The HP 3563A and 3562A are dual-channel dynamic signal analyzers designed for measurement and analysis of analog signals, with the HP 3563A extending capability to digital signals and devices as well. Both instruments cover a measurement range from 64 µHz to 100 kHz on both channels in single- or dual-channel operation, with 80 dB dynamic range and full alias protection. The HP 3563A is positioned as a control systems analyzer for engineers working with electrical, mechanical, or electromechanical loops, while the HP 3562A is well suited for test and analysis of mechanical systems and predominantly analog electrical and electromechanical systems.

According to the datasheet, the HP 3563A supports network analysis of digital or analog devices through accurate, high-resolution frequency response measurements of mechanical and analog, digital, or mixed analog/digital electronic systems. Measurements can be performed with linear resolution FFT, logarithmic resolution FFT, or swept-sine analysis. The instruments also support online analysis of distortion, drift, modulation, and phase noise, and can analyze transient events in both the time and frequency domain or capture time records for later recall and analysis. The HP 3563A adds extraction of system models with s- and z-domain curve fitting and modeling of systems using frequency response synthesis.

Brand Heritage

Hewlett-Packard's test and measurement business was spun out as Agilent Technologies in 1999, and that electronic measurement business became Keysight Technologies in 2014. Instruments originally branded HP — including the HP 3563A and HP 3562A dynamic signal analyzers — trace their support and successor lineage through that path. The HP signal analyzer family from this era remains in active use in legacy control-systems test setups and mechanical-vibration laboratories where the original test procedures reference these instruments by name.

Compare Other Models in This Series

The HP 3563A and HP 3562A are companion dynamic signal analyzers from Hewlett-Packard sharing a common dual-channel FFT-based architecture, 64 µHz to 100 kHz measurement range, 80 dB dynamic range, and front-panel analog source. The datasheet describes the HP 3563A as a compatible superset of the popular HP 3562A, with the FFT-based design offering the versatility required for spectrum, network, and waveform measurements across both instruments.

The most significant difference between the two instruments, as stated in the datasheet, is that the HP 3562A cannot be used to measure and analyze digital signals and devices. The HP 3563A adds 16-bit digital input capability (TTL or CMOS), a digital signal source, mixed analog/digital frequency response measurement, and additional analog source waveforms (step, pulse, ramp, and arbitrary).

Confirm the specific configuration, included accessories, and current calibration status on the individual product listing for the unit you are evaluating.

Within this family, the HP 3563A is positioned as the control systems analyzer for next-generation systems involving electrical, mechanical, or electromechanical loops, including mixed analog and digital inputs and outputs. It is the model to specify when digital signal acceptance, digital source output, or s- and z-domain curve fitting for system modeling is required.

The HP 3563A and HP 3562A differ primarily in digital capability, source waveform set, and the inclusion of curve-fitting and frequency-response-synthesis tools on the HP 3563A. The HP 3562A handles mechanical systems and predominantly analog electrical and electromechanical systems; the HP 3563A handles those plus digital signals and devices and mixed analog/digital systems.

See the comparison table that follows for the specific differences as printed in the datasheet — digital input acceptance, digital source availability, analog source waveform set, and curve-fitting capability are the primary differentiators between the two models in this family.
