FAQ #6: Why do I need the J2111A if I already have an electronic load?

Why do I need the J2111A if I already have an electronic load?


The J2111A is not the same as an electronic load.  In many cases, the use of an electronic load will interfere with the measurement results, either due to limited bandwidth or due to high capacitance of the load and internal dampers, necessary to stabilize the load.

The J2111A is designed to provide ony small signal currents, with very low capacitance and with high speed.  In most cases, we prefer that the system be the load and that the J2111A be used to make measurements in an operating system as this provides the most accurate results.

We are frequently asked for higher currents, and therefore do anticipate a high current version being available in the near future and will likely be designated as the J2112A.
