P25 Base Option
Introduction
The 3900 Series P25 Options provide users with the ability to test the operational capabilities of P25
Conventional and P25 Trunked radio systems. P25 Option 390XOPT200 is the basis from which all
other P25 Test Options are developed and is referred to in this manual as the P25 Base Option. This
option is required to operate all other P25 options.
This chapter provides an operational description of the P25 Base Option. Refer to Chapter 3, P25
Trunking Option and Chapter 4, Miscellaneous P25 Options for information on other P25 options.
Optional Fields
P25 display tiles contain some fields that are only available when specific P25 options are installed
in the Test Set. Optional fields and parameters are noted as *option enabled.

RF Control Tile
The RF Control Tile configures the Test Set for evaluating P25 mobile radios operating in
Conventional Mode and for testing the physical layer of P25 radio systems. RF Control Tile fields
must be configured according to the operating parameters of the Unit Under Test (UUT) to obtain
valid test data.
Fig. 2-2 P25 RF Control Tile - Phase 1 Protocol Selected
Transmit Field Definitions
1/2 Channel Toggle Buttons
The 1 / 2 Channel Toggle Buttons enable/disable a Channel to be used for the transmit or receive
path. Channel 1 and 2 can be enabled at the same time, however, the secondary channel
frequency must be within +/- 2.5 MHz of the primary channel frequency. Channel 2 is *option
enabled when the P25 Trunking Option is installed in the Test Set.
Pri (Primary Channel)
Selects the channel as the primary frequency.
S0/S1 (Slot 0/Slot 1) Toggle Buttons
The S0 and S1 toggle buttons are *option enabled when the X2-TDMA® Base Station and
Parametric Option is installed in the Test Set.
When X2-TDMA®Protocol is selected, the Test Set allows the user to select the pattern
transmitted on Slot 0 and Slot 1. The S0 and S1 buttons enable/disable these Slots. S0 and/or
S1 must be enabled to generate an X2-TDMA signal.
Freq (Frequency)
Defines carrier frequency of signal generated by the Test Set.
Level
Defines the output power level of Transmit signal.
Units (Level)
The Units drop-downmenu selects the unit of measurement for the Power Level.

P25 Base Option
Subject to Export Control, see Cover Page for details.
2-3
Protocol
Selects the P25 Protocol of the signal generated by the Test Set. The P25 Base Option currently
supports P25 Phase 1 (non-trunked) and Analog Protocols. Other protocols are *option enabled
(i.e., SNSZ).
Modulation
This drop-down menu selects the Modulation type of the signal generated by the Test Set. Plot/
graph traces vary based on the selected Modulation type. The Modulation types available depend
on the Protocol type selected and the options installed in the Test Set.
Pattern
The Pattern drop-down menu selects the data or voice pattern to be generated by the Test Set.
P25 patterns are derived from TIA-102.CAAA Specification. Pattern types include standard and
non-standard P25 patterns, stored speech files and voice modulation. Available pattern types are
dependent on the type of Protocol selected and the options installed in the Test Set.

Receive Field Definitions
1/2 Channel Toggle Buttons
The 1 / 2 Channel Toggle Buttons enable/disable a Channel to be used for the transmit or receive
path. Channel 1 and 2 can be enabled at the same time, however, the secondary channel
frequency must be within +/- 2.5 MHz of the primary channel frequency. Channel 2 is *option
enabled when the P25 Trunking Option is installed in the Test Set.
Pri (Primary Channel)
Selects the channel as the primary frequency.Selects the channel as the primary frequency.
Spk (Speaker)
Selects the channel that routes incoming audio signal to Test Set demodulators.
Freq (Frequency)
This field defines the receiver frequency. For accurate readings, this frequency should be set to
the UUT transmit frequency.

P25 Base Option
Subject to Export Control, see Cover Page for details.
2-4
Offset
The Offset field displays or defines the offset between the Transmit and Receiver frequencies.
When set to LOCK, changing the Receive or Transmit Frequency offsets the other frequency by
the value specified in the Offset field. For example, setting the Receiver frequency to 150 MHz,
with an offset of 2.5 MHz, results in the Transmit frequency updating to 152.5 MHz. Or, if the
Transmit frequency is set to 150.0 MHz, with an Offset of 2.5 MHz, the Receive frequency
updates to 147.5 MHz.
When set to UNLOCK, a value can be entered independently for either the Transmit Frequency or
the Receiver Frequency.
Protocol
Selects the expected P25 Protocol of the received signal.
Modulation
The 3900 Receiver Modulation type in the P25 Base Option is system defined as C4FM and can
not be changed by the user.
IF Bandwidth
The BW drop-down menu selects the receiver bandwidth. 12.5 kHz is the typical bandwidth used
on P25 systems. 25 kHz bandwidth is useful when a mobile radio is transmitting off frequency.

Slot 0/1 (Receive)
The Slot 0/1 toggle button is *option enabled when the X2-TDMA® Base Station and Parametric
Option is installed in the Test Set.
Selecting X2TDMA Protocol enables the Receiver Slot which routes the Audio for the selected
Slot (0 or 1) to the speaker.

(150 kHz). When a Mod Index value is entered, the Deviation value updates to display the value
in kHz. For example, when the Mod Index value is set to 100%, the Deviation value updates to
150 kHz, the maximum Deviation setting.
