Keysight Technologies 3325B Options:
- 3325B - 001 - High Stability Frequency Reference
- 3325B - 002 - High Voltage Output
- 3325B - H05 - Internal MATE Programming
The Keysight (Agilent) 3325B Synthesized Function Generator delivers high frequency accuracy, resolution, and signal stability across DC to 21 MHz (sine), making it ideal for crystal filter tests, timing simulations, audio systems, and video system analysis. It produces precise sine, square, triangle, positive/negative ramps, arbitrary waveforms, and programmable DC offsets up to ±5V. Its microhertz-level resolution and excellent waveform linearity support VCO testing and process control applications.
With a built-in programmable modulation source, the 3325B supports internal or external AM/FM modulation. Sweep capabilities include linear, logarithmic, and discrete step modes, with sync outputs up to 60 MHz for integration into complex test setups.
Testwall can supply the used Keysight (Agilent) 3325B, fully tested. With expert support and global delivery, Testwall ensures high-performance instrumentation with unmatched reliability and service quality.
