The 154 Programmable Waveform Generator is a precision source of sine, square, and triangle waveforms covering a frequency range from 0.001Hz to 10MHz. In addition, a calibrated, programmable DC voltage output is also provided. Operating modes of continuous, trigger, or gated mode, selectable. Amplitude, frequency, and DC level may be digitally programmed with three digit resolution. All programming is DTL/TTL compatible.
