In this setup, the 81180A is used as a 2-GHz IQ modulation
source. The Agilent E8267D performance signal generator
Option 016 is needed for the 2 GHz IQ modulation input.
You can use markers in conjunction with the pulse
modulation to suppress the signal in the pulse pauses. The
Generate versatile waveforms
An arbitrary waveform generator is ideal for generating
multiple waveform formats, so you can achieve
interoperability between terrestrial and space-based
communication devices.
In addition to the flexibility of an arbitrary waveform
generator, the 81180A gives you unprecedented flexibility
with respect to channels. The instrument is available
in 1- or 2-channel versions. The 2-channel version can

markers don’t reduce the number of bits, so using markers
improves waveform resolution instead of reducing it.
You can use the 81180A for generating direct RF signals up
to 1.5 GHz with a good signal waveform resolution.
run either in uncoupled mode so both channels work
independently or in coupled mode, either phase coherent
or with a defined delay between them. You can couple two
2-channel instruments to form a 4-channel instrument to
simulate multiple emitter or receivers, such as multiple
aircraft, where each could be designated as a target. By
synchronizing the channels, you simplify your test setup
and align the frequency and phase of the signals.
