Arbitrary Waveforms
Memory
Waveform: 1 Mwords x 8-Bits (4 Mwords x 8-Bits with Option 01).
Marker: 1 Mwords x 2-Bits (4 Mwords x 2-Bits with Option 01).
Data Points of Waveform: 32 to 1 M ( 4 M with Option 01) in multiples of 32.
Clock Generator
Frequency Range: 1.000000 kHz to 1.024000 GHz.
Resolution: 7 digits.
Stability: 1 ppm/year (+15 to ± 25 degrees C).
Operating Modes
Continuous: Output waveform/sequence continuous at programmed waveshape, frequency, amplitude, and offset.
Triggered: Output quiescent until triggered by an external, GPIB, or manual trigger; generates a waveform/sequence only one time.
Burst: Output quiescent until triggered by an external, GPIB, or manual trigger; then generates a waveform/sequence up to 65,536 times.
Gated: Same as continuous mode except period is executed only for the duration of the gated signal until the sequence started is completed.
Waveform Advance: Output quiescent until triggered by an external, GPIB, or manual trigger, then generates the waveform/sequence in the Sequence file. When the scan count reaches value, output stops and waits for next trigger.
Auto Step: Continuously outputs the waveform/sequence in the Auto Step file; the next Auto Step Trigger (rear panel) advances the waveform/sequence.
Slave: Receives clock from a master arbitrary waveform generator for parallel operation.
