Description
The Keysight N7973A is a 2 kW dynamic DC power supply in the N7900 series of the Advanced Power System family, rated for 60 V and 33.3 A. Compared with the N6900 models, N7900 units add standard features for dynamic testing, such as voltage and current arbitrary waveforms and enhanced measurement with seamless ranging, which help characterize how a device draws power. It is typically used in ATE and design validation where a supply must both deliver power and record current profiles.
Key features
- 60 V, 33.3 A output in a 2 kW, 2U chassis
- Built-in voltage and current arbitrary waveform generation
- Advanced measurement with seamless ranging for capturing device current profiles
- Power, peak power, amp-hour and watt-hour measurement
- Two-quadrant operation with N7909A power dissipater; paralleling up to 10 kW
- GPIB, USB and LAN (LXI) interfaces
Typical applications
- Dynamic power testing of 48 V class devices
- Power profile capture during design validation
- ATE for telecom and industrial electronics
- Simulating supply transients and dropouts
