This includes a description of the basic concepts that the tester uses to organize, process and display measurement data. These basic concepts are valid for all firmware applica- tions.
Page 56: Two Sub-Instruments
® System Overview R&S CMW500 Sub-Instruments Depending on the installed baseband link option each firmware application instance can access an arbitrary RX and TX signal path or only a fixed signal path. The available baseband link options are the flexible link (R&S CMW-S550B/M) and the fixed link (R&S CMW-S550A).

Page 61: Connection Control (Measurements)
® System Overview R&S CMW500 Measurements 4.3.2 Connection Control (Measurements) The R&S CMW500 provides a number of settings that are very similar in different meas- urements but can be configured independently. These settings control the routing of input signals, the correction of the input power, the RF analyzer and trigger system. Signal Routing Settings (Input) The R&S CMW500 provides RF input connectors for different power ranges, see Connectors.
Page 62: Statistical Settings
® System Overview R&S CMW500 Measurements The external attenuation also enters into the internal calculation of the maximum input power that the R&S CMW500 can measure (see "Expected Nominal Power" below). Frequency-independent attenuations are defined as part of the measurement settings, refer to the description of the measurement application.
Page 63 ® System Overview R&S CMW500 Measurements Statistic Count / Measurement Cycle The statistic count (also termed statistic length) is the integer number of measurement intervals per measurement cycle (statistics cycle, single-shot measurement). The length of a measurement interval is measurement-specific. Conformance measurement speci- fications often request a certain number of repetitions of a particular measurement.
Page 64: Statistical Results
® System Overview R&S CMW500 Measurements 4.3.4 Statistical Results The R&S CMW500 repeats the measurements according to the selected statistic count and repetition mode; see Statistical Settings. Consecutive measurement values are stored and used to calculate statistical results. The following sections describe the cal- culation of statistical results in detail.
Page 65 ® System Overview R&S CMW500 Measurements The statistics type is often combined with detector settings, see Detectors. 4.3.4.2 Detectors The detector setting specifies how a single measurement result is calculated from a set of adjacent measurement points: ● RMS: The displayed result represents the RMS average (e.g. the mean power) in a specified measurement interval.
Page 66 ® System Overview R&S CMW500 Measurements 4.3.4.3 Peak Values "Peak" values are calculated as the maximum of the magnitude times the sign: ● For positive quantities such as the EVM, the peak value is equal to the maximum. ● For negative quantities such as the I/Q offset and the I/Q imbalance, expressed in dB, the peak value is equal to the minimum.
Page 67: Limit Check
® System Overview R&S CMW500 Measurements 4.3.4.5 Standard Deviation The "Standard Deviation" σ indicates the spread of the n values at each measurement point. It is defined as the square root of the variance, which is the mean square of the deviation of the values from their own arithmetic mean.
Page 68: Measurement Triggers
® System Overview R&S CMW500 Measurements The following example shows the template for an 8PSK-modulated GSM burst: To pass the limit check all "Power vs. Time" results must be between the upper and the lower limit lines. Fig. 4-3: Example of limit lines (GSM) The pass/fail indication in the result tables have the following meaning.
Page 69 ® System Overview R&S CMW500 Measurements ● Real-time or ARB generators can generate marker signals, to be used for synchro- nization of a measurement; see Marker Signals. ● Signaling applications provide trigger events which are synchronized to their downlink (forward link) signals. Due to the known downlink/uplink timing of the mobile station under test, a signaling trigger is generally appropriate for TX measurements run in parallel.
Page 70: Tx Measurements
® System Overview R&S CMW500 Measurements 4.3.7 TX Measurements The purpose of a TX measurement is to assess the performance of an RF transmitter. Despite the differences in detail, TX measurements for different network standards have many properties in common. 4.3.7.1 Power Results Power measurements are essential, e.g.
Page 71 ® System Overview R&S CMW500 Measurements Error Vector Magnitude (EVM), Phase Error, Magnitude Error, Code Domain Error The error vector E = Z - R’ is calculated as an array at each sample in the measurement interval. From E and Z the following arrays can be calculated: | E | = | Z - R’...
Page 72 ® System Overview R&S CMW500 Measurements I/Q Offset, I/Q Imbalance, Waveform Quality The following figure is an idealized representation of the modulation errors where the effects of a pure origin offset (first diagram) and of a pure I/Q imbalance (second diagram) are completely disentangled.
Page 73 ® System Overview R&S CMW500 Measurements The I/Q offset in dB (or dBc, according to some network standards) is the logarithmic ratio of the I/Q offset vector (i.e. the estimated DC-offset of the measured signal) to the average offset-corrected signal vector: In the equation above, | Offset - corrected signal vector | denotes the magnitude of the offset-corrected signal vector that is RMS-averaged over all samples.
Page 74 ® System Overview R&S CMW500 Measurements The off-carrier power can be assessed by several complementary quantities: ● The Adjacent Channel Leakage power Ratio (ACLR) is the ratio of the power mea- sured in an adjacent channel (Adjacent Channel Power, ACP) to the transmitted car- rier power, expressed in dB.
Page 75 ® System Overview R&S CMW500 Measurements Occupied Bandwidth (OBW) For wideband and OFDM(A) signals, the "Occupied Bandwidth" is the width of a sym- metric frequency interval around the nominal RF carrier frequency that contains 99 % of the total integrated power of the transmitted spectrum. The occupied bandwidth shows whether the signal is confined to the assigned bandwidth of the channel.
Page 76 ® System Overview R&S CMW500 Measurements In the following figure, the CDP of the DPCCH and the DPDCH in an uplink WCDMA signal is displayed over a measurement period of 120 WCDMA slots. The average DPDCH power is approximately 1 dB above the average DPCCH power. 4.3.7.5 I/Q Constellation Diagram The constellation diagram shows the modulation symbols as points in the I/Q plane.
Page 77 ® System Overview R&S CMW500 Measurements The constellation diagrams depend on the modulation type; for details refer to the description of the individual firmware applications. The diagrams are normalized such that the average distance of all points from the origin is 1. Constellation diagrams give a graphical representation of the signal quality and can help to reveal typical modulation errors causing signal distortions, as shown in the table below.

® System Overview R&S CMW500 Measurements bed in section "Measurement Results" in the description of the "WiMAX measurement" firmware application. Compared to independent TX measurements, multi evaluation measurements provide several advantages: ● They ensure highest measurement speed. ● They provide a comprehensive picture of the performance of a tested RF transmitter with a minimum of effort for configuring the R&S CMW500.
Page 79: Signaling Applications
® System Overview R&S CMW500 Signaling Applications ● In a single-ended receiver quality test, the received bit sequence is evaluated at the DUT. The measurement requires a real-time or ARB RF generator; no R&S CMW500 measurement application is needed. ● In a loop test the DUT is commanded into an operating mode where it loops back the received data.

Usually this service request causes an interrupt, to which the control program can react appropriately. It is also possible to wait until an SRQ is generated, see *SRQ? in chapter 7.1, "Common Commands", on page 193).
