R&S UPV-K9/-K91 Calibration The R&S CMW can be controlled via GPIB, LAN or USB. For remote control via LAN either CMW name ("CMW50050-", followed by the serial number) or IP address can be entered. The call between R&S CMW and UE should be established before running the clock synchronization.

Page 106 R&S UPV-K9/-K91 Measurements The sensitivity in dBV/Pa at each frequency is defined as the difference between the level at the network interface (digital level measured at the analog speech output of the system simulator) and the sound pressure level at the mouth reference point (MRP), and the sending loudness rating is calculated according to formula 5-1 of ITU-T P.79.

The measured sound pressure is either referenced to the ear reference point (ERP) or (from release 10) to DRP with diffuse field correction.

R&S UPV-K9/-K91 Measurements 5.6.2 Receiving Loudness Rating The receiving loudness rating (RLR) takes into account the absolute loudness in the receive direction and weights the spectral components in compliance with the difference between an average speech spectrum and the normal threshold of hearing in quiet of the average human ear.

Digital signal processing in the sidetone path can cause a delay of the sidetone, which would result in an annoying local echo in the handset or headset.
Page 114: Roundtrip Delay
R&S UPV-K9/-K91 Measurements Test signal is a composite source signal (CSS) according to ITU-T P.501, which consists of a voiced part and a pseudo-noise multisine part. Before the test, the test signal is offline-filtered according to the mouth speaker equalization curve obtained during mouth calibration.
Page 115 For this purpose, a remote control connection must be established between R&S UPV and R&S CMW500. See “CMW remote control” in the “Options” menu. The R&S UPV-K9 program controls the R&S CMW500 to start and stop the internal delay measurement, and queries the result for the internal processing delay via the remote control connection.

R&S UPV-K9/-K91 Measurements 5.11 Jitter Buffer Management Behaviour Release 14 of 3GPP TS 26.132 specifies a new test method “jitter buffer management behavior” which is a variant of the receiving impairment test (see Receiving Impairments). The jitter buffer management test determines delay and MOS-LQO versus time under the conditions of six realistic impairment profiles specified in 3GPP TS 26.132.
Page 119: Echo Loss (Tclw)
R&S UPV-K9/-K91 Measurements 5.12 Echo Loss (TCLw) The echo loss is the attenuation between the speech coder input and the speech decoder output (gain of speech coder + decoder = 1). Normally, the echo is caused by internal acoustic coupling between the telephone receiver and the microphone. Since the echo considerably reduces the sound transmission quality, it must not exceed a certain level.
Page 120: Stability Margin
R&S UPV-K9/-K91 Measurements 3GPP TS 26.131 specifies an echo loss of at least 46 dB; mobile phones with good echo cancellers can meet this requirement. Since the microphone of the mobile phone under test also picks up any side noise and treats it like an echo, it is essential that the test chamber is well shielded against external noise.
Page 121: Stability Loss
R&S UPV-K9/-K91 Measurements 5.14 Stability Loss From release 10 of 3GPP TS 26.132, the stability margin test case is replaced by a stability loss test case. The test measured the attenuation between input and output of the system simulator, similar to the echo loss measurement. Other than with the echo loss measurement, the result is not integrated over frequency, but the spectral minimum is searched.
Page 122: Echo Control Characteristics
R&S UPV-K9/-K91 Measurements Figure 5-19: Window of stability loss test A second measurement is performed without test signal to show the noise “floor” of the measurement. As the graph plots the path loss, the noise-induced result will usually be above the stability loss result.
Page 123 R&S UPV-K9/-K91 Measurements The test method measures the duration of any level difference between the sending signal of a double-talk sequence (where the echo canceller has been exposed to simultaneous echo and near-end speech) and the sending signal of the same near-end speech only.
Page 124 R&S UPV-K9/-K91 Measurements For each category, the ratio of frames in this category to the total number of frames is given, as well as the average level difference. Figure 5-21: Result screen of the "Echo Control Characteristics" test Interpretation of the Results: A positive level difference means that the level of the signal sent by the mobile is higher with simultaneous downlink speech than without.
Page 125: Sending Distortion
R&S UPV-K9/-K91 Measurements 5.16 Sending Distortion The SINAD (signal to noise and distortion) ratio in the transmit path is measured as a function of the sound level. A pulsed sinusoidal tone with a pulse length of approx. 360 ms is used for the measurement.
Page 126 R&S UPV-K9/-K91 Measurements Figure 5-22: Sending distortion measurement For tests in WB-AMR mode starting from release 8 of 3GPP TS 26.131 and TS 26.132, additional measurements are performed at the frequencies of 315 Hz, 408 Hz, 510 Hz and 816 Hz with a SPL of -4.7 dBPa at the MRP. Other than in the previous version of the test, the levels are not defined relative to ARL, but as absolute SPL at the MRP.

Alternatively, an activation signal specified by the terminal manufacturer may be used. Update key UPV-K9101 or UPV-K9102 is required for this version of the distortion test.
Page 128 R&S UPV-K9/-K91 Measurements For the sending direction, the activation signal must be pre-equalized according to the inverse frequency response of the artificial mouth. This can be done during import of the wav file. After a re-calibration of the artificial mouth, the equalization has become obsolete and has to be re-done.

R&S UPV-K9/-K91 Measurements 5.17 Receiving Distortion The SINAD (signal to noise and distortion) ratio in the receiving path is measured as a function of the acoustic signal level. A pulsed sinusoidal tone is used for the measurement. For tests according to up to release 8 (narrowband) and up to release 7 (wideband), the frequency of the tone is 1015 Hz.
