Agilent 33250A Generator

The Agilent 33250A is an 80 MHz integrated function/arbitrary waveform generator. It is designed to provide a versatile and reliable signal source for education, R&D, and maintenance applications, capable of generating a variety of standard waveforms and simple custom waveforms.

Key Features and Functions
Frequency Range:

Standard waveforms: 1 µHz to 80 MHz (sine wave, square wave).

Covers a wide range from ultra-low frequencies to high-frequency radio, meeting most basic to intermediate application needs.

Waveform Types:

Standard function waveforms: sine wave, square wave, triangle wave, ramp wave, noise (white noise).

Arbitrary waveforms: Built-in 14-bit, 64 kpts arbitrary waveform generator, capable of generating custom waveforms or using built-in special waveforms such as pulse, exponential rise/fall, and Sin(x)/x.

Modulation Functions:

Supports AM (amplitude modulation), FM (frequency modulation), FSK (frequency shift keying), and PWM (pulse width modulation).

Features linear/logarithmic sweep and burst functions.

Output Characteristics:

Output amplitude: Up to 10 Vpp (into 50 Ω), with 1 mVpp resolution.

Output impedance: 50 Ω (fixed).

These characteristics enable it to directly drive most circuit boards or test equipment.

Connectivity and Display:

Interfaces: Standard GPIB and RS-232 interfaces, with optional LAN interface. This was the standard configuration for that era.

Display: Backlit LCD screen for intuitive viewing of current configurations.

Main Application Areas
Due to its versatility, the 33250A is widely used in:

Circuit design and testing: Providing excitation signals for analog circuits such as amplifiers and filters.

Education and training: Used in university and vocational school electronics laboratories to teach fundamental concepts like waveforms and modulation.

Service and repair: Debugging and maintaining electronic equipment, such as audio devices and power supplies.

Sensor simulation and testing: Generating sensor signals to test data acquisition systems.
In summary, the Agilent 33250A is an excellent general-purpose signal source suitable for a wide range of daily testing tasks.
