Page 30: Using This Chapter
Making Measurements Using This Chapter Using This Chapter Use this chapter to obtain an overview of how to operate the Agilent 8922M/S GSM Test Sets. This chapter is divided into the following sections: • Making Measurements • Agilent 8922M/S Operating Modes - explains how to configure the Agilent 8922M/S so that measurements can be made.
Page 31: Agilent Technologies 8922M/S Operating Modes
CW GENERATOR Active Cell The ﬁrst mode is the default mode and conﬁgures the Agilent 8922M/S as a GSM Base Station emulator. This allows calls to be made from the Agilent 8922M/S to the mobile phone and vice versa. Measurements can then be made to verify the mobile phone’s performance.
Page 32 Making Measurements Agilent Technologies 8922M/S Operating Modes To conﬁgure the Agilent 8922M/S to the desired operating mode, carry out the following instructions, referring to Figure 2-1 on page 4 for the position of the ﬁelds. • Ensure (1) is set to mobile phone type you require (GSM900, E-GSM, DCS1800, or PCS1900).
Page 33: Active Cell
Connect the mobile phone to the RF IN/OUT connector on the front panel of the Agilent 8922M/S. • Switch on the mobile phone and wait for it to camp to the Agilent 8922M/S (most mobile phones display 001-01 when the mobile phone has camped). •...
Page 34 Active Cell Mode Making a Call From To call (or page) the mobile phone from the Agilent 8922M/S, it is necessary for the the Agilent 8922M/S Agilent 8922M/S to know the number of the SIM in the mobile phone. [This number to the Mobile Phone is the International Mobile Subscriber Identity (IMSI).
Page 35 8922M/S and the mobile phone. For additional information on valid Absolute RF Channel Numbers (ARFCNs), consult the speciﬁcations in Chapter 3. TX Level This is a coded number used by the Agilent 8922M/S to command the mobile phone to transmit at a particular power. When the TX Level is changed, two things happen: •...
Page 36 The two most likely are that, either, the mobile phone is not operating correctly, or, there is some power loss between the Agilent 8922M/S RF IN/OUT connector and the mobile phone. If you suspect it is the second case, you can compensate the Agilent 8922M/S generator settings and measurement results for external losses or gains.
Page 37: Test Mode
Making Measurements TEST MODE TEST MODE To enter this mode, select TEST MODE as described in the section titled “Agilent 8922M/S Operating Modes”. In TEST MODE, the Agilent 8922M/S no longer controls the mobile phone. The TEST MODE is used when it is not desired, or not possible, to set up a call between the Agilent 8922M/S and the mobile phone.
Page 38 Making Measurements TEST MODE NOTE While the Test Mode is selected, the three MEASURE ON parameters are also available on the bottom right-hand side of all measurement screens. This provides control of the Expected Input parameters during measurements. Figure 2-3 Test Mode Mobile Phone To measure an incoming signal from the mobile phone’s transmitter, perform the...
Page 39 Broadcast Channel (BCH), by varying the BCH number and amplitude, (4), Using Test Mode see Figure 2-3 on page 2-10. TEST MODE provides the Agilent 8922M/S with a “forced” trafﬁc channel (TCH) generator which can be turned on and off without the need for any signaling or the presence of a mobile phone.
Page 40: Cw Generator
CW GENERATOR To enter this mode, select CW GENERATOR as described in the section titled “Agilent 8922M/S Operating Modes”. The CW Generator mode has the same measurement capabilities as the Test Mode but replaces the GSM BCH and forced TCH signals with a single unmodulated RF carrier. The frequency and amplitude of the Continuous Wave (CW) signal is controlled by the Channel, Amplitude, and the Frequency ﬁelds (1).
Page 41: Measurements
Making Measurements Measurements Measurements The measurements available on the Agilent 8922M/S can all be accessed from the cell control screen by selecting a measurement ﬁeld under MEASUREMENTS, (see Figure 2-5 on page 2-13) and pushing the knob. GSM Specific The measurements available are: Measurements •...
Page 42 Method The peak transmitter carrier power value is displayed on the cell control screen. After you have set up a call (Active Cell) or manually aligned the Agilent 8922M/S to the mobile phone (Test Mode/CW Generator), the Peak Power reading is displayed in the center of the screen (1).
Page 43 The measurement ﬁelds in this screen are RMS Phase Error, Peak Phase Error and Frequency Error (1), see Figure 2-7 on page 2-15. The Agilent 8922M/S input sensitivity (2) can be varied, if necessary, to ensure that the input signal level matches the Agilent 8922M/S RF Analyzer. Valid measurements are only made when the signal is within 3 dB of the RF Analyzer setting.
Page 44 Making Measurements Measurements These are: • PHASE ERR - this displays the phase error graphically. The phase error trace is displayed using an autoscaling phase error axis versus data bits (numbered 0 through 147). • DATA BITS - this screen allows you display a screen which details the values of the 148 bits in the timeslot (including midamble).
Page 45 12 time fields. You can choose your own time-positions, or use the default settings. The sensitivity of the Agilent 8922M/S receiver can be varied (3) allowing you to verify whether the input signal level matches the Agilent 8922M/S RF Analyzer.
Page 46 (1), see Figure 2-9 on page 2-18 • The sensitivity of the Agilent 8922M/S receiver can be varied (2) allowing you to verify whether the signal still falls within the boundaries of the GSM power mask.
Page 47 Data bits that are decoded are sent back to the Agilent 8922M/S. The Agilent 8922M/S compares them to original signal that was sent out and the differences are derived from this.
Page 48 Making Measurements Measurements By varying the Base station Amplitude ﬁeld (4), you can test the mobile phone’s receiver sensitivity. Actual results can be compared with the values reported by the radio. NOTE If the Base Station amplitude is lowered too much, the radio will lose the call. This will need to be re-established by increasing the base station amplitude, returning to the cell control screen, and originating the call before you can continue measurements.
Page 49 Making Measurements Measurements This sets the reference level to which the offset frequency values are compared. • Select Ramping or Modulation (3). • Set your Freq Offset value (4). Figure 2-11 Output RF Spectrum Measurements • The trace of the output RF spectrum can be viewed if you highlight View and select Trace (5).
Page 50 Making Measurements Measurements In the Agilent 8922, Output RF Spectrum measurements are made using a 3-pole synchronously tuned measurement ﬁlter. The measurement results will differ from measurements using a 5-pole ﬁlter. The difference between measurements of the “ideal” signals using a 3-pole ﬁlter and a 5-pole ﬁlter are shown in Table 1 and Table 2.

Screen set up, compatibility mode, radio type as well as other miscellaneous pieces of information are contained on this screen. To access this screen, highlight More and select CONFIG.
Page 68 Trigger Delay is not automatically restored. Example: In the Agilent 8922M/S, when using the RF Rise, a Trig- ger Delay of 0 is recommended. When changing from RF Rise to Ext Demod trigger mode, the default value of 473.4T should be re-entered for Trigger Delay.
Page 69 Making Measurements Advanced Features Power Ramp Setting The mobile transmitter output ramp should settle so that it complies with the power Time mask (GSM Rec 11.10) by the time output level calibration is done in the manufacturing process. The power mask is displayed in the Power Ramp screens. Peak Carrier Power measurement method is not made to GSM Rec.

HP/Agilent 8902A. • Low level signals from the Agilent 8922M/S must be very stable to be measured by the tuned RF level function of the HP/Agilent 8902A. The instrument timebases should be locked together. Also, if the Agilent 8922 source has unusually high residual FM it may cause the low level measurements to fail because the HP/Agilent 8902A cannot lock onto the signal.
Page 83 30 dB and 80 to 90 dB. Rise time and fall time for each of these is measured. When the Agilent 8922S is the UUT, the RF Generator is set to generate a pulsed GMSK signal. This signal is then analyzed with the UUT detector and oscilloscope.
Page 84 This signal is then analyzed by the UUT to assure that the frequency and phase errors are correct. If the UUT is an Agilent 8922S, clock and data signals are generated internally, and the HP/Agilent 8904A is not used.
Page 85 HP/Agilent 3456AVoltmeter Theory of the Test The HP/Agilent 8904A is used to generate accurate test signals which are analyzed by the UUT. The voltmeter is used to reduce measurement uncertainty by accurately characterizing the test signal level to predict the correct response of the UUT. The voltmeter is used in the AC level, DC level, SINAD and distortion measurements.
Page 86 The actual measurements are compared to the predicted to determine the accuracy of the UUT. The HP/Agilent 8904A is also used to create the 270.833 kHz clock signal and the pulse generator is used to create a random data pattern.
