E1962B cdma2000 ^® /IS-95/AMPS Test Application Revision Information

Transmitter tests

• Code Domain Power Pass/Fail criteria

  The Code Domain Power measurement's pass/fail criteria have been modified to be compliant with the TIA/EIA-98-E specifications for waveform quality. The test was compliant with TIA/EIA-98-D specifications in earlier releases. See Waveform Quality/Code Domain Measurement Description

• Spectrum Monitor Measurement

  The Spectrum Monitor measurement feature has been added. This allows you to find, identify and measure transmitted signals from your mobile phone. It can also be used for spur measurements in the transmit band. See Spectrum Monitor Description .

Receiver Tests

The FER (Frame Error Rate) measurement adds three new measurement results provided to identify the types of frame errors counted by the FER measurement (see Frame Error Rate (FER) Measurement Description ). The three types of errors now identified are:

• Forward Erasures. The number of frames the cdma2000 device was not able to decode.
• Mobile Errors. The number of frames that the cdma2000 device sent to the test set that the test set was able to decode but that contained errors.
• Reverse Erasures. The number of frames that the cdma2000 device sent to the test set but the test set was not able to decode.

Base Station Emulation

• Default SCH data pattern changed from fixed data pattern to PRBS

  Changing the pattern to PRBS improves the ability to accurately determine the spreading rate for the SCH since code domain measurements on SO32 calls can not determine the actual spread rate of the signal when using a fixed data pattern. The PRBS setting appears to be far more useful in a wider variety of test cases and so the default for this setting has been changed to the more useful case. See CALL:SCHannel:TDSOption:DSOurce and Configuring the TDSO Supplemental Channel Information .

• Mobile Station's ESN in decimal format

  The mobile station's ESN can be displayed in decimal format. See CALL:MS:REPorted:ESNumber[:DECimal]? and Performing a Registration .

• Status Request Query On/Off control

  During registration and call setup the test set will normally issue a series of status requests to obtain the band class, max EIRP, and other capabilities from the mobile station. These requests can be disabled in order to decrease the time required to establish a connection with the mobile station. See CALL:MS:REPorted:REQuest[:ENAble] and Paging IMSI Setup .

  Note that in most cases when the Status Requests are disabled, you must supply a value for MAX_EIRP in order for the test set and the mobile station to remain connected when the mobile station transmits near its maximum output power. See CALL:MS:REPorted:EIRPower:DEFault .

• Power up registration On/Off control

  The test set can disable requests for power-up registrations. See CALL:REGister:PUP[:STATe] and Setting Registration Parameters .

• Variable echo delay settings

  When the test set is connected to a mobile station in a voice echo mode the delay between the incoming voice and when that data is returned to the mobile station is adjustable. See CALL[:CELL[1]]:FCHannel[:FORWard]:SOURce:ECHO and Configuring the Forward Fundamental/Traffic Channel (F-FCH/Traffic) .

• Audio tones for digital voice services

  Pre-vocoded audio tones are available for selection as an audio source when a non loopback service option is connected. See CALL[:CELL[1]]:FCHannel[:FORWard]:SOURce and Configuring the Forward Fundamental/Traffic Channel (F-FCH/Traffic)

  The Spectrum Monitor measurement feature has been added. This allows you to find, identify and measure transmitted signals from your mobile phone. It can also be used for spur measurements in the transmit band. See Spectrum Monitor Description .

Base Station Emulation

• Mobile Station's ESN in decimal format

  The mobile station's ESN can be displayed in decimal format in the Mobile Station Information window. See CALL:MS:REPorted:ESNumber[:DECimal]? .

• Analog FM Demod

  The Audio Out connector on the test set's front panel can now be configured to carry one of two signals. It is normally configured to carry the output from the built in audio generator. It can now be configured to carry the analog FM Demod signal. When the analog FM signal is selected to route to the Audio Out connector, a fixed BW bandpass, expandor, and de-emphasis filters are available to operate on the demodulated signal. See SYSTem:AUDio and Configuring the Test Set's AUDIO OUT port .

Transmitter tests

• Front panel display graphics for Time Response of Open Loop Power Control (TIA/EIA-98-D 4.4.2 Time Response of Open Loop Power Control).

  This measurement is a graphic view of the mobile station under test's output power after a step increase or step decrease in cell power from the test set. The graph displays mobile station power over a 100 ms period with pass/fail results determined by the measured signal's conformance to mask limits derived from the test standard. See Time Response of Open Loop Power Control (TROLPC) Measurement Description .

• Code Domain Power code channel table

  The graphical code domain power measurement now includes a table of code channel power values that simplifies testing a mobile station's conformance to TIA/EIA-98-D 4.4.9.2.2 Code Channel Output Power for the Reverse Traffic Channel . The new table provides specific code channel power relative to the reverse pilot channel in units of dB. Also displayed in the table are Walsh number, spread factor, code channel power relative to mean output of the mobile station, and total code channel power relative to the mean output of the mobile station. See Waveform Quality/Code Domain Measurement Description .

• Adjustable limits on the Tx Spurious Emissions display (TIA/EIA-98-D 4.5.1 Conducted Spurious Emissions)

  The Tx Spurious Emissions measurement displays pass/fail results based on a mask defined by test standards. This mask automatically displays power limits derived from two adjacent frequency offsets and two alternate frequency offsets. An adjustable mask control feature is now provided that allows two mask parameters to be adjusted, one for the adjacent frequency pass/fail limits and one for the alternate frequency pass/fail limits. See Tx Spurious Emissions Measurement Description .

• Waveform Quality (rho) statistical measurement results (TIA/EIA-98-D 4.3.4 Waveform Quality and Frequency Accuracy)

  The Waveform Quality measurement Numeric Rho view is now displayed in a table when Multi-Measurement Count is on. Minimum, Maximum, and Average for the number of measurements requested is displayed in the table. Standard deviation is available using GPIB commands. See Waveform Quality/Code Domain Measurement Description and Statistical Measurement Results .

Transmitter tests

• Reverse Supplemental Channel (SO32 (+SCH))

  This implementation of TDSO service option 32 (SO32 (+SCH)) assigns the mobile station to both forward and reverse supplemental channels. There is no measurement selection or standard tests associated with the reverse supplemental channel.

  The implementation of TDSO service option 32 that was introduced at B.02 (SO32(+ F-SCH)) provided non-loopback frame error rate measurements on the forward supplemental channel. When SO32 (+SCH) is selected, frame error rate measurements on the forward supplemental channel are still available. See CALL[:CELL]:SOPTion[:SELected][:SELected] and TDSO Frame Error Rate Measurement Description .

• Front panel display graphics for Gated Power Rise/Fall measurements. (TIA/EIA-98-D test 4.4.7 Standby Output Power and Gated Output Power.)

  Beginning with release B.02 the graphical Gated Power measurement included a "Full" and "Zoom" view of the mobile station's signal during the gated on period. The gated power measurement now includes expanded views of the rising portion and falling portion of the mobile station's transmitter power during gated operation. Gated power occurs only when the mobile station is operating in IS-95 mode or IS-2000 mode with radio configuration 1 or 2 selected and eighth rate data is selected. See Gated Power Measurement Description .

     

  NOTE

  The Gated Output Power portion of this test is performed by the test set. The test set does not have capability to perform Standby Output Power.

Receiver Tests

• PRBS (Pseudo random bit sequence) for TDSO (service option 32) frame error rate tests.

  PRBS is an acronym for pseudo random bit sequence. PRBS is a new data pattern available for TDSO frame error rate tests. When making code domain measurements with a supplemental channel service option PRBS data is required. See CALL:SCHannel:TDSOption:DSOurce .

  When a test data service option is selected, the test set sends data bits to the mobile station on the forward supplemental channel. The mobile station demodulates the forward supplemental channel data and reports frame errors to the test set on the reverse fundamental channel. (See TDSO Frame Error Rate Measurement Description for additional details.)

Base Station Emulation

• Secondary 800 MHz Band

  Secondary 800 MHz Band (Band Class 10) has been added to the list of supported bands. See CALL:BAND and CALL:SETup:BAND:[:SELected] .

Transmitter tests

• Code Channel Timing and Phase (TIA/EIA-98-D test 4.3.2 Reverse Pilot Channel to Code Channel Time Tolerance, and 4.3.3 Reverse Pilot Channel to Code Channel Phase Tolerance)

  These tests assess any differences in timing or phase between active reverse code channels and the reverse pilot channel. (See Code Channel Time/Phase Error Measurement Description .)

• Gated Power (TIA/EIA-98-D test 4.4.7 Standby Output Power and Gated Output Power)

  This test (which is similar to the GSM power versus time measurement) verifies that mobile station transmitters conform to gated output power test limits. Transmitter output power is gated when operating in IS-95 or cdma2000 radio configuration one or two modes with partial (eighth) rate data selected. (See Gated Power Measurement Description .)

     

  NOTE

  The Gated Output Power portion of this test is performed by the test set. The test set does not have capability to perform Standby Output Power.

• Tx Spurious Emissions (TIA/EIA-98-D test 4.5.1 Conducted Spurious Emissions)

  This test provides a collection of signal energy measurements at only the alternate and adjacent frequency offsets specified by test standards to ensure that mobile stations do not transmit excessive signal energy outside of their transmit channels. (See Tx Spurious Emissions Measurement Description .) Measurements at 12.5

• Handoff Waveform Quality (performed at the explicit action time of the Universal Handoff Direction Message) (TIA/EIA-98-D test 4.3.4 Waveform Quality and Frequency Accuracy)

  This measurement has been added to provide a collection of waveform quality measurements acquired during mobile station transmission of a single code channel. This measurement can be performed only during a handoff, as specified in the TIA/EIA-98-D test standard. (See Handoff Waveform Quality Measurement Description .)

  The Handoff Waveform Quality measurement provides the same suite of measurement results as the multi-code waveform quality measurement (see Waveform Quality/Code Domain Measurement Description ), excluding EVM (Error Vector Magnitude) and code domain power measurements.

Receiver Tests

• Service Option 32 TDSO (F-SCH FER) (TIA/EIA-98-D test 3.4.1 Demodulation of Forward Traffic Channel with AWGN). Supports the following radio configurations:
  • Radio Configuration 3 (Forward 3, Reverse 3) at data rates from 9.6 to 153.6 kbps.
  • Radio Configuration 4 (Forward 4, Reverse 3) at data rates from 9.6 to 307.2 kbps.

  TDSO Frame Error Rate measurements provide a test of the mobile station receiver's ability to demodulate the forward supplemental channel. To obtain test results, the test set signals the mobile station under test to count errors that occur while the mobile station is demodulating fixed pattern data sent from the test set. Only convolutional encoding is supported. The test set then displays FER results received from the mobile station. (See TDSO Frame Error Rate Measurement Description .)

Base Station Emulation

• Intersystem Handoffs. The following handoffs between CDMA and AMPS systems can now be performed:
  • cdma2000 to AMPS.
    Handoffs to AMPS allow user-specified voice channel, transmit level, and SAT color code
  • cdma2000 to IS-95.
    Handoffs to IS-95 allow user-specified band, handoff channel, and IS-95 protocol. (Handoffs to IS-95 require the call to be in loopback service options SO2 or SO9 with full data rate selected.)
  • IS-95 to AMPS.
    Handoffs to AMPS allow user-specified voice channel, transmit level, and SAT color code.
