Agilent/Keysight 3245A

The Agilent/Keysight 3245A is a universal source instrument combining precision DC voltage and current sourcing with advanced function and arbitrary waveform generation. It delivers 24-bit resolution in high-precision modes, selectable output impedance (0 Ω or 50 Ω), and floating outputs for flexible test configurations. The instrument supports sine, square, triangle, ramp, and arbitrary waveforms across a 0 Hz to 1 MHz frequency range, with 0.001 Hz resolution and 50 ppm accuracy.

DC outputs achieve 60 ppm 90-day accuracy, while AC amplitude accuracy reaches 0.35% of output + 0.41% of range. Phase-continuous frequency changes and non-volatile storage for up to 14 setups enable dynamic signal generation without interruption. GPIB and RS-232 interfaces support remote programming and embedded BASIC-like control routines for standalone operation.
