155 WaveTek Arbitrary Waveform Generator
The 155 is an Arbitrary Waveform Generator from WaveTek. An arbitrary waveform generator (AWG) is a type of electronic test equipment people use to generate repetitive or single-shot electrical waveforms. Single-shot waveforms require a triggering source, either internal or external, while repetitive waveforms do not. Inject the signal the waveform generator creates into a device for analysis during testing, finding problems with the device, or confirming proper operation.
