Selecting the Standard
If you need to perform measurements that are conform to a telecommunications stan-
dard, you can activate one of the predefined standards that are already stored in the
R&S Spectrum Rider memory. However, you can create new configurations to perform
measurements on other standards as well.
1. Press the [MEAS] key.
2. Select the "Standard" softkey.
The R&S Spectrum Rider opens a file manager dialog box to select the Standard.
3. Select one of the available standards.
The R&S Spectrum Rider loads the configuration of the selected standard. It auto-
matically sets the optimal span, resolution bandwidth, video bandwidth, sweep time
and detector for the standard.
You can create and edit standards with the R&S InstrumentView software and transfer
them to the R&S Spectrum Rider via the USB or the LAN interface. The number of
standards the R&S Spectrum Rider can store in its memory depends on the number of
other data sets stored on the R&S Spectrum Rider.

Setting the Reference Level
The reference level is the power level that the R&S Spectrum Rider expects at the RF
input. When selecting the reference level, make sure that you do not overload the R&S
Spectrum Rider by applying a signal whose power exceeds the maximum reference
level.
As the power is measured with a small resolution bandwidth compared to the signal
bandwidth, it is still possible to overload the R&S Spectrum Rider, even if the trace is
within the measurement diagram. To prevent an overload, perform the measurement
with the largest resolution bandwidth possible using the peak detector. If you set these
parameters, it is not possible for the trace to exceed the reference level.
To simplify operation and to prevent incorrect measurements, the R&S Spectrum Rider
has an automatic routine for setting the reference level.
1. Press the [MEAS] key.
2. Select the "Level Adjust" softkey.
The R&S Spectrum Rider performs a measurement to determine the optimal refer-
ence level.
