Product Description
The M64700G25 Mobile Radio works within a frequency range of 794-806 MHz and requires a 1/4-wavelength
antenna.
The IPSeries High Speed Mobile Radios are intelligent devices designed for the challenging requirements
of mobile data applications. Mounted in vehicles, other intelligent devices may connect to the serial or
Ethernet ports for connectivity back to the Internet Protocol Network Controller (IPNC) and other such
servers. It provides the mobile link to land-based wired networks. The high speed mobile radio circuit
boards are built using surface mount technology (SMT) and through-hole components.
Figure 1: IPSeries High Speed Mobile Radio (Front View)
Product Functionality
The high speed mobile radio utilizes a high-performance, 32-level QAM. Further it uses state-of-the-art
OFDM technique. This new technique will enable the high speed mobile radio to transmit and receive
more than 100 Kbps data in a 25 kHz band. The high speed mobile radio features low power
consumption, high performance integrated GPS receiver. Embedding this technology in the mobile radio
lowers the cost of acquiring GPS data from vehicles and ensures optimal performance.
The high speed mobile radio technology includes Diversity Reception (DR) capability. DR reduces the
effects of fades in a multi-path environment. With the use of two (2) antennas mounted at a calculated
distance on the roof of the vehicle the Diversity Reception System (DRS) minimizes the effects of fading
by intelligently selecting the receiver with a better signal.
Diversity is most effective when the vehicle is in motion.

Step 8 At the desktop, click on the Start button and select Programs and MS-DOS
Prompt. The MS-DOS window displays.
Step 9 Ping the IPNC commanding the transmitter to send 25 messages of 500
characters each to the IPNC as well as a response through Receiver 1 back to
the laptop or desktop PC by typing in the following command at the MS-DOS
prompt replacing NNN.NNN.NNN.NNN with the IPNC IP address:
Ping NNN.NNN.NNN.NNN –n 25 –l 500 –w 4000
After entering the command, press [ENTER] to continue.
When entering a command, pay special attention to the spaces and the
characters being typed.
# If the calibrated base station does not respond, check the syntax of the Ping command and verify
the IP address is correct.
If the ping command runs but high packet loss figures are shown, perform the following:
1. Verify that the calibrated base station and mobile radio antennas are separated by at least
10 feet. If the antennas are too close, the mobile radio receivers overload by the
transmitters resulting in intermittent communication and high data errors.
2. Verify the calibrated base station parameters are correct for the mobile radio. Such
parameters include IP addresses and complementary RX/TX frequencies.
3. Check to ensure the data and power cables are connected correctly.
4. If the Ping command continues to fail, test using a mobile radio that is known to be working
properly.
Step 10 Check the test laptop and verify that the Packets Lost Percentage is zero to 1%
packet loss. Greater losses may indicate a problem with the transmitter/receiver
1, or modem circuitry.
Step 11 Change the antenna on the mobile radio to the RX2 antenna input.
Step 12 Connect the RF attenuator to the mobile radio’s TX/RX1 antenna input.
Step 13 Connect the second antenna to the RF attenuator. In the IPMessage window,
enter receiver=2. This will allow the mobile radio to only receive via Receiver 2.
Step 14 Type the following command at the MS-DOS prompt replacing
NNN.NNN.NNN.NNN with the IPNC IP address:
Ping NNN.NNN.NNN.NNN –n 25 –l 500 –w 4000
After entering the command, press [ENTER] to continue.
Step 15 Check the test laptop and verify that the Packets Lost Percentage is zero to 1%
packet loss. Greater losses may indicate a problem with the transmitter/receiver
1, or modem circuitry.

M64700G25-FCCRpt.doc Page 27
Adjustment / Alignment Procedures
Receiver Injection
Perform the following steps to adjust the receiver injection and injection frequency:
Step 1 While monitoring the receiver injection frequency at RXINJ1, input the value for the DAC
frequency control for minimum frequency error (+/- 100Hz). Record this value on the Test
Data Sheet.
Step 2 While monitoring the 44.545 MHz 2nd injection frequency at U6 pin 4, adjust trimmer
capacitor CV22 for the maximum amplitude of this injection frequency. The maximum
amplitude must be between -3 to -5 dBm. Record this value on the Test Data Sheet.
Step 3 Repeat Step 2 by monitoring U9 pin 4 and adjusting CV20 for Receiver2 IFLO. Record this
value on the Test Data Sheet.
Receiver 1
Perform the following steps to adjust receiver 1:
Step1 Inject an on-frequency carrier signal with amplitude of -80 dBm, modulated with a 1 kHz test
tone at +/- 5.0 kHz deviation into receiver 1's antenna port.
Step 2 While monitoring the voltage at RSSI1 Test Point with a DMM, adjust trimmer capacitor CV15
and C16 to midway between the points where the oscillation stops.
Step 3 While monitoring the DC level of the recovered modulation; adjust potentiometer RV6 for a
reading of 2.500 VDC +/- 1 mV DC.
Step 4 While monitoring the amplitude of the recovered audio signal, adjust potentiometer RV5 and
RV6 for a reading of 350 mV RMS and 2.500 VDC.
Step 5 Steps 3 and 4 are interactive adjustments, therefore repeat steps 3 and 4 until further
adjustment is no longer required (i.e. when 350 mV RMS and 2.500 VDC are realized).
Step 6 While monitoring the recovered audio signal at TP1, verify the distortion is less than 3%
adjust CV15 and CV16 if necessary to achieve less than 3% distortion. Record this value on
the Test Data Sheet.
Step 7 While monitoring the recovered audio signal at TP1, verify the SINAD is -118 dBm or better.
Record this value on the Test Data Sheet.
Receiver 2
Perform the following steps to adjust receiver 2:
Step 1 Inject an on-frequency carrier signal with amplitude of -80 dBm, modulated with a 1 kHz test
tone at +/- 5.0 kHz deviation into Receiver 2's antenna port.
Step 2 While monitoring the voltage at RSSI2 Test Point with a DMM, adjust trimmer capacitor CV6
and CV7 to midway between the points where the oscillation stops.
SECTION 4: FACTORY TEST PROCEDURE
M64700G25-FCCRpt.doc Page 28
Step 3 While monitoring the DC level of the recovered modulation, adjust potentiometer RV4 for a
reading of 350 mV (+/-10 mV) RMS.
Step 4 While monitoring the amplitude of the recovered audio signal, adjust potentiometer RV3 for a
reading of 2.500 (+/-10 mV) VDC.
Step 5 Steps 3 and 4 are interactive adjustments, therefore repeat steps 3 and 4 until further
adjustment is no longer required (i.e. when 350 mV RMS and 2.500 VDC are realized).
Step 6 While monitoring the recovered audio signal at TP1, verify the distortion is less than 3%,
adjust CV3 if necessary to achieve less than 3% distortion. Record this value on the Test
Data Sheet.
Step 7 While monitoring the recovered audio signal at TP1, verify the SINAD is -118 dBm or better.
Record this value on the Test Data Sheet.
Transmit Data
Perform the following steps to adjust transmit data:
Step 1 Use IPMessage to set the transmit power to 0.
Step 2 Using the x=1400,n command of IPMessage to generate transmit data messages while
observing the transmitted signal on the HP RF communications test set, adjust pot R33 for
minimum frequency error while transmitting data messages.
Step 3 Turn potentiometer RV1 fully counterclockwise.
Step 4 Adjust RV2 for deviation of 4.9 kHz.
Step 5 Using calibrated base station, and monitoring the uplink received data quality on the base
station's Hyperterminal screen, slowly turn RV1 clockwise until consistent data quality
readings of 240 - 248 are achieved using 1400 character test messages. Data quality
reading should not be less than 240 for 1400 character messages.
If unable to reach the data quality readings then ask for Technical Support. Poor data
quality readings are indicative of poor group delay performance, or other defect.
Step 6 Verify transmit deviation, frequency error, and transmitting data messages quality and record
this data on the Test Data Sheet.
Power Setting
Perform the following steps to adjust the transmit power control:
Step 1 Attach a power attenuator to the transmit port of the radio.
Step 2 Using the x=1400,n command of IPMessage, and while monitoring the transmit power level
on the HP communications test set, check the level of the transmit power. Using IPMessage
set the power setting to txpower=0. The radio should have an output power level of
approximately 1 mW. Record this value on the Test Data Sheet.
SECTION 4: FACTORY TEST PROCEDURE
M64700G25-FCCRpt.doc Page 29
Step 3 Using IPMessage send the txpower= command to increase the power level settings until 30
Watts of output power is obtained. Record this value on the Test Data Sheet. Note that
values on the table are to plot the codes vs. power output. The 30-Watt setting can be a
code not on the table. Adjust txpower until the code is found that does not exceed 30.0
Watts. Record this value on the Test Data Sheet.
Do not to exceed 30 Watts of output power, as this may reduce the life of the amplifier.
Receive Data
Perform the following steps to verify the receive data performance:
Step 1 Using the DOS ping command on the PC connected to the radio, ping the network controller
to generate uplink and downlink data messages. The following command will generate one
Hundred 500 character messages:
>;Ping 192.168.3.3 -n 100 -l 500
Step 2 Observe the data quality readings on the IPMessage window of the PC connected to the
radio using the V (for Verbose) command in the IPMessage program. With the mobile radio's
antenna connected to receiver 1, verify the received data quality readings are consistently
248s. Data quality readings should also be verified at the base station using the V command
on the Hyperterminal window.
Step 3 Verify receiver 2 data quality readings are also consistently 240 to 248s by changing the
antenna from receiver 1 port to receiver 2 port. In this manner both uplink and downlink data
quality can be verified. Record this data on the Test Data Sheet.
Final Test
A final test must be performed prior to shipping the M64700G25 mobile radio to the customer. This final
test will verify that the timing characteristics are correct and that both transmit and receive data quality
readings are consistently high.
Perform the following steps for the final test:
Step 1 Attach the 40dB 100-Watt power attenuator to the transmit port of the radio.
Step 2 Program the radio for full power operation. The tx power level setting can be found in the
radio's Test Data Sheet.
The setting must not to exceed 40 Watts.
Step 3 Attach a digital scope to the base station as described in section the next section, Uplink
Hardware Timing Verification. Using the x=1400,19 command (which will cause the radio
to transmit 19, 1400 character messages), verify the following:
Transmit frequency of radio is adjusted for minimum frequency error of +/- 100 Hz.
SECTION 4: FACTORY TEST PROCEDURE
M64700G25-FCCRpt.doc Page 30
The x=1400,19 command will generate different messages with differing DC components.
Each message will slightly slew the frequency off from the center frequency). Be careful to
closely monitor the variation in transmit frequency due to these different messages and
ensure that on average the transit frequency error has been minimized to within +/-100 Hz.
This indicates that some of these test messages will be slightly high in frequency, some
messages will be slightly low in frequency, and some messages will be right on frequency.
Step 4 Verify the transmit deviation is 4.9 kHz
Step 5 Verify the timing characteristics are identical to the plots in the next section, Uplink
Hardware Timing Verification.
Step 6 At the base station monitor PC, verify that all the data quality readings are 240 and higher.
Step 7 Move the scope probes to monitor the timing at the mobile radio as described in Downlink
Hardware Timing Verification. Generate test messages by issuing a ping command to the
IPNC from the PC attached to the radio. The following command will cause 100 pings, 500
bytes in length to be transmitted from the mobile radio and echoed by the IPNC through the
base station:
.>;Ping 192.168.3.3 -n 100 -l 500 -w 2000
Step 8 Set CRC =1 Enable on the radio
Step 9 Verify the timing characteristics are identical to those in Downlink Hardware Timing
Verification.
Step 10 Verify that both receivers on the mobile radio report data quality readings of 240 or higher
(248 is typical). This can be accomplished by installing the antenna on the TX/RX1 port and
verifying RX1 is selected by observing the RX1 LED on the mobile radio and installing the
antenna on the RX2 port and verifying RX2 is selected by observing the RX2 LED on the
mobile radio.
Step 11 Reset CRC = 0 Disable on the radio
Step 12 In IPMessage, type the ? command to radio. Copy the radio settings and paste them into the
Test Data File.
Step 13 Perform a close visual inspection of the radio closely inspecting manufacturing related
problems (loose screws, solder particles, etc.).
SECTION 4: FACTORY TEST PROCEDURE
M64700G25-FCCRpt.doc Page 31
Uplink Hardware Timing Verification
The figure below displays an oscilloscope plot of an uplink data message from the mobile to the base
station. Channel 1 is connected to the base station's RSSI (XXX-12), channel 2 is connected to the base
station's recovered modulation, and channel 3 is connected to the base station's modem chip select line.
The scopes acquisition mode is high-resolution.
As seen in the above plot, the mobile radio's transmit carrier has ramped up to full power (channel 1) in
just a few milliseconds. The recovered modulation (channel 2) is stable by this time. There follows a few
milliseconds of quiet time followed by 12 milliseconds of symbol sync time.
The recovered modulation from a mobile radio should look identical to this plot. The recovered
modulation signal should be approximately 1.0 Volts peak-to-peak and should be centered at
approximately 2.5 VDC as is indicated in the figure above.
SECTION 4: FACTORY TEST PROCEDURE
M64700G25-FCCRpt.doc Page 32
The figure below displays another oscilloscope plot of an up-link data message from the mobile to the
base station. As in the last plot, channel 1 is connected to the base station's RSSI (J5-12), channel 2 is
connected to the base station's recovered modulation test point, and channel 3 is connected to the base
station's modem chip select line (U16-13). The scope's acquisition mode is now in the peak detect mode.
This enables the base station's modem CS (Chip Select) line to be viewed.
The base station's microcontroller, upon detecting a step response in the RSSI (caused by the mobile
radio's transmitter coming up to power), waits a period of time equal to the programmed value of the base
station's carrier detect delay time. The microcontroller then instructs the modem to search for the modem
synchronization preamble. When the base station instructs the modem to look for sync tones, the
modem's CS line transitions low. This can be seen in the above plot. Approximately 10 milliseconds after
the mobile radio's transmitter causes a step increase in the base station's RSSI, the CS signal goes low
momentarily. As can be seen, the sync tones are stable by this time and the modem quickly establishes
synchronization.
SECTION 4: FACTORY TEST PROCEDURE
M64700G25-FCCRpt.doc Page 33
Downlink Hardware Timing Verification
The figure below displays a plot of the downlink timing characteristics. Channel 1 is connected to RSSI,
channel 2 is connected to recovered audio, and channel 3 is connected to the modem CS pin. The scope
is in the high-resolution acquisition mode.
There is a very short period of quiet time (no modulation) followed by approximately 12 milliseconds of
modem synchronization time (sync time).
SECTION 4: FACTORY TEST PROCEDURE
M64700G25-FCCRpt.doc Page 34
The plot shown in the figure below is the same as before but now the scope is in the peak detect
acquisition mode. After the mobile radio detects a step response in the RSSI (caused by a down-link
transmission), the radio's microcontroller waits an amount of time equal to the programmed value of the
"carrier detect delay time" then instructs the modem to look for frame sync. When the microcontroller
instructs the modem to look for frame sync, it asserts the modem's CS line (active low). In this plot, the
modem's CS line can be seen to transition low approximately 3 milliseconds after the base station's
transmitter has come up to full power.
The recovered modulation should be centered at approximately 2.5 VDC and should have an amplitude
of approximately 800 mV peal-to-peak as indicated in the plot above.
