Product Description

This chapter briefly describes the CMD 80 Digital Radiocommunication Tester and explains how to operate the tester for the first time.

The standard tester tests mobile radiotelephones using CDMA (Code Division Multiple Access) technology. Two options (analog and TDMA) are available to support testing of additional wireless technologies.

H The Analog option (Option B82) allows you to test analog mobile radiotele-

phones or test the analog operation of a dual-mode radiotelephones. H The TDMA option (Option B84) allows you to test mobile radiotelephones

using IS-136-A TDMA (Time Domain Multiple Access) technology.

CDMA Description

In CDMA mode, the tester tests are based on the EIA IS-95, EIA IS-95A, TSB-74, and J-STD-008 CDMA standards. The tester emulates a Code Division Multiple Access (CDMA) base station, makes a call to the mobile, and tests for all essential characteristics of a CDMA mobile station. The tester can measure the following key parameters:

First Time Operation

Getting Started

This section contains information for new users who are unfamiliar with the tester. After unpacking, use the following procedure to verify proper operation of the tester.

Power Connection

Use the power cord supplied with the tester to connect to the local supply as follows:

1. Connect the power cord from the rear panel to the AC supply.

The tester accepts supply voltages from 110 VAC to 240 VAC (50 Hz to

400 Hz) (refer to Appendix A:Specifications, Table A–11 on page A–11).

2. Switch the tester power on by first pressing the rear panel power switch and

then pressing the front-panel power switch. If necessary, adjust the front-pan-

el CONTRAST control to optimize the display legibility.

NOTE. When the main power switch (on the rear panel above the power connector) is in the OFF position, the tester is disconnected from the AC power supply.

When the main power switch is in the ON position and the front-panel power switch is in the STANDBY position, voltage is supplied to only the reference frequency oscillator and the front-panel STANDBY indicator (yellow LED). When the front-panel power switch is in the ON position (green LED lighted), all of the tester modules are supplied with operating voltage.

Call to Mobile (MS Tests)

When you press the CALL TO MOBILE softkey for MS TESTS (Service Option 2 as specified in IS-126), the tester displays the menu shown in Figure 3–10.

Figure 3–10: Call established menu for ms tests

This menu displays measurements for the mobile station on the left side of the display and displays base-station parameters on the right. The displayed results are updated about once a second. The tester displays any value that exceeds the limits established during configuration as inverse video (white on black). Refer to Configuration starting on page 3–48 for setting limits.

At this menu level, data transfers to the mobile unit at the full rate. The network status box in the upper right corner of the display shows the rate set that is in use for the call.

The value in the TOTAL POWER EXPECTED field is an internal tester calculation based on the presumed application of the open loop power control algorithm. The maximum value is limited by the reported power class of the mobile station. This method of determining expected power is used for all tests except the Maximum/Minimum Output Power test.

NOTE. For accurate expected power readings, ensure that you have properly set the external gain or attenuations settings (refer to RF CONNECT/EXT ATTEN on page 1–16).

Open Loop Time Response. Press this softkey to test the open-loop power control of the mobile station in response to an increase or decrease in base station total power. The default increase or decrease for this test is 20 dB. Figure 3–11 shows the response to this test.

Figure 3–11: Open loop time response display

The tester performs an initial test when it opens this menu; you can perform additional measurements by pressing the STEP UP and STEP DOWN softkeys. You can change the step size and direction by pressing the CONFIG front-panel key. The minimum increase or decrease is 1 dB.

NOTE. The measurement display indicates all step changes with a positive slope.

During the open-loop test, the closed-loop power is controlled to prevent unwanted interaction; this is achieved by alternately sending up and down power control bits to the mobile station.

Defective mobiles can produce power spikes at certain power steps during the OLTR test, which can result in a digitizer overflow in the tester. Digitizer overflow is reported as “OVL” instead of “– – –” in the INITIAL MS POWER display. Displaying “– – –” indicates that no measurement has been made.

When this overflow condition occurs neither the front panel display nor the GPIB results data buffer are updated. They retain and display (or return) the values of the most recent successful measurement. If the INITIAL MS POWER display shows “OVL”, ignore the displayed results.

Receiver Quality

Use this softkey to set up tests of the performance of the mobile receiver. Two modes of operation are available: continuous mode or single shot mode. You can toggle between the modes by pressing the upper left softkey. When you select the continuous mode, you can press the softkey for the BS Signal or Environment parameters you want to change and vary the value by using the VAR control (see Figure 3–15).

In continuous mode, the tester continuously performs the receiver quality test and displays the frame error rate over the interval of the most recent number of frames. You can set this frame error rate interval (CONTINUOUS INTERVAL) in the configuration menu (refer to Receiver Quality Configuration Menu on page 3–23).

Figure 3–15: Receiver quality sensitivity (continuous)

If the FER exceeds the maximum FER limit, the FER is displayed in inverse video (white on black). The frame errors are also displayed in reverse video if they exceed the number determined by the selected maximum FER and continuous interval. AUTO STOP is not applied in CONTINUOUS mode.

of frames that you set (single shot duration) is reached.

H If you have the auto stop function turned on, the test stops when one of the

following conditions occurs:

H The confidence level that you set is reached. H The frame errors reach the maximum limit, based on the single-shot

duration and maximum FER that you set. Simply exceeding the maximum FER limit will not stop the test, since a falsely high FER can be generated in the initial portion of a test.

H The number of frames that you set (single shot duration) is reached.

Receiver Quality Configuration Menu. While in a receiver quality test menu, you can press the CONFIG front-panel key to display the configuration menu for that particular test (see Figure 3–17).

Figure 3–17: Sensitivity configuration menu

You can use the configuration menu to set the following parameters for the receiver quality tests:

H Single shot duration. Press the SINGLE SHOT DURATION softkey to set

the number of frames that are tested. This parameter is used when you perform a receiver quality test in the single shot mode. The test stops when the number of frames that you set is reached.

H Confidence level. Press the CONFIDENCE LEVEL softkey to set the level

of confidence to which you want to test. The tester uses this parameter when you have selected the single shot mode of operation, and you have turned on the auto stop function. If the frame errors do not exceed the maximum, the tester will execute the test until the probability of an acceptable frame error rate reaches the confidence level that you set. At this time, the tester will stop the test. (If the confidence level is not reached, the test stops when the single shot duration is reached.)

Use of the confidence level allows a manufacturer to improve the throughput of a test station by running the receiver quality test only long enough to obtain the desired confidence level.

H Continuous Interval. Press the CONTINUOUS INTERVAL softkey to set the

number of frames that you want the tester to use to compute the frame error rate for the continuous mode.

H Data rate. Press the DATA RATE softkey to set the traffic channel data rate.

The selections for the data rate are: FULL, HALF, QUARTER, or EIGHTH.

H Auto stop. Press the AUTO STOP softkey to toggle the auto stop function on

or off. When auto stop is on, the tester performs a single shot receiver quality test until the number of frames that you set (single shot duration) is reached or until one of two conditions occurs:

H The confidence level that you set is reached. H The frame errors reach the maximum limit, based on the single-shot

duration and maximum FER that you set. Simply exceeding the maximum FER limit will not stop the test, since a falsely high FER can be generated in the initial portion of a test.

H Maximum frame error rate. Press the MAXIMUM FER softkey to set the

maximum frame error rate. The frame error rate is the percentage of bad frames with respect to the total number of frames tested. The maximum frame error rate is the frame error rate limit used to control the inverse video display of the FER and the FRAME ERRORS fields. For example, in Figure 3–17 the maximum frame error rate is set to 0.5%. The single shot duration is 1000 frames. Therefore, the maximum number of frame errors is 5.

H Total power. Press the TOTAL POWER softkey to set the transmitted power. H Traffic level. Press the TRAFFIC LEVEL softkey to adjust the level of the

forward traffic channel in the forward CDMA channel. The TRAFFIC LEVEL softkey specifies the FULL rate traffic channel level.

H AWGN LEVEL (Additive White Gaussian Noise Level). This option

provides additional noise to more closely simulate actual operating conditions. The tester displays the AWGN LEVEL softkey when the optional AWGN system is installed. Press the AWGN LEVEL softkey to adjust the level of the AWGN generator. Press the ON or OFF front-panel keys to turn the AWGN generator on or off.

The tester’s additive white gaussian noise (AWGN) signal is a calibrated, wideband (1.8 MHz) signal simulating white noise. The AWGN power is measured across the entire 1.8 MHz bandwidth. In some tests, such as those specified in IS-98, the described noise power is measured across the

1.23 MHz bandwidth of the CDMA signal. To use the tester’s AWGN signal for these types of tests, you must set the AWGN level 1.1 dB higher than specified in IS-98 to compensate for differences in bandwidth.

For example, in IS-98, section 9.3.3, Demodulation of Forward Traffic Channel in Additive White Gaussian Noise, the specification indicates that the total AWGN power should be 1.0 dB greater than the total forward traffic channel power. This specification assumes that the AWGN power is measured in a 1.23 MHz bandwidth. Since the tester uses a 1.8 MHz bandwidth to measure its AWGN power, you must compensate for the difference in noise measurement bandwidth by setting the AWGN level in the tester 1.1 dB higher than the value specified in the IS-98 test specification.

In this example, where the IS-98 specification calls for a 1.0 dB greater AWGN level than the forward traffic channel level, you must set the tester’s AWGN setting to 2.1 dB (the 1.0 dB from the IS-98 specification plus

1.1 dB for bandwidth compensation).

NOTE. The total output power of the tester is the sum of the Forward CDMA signal plus the AWGN signal. When the Forward CDMA signal is within 10 dB of its maximum power output, the AWGN signal is turned off. Once the Forward CDMA signal is no longer within 10 dB of its maximum power, the AWGN signal level may be set to a new value.

H Base station carrier frequency offset. Press the BS CARRIER FREQ

OFFSET softkey to enter the frequency offset by which you want to shift the base station carrier. This allows you to test if the mobile station tracks the base station frequency.

Total Power = Syn + Pg + P1 + P2 + P3 + P4 + P5 + OCNS Sync, Paging, and Traffic channels are included in this equation, but may be

ignored for the purpose of this discussion. Only the Pilots (P1 through P5) and OCNS will be discussed;

H Underdriven

When the combined output of the Pilots is “low”, the output of the OCNS

must be correspondingly “high” in order to make up the difference and

insure that the specified Total Power is produced. In like manner, when the

Pilots are “high”, the OCNS must be “low”. The OCNS must adjust

automatically with changes in the Pilot Levels in order to maintain the

specified Total Power.

A CDMA chipset controls the distribution of power among the CDMA

signal constituents. There are high and low gain components within this

CDMA: Manual Test (Signaling)

chipset. These gain components have been allocated to the CDMA signal constituents in a “uniform” manner. Pilots 4 and 5, though, must share these resources with the OCNS.

If Pilots 4 and 5 are configured by the user with high gain components, the OCNS will be left with only low gain components. This may leave the OCNS with insufficient capability to make up the difference in the Total Power when the combined Pilot Output is “low”.

In this circumstance, the “Underdriven: Increase The Pilot Level(s)” message will be displayed:

The OCNS level will be replace with a “–––”, indicating its exhausted (“topped-out”) capability. The GPIB command set has related queries and return values.

An alternative to increasing the Pilot Levels would be to re-configure one or both of Pilots 4 and 5 from high gain to low gain, allocating greater capacity to the OCNS.

Softer Handoff

H Overdriven

Each Pilot level is expressed in dB, based upon a ratio relative to the specified “Total Power”. If the sum of the fractional components exceeds the value “1” (unity), the “Overdriven” warning will be displayed:

The OCNS level will be replaced with a “–––”, indicating that it can no longer reduce its level in a manner that will compensate for the elevated Pilot levels. The GPIB command set has related queries and return values.

Press the SOFTER HANDOFF softkey to display the SOFTER HANDOFF menu. See Figure 3–20. Softer handoff measurements allow the user to add a second sector. The user can then evaluate the phone’s ability to incorporate a second sector, correlate transmitted data from both primary and secondary sectors, and complete a handoff to a second sector. A new state is defined when in softer handoff mode: CSH.

Softer handoff occurs over eleven pre–determined steps. At each step, the gain levels for the primary and secondary sectors will be adjusted. Also, at each step two measurements will be made:

3–30

1. An FER will be run in continuous mode, and

CDMA: Manual Test (Signaling)

2. The mobile will be queried for the pilot power for both primary and

secondary pilots. This measurement is actually run upon entering the softer

handoff page, and will continue until the page is exited. Here is an example of the handoff process: On entering the softer handoff page, only the Keep bit for the primary sector

should be set. H A neighbor list message is sent upon entering the softer handoff page to

make the mobile aware of the second pilot channel.

Figure 3–20: Softer handoff menu

H As the user presses the step up/step down buttons, the power ratio between

the primary and secondary sectors will be changed. H As the pilot power of the secondary pilot exceeds T_ADD, the mobile issues

a pilot strength measurement message (mobile has moved this pilot from

neighbor set to candidate set). This message will cause the CMD80 to issue a

handoff direction message, which includes the PN offsets of both pilots. This

message will cause the mobile to move the secondary pilot into the active

set. After the mobile successfully acquires the new traffic channel, it will

then respond with a handoff completion message.

At this point, the mobile is combining the power of both traffic channels.

The keep bit for both pilots should now be set. The keep bit for the primary

sector will be displayed in reverse video. H As the user continues to press “Step Up” and power of the primary level will

drop below T_DROP. At this point, the mobile starts the T_TDROP timer.

When this timer has expired, the mobile will then issue a pilot strength

measurement message.

CMD 80 Digital Radiocommunication Tester User Manual

3–31

CDMA: Manual Test (Signaling)

H The CMD80 will then issue a handoff direction message, which will only

contain the PN offset for the secondary pilot. The mobile will then move the Primary pilot from the active set to the neighbor set and return a handoff completion message.

After a softer handoff is completed from the primary sector to the secondary sector, the secondary sector becomes the new primary sector. To indicate this, the keep bit for the new primary sector is displayed in reverse video (regardless of the primary/secondary titling of the display boxes).

If the total power is changed during the FER, the FER will restart.

For each of the eleven handoff steps, summarized in table 3–2, the power of each sector’s channels (relative to other channels in that sector) will remain constant at -7 dB for the pilot, –15.6 dB for the traffic, –12.0 dB for the primary paging and -16.0 dB for the primary sync. Each of the eleven steps are represented as the power of the secondary sector relative to the primary sector. When the STEP UP button is pressed, the gain levels for the secondary sector will be increased, while the gain levels for the primary sector will be decreased. When the STEP DOWN button is pressed, the opposite will be true.

If a softer handoff has been completed from the primary to the secondary sector, the completed handoff will now be reflected in the new PN offset value seen when returning to the Call Established menu. The new secondary sector PN offset will be automatically set at 10 above the old value.

If the handoff is not completed, the original PN offset values will be retained. The sector that last had the solitary keep bit is the Primary Sector.

Handoffs/Transitions

Press the HANDOFFS/TRANSITIONS softkey to display the HANDOFFS/ TRANSITIONS menu for the CALL ESTABLISHED mode. See Figure 3–21. You use this menu to either handoff an established call to another network, system, and/or standard, or to make a local transition, such as from RATE SET 1 to RATE SET 2.

NOTE. The menu displays the previous NETWORK HANDOFFS selections. The selections are retained until you change them.

Figure 3–21: Handoffs/transitions menu for call established (MS tests)

To handoff a CDMA call, perform the following procedure:

NOTE. The tester does not support handoffs between TDMA and CDMA.

1. In the NETWORK HANDOFFS side of the menu, select the network,

system, and standard to which you want to handoff the call. Table 3–3 lists the supported handoffs with all options installed.

2. To configure the base station signal for the system to which you are handing

off, press the BS SIGNAL CONFIG softkey. For information about configuring the operating parameters of an analog

base station, refer to ANALOG BS SIGNAL CNFG on page 3–160. For

information about configuring the operating parameters of a CDMA base station, refer to CDMA BS SIGNAL CNFG on page 3–49.

3. Press the CALL softkey to select either MS TESTS or VOICE LOOPBACK.

4. Select the RATE SET/VOCODER (CDMA system only).

If you selected CDMA as the system, a RATE SET/VOCODER softkey is displayed that allows you to select the rate set. The selections available for the rate set and vocoder type depend on whether you selected MS TESTS or VOICE LOOPBACK for CALL. For MS TESTS, the RATE SET/VOCODER softkey toggles between RATE SET 1 and RATE SET 2. For VOICE LOOPBACK, the RATE SET/VOCODER softkey cycles through RATE SET 1 BASIC (which specifies the Basic vocoder), RATE SET 1 ENHANCED (which specifies the Enhanced vocoder), and RATE SET 2.

NOTE. If the network handoff you selected is not implemented in the tester, the tester displays the message “The configured handoff is NOT currently available.” In this case, the tester does not display the EXECUTE softkey.

5. Press the EXECUTE softkey to make the handoff.

In the LOCAL TRANSITIONS side of the HANDOFFS/TRANSITIONS menu, you can use the softkeys to make a local transition, such as from RATE SET 1 to RATE SET 2.

Which softkeys appear in the LOCAL TRANSITIONS side of the menu depends on the currently active system, the type of established call (MS TESTS or VOICE LOOPBACK), the rate set, and the vocoder. For illustration purposes, the following figure shows all the possible choices. In the actual menu, the type of call that is currently active will not appear as a choice.
