manually scan an RF frequency segment for an unknown carrier, with the smooth action associated with
an analog control. The spin knob adjusts whichever digit is highlighted in the data entry field by the
Left/Right (◄►) cursor control buttons. Continuous rotation of the knob steps the frequency adjustment
by the smallest value of the highlighted digit. Moving the highlight to a different field allows coarse
(faster) or fine (slower) tuning as desired.
The tuning knob may be pressed at any time to Enter the
current value
The Up/Down (▲▼) keys provide precise step changes for final adjustment after the
R8100 is quickly dialed close to the desired frequency.
2.2.2 RF Zone / Generate Mode
The R8100 Generator mode is the analyzer's transmitter function used for testing radio receivers over a
frequency range of 250 kHz to 3.0 GHz in 1 Hz increments. The RF carrier output is accessible through
the RF Gen Out or RF In/Out ports for over the air (OTA) operation or direct coupling into a receiver.
The output level is adjustable from -95 dBm to +5 dBm on the RF Gen Out port, and -130 dBm to -30
dBm on the RF In/Out port. A variety of modulation types and encoding formats are available for the RF
carrier. Figure 3.2.2-1 shows the R8100 in the generate mode in the RF Zone section of the main display.

To enable the R8100 Generate mode press the Generate navigation button from within any menu and
confirm that “Generate” is indicated in the lower left corner of the R8100 main display. Then press the
Esc button repeatedly until the soft keys to the right of the display area indicate RF Zone, Audio Zone,
Display Zone, and Meter Zone. This places the R8100 at the entry point for adjusting basic Generate
mode settings such as frequency, modulation type etc.
Note: In Generate mode you can bypass standard
menu navigation and jump directly to a Zone and its settings submenu with the appropriate hot key – see
paragraph 3.1.2.
Output Level
Output Lvl (gray) displays the Generator RF output level. Volts, Watts, or dBm units may be selected
with the Output Level Units setting in the RF Zone submenu.
