10.2.1 Frequency Configuration (Fixed Frequency)
In single frequency measurement mode, the R&S FPC1000 determines the power
level of a single frequency only. You can measure any frequency supported by the
R&S FPC1000.
Defining the receiver frequency
1. Press the "Freq" key to open the frequency menu.
2. Select the "Frequency" menu item.
The R&S FPC1000 opens an input field to define the receiver frequency.
3. Enter the receiver frequency you want.
The frequency you have entered becomes the new receiver frequency. The
R&S
FPC1000 updates the bargraph accordingly.
You can also define the frequency by selecting a specific transmission channel. In
that case, the frequency is defined in a
channel table .
Defining a frequency step size
For a quick change of frequencies with the rotary knob, define a frequency step size.
1. Press the "Freq" key to open the frequency menu.
2. Select the "Frequency Step" menu item to open the frequency step menu.
3. Select one of step size options.
● "0.1 x RBW"
The step size equals 10 % of the resolution bandwidth.
● "= Center"
The step size equals the center frequency.
● "Manual <x> Hz"
Define any step size you want in the input field that opens when you select this
option.
The R&S FPC1000 adjusts the step size accordingly.
Using channel tables
For measurements on systems that use channels instead of single frequencies, you
can also load a channel table and measure the channel power.
1. Press the "Freq" key to open the frequency menu.
2. Select the "Frequency Mode" menu item.
3. Select the "Channel Downlink" or "Channel Uplink" menu item to select a channel
table.
Note that when you work with channel tables, you select the frequency in terms of
a channel. The channel defines the receiver frequency.
