Pressing a hot key directly activates the Operating Zone and displays its associated settings submenu.
This allows jumping from one zone to another while in Monitor, Generator, or Duplex mode without
navigating back to the main screen. The hot keys activate the respective zones and submenu as follows:
RF Zone – Press numeric hot key 1
Audio Zone – Press numeric hot key 4
Display Zone – Press numeric hot key 2
Meter Zone – Press numeric hot key 5

Note: Hot keys are inactive whenever there is a data entry window open or the horizontal soft key menu
below the display is shown. Press the Esc key to close data entry windows or horizontal soft key menus
before using hot keys in Monitor, Generator, or Duplex mode.
2.2 Operating Instructions
The main operating modes of the R8100 are oriented towards testing 2-way radios and related
infrastructure. So for a majority of applications the R8100 will either receive or generate an RF carrier
and display carrier specific information such as power level, modulation content, spectral content, etc.
The description of R8100 operation will initially focus on basic use as a monitor and generator then expand
into more detail on associated functions.
2.2.1 RF Zone / Monitor Mode
The R8100 Monitor mode provides the analyzer's receiver function used for testing radio transmitters. It
is capable of monitoring over the air (OTA) RF signals through its ANTENNA port or with a direct
connection to the transmitter at the RF In/Out port. The operating frequency range is from 250 kHz to 3.0
GHz in 1 Hz increments with selectable bandwidths between 6.25 kHz and 200 kHz. The analyzer
processes AM and FM modulated carriers and a variety of audio encoding formats. Once set to an RF
carrier’s center frequency the R8100 accurately determines the frequency error, power level, and
modulation characteristics. These are shown at the bottom of the RF Zone section of the main display,
below the separator line – see Figure 3.2.1-1. Expanded versions of these measurements are also available
in the Bar Graphs selection in the Display Zone.
