Arbitrary Waveforms
Execution Memory
- Waveform: 64 k (65,535) for each channel. Marker: 64 k for each channel.
Waveform Size: 16 to 64 k in multiples of 16.
Real-time Sequence
Memory - 8 k individual waveforms.
Loop Counter - Waveform:
1 to 64 k repeats. Sequence: 1 to 64 k repeats.
Catalog Memory
- 2 MB.
Catalog Memory Clock
Frequency Range - 0.01 Hz
to 20 MHz.
Resolution - Standard: 4 digits. With Option 05:
7 digits.
Accuracy - Standard: 50 ppm (+15 °C to +30 °C). Option
05: 5 ppm (+15 °C to +30 °C).
Operating Modes
Continuous
- Output waveform/sequence continuous at programmed parameters.
Triggered
- Output quiescent until triggered by an external, GPIB, or manual trigger;
generates a waveform/sequence only one time.
Gated - Same as
continuous mode except period is executed only for the duration of the gated
signal until the sequence is completed.
Seq/Wfm Advance - Continuous:
Continuously outputs the waveform/sequence in the Sequence file. The next
trigger advances to the next waveform/sequence. Master/Slave Operation.
Step
- Output quiescent until triggered; then execute the next waveform/sequence
in the Sequence file. When the loop count reaches its value, output stops
and waits for next trigger.
Auto Step - Continuous: Continuously
outputs the waveform/sequence in the Auto Step file. Step: Output quiescent
until triggered.
Master - Provides Point Rate Clock and Trigger
to a slave arbitrary waveform generator for phase synchronous parallel operation.
Slave
- Receives Clock and Trigger from a system clock for parallel operation.
