We are using the Radiated Emission Multiband test, to perform measurements in our anechoic chamber. During the measurement we are performing measurements at different antenna heights (1, 1.5, 2, 2.5, 3, 3.5 and 4 meters).
That is all working fine, and not a problem.

Is it however possible to use 'logarithmic' stepsize for the antenna height? We would like to use smallers steps in the lower part, and would like to use bigger steps in the higher part of the antenna tower (based on our experience we see that this also results in the same measurement results.
An ideal list of scan heights would be same thing like: 1, 1.2, 1.5, 1.9, 2.4, 3 and 4 metres.

It currently is not possible to configure a multiband test to perform measurements on specific antenna heights or with a logarithmic step.
With some tricks it is however possible to configure the multiband test to perform the measurements on only the specified heights.

1. Open a Multiband Radiated Emission test with a single band
2. Specify all parameters for the emission test as it is required by the standard
3. Select 1 m as the lowest antenna height and 1.2 m as the heighest antenna height, using 2 steps
4. Duplicate the created band
5. In the duplicated band, select 1.5 m as the lowest antenna height and 1.9 m as the heighest antenna height, using 2 steps
6. Duplicate the initial band
7. In the duplicated band, select 2.4 m as the lowest antenna height and 3 m as the heighest antenna height, using 2 steps
8. Duplicate the initial band
9. In the duplicated band, select 4 m as the lowest antenna height and 4 m as the heighest antenna height, using 1 step

This Multiband Radiated Emission test will perform the measurement on all the specified heights. This test is using 4 different bands, which all have the same frequency range. The result is however completely comparable to a Radiated Emission test with a single band which is measuring several antenna heights.
