Keysight (Agilent) 3245A 0 – 1MHz, Func Generators & Waveform Synthesizers

The Keysight (Agilent) 3245A is a dual-function universal source combining precision DC output with synthesized AC waveform generation up to 1 MHz. This instrument delivers 24-bit resolution in high-resolution DC mode, 60-ppm accuracy over 90 days, and supports arbitrary waveform synthesis with full 1 MHz bandwidth. Phase-continuous frequency changes enable dynamic testing without signal interruption, while selectable output impedance (0 Ω or 50 Ω) accommodates varied load requirements. Non-volatile storage preserves 14 instrument setups for instant recall. Electronic calibration eliminates downtime. BASIC-like programming constructs and downloadable subroutines enable standalone operation with minimal host interaction, making the 3245A suitable for benchtop evaluation or integration into automated test systems within a compact 3.5-inch rack footprint.
