NOTE 

Do not apply input power to the GEN output 
port. In the event RF power is inadvertently 
applied, the port is protected by in-line RF fuse.  
This fuse may be accessed by unscrewing the 
front of the BNC connector out of the front panel. 

22-2  PROJ 25 CONV RADIO TRANSMIT 
 

TESTS (Monitor Mode) 

This section describes the basic test setup for 
testing Project 25 radio transmitted voice and 
embedded data. 

NOTE 

If the selected radio channel is encrypted, select 
the analyzer encryption algorithm and key as 
described in Section 21-7. 

1.   Place the cursor in the RF Zone and configure 

the analyzer in Monitor mode as shown in the 
example below: 

 

2.  Select the desired frequency that matches the 

radio under test; 806.0625 MHz is used in this 
example. 

3.   Connect the RF input/output of the radio under 

test to the RF I/O port of the analyzer as shown 
in Figure 21-4.  

4.   Press  the 

AUD

 hardkey to place the cursor in 

the Audio Zone and select 

VOICE FRAME

. 

 

5.   Press  the 

DISP

 hardkey to place the cursor in 

the Display Zone. 

NOTE 

If the radio transmit frequency is unknown, it can 
be determined by turning on the radio, pressing 
the radio PTT and placing the analyzer in RF 
Scan mode.  Refer to Section 21-7.1.2 under the 
General Operation tab for a description of the 
RF Scan function. 

 

Place the cursor in the “Meter:” Field and select 

RF DISPLAY

.  The monitored frequency, 

deviation, frequency error and input power level 
are all displayed in the Display Zone. 

22-2.1  PROJ 25 CONV Voice 

To display the voice analog waveform move the 
cursor to the “Display:” field in the Display Zone 
and select 

CLEAR SCOPE

.  Press the radio PTT, 

speak into the radio microphone, and turn up the 
volume on the analyzer.  If the radio is operating, 
the transmitted voice will be heard from the speaker 
of the analyzer. 

22-2.2  PROJ 25 CONV Voice Frame Embedded 
 Data 

To display the voice frame embedded data, move 
the cursor to the “Display:” field in the Display 
Zone and select 

VOICE FRAME

.  The Voice 

Frame decode table will be displayed as shown in 
Figure 21-19.  Press the 

decode start

 softkey then 

press the PTT on the radio to display the embedded 
data.  As each frame is captured, the number 
displayed in the “Frame Counter:” field will be 
incremented.  Press the 

decode stop

 softkey to 

discontinue capturing frames.
