Output Configuration
present at the instrument's output depends on the load connected to the instrument. See OUTPut[1|2]:LOAD for
details.
l Arbitrary Waveform Limitations: For arbitrary waveforms, amplitude is 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, so its maximum amplitude is limited to 6.087 Vpp (into 50 Ω).
l Setting the high and low levels also sets the waveform amplitude and offset. For example, if you set the high level
to +2 V and the low level to -3 V, the resulting amplitude is 5 Vpp, with a -500 mV offset.
l To output a DC voltage level, select the DC voltage function (FUNCtion DC) and then set the offset voltage (VOLT-
age:OFFSet). Valid values are between ±5 VDC into 50 Ω or ±10 VDC into an open circuit. While the instrument is
in DC mode, setting amplitude has no effect.
l Front Panel:
l SCPI:
[SOURce[1|2]:]VOLTage:OFFSet {<offset>|MIN|MAX}
[SOURce[1|2]:]VOLTage:HIGH {<voltage>|MIN|MAX}
[SOURce[1|2]:]VOLTage:LOW {<voltage>|MIN|MAX}
The APPLy command configures a waveform with one command.
Output Units
Applies to output amplitude only.
l Output units: Vpp (default), Vrms, or dBm.
l Setting is volatile.
l Units selection applies to front panel and remote interface operations. For example, if you select "VRMS" remotely,
the units are displayed as "VRMS" on front panel.
l Amplitude units cannot be dBm if output termination set to high impedance. Calculating dBm requires finite load
impedance. In this case, units are converted to Vpp.
l You can convert between units. For example, to convert 2 Vpp to Vrms equivalent:
The converted value is 707.1 mVrms for a sine wave.
