The instrument also generates triangle, noise, and DC waveforms, along with five built-in arbitrary shapes — exponential rise, exponential fall, negative ramp, Sin(x)/x, and cardiac — and supports user-defined arbitrary waveforms up to 64K points at 14-bit resolution and a 50 MSa/s sample rate. Function/arbitrary waveform generators in this class serve as the stimulus source in stimulus-response test setups across electronics design, education, production test, and general bench work. The 33220A's documented application set includes complex custom waveform generation through the IntuiLink Arbitrary Waveform software, which allows waveforms to be created, edited, and downloaded from a PC, or captured from an oscilloscope using IntuiLink for Oscilloscope and replayed through the generator. Up to four user-defined waveforms can be stored in non-volatile memory for recall without re-downloading. ## Brand Heritage The 33220A was originally manufactured under the Agilent Technologies brand. Agilent's electronic test and measurement business was spun off as Keysight Technologies in 2014, with Keysight continuing as the current corporate successor for instruments originating from this product line. ## Product Core & Specifications Category Specification Value Waveforms Standard Waveforms Sine, Square, Ramp, Triangle, Pulse, Noise, DC Built-in arbitrary Waveforms Exponential rise, Exponential fall, Negative ramp, Sin(x)/x, Cardiac Sine Sine Frequency Range 1 µHz to 20 MHz Sine Amplitude Flatness (< 100 kHz) 0.1 dB Sine Amplitude Flatness (100 kHz to 5 MHz) 0.15 dB Sine Amplitude Flatness (5 MHz to 20 MHz) 0.3 dB Sine Harmonic distortion, DC to 20 kHz \-70 dBc (< 1 VPP); -70 dBc (≥ 1 VPP) Sine Harmonic distortion, 20 kHz to 100 kHz \-65 dBc (< 1 VPP); -60 dBc (≥ 1 VPP) Sine Harmonic distortion, 100 kHz to 1 MHz \-50 dBc (< 1 VPP); -45 dBc (≥ 1 VPP) Sine Harmonic distortion, 1 MHz to 20 MHz \-40 dBc (< 1 VPP); -35 dBc (≥ 1 VPP) Sine Total harmonic distortion, DC to 20 kHz 0.04% Sine Spurious (non-harmonic), DC to 1 MHz \-70 dBc Sine Spurious (non-harmonic), 1 MHz to 20 MHz \-70 dBc + 6 dB/octave Sine Phase noise (10 kHz offset) \-115 dBc/Hz, typical Square Square Frequency range 1 µHz to 20 MHz Square Rise/Fall time < 13 ns Square Overshoot < 2% Square Variable duty cycle 20% to 80% (to 10 MHz); 40% to 60% (to 20 MHz) Square Asymmetry (@ 50% duty) 1% of period + 5 ns Square Jitter (RMS) 1 ns + 100 ppm of period Ramp, Triangle Ramp, Triangle Frequency range 1 µHz to 200 kHz Ramp, Triangle Linearity < 0.1% of peak output Ramp, Triangle Variable Symmetry 0.0% to 100.0% Pulse Pulse Frequency range 500 µHz to 5 MHz Pulse Pulse width (period ≤ 10s) 20 ns minimum, 10 ns resolution Pulse Variable edge time < 13 ns to 100 ns Pulse Overshoot < 2% Pulse Jitter (RMS) 300 ps + 0.1 ppm of period Noise Noise Bandwidth 10 MHz typical Arbitrary Arbitrary Frequency range 1 µHz to 6 MHz Arbitrary Waveform length 2 to 64 K points Arbitrary Amplitude resolution 14 bits (including sign) Arbitrary Sample rate 50 MSa/s Arbitrary Min.
