For arbitrary waveforms, the maximum
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 amplitude is limited to 6.087 Vpp (into 50 ohms).
– While changing amplitude, you may notice a momentary disruption in the
output waveform at certain voltages due to switching of the output
attenuators. To prevent this disruption in the output, you can disable the
voltage autoranging feature as described on page 79.
– You can also set the amplitude (with an associated offset voltage)
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. See “DC Offset Voltage” on the following page for
more information.
To select dc volts from the front panel, press and then select the DC On
softkey. Press the Offset softkey to set the desired offset voltage level.
– Front-Panel Operation:
To set the output amplitude, press the
Ampl
softkey for
the selected function. Then use the knob or numeric keypad to enter the
desired amplitude. To set the amplitude using a high level and low level, press
the Ampl softkey again to toggle to the HiLevel and LoLevel softkeys.
