In the default state, the reference level corresponds to the level at the right of the
bargraph. A triangle in the bargraph scale indicates the position of the reference
level.
If necessary, you can move the reference position to another position on the scale.
4. Select the "Range / Ref Position" menu item to open the corresponding menu.
5. Select the "Ref Position <x>" menu item.
6. Move the position of the reference level on the bargraph scale to another position.
The range is from 0 to 10. "0" corresponds to the left side of the bargraph, "10" cor-
responds to right side of the bargraph.
You can also select the level range that the bargraph covers. In the default state,
the bargraph covers 100 values of the unit you have selected (e.g. 100 dBμV).
7. Select the "Range <x>" menu item.
8. Define the level range you need.
Tip:
Auto range. When you select the "Auto Range" menu item, the R&S
FPC1000
automatically adjusts the range of the bargraph based on the currently applied sig-
nal strength.
10.4 Bandwidth Configuration
Access
: "BW"
Access
: "Setup" > "Config Overview" > "Bandwidth" (selected settings)
Remote commands to configure the bandwidth:
●
The receiver application adds 6
dB resolution bandwidths to the 3
already available in other applications. The 6
dB bandwidths are special band-
widths that are necessary for measurements according to CISPR16.
The R&S
FPC1000 provides an automatic bandwidth selection for CISPR bandwidths.
When you select the bandwidth automatically, the R&S
FPC1000 selects an appropri-
ate CISPR bandwidth, depending on the receiver frequency.
●
Frequencies < 150 kHz: 200 Hz CISPR bandwidth
●
Frequencies from 150 kHz to 30 MHz: 9 kHz CISPR bandwidth
●
Frequencies from 30 MHz to 1 GHz: 120 kHz CISPR bandwidth
●
Frequencies > 1 GHz: 1 MHz CISPR bandwidth
Selecting the bandwidth
1. Press the "BW" key to open the bandwidth menu.
2. Select one of the menu items.
● "RBW: Manual": Selects a 3 dB bandwidth.
● "CISPR BW: Manual": Selects a 6 dB bandwidth.
