Calibration Procedures

The list below shows all of the calibration procedures that must be performed periodically when testing CDMA mobile stations with the Test Set, including Test Sets configured with an HP 83236B PCS Interface.

"Calibrating CDMA Channel Levels" on page 26 "Calibrating Channel Power Measurements" on page 29. "Calibrating RF Generator Levels" on page 35

Guidelines:

"Zeroing Average Power Measurements" on page 36 "Correcting for RF Path Loss" on page 41. "Determining RF Path Loss" on page 44.

"Recommended Calibration Procedures:" on page 25 provides a checklist of

calibration procedures for various events that could affect the perf ormance of the Test Set.

Guidelines include:

•After "Calibrating CDMA Channel Levels" on page 26 (also known as "PCB CAL") is performed, you must then perform "Calibrating RF Generator Levels" on

page 35 and "Calibrating Channel Power Measurements" on page 29.

• It is highly recommended that "Correcting for RF Path Loss" on page 41 be performed before using the Test Set to make measurements. This procedure eliminates the need for adding level offsets to your test code, and extends the Test Set’s operating range with some mobile stations.

• A 30-minute warm-up period is recommended to allow the Test Set to reach a stable operating temperature.

Approximate time: 8 minutes CDMA channel levels should be calibr ated whenever any of the following events

occur:

• After a 30-minute warm-up period

• After firmware is upgraded

• If a 5° C change in ambient temperature occurs

The Test Set optimizes the level accuracy of CDMA code channels and the AWGN (Additive White Gaussian Noise) generator by measuring the analog I/Q signals on an internal DSP-based voltmet er. Level corre ction factors a re generated by a ROM-based program named PCB_CAL and are applied to gain control DACs, which control the fine level adjustment in the amplitude scaling path.

AWGN

Analog I

Analog Q

Level Correction Factors

Calibrated channel power provides accurate values for Eb/Nt, the ratio between Traffic channel power and AWGN. It is critical that these levels remain accurate. A level accuracy error of 0.8 dB could alter FER from 0.5% to 5%.

Calibrating RF Generator Levels

This procedure applies only to Test Sets configured with an HP 83236B PCS Interface.

Approximate time: 15 seconds RF generator levels should be calibrated whenever any of the following events

occur:

• After a 30-minute warm-up period

• After firmware is upgraded

• If the RF connections to the PCS Interface are adjusted

• If the ambient temperature drifts more than 5 °C after a 30-minute warm-up period

The PCS Interface’s internal compensation factors are used to compute the generator p ath attenuator values and the required signal level from th e Test Set’s DUPLEX OUT port. The RF IN/ OUT path is a uto matica lly d e-coupl ed wi thin the PCS Interface during this procedure, so any RF link to a mobile station will be lost This includes dropped calls and loss of CDMA or analog service from the Test Set.

Zeroing Average Power Measurements

Approximate length of time: 2 seconds Average Power measurements should be zeroed before each measurement or

series of me asurements.

NOTE: A misleading Average Power measurement may appear when low (or no) signal power

is applied to the RF Input! When the RF generator’s output port selection is RF IN/

OUT, some of the signal energy from the Test Set’s generator is detected by the Test Set’s broadband average power meter. This condition does not affect typical CDMA measurements for two reasons: 1) During Averag e Power measuremen ts CDMA gener ator levels are too low to introduce significant energy to the power detector. 2) When the generator level is high enoug h to introduce significant energy to the po wer detector, the mobile station’s sign al power should be with in the range of Channel Power measuremen ts. Channel power measurements are frequency-selective, and do not detect significant energ y from the Test Set’s generator, which is tuned 45 MHz away from the analyzer.

The PCS Interface extends the measurement capability of the HP 8924C to include the PCS frequency range.

The Test Set, when install ed with f irmware r evision A.05.00 or high er, contro ls the PCS Interf ace via the rear-

panel serial AUX CONTROL interface. A rocker switch on the PCS Interface rear panel labeled “HP-IB/Ser” must be in the “Ser” position for serial control.

When switching between the cellular and PCS frequency bands it is not necessary to turn PCS Mode “Off”. This is because the PCS Interface provides conversion bypass paths (bypassing frequency up-conversion on the generator path and frequency down-conversion on the analyzer path) for operation in the cellular band.

7. Connect the mobile-station-under-test (MSUT).

Manual Operation:

Connect the MSUT to the Test Set’s RF IN/OUT connector.

Make sure all connections to the MSUT, including dc power, are made.

Some MSUT’s do not have an RF connection. The MSUT manufacturer will us ually make a fixture, such as a car adapter, that will provide an RF cable connection to the Test Set. The MSUT is then snapped into the fixture and an RF connection is made through an electromagnetic coupler near the MSUT antenna. When setting up a call with these type of MSUT’s, the MSUT may need to be isolated from interfering signals.

8. Turn on power to the MSUT and wait for the MSUT to find digital service.

Manual Operation:

Wait until the MSUT has found digital service (this should take no longer than about 30 seconds).

If the MSUT does not find service, refer to

"Checklist 1. MSUT did not find service" on page 68

Most MSUT’s have a NO SERVICE annunciator that will go out when the mobile station has found service. Other MSUT’s use an LED that indicates when service has been found. If the MSUT is programmed to prefer analog service, and a strong signal from an analog base station is present, the MSUT may not find digital service. If this condition exists, re-program the phone or isolate it from the co mpeting analog signal.

Caution: Do not exceed 6 W continuous power into the Test Set’s RF IN/OUT connector with any transmitter.

Registration provides the Test Set with the MSUT’s identification, thereby enabling the Test Set to correctly address pages. (An alternative method for providing the Test Set with the MSUT’s identification is to enter Phone Number, MIN, or IMSI directly into the MS ID field on the CDMA Call Control screen. This alternative method could result in significant time savings in a production test environment but the numbers you enter must precisely match the internal NAM (Numeric Assignment Module) settings in the MSUT and the MSUT must be non-slotted).

When the Register field is selected, values enter e d in the CDMA Cell Site Configuration screen’s Rgstr SID and Rgstr NID fields are sent to the MSUT in a message called the System Parameters message. This SID/ NID pair causes the MSUT to perform a “zone-based” registration. The Rgstr SID and Rgstr NID fields are set by default to 12. These values do not need to be chan ged unless the MSUT i s programmed to not reco gnize them as valid, or the MSUT recognizes them as its home SID/NID. If either of these conditions exist, change Rgstr SID and Rgstr NID to arbitrary values that are both valid for the MSUT and do not match the MSUT’s home SID/NID.

Checklist 1. MSUT did not find service

If the MSUT won’t find service, refer to t his checklist. If the MSUT has found service but won’t regi ster, refer to

❒ Is the RF cable connected? ❒ Is the RF Channel number correct? (Set the RF Channel on the CDMA Call Control

screen.) Refer to table 1 and table 2.

❒ Is Sector A Power adequate? If i nterference from o ther cellular band signals is present,

Sector A Power may need to be set to a level greater than the instrument preset value of -75 dBm/BW. (Set Sector A Power on the CDMA Call Control screen.) Example: If the MSUT is finding analog service , adjust Sector A Power to -25 dBm/BW, then cycle power on the MSUT. Isolating the MSUT may be necessary.

"Checklist 2. Registration failed" on page 70.

❒ Is the AWGN generator (CDMA Gen Control screen) off? ❒ Is the MSUT programmed “Home Only”? If so, set the SID on the CDMA Cell Site

Measuring Demodulation of Forward Traffic Channel with AWGN

The Test Set performs "Demodulation of Forward Traffic Channel in Additive White Gaussian Noise" as described in TIA IS-98, "CDMA Receiver Minimum Standards."

During this test, FER is meas ured as the Test Set provide s various da ta rates to the

mobile-station-under-test (MSUT) with the Test Set’s AWGN generator turned on.

Test Prerequisites

Determine Cable Path Loss

When using cables to co nnect the equipment, the path lo ss f or the cable(s) should be determined. The Test Set can be used as a source to measure path loss.

Refer to

"Correcting for RF Path Loss" on page 41 if necessary, and then return to

this procedure.

NOTE: The following procedure assumes that an instrument PRESET will be performed as part of

setting up a call. This clears all settings from other tests that may affect the accuracy of this test, and allows the procedure to begin from a known instrument state.

AWGN (Ioc) determines the signal-to-noise ratio Îor/Ioc. The Sector A Power field sets Îor .

To obtain a ratio of -1, set AWGN 1 dB higher in power than Sector A Power.

Ioc is defined as the power spectral density of a band-limited white noise source (simulating interference from other cells) as measured at the mobile station’s antenna connector.

HP-IB Syntax

"CDMA:AWGN:STAT ON" !turns the Test Set’s AWGN generator on. "CDMA:AWGN -74" !sets AWGN to -74 dBM/BW.

Measuring Receiver Sensitivity an d Dynamic Range

The Test Set performs " Receiver Sensitivity and Dyna mi c Range " as described in TIA IS-98, "CDMA Receiver Minimum Standards."

During this test, FER is measured with the Test Set first providing a low level signal, then a high level signal.

NOTE: The following procedure assumes that an instrument PRESET will be performed as part of

setting up a call. This clears all settings from other tests that may affect the accuracy of this test, and allows the procedure to begin from a known instrument state.

1. Make a Service Option 2 call.

See "Setting up a Call" on page 52 if you are not familiar with how this procedure is performed with the Test Set.

After setting up the call, return to this procedure.

NOTE: The RF path loss between the RF output of the Test Set and the RF input of the MSUT must

be corrected for. Correcting for path loss by entering an RF level offset allows the Test Set

analyzer’s auto-ranging algorithm is to work correctly throughout the operating range of the MSUT. Refer to "Correcting for RF Path Loss" on page 41.

Measuring Single Tone Desensitization

The Test Set performs the necessary call processing and FER measurements for "Single Tone Desensitization," but requires a single external continuous wave (CW) signal generator to perform this test as described in TIA IS-98, "CDMA Receiver Minimum Standards."

During this test, an interfering signal (tone) is summed with the Test Set’s outpu t and the FER is measured.

Test Prerequisites

Chapter 3, CDMA Receiver Tests

Measuring Single Tone Desensitization

Determine Cable Path Loss

When using cables to co nnect the equipment, the path lo ss f or the cable(s) should be determined. The Test Set can be used for measuring path loss.

Refer to

"Correcting for RF Path Loss" on page 41 if necessary, and then return to

this procedure.

Recommended Equipment

CW Generator Specifications for the CW signal generator are provided in TIA IS-98, "CDMA

Standard Test Conditions." At the time of this printing, the following signal generators meet these specifications:

• HP 8656B

• HP 8647A

• HP 8657D

Combiner

The Combiner used in this test must provide adequate isolation between the Signal Generator output and th e si gnals generated by the MSUT and the Test Set. At least 15 dB isolation is recommended.
