Agilent / Keysight DSOS054A High-Definition Oscilloscope: 500 MHz, 4 Analog Channels

The Keysight DSOS054A is a high-definition oscilloscope delivering 500 MHz bandwidth across 4 analog channels with superior signal fidelity for advanced electronic testing. The instrument combines a 10-bit ADC with a low-noise front-end architecture to achieve 8.1 bits average ENOB at full bandwidth, supported by 100 fs rms intrinsic jitter and 90 µV noise at 1 mV/div. Vertical resolution extends to 16 bits in high-resolution mode - four times the resolution of traditional 8-bit designs.

The 20 GSa/s maximum sample rate (10 GSa/s in 4-channel mode) and up to 800 Mpts memory depth enable deep signal capture and detailed waveform analysis. A 15-inch XGA capacitive touch display with multi-touch gesture support, Intel i5 quad-core processor, and 8 GB RAM create an integrated analysis platform. Dual video outputs, six USB ports (including 2 USB 3.0), gigabit Ethernet, and auxiliary trigger/reference outputs support flexible integration into production and development environments.
