AWG2021
Characteristics
Standard Waveshapes
Sine, square, triangle, ramp, pulse, arbitrary, linked sequence
and DC.
Arbitrary Waveforms
Execution Memory -
Waveform: 256 Kwords. Marker: 256 Kwords x 2-Bits.
Data Points of Waveform Size: 64 to 256 K in multiples of 8.
Real-time Sequencer Memory - 8 K individual waveforms.
Loop Counter: 1 to 65,535 repeats.
Burst Mode Counter: 1 to 64 K cycles.
Catalog Memory Clock
Frequency Range - 10 Hz to 250 MHz.
Resolution - 4 digit.
Accuracy - 50 ppm (+15°C to +30°C).
Skew between CH 1 and CH 2 (Opt. 02 only) - Within 4 ns.
Operating Modes
Continuous - Output continuous at programmed waveshape,
frequency, amplitude and offset.
Triggered - Output quiescent until triggered by an external,
GPIB or manual trigger; then generates a sequence only one
time.
Gated - Same as triggered mode except period is executed only
for the duration of the gated signal until the sequence started is
completed.
Burst - Output quiescent until triggered by an external, GPIB or
manual trigger; then generates "n" sequences or cycles.
Waveform Advance - Continuously generates the waveform in
a predefined sequence; the next trigger advances to the next
waveform in sequence.
Autostep - Generates the predefined waveform once in the
Autostep File; the next trigger advances the waveform.
