I mean, 25OHM and 75OHM external resistors have "CURRENT LOOP" connected to the 454a host, but 125OHM does not.0:37 of

The ESU-2350 is really good, but it's too big unless it's been tested in the workshop, which is going to be tough for portable use,And I think BC manufacturers added 'DSP' signal processing, it doesn't matter for actual use.Typically, the actual testing of the ESU is done in one operation room before moving on to the next operation room. Portability is very important.
The power dissipation resistors inside the host take up a lot of volume, it would be revolutionary if only one resistor could meet all the needs。
Looks like an "Electronic Load Tester", I know it's not possible because of the high frequencies, it's just my imagination
