David, My experience with TILE and industrial RF immunity and emission over four years has been: -
1. TILE speed seems limited by instrumentation here, not PC speed 2. Have kept immunity limit margins slack (albeit entirely above the required level). Very few retries at levelling are then required - makes a big difference to overall test time. The risk of slight overtest is no bad thing. 3. I know my HP 438A power meter is slow by modern standards. I'd swap that out if immunity test speed were an issue here. I did however reduce the measurement time in the 'Probes' tab in 'Immunity Test' to the workable minimum - trial and error working down from a longish time. 4. Our HP 8542E receiver has to take as long as it takes to meet bandwidth requirements for the tests - probably no different with any more modern receiver. Sounds like our applications may be different if you're working with 'really fast instruments with very short instrument delay times'. A little more detail might help someone else suggest more speed-ups.
