After you have turned on the isotropic antenna, the R&S Spectrum Rider uses the
isotropic antenna for all measurements.
Note:
When you turn on the isotropic antenna without selecting a transducer factor,
the R&S Spectrum Rider displays the file manager dialog to select a transducer
factor. When the isotropic antenna is turn off, the transducer factor is unloaded.
Using transducer factors
The isotropic antenna is like a transducer. It has a characteristic frequency response
and it is necessary to correct the measurement results by these characteristics.
The transducer factors (
*.isotrd
) for each of the supported isotropic antennas are
provided with the R&S Spectrum Rider. The factors contain typical correction values for
all three antenna elements and the correction values for the cable.
1. Press [AMPT] key.
2. Select "Transducer" softkey.
3. Select the "Select Primary" menu item.
The R&S Spectrum Rider opens a file manager dialog box to select the transducer
factor.
4. Select the transducer factor you need.
The R&S Spectrum Rider shows the name of the active transducer on the display
(e.g. "Pri Tran TSEMF-B2_typical" ).
If you are using the extension cable (R&S TS-EMFZ2, order number: 1166.5708.04) ,
you have to take this into account as a secondary transducer.
1. Press [AMPT] key.
2. Select "Transducer" softkey.
3. Select the "Select Secondary" menu item.
The R&S Spectrum Rider opens a file manager dialog box to select the transducer
factor with the unit dB.
4. Select the transducer factor for the extension cable.
The R&S Spectrum Rider shows the name of the active transducer on the display
(e.g. "Sec Tran TSEMFZ2" ).
Chapter 6.4, "Using Transducer Factors"
You can create and edit transducer factor with the R&S InstrumentView software pack-
age and then transfer them into the internal memory of the R&S Spectrum Rider. Each
transducer factor can consist of up to 1000 reference values.
Display of the antenna directions
An isotropic antenna consists of three orthogonal elements. Each of these elements
measures the field strength from a different direction (x-, y- and z-axis).
