Figure 6-15: Transducer factors displayed
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 may consist of up to 1000 reference values.
For more information on transducer factors, see
Chapter 4.8, "Managing Datasets"
Interpolation between the values is performed with the aid of a modified spline algo-
rithm. Even if only relatively few values such as maxima, minima and turning points are
available, this algorithm can easily simulate the correction factors of common transduc-
ers. Two transducers can be switched on at a time. The second transducer must be
assigned the unit dB. The R&S Spectrum Rider adds the two transducers to a total
transducer.
Units supported for transducer factors:
●
dB
●
dB
µ
V/m
●
dB
µ
A/m
●
W/m2
The unit dB does not change the unit set on the R&S Spectrum Rider. It can be used,
for instance, to compensate for frequency-dependent loss and gain at the input of the
R&S Spectrum Rider. The units dBμV/m and dBμA/m convert the output power of an
antenna into electric or magnetic field strength. The unit W/m2 is used to calculate and
display the power flux density.
For example, to compensate for the cable loss between the transducer and the RF
input, the R&S Spectrum Rider can use two transducers at the same time. One of them
must have the unit dB, however, i.e. it must correspond to one loss or gain value.
1. Press [AMPT] key.
2. Select "Transducer" softkey.
Transducer factor availability
Transducer factors are not available for measurements with the tracking generator or
the Power Sensors. The "Transducer" softkey is therefore inactive.
