Generators 3 System Overview This chapter provides an overview of the capabilities of the R&S CMW500 and their use. 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 68: Rf Path Settings (Generators)
3.1.2 RF Path Settings (Generators) The R&S CMW500 provides a number of settings that are very similar in different gen- erators but can be configured independently. These settings control the routing of signals and the generator level.

(ON/OFF or RESTART/STOP). 3.2.2 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.
Page 71 (gain). 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. Frequency-dependent correction tables are administrated and activated/deactivated only via remote commands (...:FDCorrection:...).
Page 72: Statistical Settings
Measurements generally cover a basic time interval and can be repeated periodically. The measurement interval depends on the measurement context. The number of measurement intervals that the R&S CMW500 repeats in order to calcu- late statistical results is termed "statistic count" or "statistic length" (multi-measurement count).
Page 73: Statistical Results
3.2.4.1 Statistics Type The statistics type defines how the R&S CMW500 calculates the displayed values if the measurement extends over several measurement intervals. Assume that a trace or a bar graph contains a series of different measurement points. After n consecutive measure-...
Page 74 The statistics type of the displayed trace generally belongs to the display configuration settings in the measurement configuration dialogs. For single measurement results, the R&S CMW500 often displays a table with all statistics types. The statistics type is often combined with detector settings.
Page 75 ® System Overview R&S CMW500 Measurements ● Minimum: The displayed result represents the minimum value in a specified mea- surement interval. Narrow peaks cannot be smoothed out due to averaging. ● Maximum: The displayed result represents the maximum value in a specified mea- surement interval.
Page 76 Equation 1: To obtain average traces, the R&S CMW500 calculates the average of consecutive mea- surement intervals at each trace point. The formula above is modified for the magnitude error and the phase error, where positive and negative contributions tend to compensate each other.
Page 77: Limit Check
A limit check consists of comparing the measurement results to the limits and displaying a pass/fail indication. The R&S CMW500 provides different tools for viewing limits and limit check results. ● Limit lines show the upper, lower, or symmetric limits for a series of measurement results (measurement trace).
Page 78: Measurement Triggers
● The meaning of a "Free Run" trigger is measurement-specific. In most cases, a "Free Run" measurement is not related to any trigger events: The R&S CMW500 measures as fast as possible. However, there are exceptions (e.g. WCDMA measurements) where "Free Run" trigger implies a synchronization to the RF input signal.
Page 79: Tx Measurements
● The "Trigger Threshold" defines the power of the trigger signal where the R&S CMW500 generates a trigger event. Trigger signals below the trigger threshold are ignored by the trigger system. This trigger parameter is used for power trigger sources.
Page 80 The modulation parameters are acquired in a single measurement process. The calcu- lation is based on the comparison of the actual output signal Z of the transmitter under test with a reference signal R that is generated by the R&S CMW500 and represents an ideal error-free received signal.

Page 82 ® 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 83 The I/Q imbalance in dB is equal to the difference between the estimated I and Q ampli- tudes of the measured signal, which are normalized and logarithmized as follows: From the I/Q imbalance the R&S CMW500 derives the gain imbalance and quadrature mismatch as described in section "Measurement Results" in the description of the "WiMAX measurement"...
Page 84 ACLR definition for networks like GSM and TDMA but differs from the sign convention for WCDMA (3GPP/FDD); see specification 3GPP TS 34.121. To make results comparable, the R&S CMW500 uses the GSM sign convention for all network standards.
Page 85 ® 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 86 ® 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.
Page 87 3.2.7.6 Multi Evaluation Measurements In a multi evaluation measurement, the R&S CMW500 acquires a wide range of mea- surement results at once. For example, the GSM multi evaluation measurement provides the most important GSM mobile transmitter test results described in specification 3GPP TS 51.010: ●...
Page 88: Rx Measurements
The purpose of an RX measurement is to assess the performance of an RF receiver. The R&S CMW500 transmits a definite bit pattern on the downlink (forward) RF signal. The device under test demodulates the received signals; the percentage of bits or data blocks received in error is counted.
Page 89: Markers
Signaling applications provide integrated receiver quality tests. The receiver quality is assessed with an established network connection; the details are network-depend- ent. The R&S CMW500 controls the DUT such that it can either loop back the received data or send acknowledge (ACK) or not acknowledge (NACK) messages to indicate whether it could successfully receive a data packet or frame.

Thus the contents of the register parts can be processed by the controller as positive integer. The sum bit is obtained from the EVENt and ENABle part for each register. The result is then entered into a bit of the CONDition part of the higher-order register.
Page 185: Contents Of The Status Registers
® Remote Control R&S CMW500 Status Reporting System ● NTR bit = 1: the EVENt bit is set. ● NTR bit = 0: the EVENt bit is not set. This part can be overwritten and read at will. Reading the PTRansition register is non- destructive.

Page 192: Application Of The Status Reporting System
The STATus:QUEStionable register indicates whether the data currently being acquired is of questionable quality. The R&S CMW500 does not use the STATus:QUEStionable register. 5.6.4 Application of the Status Reporting System The purpose of the status reporting system is to monitor the status of one or several devices in a measuring system.
Page 193 ® Remote Control R&S CMW500 Status Reporting System The ENABle parts of the status registers can be set such that arbitrary bits in an arbitrary status register initiate an SRQ. To use the possibilities of the service request effectively, all bits in the enable registers SRE and ESE should be set to "1".

'RF_Settings1' 5.8 Response Buffers A response buffer is a region of memory in the R&S CMW500's RAM used to store device responses, in particular measurement data, which the R&S CMW500 generates while executing queries. If no buffer is enabled, a query in a remote script suspends program execution until the controller has retrieved the response.
Page 201: Buffer Contents And Buffer Commands
It is possible to define several buffers, however, only one buffer can be active at any time. When a response buffer is active, the complete contents of the R&S CMW500's output buffer are copied to the active buffer instead of being transferred over the remote inter- face.
