Replacing the Keysight 6060B
300 W-class programmable electronic load.
What happened to it
The product page remains but is marked obsolete. An installed base still needs a migration path.
The substitution that goes wrong
Minimum operating voltage is the specification that most often ends a drop-in replacement. Older loads pulled current down to lower voltages than many current models will.
Specifications to match
- Power, voltage and current at your actual operating point, not the corner
- Minimum operating voltage — the classic mismatch when replacing older loads
- GPIB/SCPI command usage in existing test code
- Rack space and cooling, since modern equivalents differ in form factor
Before you swap the hardware
A replacement that matches on headline power can still fail on the details that keep an existing rack working.
- 01Confirm power, voltage and current envelope at your operating point.
- 02Check minimum operating voltage — the AN236 publishes 1.8V at rated current, which is the number that usually goes unchecked.
- 03Audit GPIB/SCPI command usage in existing test code.
Where Intepro fits
The closest current equivalent is the AN236 Series High-Power DC Electronic Load, manufactured by Ainuo and supplied and integrated by Intepro. Every figure below is transcribed from its datasheet and re-checked against that document on each build.
| Power range | 2kW - 60kW per unit |
|---|---|
| Output voltage | 0-150V DC, 0-600V DC or 0-1200V DC by class |
| Output current | 0-80A to 0-2400A by model (load input/sink rating) |
| Part numbers | AN23602E-150-200 · AN23603E-150-300 · AN23604E-150-400 · AN23605E-150-500 · AN23606E-150-600 · AN23608E-150-800 · AN23610E-150-1000 · AN23612E-150-1200 · +46 more |
Manufactured by Ainuo and supplied by Intepro. The 150V class was transcribed from the AN23600F user manual; the 600V and 1200V classes from the AN236(F) datasheet Intepro publishes, read from the rendered pages because that PDF carries no text layer. The manufacturer prints that specification changes will not be notified separately — confirm against the current datasheet before quoting.
Where this one stops
The AN236 is a standalone instrument. If your 6060B lived in a mainframe alongside other modules and your software addresses it through that mainframe, there is no mainframe here and the integration work is real. Budget for it rather than discovering it. On the upside, minimum operating voltage is published — 1.8V at rated current — so the check that usually needs a phone call is a line-item comparison.
