N7020A power-rail transient probing
Keysight Technologies · Warpage, topography and stress metrology
- Purpose
- Measure noise, ripple and load transients on accessible DC rails to compare waveforms and events.
- Technical approach
- A 1:1 active probe with DC offset connects small voltage variations to compatible scopes. N7020A has a stated 2 GHz bandwidth.
- Scope of use
- For accessible measurement points with a ground reference; check scope, software, accessories and operating range.
- Limitations and open questions
These evaluation considerations are compiled by BLNKK from public information. They are not supplier guarantees or a mandatory submission checklist.
Scope and limitations±24 V offset differs from ±850 mV active-signal range; 50 kΩ is DC impedance. Connections affect response, inaccessible rails remain inaccessible, and waveforms alone do not identify root causes.
What to prepareBLNKK suggests preparing voltage, expected swing, test points, grounding and load events; record scope, bandwidth and noise baseline to check connection effects.
Confirm with the supplierConfirm scope/software compatibility, accessory ratings, offset, grounding and calibration. Check licensing separately if additional power-analysis software is needed.
- Public evidence
- The product page lists PI/load-response uses and offset/signal ranges, without guaranteeing access to internal package rails.
