Keysight (Agilent) N6705A DC Power Analyzer, Modular, 600 W, 4 Slots

The Keysight N6705A DC Power Analyzer is a modular 600 W mainframe that integrates four DC power supply slots with integrated Digital Multimeter, oscilloscope, arbitrary waveform generator, and data logger functions. Accepts up to four N6700 family DC power modules - 23 options ranging from 50 W to 300 W with voltage ratings to 100 V and current ratings to 20 A. Delivers voltmeter accuracy to 0.016% + 1.5 mV and ammeter accuracy to 0.03% + 15 μA, both at 18-bit resolution.

The onboard oscilloscope digitizes voltage and current at up to 100 kHz with 512 kpts memory and 18-bit resolution. Arbitrary waveform generator operates to 4500 Hz with 300 W output capability. Data logger captures up to 500 million readings at intervals from 20 µs to 60 s, with 512 MB non-volatile storage for logs, traces, and settings.

Step voltage changes execute in 160 microseconds. Programmable via GPIB (SCPI-1993, IEEE 488.2), USB, and LAN with LXI Class C compliance. Operates 0°C to 55°C (current derated 1% per °C above 40°C), up to 95% relative humidity, and 2000 m altitude.

Accepts 100–240 VAC, 50/60/400 Hz input; 1440 VA consumption. Dimensions 194.7 × 425.6 × 313 mm; 16 kg. Note: N6705A is discontinued; N6705B is the compatible replacement.
