	A new measurement always uses the frequencies specified in the “Freq Hz” column, so you can also create your own frequency curves or use those from an existing measurement series. You can create a new table by clicking on ''Sweep New''. The number of measurement points (table rows) depends on the adjacent drop-down menu. You can achieve particularly fast, rather rough measurements with the ''Short'' setting, while the ''Fine'' selection produces a significantly finer frequency resolution. The table is generated algorithmically, but you can change (and save) individual values in the frequency table as you wish.

			With ''Test Generator Frequency'' of '''1024 Hz''', ''Measure external FX Loop'' '''checked''' (will bypass preamp/swell simulation), observed analog output level on main outputs should be about '''630mV RMS or -1.8dB'''. Observed output level on separate organ output is lower at '''170 mV RMS or -13dB'''. Both will '''not''' vary sigificantly with frequency changes as there is no swell simulation.

			With ''Test Generator Frequency'' of '''225 Hz''', ''Measure external FX Loop'' '''unchecked ''', observed output level on main outputs is about '''750mV RMS or -0.5dB'''. It will vary with frequency due to preamp simulation.

	Using the “EFX Input” effects loop input (HX3.7 only), it is also possible to measure external devices and the HX3 equalizer. If the “Measure External FX Loop” checkbox is active, the level detector is set to the HX3's effects loop input, and the test generator's unmodified signal appears at the organ output. The internal preamp simulation is ‘’'switched off'‘’, so the frequency response is completely linear.
