Arbitrary Waveform Generators
AWG520
Characteristics
Operating Modes
Continuous – Waveform is iteratively output. If a
sequence is defined, the sequence order and repeat
functions are applied.
Triggered – Waveform is output only once when
an external, internal GPIB/Ethernet or manual trig-
ger is received.
Gated – Waveform begins output when gate is true
and resets to beginning when false.
Enhanced – Waveform is output as defined by
the sequence.
Arbitrary Waveforms
Waveform Length – 256 to 4,194,048 points in
multiples of four.
Sequence Length – 1 to 8,000 steps. Both CH1
and CH2 operate from the same sequence.
Sequence Repeat Counter – 1 to 65,536 or
infinite.
