(OEM/Integrators Installation Manual)
Product Overview
AB1602 is a low-power, single-chip Bluetooth Low
Energy Single mode controller. It integrates a
low-power physical layer, a link controller with a
security engine. It supports the standard HCI
interface which is able to connect to different
MCUs for varies applications. The SPI and UART
interface are used for connecting to external host
MCU and the Bluetooth profiles are implemented
on the host MCU as well.

Introduction
The Airoha AB1602 Family Lab Test Tool provides a quick-and-easy test suite for Airoha AB1602 devices.
Three basic functions including TX, RX and Crystal Trim are included in this utility. User may use this tool
to perform continuous TX, Burst TX, RX BER and Crystal Clock Trimming to test Airoha AB1602 Family
products.
1.1 Supported Chips
The Airoha AB1602 Family Lab Test Tool supports AB1602.

Environment Setup
2.1
Hardware Setup
An UART interface is used for PC-to-DUT connection. User may also use an USB-to-UART adaptor at PC
side and then connect to DUT side. A reference connection diagram is shown in figure 2-1.

If an USB-to-UART adaptor made by Airoha is used (as in Figure 2-2), the J1 connector (to DUT) pin
definition is shown in Figure 2-3. The VCC selection on JP12 should be set to +3.3V (with a jumper).

Software Setup
If the AIROHA USB-to-UART adaptor board is used, the driver should be installed at first
(PL2303_Prolific_DriverInstaller_v110.exe). When the driver is installed and the board is connected to PC,
an USB-to-Serial COM port would be presented in the device manager as in figure 2-4.

Power-on the DUT, and press the connection button of the device to enter discoverable mode.
Select corresponding COM port number of DUT in the COM Select region of the Lab Test Tool, and
will be shown in the output window, as in figure 3-2 and figure 3-3.

If the success message is not shown, please check if the DUT is correctly powered up, the link between
DUT and PC is correctly connected, and the DUT is in discover
again.

Test Functions
TX Test
There are three modes supported in the TX Test functions, i.e. Single-tone TX, Continuous TX and Burst
TX.
AB1600_V0.3
Single Tone Transmission
When CTX_START is selected, a continuous single-tone signal without any modulation (i.e. Carrier Only)
will be sent out at RF port. User may first set different RF frequency and TX power setting on the
from 2402 to 2480, and Tx GC ranges from 16 to 63.
To save the current Tx GC setting, click the Write to EEPROM button.
Figure 4-1 Single tone transmission setting of Tx Tab
Continuous Data Transmission
When CTX_DATA is selected, a continuous modulated signal will be sent out at RF port. User may
first set different RF frequency, TX power setting, and choose modulation type with data format on the
from 2402 to 2480, and Tx GC ranges from 16 to 63. The data format supports all 0, all 1, 1010, and PN.
GFSK, 1/4pi-DQPSK, and D8PSK are supported for the modulation type.
To save the current Tx GC setting, click the Write to EEPROM button.

Burst Data Transmission
When BTX_PACKET is selected, a burst-type modulated signal will be sent out at RF port. User may
select a RF frequency for transmit. Then set TX GC value, packet type (DH1, DH3, DH5, 2-DH1, 2-DH3,
2-DH5, 3-DH1, 3-DH3 and 3-DH5 are supported) and Data type (all 0, all 1, 1010, 11110000 and PN) and
To save the current Tx GC setting, click the Write to EEPROM button.

This function is enabled by sending continuous fixed channel BTx command. You could set the sending
stop it.

RX Test
Two RX modes, continuous receiving and burst receiving, are supported in the RX Test function. The
former is used for CE/FCC tests, and the later is used for bit error rate (BER) calculation.
Continuous Data Receiving

Burst Data Receiving

receiving. In order to measure BER, a signal generator is required to generate Bluetooth standard packets
and transmitted to the DUT. The associated settings of the signal generator must be set as follows,
BD address = 0x006BC6967E
LT_ADDR = 7
Payload data = PN9 with initial seed = 0x01FF
If the transmitted data of signal generator is successfully received and decoded by DUT, a group of
BER test results will be shown in the output window including: (as in figure 4-6)

Crystal Trim
When a 16MHz crystal is used on the DUT, user may adjust cap value to fine tune the output
tuned
cap value into EEPROM. Whenever DUT is powered on, the parameters in EEPROM will be read out and
write into DUT, thus the output 16MHz reference clock frequency could be set to the trimmed value.
The crystal trimming can be performed either by a spectrum analyzer or a frequency counter. The
method is described below,
Figure 4-9
Crystal Trim function
When a spectrum analyzer is used:
-tone RF signal at 2441MHz. Using spectrum
analyzer to measure the frequency of the tone at RF output port, and then fine-tune the cap
value until the carrier frequency offset is less than (2.4 G * n ppm) Hz. (n ppm is the reference
clock accuracy spec of the Bluetooth specifications)
When a frequency counter is used:
Measure the clock with a frequency counter, and then fine-tune the cap value until the
reference clock frequency offset is less than (16 M * n PPM) Hz. (n ppm is the reference clock
accuracy spec of the Bluetooth specifications)

Test Mode
AB1500 supports entering test mode by UART.
