I don't know this specific load, but the fact that the meter range switch doesn't have any provision for "reflected" may well indicate that this unit is not measuring power using a directional couple
This load looks very similar to units that I came across in the 80's when working for the Swedish military. If it corresponds to this general type, it is a peak reading termination wattmeter intended
Steve, I was thinking it more than likely was measuring the RF voltage on the load instead of a caloriometer. I have a 1.5 kW meter/load here from B&W that does that. They then just rectify the RF wi
Karl-Arne, If it were, it would be ok as this would become a neet project to convert over to say a 1-1.5 kW load that was air cooled. Say maybe with a 1 minute max rating or so. Then by changing it t
The time such a load, when rated for pulsed waveforms, holds up for CW loads in the kW range is in the order of a few seconds, at the most. Many of these loads contain thin-film resistors which are v
In free air, the rating should be about 100 W, and in oil, depending on the design of the oil container maybe 800 - 1000 W. If the oil container is designed so there is a convection flow, the rating
