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.
