Output Level
Output Level (white) adjusts the RF level of the transmitted carrier for the active output port. Range is
from -95 dBm to +5 dBm on the RF Gen Out port, and -130 dBm to -30 dBm on the RF In/Out port. When
Modulation Type is AM, the upper limits are -1 dBm and -36 dBm respectively.
Gen Port
Choose the active port (RF In/Out or Gen Out) for the R8100 carrier output in a selection table using the
Up/Down (▲▼) keys or spin knob.
Note: If RF Level Offset is enabled, the Gen Port label is cyan-colored indicating that Output Level
amplitudes are adjusted by the Gen Port-specific offset. See section
2.2.8.2 for details.
Bandwidth
Sets the maximum occupied bandwidth in kHz for the R8100’s carrier via a set of horizontal soft keys.
The range is from 6.25 kHz (narrow) to 200 kHz (wide).
Output Level Units
Selects the measurement units for setting the Generator RF output level via horizontal soft keys. Choices
are Volts, Watts, or dBm, and the level is displayed in the Output Level field in the RF Zone display
window.
2.2.3 RF Zone / Duplex Mode
The R8100 Duplex mode provides simultaneous generator and monitor operation for testing radio
transceivers with full duplex capability, or radio systems with offset transmit and receive frequencies. All
RF parameters of the R8100 generator and monitor are independently adjustable during Duplex operation
except the shared functions of modulation type and bandwidth. Duplex mode provides offset frequency
operation of the generator and monitor over the full frequency range of the R8100. Figure 3.2.3-1 shows
Duplex operation of the R8100 in the RF Zone section of the main display.
Note: If RF Level Offset is enabled, the Gen Port and Mon Port labels are cyan-colored indicating that
Output Level amplitudes and RX measurements are adjusted by the Gen Port and Mon Port-specific
offsets. See section
2.2.8.2 for details.
