Tesla for Windows Operating System

The name TESLA, when used by Nokia, is an acronym for TEst and Service Locals Application. Tesla for WIndows (i.e. WinTesla) is a
software package designed to operate in the Microsoft Windows environment. The software package is made of two modules, the Wintesla core module and a service software module. The Wintesla module is similar to an operating system for various service modules. In this way many Nokia products can be serviced using one common software package, running different service modules (in this case, for the Nokia 2180).
Note: The Wintesla core module MUST be installed for ”any” service module to run.

Installing WinTesla On Your Hard Disk

The WinTesla core software is delivered on a 3.5” diskette and is protected with a protection “key” (PKD–1), which must be attached to the parallel port LPT 1 when the WinTesla service software is being used.
NHD–4
To install the WinTesla core software package, proceed as follows:
Note: For instructions on installing the HD881 service module (see Installing the
HD881 Service Module)
Insert the WinTesla Application diskette into drive A: of your PC. From DOS ( NOT running windows ) type
A: INSTALL <Enter>
From Windows File Manager double click the mouse on
a:\install.exe
Follow the instructions given and use the Repeat this procedure for the required module installation using the

Common User Interface

Due to the modular design of WinTesla, various generations of Nokia products can be serviced, while sharing a similar user interface. The common user interface is explained in the first part of this document and is followed by the specific module information.
The software can be used to control the phone by entering commands via the keyboard of a PC/AT – running MS Windows 3.1 or 3.11.
Note: Windows 95 and Windows NT are not supported.
This document refers to WinTesla Version 4.60 or greater.

Mechanical Connections

The software controls the phone via a separate adapter (DAU–2) connected to the serial port of the PC and to the phone’s bottom connector using the Nokia proprietary communication method called M2BUS.
Attach the protection key PKD–1 to parallel port one (25–pin female D–connector) of the PC. When connecting the PKD–1 to the parallel port be sure that you insert the PC end of the PKD–1 to the PC (male side).

Using Wintesla

Phone Independence

The WinTesla application, “WinTesla.exe”, is phone independent. It relies on separate, phone specific, “modules” to provide communication, menus and test algorithms.
Technical Documentation
Figure 4. WinTesla with loaded interfaces
For each phone type – or product family – a phone interface module and menu module are required. The modularity of WinTesla allows support for other languages, so one phone type may have one phone interface module and several menu modules, all in different languages.
WinTesla allows you to select the language you wish to use (if available), and will automatically load the correct phone interface module for the connected phone. When a different phone type is connected, WinTesla will load the new phone interface and associated menus.

1. Fault Log Application.
The aim of the Fault Log application is to provide NMP After Sales Companies worldwide a standard method for the collection of Fault and Repair Data from their service process’s. This information can also be used by NMP R&D and Manufacturing organizations as well.
The Fault Log application can be regarded as a data entry sub–routine run from the WinTesla Service Software package at the end of a repair. This allows for quick and uniform recording of the service performed on the product.
Each product repaired, will generate one unique record in a FaultLog file consisting of up to 37 data fields containing information about the product and how it was repaired. This information is read automatically where possible, from the products own internal EEPROM and then entered manually by the Service Technician to form a complete service record.
NHD–4
For more advanced implementations, the repair records are copied and collected by the electronic mail system installed in the Service Center and are sent electronically to a Central Service Database located in Finland.
Completing a FaultLog Record
Once WinTesla has been configured correctly it operates in the following manner:–
Wintesla automatically reads the product details from the products EEPROM and writes them as a record to a pre–determined file.
Proceed with the repair task, utilising a combination of software driven tuning and hardware modifications.
On completion of the repair task you have a choice:
A.)With the product still connected to the PC, manually display the repair data entry screen by selecting Function Button F9.
B.) Alternatively, the product can be disconnected and the next product for repair connected in its place.
So long as Automatic Prompting is enabled then the previous products repair data entry screen will be displayed.
– Enter the repair work performed on the product in the repair
data screen.
– Check the automatic data for this product, read earlier, to
ensure its accuracy.
– When satisfied with the data, save the entry. This process
adds a complete record containing the product details and the repair details to the FaultLog output file.

The output file can then be manipulated by a number of different systems, as required, as a detailed record of the product fault.
To attempt to record all of this information 37 data fields are defined for each FaultLog record. These can be split as follows:–
– Product definition information fields – Repair / fault information fields.
Most products have their information stored in EEPROM, WinTesla automatically reads this information from the EEPROM and writes it to the FaultLog record. This part of the record is shown below.

AMPS Tuning
Analog Bias Current Tuning
The purpose of this tuning is to optimize transmitter‘s efficiency. Bias tuning is needed if:
– PLL circuit (N500) is replaced – Any of the power amplifiers V110, V111, V112, V113 or the duplex filter
is replaced – Any of power amplifier resistors are replaced
This affects only power consumption and thus gain and linearity of power amplifier.
Description of Tuning
This tuning sets the bias current to the CLY–10 (V113) final PA gain stage for AMPS mode operation at output power level 7. The TXB PDM is used to set this bias. The bias is set to provide 100 mA of current to the CLY–10 in this state. This 100 mA current is the amount of current draw above the quiescent state of the phone in AMPS mode, as described in the AMPS Mode Quiescent Current section 3.1. Note that the CLY–10 will draw additional current at higher output AMPS power levels. This is due to self biasing by the drive signal.

AFC Tuning
This tuning is done to calibrate the VCTCXO oscillator frequency. This tuning is needed if the VCTCXO (G300), any component of AFC–line
or the CDRFI (N700) is changed.
Description of Tuning
This procedure tunes the VCTCXO to 15.36 MHz. The unmodulated AMPS transmitter carrier on channel 384 is used to perform this test. The output carrier is monitored with a spectrum analyzer with a 10 kHz span. The VCTCXO is tuned by adjusting the AFC PDM until the carrier is on frequency at 836.52 MHz within 200 Hz. For standard AFC operation the RX_SLOPE PDM is high, at approximately 3.15 V.

Deaf Channel Frequency Tuning
This tuning is done to calibrate the VCTCXO oscillator frequency to adjust for “deaf” or “blocked” AMPS channels.
This tuning is needed if the VCTCXO (G300), any component of AFC–line or the CDRFI (N700) is changed.
Description of Tuning
This is a secondary tuning done on the VCTCXO for a special case involving AMPS channels 184, 440 and 696, known as the Deaf channels. This tuning is performed exactly as it was in the AFC Tuning above, but now channel 440 is used rather than channel 384. In this case the RX_SLOPE PDM is low at approximately 0.0 V. Again the AFC PDM is adjusted to tune the transmit carrier to within 200 Hz of the center frequency, this time 838.20 MHz. Consult the HD881 Synthesizer Functional Description for more information on the Deaf Channel functionality of the synthesizer.

RSSI
This step consist of tuning the analog mode reference value for the receiver signal strength meter.
This tuning is needed if FM detector (D1); any parts of RX–chain; duplex filter or saw filter has been changed
Note: Take into account any cable loss.
Description of Tuning
This tuning records the RSSI values for low and high power received signals. This is done by feeding a –95 dBm signal into the AMPS receiver at channel 384 with modulation of 8 kHz FM, 1 kHz audio. The RSSI voltage generated by the AMPS receiver IC (D1) routes to the MCU, pin
58. The MCU reads the RSSI value resulting from its onboard A/D converter. For the –65 dBm input signal this digital value is stored in EEPROM as RSSI_HI. This process is repeated for a –65 dBm modulated input signal, and the stored value is termed RSSI_LO. The RSSI values read by the MCU are 10 bit numbers.
Technical Documentation
Analog RSSI level tuning steps:
– Using the JBS–7 service jig, replace the standard battery of the phone

CDMA Tuning
RX Offset Tuning – (RX/TX)
The purpose of this tuning operation is to calibrate the mid point of the CDMA Receiver’s dynamic range.
This tuning is needed if the duplexor, CDGACR (N1) or BBFIL (N2) is changed.
Definition of Tuning
The purpose of this tuning is to center the dynamic range of the RxDac to correspond to the midpoint of the dynamic range of the CDMA receiver. A –65 dBm 881.62 MHz signal is fed into the phone. –65 dBm is the midpoint of the –25 to –105 dynamic range of the CDMA receiver. The RX_OFFSET PDM is adjusted until the RxDac is at its midpoint of approximately 200H. The RX/TX designation on the name of this tuning implies that both the receiver and transmitter are functioning when this tuning occurs. A separate tuning must occur when the transmitter is not on, hence the reason for the RX_OFFSET (RX) tuning.

Rx Slope
The purpose of this tuning operation is to calibrate the linear relationship, or slope, between a change in the received power by the CDMA receiver.
This tuning is needed if the duplexor, CDGACR (N1), CDSB (D704), CDRFI (N700) or BBFIL (N2) is changed.
Definition of Tuning
This tuning determines the linear relationship, or slope, between a change in the received power by the CDMA receiver. To do this a CW signal is fed into the CDMA receiver. The initial CW signal power is stored as BPOW1. Next, the CW signal power is incremented until the RxCtr changes by 256 steps. The CW signal power required to do this is recorded as BPOW2. The difference between BPOW1 and BPOW2 should be approximately 32 dB. From this data the RX Slope is determined. It is then manipulated mathematically so that the RX Slope equals “1”. When it does, a one bit change in the RxCtr will result in a 1/8 dB change in receiver gain. The RX/TX designator on the name of this tuning implies that the transmitter is on when this tuning is performed. A separate tuning must occur when the transmitter is not on, hence the reason for the RX_Slope (RX) tuning.

To do this a CW signal is fed into the CDMA receiver. The initial CW signal power is stored as BPOW1. Next, the CW signal power is incremented until the RxCtr changes by 256 steps. The CW signal power required to do this is recorded as BPOW2. The difference between BPOW1 and BPOW2 should be approximately 32 dB. From this data the RX Slope is determined. It is then manipulated mathematically so that the RX Slope equals “1”. When it does, a one bit change in the RxCtr will result in a 1/8 dB change in receiver gain. The RX/TX designator on the name of this tuning implies that the transmitter is on when this tuning is performed.

Rx Gain Switch Calibration
The purpose of this tuning operation is to calibrate the gain differential of the receiver system with the LNA on and off.
This tuning is needed if the LNA (V12), N701 or N702 is changed
Definition of Tuning
This operation determines the gain differential of the receiver system with the LNA on and off. The CDMA receiver system is then calibrated accordingly. To do this a constant level CW tone is fed into the CDMA receiver. The LNA is turned on and the received signal strength to the CDSB ASIC (D704) is read and stored. This is the also known as the RxCtr value. With the same input signal the LNA is then turned off and the RxCtr is read again. The dB power difference between the two RxCtr values is equivalent to the gain that the LNA provides.

CDMA TX Bias Tuning
The purpose of this tuning operation is to calibrate the Power Amplifiers bias current limit.
This tuning is needed if the Power Amplifier (V113) or any transistor in the TX chain (V110 – V112) is changed.
Definition of Tuning
This tuning sets the bias current limits on the CLY–10 (V113) final PA gain stage. Bias current on the CLY–10 is dynamic in CDMA operation. The TXB PDM is used to set this bias. Low power is defined as less than or equal to +10 dBm of output CDMA TX bandpower. For the low power case the bias is set to provide 100 mA of current to the CLY–10. Max Power is defined as greater than or equal to +23 dBm of output CDMA TX bandpower. For the Max Power case the bias is set to provide 250 mA of current to the CLY–10. Between Low and Max Power the bias current ramps up linearly from 100 to 250 mA. These currents described are the amount of current draw above the quiescent state of the phone in CDMA mode. The figure below better describes the TXB Slope.

Align TX Gain Limiting Tuning
The purpose of this tuning operation is to calibrate the Maximum Power output in CDMA mode.
This tuning is needed if the Power Amplifier (V113) or surrounding components of is changed .
Definition of Tuning
This tuning sets the upper limit on the output power of the CDMA TX. To do so, the CDMA TX is initially railed high, providing the maximum output power that the phone’s software will allow it to produce. This output power is then reduced until it is approximately 24.5 dBm. This is accomplished by decreasing the value of the TXI_REF PDM. The value of TXI_REF PDM determines the TX limit by comparing itself to the TXI voltage generated by the detector. It is important to keep in mind that this 24 dBm value refers to power within the 1.23 MHz CDMA channel band. Thus it is a bandpower measurement, not a peak power measurement.

Aux. AGC Tuning
The purpose of this tuning operation is to calibrate the Automatic Gain Control circuit in CDMA mode.
This tuning is needed if CDCONT (N201), N1, N2, N100 or N700 is changed.
Aux. AGC is an auxiliary transmitter gain control feature implemented to improve the signal to noise ratio of the CDMA TX output. The figures below will assist in the explanation of the Aux. AGC functionality.
The gain of the CDMA transmitter is controlled by two devices, the CDAGCT IC (N100) and the AT–109 variable attenuator (V106). CDMA TX output power is controlled by the CDAGCT IC across the dynamic range of –50 dBm to 15 dBm. The 15 dBm output point is referred to as the Switch Point. Above the Switch Point (15 dBm), the AT–109 variable attenuator controls the output power level. This secondary gain control mechanism is referred to as Auxiliary AGC (Aux. AGC). A more thorough description of Auxiliary AGC is found in the Transmitter Troubleshooting Manual and Functional Description.
Technical Documentation
Below the Switch Point (less than 15 dBm CDMA TX power) the attenuation of the AT–109 is set to its maximum level of tuned attenuation. Above the Switch Point this attenuation is decreased, thus increasing the overall gain of the CDMA TX chain. The Aux. AGC circuit is tuned to provide a 10 dB dynamic range of attenuation. Without this 10 dB of attenuation in place the output power increases 10 dB above the switch point to approximately 25 dBm. In practice the 25 dBm may not be reached due to the TX Gain Limiting feature. Figure 5.4.1 below depicts this functionality.
The amount of attenuation provided by the AT–109 (V106) is controlled by the voltage VC. VC is a function of the AGC_REF PDM. For minimum attenuation the AUX. AGC PDM voltage is typically 0.75 V, resulting in
3.25 V for VC. For maximum attenuation the AUX. AGC PDM voltage is typically 10.0 mV, resulting in 1.50 V for VC. The Auxiliary AGC can be manually adjusted using the AGC_REF PDM controls found in the Service Software.

Band Power 1 – 2 Tuning (BPOW1 – BPOW2) Description of Tuning
For this step the AGC_REF PDM is adjusted to provide 5 dB of attenuation from the AT–109. The CDMA TX output bandpower will then be approximately 11 dBm, 5 dB off from the initial 16 dBm set in the BPOW1 step. This bandpower position is referred to as BPOW2. This 5 dB is necessary to move the AT–109 dynamic range off the curved portion of the attenuation response as seen between points BPOW1 and BPOW2.

TX Slope Tuning Definition of Tuning
This tuning determines the linear relationship, or slope, between a change in the output bandpower of the CDMA TX and a change in the TxDac. To do this the CDMA transmitter is turned on and set to an output bandpower corresponding to a TxDac value referred to as TxDac1. The resultant bandpower is read and stored as BPOW1. Next, the TxDac is decremented by a fixed amount that should result in approximately 32 dB less output bandpower than the initial state. This TxDac value is called TxDac2. Again the output bandpower is read, and stored as BPOW2. From this data the TX Slope is determined. It is then manipulated mathematically so that the TX slope equals “1”. When it does, a one bit change in the TxDac will result in a 1/8 dB change in output power. The following graph should help describe the TX Slope concept.

5. Initiate the CDMA Troubleshooting Mode from the Test menu of the Service Software.
6. Using the PDM controls Adjust the TX_OFFSET PDM until the output bandpower is –8 dBm.
7. Again use the CDMA TX Manual Gain controls located in the CDMA tests selection of the Test menu.
8. Use this control to achieve approximately 10 dBm of CDMA TX output bandpower.
9. From the PDM controls, adjust the TXB PDM until the total current draw of the phone is 100 mA greater than the CDMA Mode Quiescent Current, determined in step 4. Accomplishing this, verifies Low CDMA TX Power Bias.

10. Repeat steps 3 – 5, but for 23 dBm of CDMA TX output bandpower, and 250 mA of current over the CDMA Mode Quiescent Current, determined in step 4. Accomplishing this verifies Max CDMA TX Power Bias.
Troubleshooting
A failure of this test could be attributed to a number of things. Foremost, both the transmitter and the synthesizer have to be functional. The TXB PDM is adjusted throughout this tuning, as is the TX Offset PDM. Ensure their operation. The negative voltage generator N200 and the VTXS supply should also be inspected for proper operation. If these tunings is unable to achieve the minimum amount of bias currents there may be a faulty, misplaced or wrong value component in the bias circuitry supporting the CLY–10.
TX Gain Limiting Tuning Functionality Test

The CDMA TX Gain Limiting functionality can be verified by performing the TX Gain Limiting tuning procedure found in the tuning menu of the Service Software. Another option is to perform the steps below:
1. Initiate the CDMA TX Manual Gain controls from the CDMA Test menu located in the Service Software.
2. Set the CDMA TX Gain to maximum.
3. From the PDM controls, adjust the TXI_REF PDM to 127 decimal. The phone should achieve approximately 27 dBm of CDMA output bandpower.

4. Adjust the TXI_REF PDM until the CDMA TX output bandpower is approximately 24.5 dBm. If this can be accomplished, the TX Gain Limiting functionality has been verified.
Troubleshooting
A failure of this test might result from a faulty transmitter, or problems within the CDMA TX gain control circuitry. The operation of the CDCONT should be checked, as should the TXI_REF PDM, and the TXI voltage. If the transmitter has lost any gain, this test will most likely fail.
Aux. AGC Tuning Functionality Test
Manual Test
Auxiliary AGC functionality can be verified by performing the Aux. AGC tuning from the Service Software. Another method would be to perform the manual verification steps described below.
1. Maximize the CDMA TX output bandpower by initiating the CDMA Troubleshooting Mode.
Technical Documentation
2. From the PDM controls, adjust the AGC_REF PDM to 0. This sets the AT–109 to minimum attenuation.
3. Next adjust the TX_OFFSET PDM until the CDMA TX output bandpower is approximately 16 dBm. This verifies the BPOW1 step
4. Adjust the AGC_REF PDM to provide the 5 dB of attenuation, bring the output bandpower to approximately 11.0 dBm. This verifies the next step BPOW1 – BPOW2.
5. Adjust the AGC_REF PDM to provide an additional 10 dB of attenuation, bring the output bandpower to approximately 1.0 dBm. If the additional 10 dB of attenuation is achieved, the third step BPOW2 – BPOW3 is verified. The final 1.0 dBm bandpower is BPOW3.
Troubleshooting
For this step to occur the CDMA transmitter must be functioning, at least enough to achieve 16 dBm of output. The TX_OFFSET and AGC_REF PDMs must work, as well as the AT–109 attenuator. Consult the Service Manual for further information and tests.

CDMA TX Spurious Check
Definition of Test
This test reads spurious emissions levels of the CDMA Transmitter +/– 900 kHz from the center of the channel. For this test the phone is transmitting at its maximum level in CDMA mode. This test can be performed manually with a spectrum analyzer. To do this feed the 2180 RF output into the spectrum analyzer and set the CDMA TX output to maximum. Service Software rails the CDMA TX to maximum for the CDMA TX Quick Test. I recommend using it to put the phone into the proper mode. Use the averaging functionality of the spectrum analyzer to get readings of better precision. Set a marker + 30 kHz off the center frequency of the transmit signal. Set another marker + 900 kHz off the center frequency. The delta between them should be at least 26 dB. This should also be done for – 30 and –900 kHz off center.

3. Set the Resolution Bandwidth of the spectrum analyzer to 30 kHz. Use the averaging functionality of the spectrum analyzer to get readings of better precision.
4. Set a marker + 30 kHz off the center frequency of the transmit signal.
5. Set another marker + 900 kHz off the center frequency.
6. The delta between the two markers should be at least 26 dB.
7. Repeat this test with markers –30 kHz and –900 kHz off the center frequency.
Technical Documentation
The resultant value reported from the automated tester is the power difference (delta) in dB between the 30 kHz and 900 kHz frequency offset positions, as described above
Troubleshooting
The CDMA transmitter must be functioning properly to correctly perform this test. The maximum power level of the CDMA TX must be correct, approximately 24 dBm. The operation of the CDAGCT IC (N100) and the AT–I09 attenuator IC (V106) greatly influence the results of this test. Should this test fail, it is suggested that their health and functionality be inspected. The Service Manual Transmitter Troubleshooting section and Functional Description will provide information and tests for the transmitter chain.
LNA Gain Calibration
Definition of Test
This operation determines the gain differential of the receiver system with the LNA on and off. The CDMA receiver system is then calibrated accordingly. To do this a constant level CW tone is fed into the CDMA receiver. The LNA is turned on and the received signal strength to the CDSB ASIC (D704) is read and stored. This is the also known as the RxCtr value. With the same input signal the LNA is then turned off and the RxCtr is read again. The dB power difference between the two RxCtr values is equivalent to the gain that the LNA provides.

Troubleshooting
Fault with this calibration obviously points suspicion to the LNA functionality. The CDMA RX may also be at fault. The Service Manual Receiver Troubleshooting section and Functional Description will provide further information and test suggestions to troubleshoot this fault.

more details on this function
Check box – Skip download to Flash box
The flash update is done using a two step process. the flash image is downloaded to the flash box in the first step. This takes about 30 to 45 seconds. Then the image is updated on the phone during the second step.
)
see Initialize EEPROM for
This option is useful if you are updating several phones with the same flash image. After completing the first phone update, checking this option will skip the first step of downloading the flash image to the box again. It is not necessary to download the image again because the box will contain the last image loaded unless a loss of power occurs.
