The Agilent 33220A function and arbitrary waveform generator is an upgraded version of the 33120A. It is capable of producing all of the following waveforms: sine, squar, ramp, triangle, pulse, noise, and Dc. It can also generate arbitrary waveforms such as exponential rise/fall, negative ramp, sin(x)/x, and cardiac. The following are standard waveform characteristics. Sine waveforms have a frequency range from 1 micro-hertz to 20 MHz, with an average amplitude flatness within 0.18 dB. Total harmonic distortion from DC to 20 kHz is 0.04%. At frequencies from DC to 1 MHz, spurious signals occur at -70dBc, while at frequencies from 1 to 20 MHz, spurious signals occur at -70 dBc + 6 dB/octave. There is typically -115 dBc/Hz phase noise (10 kHz offset). For square waves, frequencies can range between 1 micro-hertz and 20 MHz, having rise and fall times under 13 ns, with less than 2% overshoot. Square waves can have variable duty cycles from 20 to 80% to frequencies up to 10 MHz. Above 10 MHz up to 20 MHz, duty cycle can be set from 40 to 60%. Jitter is at 1 ns + 100 ppm of the period. For ramp and triangle waveforms, frequency can range from 1 micro-hertz to 200 kHz. These forms are linear to within <0.1% of the peak output, with variable symmetry of 0.0 to 100.0%. Pulse waves can have frequencies from 500 micro-hertz to 5 MHz. The pulse width, for periods <= 10 s, can be a minimum of 20 ns, with a 10 ns resolution. Variable edge time can range from <13 ns to 100 ns. Pulse overshoot is under 2%, and jitter is at 300 ps + 0.1 ppm of the period. The noise output has a bandwidth of 10 MHz. The output power can range from 10 mVpp to 10 Vpp into 50 ohms, or 20 mVpp to 20 Vpp into an open circuit. Level settings are accurate to +/-1% +/- 1 mVpp. Level readings can be expressed in Vpp, Vrms, and dBm. Amplitude can be displayed with 4 digits of resolution. DC offset has a range of +/- 5 V into 50 ohms, or +/- 10 V into an open circuit. DC offset settings are accurate to +/-2% of offset setting, or +/-0.5% of amplitude +/_ 2 mV. DC offset can be displayed with 4 digits of resolution. Available modulation includes AM, FM, PM, PWM, FSK, and external modulation. AM can be applied to carrier waveforms of sine, square, ramp, and arbitrary using both an internal and external sources. Internal AM can handle sine, square, ramp, triangle, noise and arbitrary. AM depth can range from 0.0 to 120.0%. FM can be applied to sine, square, ramp, and arbitrary carrier forms, both from internal and external sources. Internal FM covers sine, square, ramp, triangle, noise, and arbitrary waveforms. FM deviation ranges from DC to 10 MHz. Phase modulation can be applied to carrier waveforms of sine, square, ramp, and arbitrary, from both internal and external sources. Internal PM covers sine, square, ramp, triangle, noise, and arbitrary waveforms. PM deviation ranges from 0.0 to 360.0 degrees. PWM applies to only to the pulse waveform type, from both internal and external sources. PWM deviation can range from 0 to 100% of the pulse width. For FSK, carrier waveforms include sine, square, ramp, and arbitrary from both internal and external sources. Bandwidth ranges from DC to 20 kHz. The Agilent 33220A is capable of sweeps using sine, square, ramp, and arbitrary waveforms. Sweeps can be either linear or logarithmic, including both up and down directions. Sweep time can range from 1 ms to 500 s. Sweeps can have single, internal, or external triggers. Burst operation can be applied to sine, square, ramp, triangle, pulse, noise and arbitrary waveforms. Burst mode operation can run in counted mode (1 to 50,000 cycles), infinite, or gated modes. The burst start/stop phase can range from -360 to 360 degrees. The internal burst period can range from 1 micro-second to 500 s. Gating is provided by the external trigger, while triggering can be either single, internal or external.
