Page 59
Chapter 1, Introduction Theory of Operation Instrument Most of the Test Set’s internal oscillators and counters are phase-locked to the Frequency signal input from the rear-panel REF INPUT port. This signal is usually the output of the 10 MHz Oven Oscillator (A38) assembly, also available on the rear-panel. References The Reference Assembly (A27) is internally connected to the CDMA Reference (A29), which is connected to the external reference.
Page 60
FM signals are downconverted to a 700 kHz IF before demodulation. The demodulated signal is routed to the Audio Analyzer 1 (A35) (HP 8924E: FM assembly for audio frequency filtering. This assembly is also connected to the only) front-panel AUDIO IN connector for direct audio measurements.

Chapter 1, Introduction Theory of Operation • Controls the signal level out of the assembly using an Automatic Level Control (ALC) loop. The signal out of the Output assembly is now at the user-selected frequency, and contains any modulation that was selected (AM, FM, or CDMA), or is a continuous wave (CW) signal.
Page 64
Chapter 1, Introduction Theory of Operation RF and DUPLEX The Input assembly receives the signal from the output assembly and routes it to Outputs the selected output port: RF IN/OUT or DUPLEX OUT. The signal first goes to a variable attenuator for level control. If the DUPLEX OUT port is selected, the signal then goes directly to that port without additional attenuation.

Chapter 2, Troubleshooting Further Isolating RF Failures Further Isolating RF Failures Isolating failures in the RF assemblies of the Test Set can be difficult. One problem is that the RF Diagnostics sometimes use the built-in RF analyzer to test the built-in RF source, and vice versa. This is necessary to make the diagnostics self-contained, that is, they run without external equipment.
Page 97
Chapter 2, Troubleshooting Further Isolating RF Failures Isolating Input and Output Failures If all RF diagnostic tests pass, there could still be a problem with the input and output paths (including reverse-power and overpower protection). Run the Miscellaneous Diagnostics test titled RF Input Output Test. A failure indicates that the input section or front-panel connection is faulty.

Chapter 3, Repair Replacing the A16 Host Controller Replacing the A16 Host Controller RESTORING CALIBRATION DATA IN NEW A16 ASSEMBLIES Calibration data for the entire Test Set is stored in EEPROM U21 on the A16 Host Controller. When replacing the A16 Host Controller assembly, you must remove the Cal Data EEPROM from the old A16 assembly and insert it into the new assembly to preserve the calibration data for that instrument.
Page 136
Chapter 3, Repair Replacing the A16 Host Controller Switch S1 Settings The following table lists the factory default settings for the four-position DIP switch, S1. Note that the Write Protect function is set to allow calibration data to be entered when the automated periodic adjustments are made. To safeguard calibration data between periodic adjustments, set Switch 1 to the OPEN position.
Chapter 4, Periodic Adjustments Introduction Introduction Some assemblies, or combination of assemblies, require adjustments to compensate for variations in circuit performance over time. Periodic Adjustments are used to optimize Test Set performance by creating and storing new calibration factors to compensate for these changes. This operation is also referred to as “periodic calibration.”...
Chapter 4, Periodic Adjustments Introduction Manual and Automated Adjustments The Oven Oscillator (A38) frequency is the only manual adjustment made; the remaining adjustments are made automatically when the internal Periodic Calibration routines (PER_CAL3, CDMA_CAL, and PCB_CAL) are run, or when certain “zeroing” fields are selected on various screens. Any other manual adjustments must not be altered from their factory settings.
Chapter 4, Periodic Adjustments Introduction Calibration Equipment The manual 10 MHz Oven Timebase Adjustment requires a frequency counter that matches or exceeds the required accuracy for the tests performed by the Test Set. The automated Voltmeter References adjustment requires a DC voltmeter with ±0.015% accuracy.
Chapter 4, Periodic Adjustments Introduction Zeroing the DC_FM, DC Current, TX Power, and CDMA Power Functions These functions generate calibration offsets when selected. They are located on various Test Set screens because they are meant to be performed as a routine optimization procedure during normal instrument operation.
Chapter 4, Periodic Adjustments Introduction Running the Periodic Calibration Programs Press the TESTS key to access the TESTS (Main Menu) screen. Select the field. Select Procedure Location: Select from the : menu. Choices Select the field. Select Procedure Filename: Select from the : menu.
A write-protect switch on the controller assembly protects calibration data from corruption. The calibration procedures check the setting of the write-protect switch. If the switch is set to write-protect, a message is displayed: HP-IB . Change the switch setting as shown in Error: Cal data is read only and re-run the procedure.
Chapter 4, Periodic Adjustments Introduction PER_CAL3 Routines Voltmeter References Instructions are displayed explaining how to measure the negative and positive references with an external voltmeter. The user is then required to key in the readings. If the readings are reasonable, the two values are downloaded. For the Test Set to meet published specifications, the external DC voltmeter must be 0.015% accurate.

Audio Input selected with return conductor grounded Variable Frequency Notch Filter The calibration factors for tuning the variable-frequency notch filter are determined: The input to the filter is set to 10 evenly-spaced frequencies between 300 and 10 000 Hz.
Chapter 4, Periodic Adjustments Introduction CDMA_CAL Routines I/Q Modulator The four DACs on the IQ Modulator assembly are adjusted to minimize the gain/ quadrature spurs (GQS) and the origin offset spurs (OOS) that are present in IQ modulation. Twelve adjustments are made between 500 to 1000 MHz. At each frequency, the Phase Quadrature DAC and the I Gain DAC are adjusted to minimize the gain/quadrature spur first, and then the I Offset DAC and the Q Offset DAC are adjusted to minimize the origin offset spur.
Chapter 4, Periodic Adjustments Introduction PCB_CAL Routine The levels of each I and Q signal into the IQ Modulator (A25) are equalized. Sixteen signals are generated on the Cell Site Analog (A8) assembly (eight I and eight Q), and two I and Q noise signals come from the CDMA Reference (A29) assembly.

Page 457
Chapter 11, Block Diagrams Section Details Section Details RF Input/Output RF Frequency Measurement Section The A5 Input assembly pre-scales the RF input frequency and sends it to the A37 Measurement assembly where it is counted. This measurement is used to automatically tune the local oscillator (LO) and to select the input RF filters.
Page 458
Chapter 11, Block Diagrams Section Details Input Gain Control The A4 High Power Attenuator reduces the level through the RF IN/OUT port by 4 dB (but does not affect the level into the ANTENNA IN port). Step attenuators in the A5 Input section are switched in and out, manually or automatically. This keeps the input level within an optimum range for the mixers, IF amplifiers, and detectors.
Page 460
Chapter 11, Block Diagrams Section Details Spectrum Analysis The LO on the A32 Spectrum Analyzer assembly is swept across the span by the (Optional on Controller. The LO starts sweeping when the oscilloscope circuits on the A37 8924E) Measurement assembly trigger the display sweep to start. As the LO sweeps, the spectrum analyzer filters and then amplifies the IF signal in a logarithmic detector so the signal voltage will be proportional to the log of power.

Chapter 11, Block Diagrams Section Details Marker The A16 Host Controller keeps track of the marker position set on the front panel and displays the time and level measured for that position. Time accuracy is the same as the frequency counter’s accuracy because the scope timing is derived from the A27 Reference assembly but it is limited by the resolution of the display.
Page 465
Chapter 11, Block Diagrams Section Details RF Generator Frequency Reference Generation Section The A38 Oven Oscillator provides a 10 MHz reference that is connected by an external jumper to the rear panel REF INPUT connector. This signal goes to the A29 CDMA Reference to generate the CDMA clock signals and provide the 10 MHz reference for the A27 Reference.

Chapter 11, Block Diagrams Section Details Level Control The A26 Output assembly has an automatic-level-control (ALC) loop that acts as − a vernier control of RF level between 2 and +9 dBm. A step attenuator in the A5 − − Input assembly takes the level down to 127 dBm ( 137 dBm at the RF IN/OUT...

Chapter 11, Block Diagrams Section Details Audio Generator Waveform Generation Section The A15 Signal Source and Analyzer gets frequency and waveshape information from the A16 Host Controller. Waveform values are calculated real-time by a digital waveform synthesis IC. The AFGen1 output is always a sine-wave. The AFGen2 output is a sine-wave unless one of the signaling encoder functions is selected from the front panel.
