Multi-level Square Wave

Maximum of 16 steps of discrete amplitude (10 bit resolution) and duration (1 to 1024
samples). Allows generation of three-level square wave, staircase, multiplexed LCD
driver signals, etc.

Arbitrary

A number of frequently required waveforms are pre-programmed in the internal read-
only memory (ROM). Waveforms may also be downloaded via the RS232 or GPIB
interfaces and stored in the internal non-volatile random-access memory (RAM).

Hop

Up to 16 different waveforms can be output in sequence at a rate determined by either the
internal timer, an external trigger a remote command, or from the keyboard. Each
waveform can be set to any wave shape (except noise), frequency, amplitude and offset.
Frequency-only changes are phase-continuous.

Noise

White noise output with a typical -3 dB bandwidth of 0.03 Hz to 700 kHz. Amplitude and
offset are adjustable. Noise can only be used with gated and AM modes.

Modulation Modes

Continuous

Continuous cycles of the selected waveform are output at the programmed frequency.
