I use TD of the R&S ESU to prescan and manually take 6 highest data points. For the frequency range of 30MHz-1GHz, I setup trace at maximum hold, antenna height at 1m and 2 m, rotate turntable 360 degrees for each antenna height. Most of the QP final data is within 1 dB of the prescan PK data. The prescan takes about 5 minutes (maybe less). For frequency above 1GHz, instead of 2m, I set antenna at 1.5m.

I have done some experiments and found that the results with a TD scan are very close to the results with a regular scan. The TD scan reduces the test time by quite a bit. Does anyone know if the TD scan would be acceptable for preview measurements during a qualification test? The preview measurement is what takes the most time. The only other option is to do an EMI sweep (in S/A mode) but the frequency and amplitude are inaccurate. An accurate preview measurement is necessary so that the proper points can be selected for maximization and final measurement.
