General Information on RF Troubleshooting

Notes:
Several bills of material (BOM): There are two different kinds of VCOs, VCTXOs, RF-PAs, SAW-fil­ters and Antenna Switches (ASM) assembled. They may only be replaced with the same type as the original component (from the same manufacturer).
Phoenix version: In this document there are example measurements being depicted with pictures of AMS-Phoenix, version A 2004.06.1.69. In later versions pictures of menus and windows may look dif­ferently.
Layout version: The drawings of test points and component placement in this version of the document are taken from build B4.0 layout (1cna_41). If you use the document for newer layout versions, make sure to use the corresponding assembly and test point drawings.

Test environment

It is assumed, that the phones are disassembled and tested with a repair jig MJ-22R.
The following measurements have to be done for repairing the phone boards:
RF measurements shall be done using a spectrum analyzer together with a high­frequency probe. Note that the signal will be significantly attenuated. Correct attenuation can be checked using a “good” phone board for example.
LF (low frequency) and DC measurements shall be carried out with an oscillo- scope together with a 10:1 probe.
•For receiver measurements, a signal generator specified for frequencies up to 2000 MHz is required. The signal generator is connected to the antenna port of the repair jig. Most of the radio communication testers, like CMU200, can be used as a signal generator, but make sure to have a continuous (CW) signal without modulation for alignment purposes.
Transmitter output level measurements shall be done with a power meter which is connected to the antenna port of the repair jig.
Always make sure that the measurement set-up is calibrated when measuring RF param­eters at the antenna port. Remember to put the correct losses of the module repair jig and the connecting cable in Phoenix or in the set-up programs of the RF generators when realigning the phone.
Apart from key-components described in this document, there are a lot of discrete com­ponents (resistors, inductors and capacitors) for which troubleshooting has to be done by checking its proper soldering and complete assembly on the PWB. Capacitors and resis­tors can be checked by means of an ohm-meter, but be aware in-circuit measurements should be evaluated carefully.

Test conditions

Rx tuning of the 26 MHz reference oscillator (VCTCXO) is temperature sensitive
because of the estimations of <AFC_value> and <AFC_slope>. According to the Produc­tion Test Specification DCS02294-EN-0.5, the ambient temperature has to be within a temperature range of 22°C to 28°C.
Most RF semiconductors are static discharge sensitive. ESD protection must be taken into account during repair (ground straps and ESD soldering irons).
The RF ASIC Helgo is moisture sensitive. Therefore, the ASIC must be pre-baked prior to soldering.

Fault finding chart of the receiver

During fault finding, the calibration procedure is used to find out, whether all bands are affected (error in common part of the Rx chain) or only one band (error in a Rx part of the failed band). Take care not to save calibration values to the phone memory, which are out of limits. Find the error first and repair it.
When a defective phone has been calibrated, a possible error in RX front-end might be masked. In that case, one can get a reasonable RSSI reading, although the front-end shows excessive losses. If it is not sure that incorrect re-calibration has been made, fol­lowing steps shall be carried out:
Check if AGC calibration is within limits.
Check if SNR reading is o.k.
Use an oscilloscope to check levels of “RXI” and “RXQ”.
The RF ASIC generates only single ended I and Q signals (RXI, RXQ). As the A/D converter in UEM requires two differential signals, an artificial mid voltage is generated from
RH-37
Nokia Customer Care 6(b) - RF Troubleshooting Instructions
VrefRF02. The phone layout has dedicated test points for the analogue RX I and Q signals (J512, J513).
The BB part is used to measure those signals by means of RSSI reading. This works only if correct calibration has been carried out in production.
RSSIreading [dBm] = 20log(UBB/U
LSB
) - AGC
calibrated
In order to check the levels and frequencies of RF signals, the following probe can be used (note that only the core lead contacts the test point, the shielding of the coaxial cable does not contact GND during the measurement):
Connect this probe via a coaxial cable and a DC block to a spectrum analyzer. The DC block is important to protect the spectrum analyzer from DC levels, which superpose the RF signal at several test points.
If both RX and TX path seem to be faulty, it has to be checked if the synthesizer is work­ing.

Transmitter

General instructions for TX troubleshooting

Connect the phone to a PC, which has Phoenix Service Software and a dongle installed, using either
repair jig and DAU-9S (RS232) cable or
repair jig and XCS-4 cable via FPS-8 Flash Box or
DAU-9T cable (RS232)
Connect the phone to a power supply (DC voltage of 3.6V) and switch the phone on. The value of the DC voltage of 3.6V at the phone battery connector is crucial.
Connect an RF cable between the test jig and the measurement equipment (GSM test equipment, power meter, spectrum analyzer, or similar).
Make use of an adequate attenuator at the input of your measurement equipment (10dB to 20dB are recommended for a spectrum analyzer or a power meter). Additionally, a DC block is recommended. Assure not to overload or destroy the equipment.
It is strongly recommended to use TXP as external trigger for all TX tunings. External trig­gering gives the following advantages:
trigger for spectrum analyzer (gated sweep)
trigger for oscilloscope
trigger for power meter (avoid exchanging of attenuator and getting better accu­racy in power measurements)
Start Phoenix Service Software and open FBUS connection:
Select Scan Product Ctrl-R
and wait until the phone information is shown in the lower right corner of the screen.
Follow the instructions in the chapters below.

General instructions for synthesizer troubleshooting

Connect the phone to a PC, which has Phoenix Service Software and a dongle installed, using either
repair jig and DAU-9S (RS232) cable or
repair jig and XCS-4 cable via FPS-8 Flash Box or
DAU-9T cable (RS232).
Connect the phone to a power supply (DC voltage of 3.6V) and switch the phone on.
Follow the instructions in the chapters below.

Checking synthesizer operation

Start Phoenix Service Software and open FBUS connection.
Select “Scan Product” (Ctrl-R or in menu File - Scan Product).
Wait until phone information is shown in the lower right corner of the screen.
Set <operating mode> to <Local>.
Open window “RF Controls” (menu Testing - RF Controls)
Set the synthesizer to the following mode:

The setup should now look like this:
The VCO chamber has a fixed shielding lid, which can only be opened by destroying it. To enable measurements with a closed lid, holes are located at positions where the supply voltage VR7, the tuning voltage Vc and the output frequency f
Figure 1: Test holes in the VCO chamber
Tuning voltage Vc @ C7503
Output frequency f
@ R7503
VCO
VCO supply voltage VR7 @ C7500
can be measured.
VCO
The VCO frequency has to be measured with a special probe, which fits into the holes of the shielding lid. A thin coax cable can be used for this purpose, where the outer conduc­tor is removed for 2mm. The isolation and the inner conductor must fit into the hole of the shielding lid and provide a capacitive coupling to the attenuator R7503 at the VCO output. A spectrum analyzer is used to display the frequency.
RH-37
Nokia Customer Care 6(b) - RF Troubleshooting Instructions
Figure 2: VCO probe
The VCO frequency is twice the Rx frequency in the GSM1800 band:
f
= 2 * fRX = 2 * 1842.8 MHz = 3685.6 MHz
VCO
The tuning voltage can be easily measured at the Vc input of the VCO. The corresponding hole in the shielding lid enables the voltage measurement at C7503, which shows the same DC voltage as Vc.
The tuning voltage should be 2.1VDC .. 2.6VDC at f
= 3685.6MHz.
VCO
The tuning sensitivity of the VCO is typically 250MHz/V. The typical relation of VCO fre­quency and tuning voltage is shown in the following diagram:

Even if the PLL is not working properly (Vc outside the valid range), a frequency at the output of the VCO can be detected between 3GHz and 4.4 GHz (if the VCO itself is ok and the supply voltage VR7 = 2.78V is applied).
If the frequency or the tuning voltage have other values than given above, see the fault finding chart for PLL syntesizer below.
