Chapter 3 — Using PowerXpert™ 3-1 Introduction This chapter provides information and instructions on using the Anritsu PowerXpert™ application, a data analysis and control software for use with Anritsu’s USB power sensors. PowerXpert provides a graphical user interface (GUI), making the PC appear like a traditional power meter that facilitates average power, time slot, and scope-like measurements.
3-2 3-2 Using PowerXpert™ PowerXpert Settings PowerXpert Settings PowerXpert always starts up in the default state of the connected sensor. Upon disconnection from PowerXpert, the power sensor resets and, after reconnection, restarts in the default state. Some features and settings offered by PowerXpert are only available with select power sensor models. Table 3-1.
Using PowerXpert™ Table 3-1.
PowerXpert™ Overview 3-3 Using PowerXpert™ PowerXpert™ Overview 3-3 PowerXpert’s graphical user interface layout is divided into eight sections as illustrated in Figure 3-1. Note that the screen for the MA24105A is shown in Figure 3-2. This numerical display is different in that it shows forward and reverse measurements.

Using PowerXpert™ 3-3 PowerXpert™ Overview Graticule Settings and Graphical Display Area This section provides a brief overview of the graticule settings and graphical display areas that are presented in the different operating modes of PowerXpert. The Power versus Time graph is used in all modes and provides the ability to plot measured power with respect to time (or time slots). This feature can be used for drift testing, tuning circuits, and for monitoring circuit behaviors to external stimuli.
3-3 PowerXpert™ Overview Using PowerXpert™ The following Power versus Time graph is used in “Time Slot Mode” and is available only with the MA24108A, MA24118A, and MA24126A power sensors. 7 2 6 4 5 1 3 Index Description Graticule Settings: 1 Number of Slots: Displays the current number of slots setting. This setting is changed via the “Time Slot Mode” settings area. Power Max (dBm): Sets the upper power level for the vertical scale.
Using PowerXpert™ 3-3 PowerXpert™ Overview The following Power versus Time graph is used in “Scope Mode” and is available only with the MA24108A, MA24118A, and MA24126A power sensors. 5 4 7 6 2 8 9 10 11 1 Index 3 Description Graticule Settings: Capture Time: Displays the current capture time setting. This setting is changed via the “Scope Mode” settings area. Power Max (dBm): Sets the upper power level for the vertical scale. Power Min (dBm): Sets the lower power level for the vertical scale.
3-4 Using PowerXpert™ Continuous Mode 3-4 Continuous Mode Continuous Mode is the default mode in which the PowerXpert starts and displays the average power of the input signal. In this mode, the sensor is “continuously triggered” and collects data at all times.
Using PowerXpert™ 3-4 Continuous Mode Forward Measurement Forward measurements listed below are available only with the MA24105A power sensor. Selectable forward measurement settings include: • Average Power • Crest Factor • Burst Average User • Peak Power • Burst Average Auto • CCDF Reverse Measurement Reverse measurements are available only with the MA24105A power sensor.
3-5 Using PowerXpert™ Time Slot Mode MA24108A, MA24118A, and MA24126A Power Sensors If external averaging is selected, two or more of these measurements are averaged together to form the displayed power. PowerXpert automatically uses a default aperture time based upon the connected sensor. For example, when using MA24118A with a 20 ms aperture time, the sensor collects 2860 samples (with ~142 KHz sampling rate), and averages them together to compute the measurement value.
Using PowerXpert™ 3-6 Scope Mode Slot Width Slot width is the width of each slot in milliseconds. All slots in a single frame should have exactly the same width. Start and End Exclusion Start exclusion is the time in milliseconds to be excluded from the beginning of each slot for power calculation. End exclusion is the time in milliseconds to be excluded at the end of each slot for power calculation.
3-6 Using PowerXpert™ Scope Mode Data Points Scope mode can be used to look at very fine structures of a signal. When using marker, gate, and fence, the power of any specific time can be accurately measured. To better observe these fine signal structures, a graph capture time can be reduced to get better resolution. However, as capture time shrinks, the time intervals between data points on the graph also decrease. The capture time can continue to shrink until it approaches the absolute resolution limit.
Using PowerXpert™ 3-6 1 Scope Mode 2 Data Points > 100 Data Points ≤ 100 3 Time Interval #2 Time Interval #3 Time Interval #1 Time Interval #2 Time Interval #3 Power (dBm) Time Interval #1 4 Time (ms) 5 Power data point plotted at the left end of the time interval Index 1 2 3 4 5 6 7 8 9 6 Time (ms) Note missing trace 7 at last time interval 8 Power data plotted as horizontal line across full time interval 9 Note step responses Description Data Points > 100 Data Points 100 Time Inte
3-6 Using PowerXpert™ Scope Mode Gate and Fence The Gate and Fence feature enables measurement of the desired portion of the waveform. A Gate is a specification for extracting an averaged power reading measurement between two defined points on a pulsed waveform. A fence must be set up within the boundaries of a gate, unless the fence is disabled by setting the Fence start and end to zero, or to the same value.
Using PowerXpert™ 3-7 General Settings Apply Above Settings Button The Apply above settings button applies all changes made to the “Scope Mode” settings. Changes to these settings do not take affect until clicking this button. 3-7 General Settings The PowerXpert general settings are common to all three modes and power sensors. 1 Must be clicked to Apply above settings Index 1 Description Button must be clicked to apply above settings Figure 3-14.
3-7 Using PowerXpert™ General Settings Auto Average Auto average is only available with the MA24108A, MA24118A, and MA24126A power sensors. Auto average sets the auto averaging status and count. When an auto averaging resolution is selected, the sensor chooses an averaging number that is a compromise between stabilizing the power reading and providing reasonable settling time. It does this by choosing an averaging number based on the power level currently being measured.
Using PowerXpert™ 3-7 General Settings Averages The Averages setting allows you to specify the number of measurements that are averaged to calculate the displayed power. A setting of 1 disables averaging. This setting is only available when “Auto Average” is Off. Offset A fixed value (in dB) specified by the user is applied as a power offset to the sensor. A positive offset adds a value to the power readings and can be used to compensate for attenuators, couplers, limiters, and other lossy devices.
3-8 3-8 Using PowerXpert™ Trigger Settings Trigger Settings Trigger settings are only available in Time Slot Mode and Scope Mode with power sensor models MA24108A, MA24118A, and MA24126A. Trigger is an event that initiates a measurement run. When the sensor is armed, it starts looking for the trigger. Once the trigger occurs, the sensor starts collecting data and measurement commences. Before arming the sensor, the sensor must be set up with the following trigger related parameters: Figure 3-17.
Using PowerXpert™ 3-8 Trigger Settings Trigger Level Sets the power level threshold of the waveform under test that, when crossed, triggers a measurement. It is used during internal triggering only. Trigger Edge It sets the trigger edge for internal and external trigger. Trigger edge can be set to positive or negative.
3-8 Using PowerXpert™ Trigger Settings Specifying a negative delay allows the user to display data occurring immediately before the trigger event. The negative delay cannot be greater than or equal to the capture time. If the capture time conflicts with the trigger delay, an error is generated. 1 2 3 Index Description 1 Capture Time (ms) 2 Trigger Level (dBm) and Positive Edge Trigger 3 Positive Trigger Delay Time (ms) Figure 3-19.
Using PowerXpert™ 3-9 3-9 Tools Tools The Tools menu provides the option of zeroing all sensors, capturing the PowerXpert screen display, enabling the log data and offset table features, and updating the sensor firmware. Figure 3-20. Tools Menu Zero All Sensors Zero All Sensors provides a convenient method of zeroing all connected sensors. Zero all sensors before making power measurements.
3-9 Using PowerXpert™ Tools Log Data The Log Data feature provides the ability to record data in a comma separated value file and is accessed from the Tools | Log Data toolbar. This feature is available only when the application is in Continuous Average mode. Data logging is set up in the dialog below: Figure 3-22.

3-9 Using PowerXpert™ Tools When using multiple sensors, the sensor parameters are applied to the selected sensor in the Sensor Information area. Figure 3-26.
Using PowerXpert™ 3-9 Tools Offset Table Offset Table feature is only available with the MA24104A and MA24106A power sensors. Offset table provides the ability to apply corrections to measurements when RF devices are used between the sensor and DUT. Offset Table is different from Fixed Offset as it provides the ability to enter different offset values at different frequencies for an RF device. The frequency response of that device needs to be known before it can be entered.
3-10 Using PowerXpert™ Settings 3-10 Settings The Settings menu is only available with the MA24108A, MA24118A, and MA24126A power sensors. The Settings menu provides for saving and recalling PowerXpert setups, resetting PowerXpert, setting the sensor time out, and enabling secure mode. Figure 3-29. Settings Menu Saving and Recalling Settings The current settings can be saved to any one of ten non-volatile storage locations.
Using PowerXpert™ 3-10 Settings During triggering (internal or external), the sensor sends the data to the application after it receives a trigger. If the PowerXpert application does not receive any data from the sensor for the set timeout period, then the user is informed and is prompted to re-arm the sensor. Figure 3-32. Trigger Timed Out Dialog If there is no response from the sensor after re-arming of the trigger, the PowerXpert application will display the “No sensor” message. Figure 3-33.
3-10 Using PowerXpert™ Settings Secure Mode The MA24104A and MA24106A USB power sensors have two different types of memory devices: • Non-Volatile 32 KB FLASH memory within the PIC18F4550 micro-controller.

Chapter 4 — Power Sensor Care 4-1 Introduction Anritsu Power Sensors are high quality precision laboratory instruments and should receive the same care and respect afforded such instruments. Follow the precautions listed below when handling or connecting these devices. Complying with these precautions will guarantee longer component life and less equipment downtime due to connector or device failure.
4-3 RF Connector Precautions Power Sensor Care Clean the Connectors The precise geometry that makes the RF component’s high performance possible can easily be disturbed by dirt and other contamination adhering to the connector interfaces. When not in use, keep the connectors covered. Connectors must be cleaned using a lint-free cotton swab that has been dampened with isopropyl alcohol (IPA). Refer to Section 4-6 “Connector Cleaning” on page 4-7 for specific details.
Power Sensor Care 4-4 4-4 Connection Techniques Connection Techniques Connection Procedure Table 4-1 lists the Anritsu Company torque wrench and open end wrench part numbers for connectors used on USB power sensors. Table 4-1. Connector Wrench Requirements – Torque Wrenches and Settings – Open End Wrenches Torque Wrench Model Number Torque Specification Open End Wrench K (2.92 mm) 01-201 8 lbf·in (0.90 N·m) 01-204 N 01-200 12 lbf·in (1.35 N·m) 01-202 Connector Type Connecting 1.
4-5 4-5 RF Connector Preventive Care Power Sensor Care RF Connector Preventive Care Most coax connectors are assembled into a system and forgotten, but some, especially on test equipment are used almost continuously. The care and cleaning of these connectors is critical to accurate and reliable performance. Remember that all connectors have a limited life time and usually a maximum connect/disconnect specification, typically about 5,000 connections.
Power Sensor Care 4-5 RF Connector Preventive Care Positive Pin Depth Positive pin depth can result in buckling of the fingers of the female center conductor or damage to the internal structure of a device due to the axial forces generated. Caution Never make a connection when any positive pin depth condition exists. Negative Pin Depth Negative pin depth can result in poor return loss, possibly unreliable connections, and could even cause breakdown under peak power conditions.
4-5 RF Connector Preventive Care Power Sensor Care Pin Depth Gauge Use an Anritsu Pin Depth Gauge or equivalent as shown in Figure 4-2 on page 4-6 to accurately measure pin depths. Based on RF components returned for repair, destructive pin depth of mating connectors is the major cause of failure in the field. When an RF component is mated with a connector having a destructive pin depth, damage will likely occur to the RF component connector.
Power Sensor Care 4-6 4-6 Connector Cleaning Connector Cleaning Connector interfaces should be kept clean and free of dirt and other debris. Clean connectors with lint-free cotton swabs. Isopropyl alcohol is the recommended solvent. Figure 4-3 on page 4-8 illustrates the cleaning procedures for male and female connectors. Note Most cotton swabs are too large to fit into the ends of the smaller connector types.
4-6 Connector Cleaning Power Sensor Care 3 ISOPROPYL ALCOHOL 2 WATER INDUSTRIAL SOLVENTS 1 4 Do NOT use Industrial Solvents or Water on connector. Use only Isopropyl Alcohol. Dampen only, DO NOT saturate. FEMALE MALE 5 Use only isopropyl alcohol and the proper size of cotton swab. Gently rotate the swab around the center pin being careful not to stress or bend the pin or you will damage the connector. 6 Do NOT put cotton swabs in at an angle, or you will damage the connectors.

To ensure the most accurate power measurement, the statistically-low peak signals should not exceed +30 dBm. For example, if a signal has an expected crest factor of 10 dB, then the highest average power measured should not exceed +20 dBm.
11-3 Measurement Considerations Using the MA24108A, MA24118A, and MA24126A Noise and Averaging When there is a need to achieve a required reading resolution, particularly at low power levels, averaging is often needed to reduce noise and steady the displayed power reading. Use the noise vs. resolution table in “Optimizing the Readings” on page 11-3 to determine the number of averages that will typically be required for a given resolution.
Using the MA24108A, MA24118A, and MA24126A 11-3 Measurement Considerations Noise and Time Resolution in Scope Mode In scope mode (and in all other modes) the MA24108A / MA24118A is sampling at full speed, which is about once every 7 µs. When the period chosen for scope mode exceeds the number of data points times this period, then multiple ADC samples are averaged to form each data point. Therefore there is a trade-off between time resolution (many data points) and trace noise.

Applying power exceeding the damage level shown on the label will damage the sensor’s sensing element resulting in impedance change. Input match will be degraded when element impedance is changed. If you suspect that a sensor is damaged, you should start with an input match pretest.

Chapter 13 — Remote Operation 13-1 Introduction This chapter describes the supported remote programming commands for each power sensor model.
13-2 Programming the Sensor Remote Operation Time Resolution The maximum time resolution of the sensor is 10 µs, hence all of the time arguments have a 10 µs resolution. This does not apply to the MA24105A sensor. Sampling Rate The MA24108A, MA24118A, and MA24126A sensors have two sampling rates. For “Continuous Mode” and Internal “Trigger Source”, the sensor has a sampling time of 6.8288 µs or a sampling frequency of 146.438 kHz. External “Trigger Source” has a sampling time of 7.

13-4 Mode Commands 13-4 Remote Operation Mode Commands The power sensor supports the following three modes of operation: • “Continuous Average Mode (CA Mode)” • “Slot Mode” • “Scope Mode” The power sensor starts up in the “Continuous Average Mode (CA Mode)” mode after the “START” command is issued and continuously reads power. The “CHMOD” command is issued to change the sensor’s mode of operation.
Remote Operation 13-4 Mode Commands Continuous Average Mode (CA Mode) CA mode is the default mode of operation. In CA mode, the sensor is continuously triggered and collects data at all times. Capture time is the only parameter associated with CA mode. The sensor calculates one average power averaged over the entire capture time. For example, for 20 ms of capture time, the sensor collects 2860 samples (with an approximate142 kHz sampling rate).
13-4 Mode Commands Remote Operation TSLTPARAMS Description: Sets all of the slot mode parameters. Syntax: TSLTPARAMS +LF Return Value: OK or ERR Remarks: The input parameters are comma separated values and must be sent in the correct order as follows: num1: Number of Slots num2: Slot Width num3: Start Exclusion Time num4: End Exclusion Time An asterisk “*” can be used instead of a value if the parameter is not to be changed.
Remote Operation 13-4 Mode Commands Scope Mode In scope mode, the sensor acts similarly to an oscilloscope in that it can be used to measure power as a function of time. Two parameters are needed to define the Scope mode operation: the collection period and the number of data points. In Scope mode, the sensor first waits for a trigger. Once a trigger is received, the sensor collects data at its sample rate of approximately 142 ksps for the duration of the capture time.
13-4 Mode Commands Remote Operation SCOPEPARAMS Description: Sets the scope mode parameters. Syntax: SCOPEPARAMS +LF Return Value: OK or ERR Remarks: The input parameters are comma separated values and must be sent in the correct order as follows: num1: Data Capture Time (maximum 300 ms) num2: Number of Points An asterisk “*” can be used instead of a value if the parameter is not to be changed.
Remote Operation 13-4 Mode Commands GATEPARAMS? Description: Gets the gate parameters. Syntax: GATEPARAMS? +LF Return Value: Comma separated string with the following four values: num1: Gate Start num2: Gate End num3: Fence Start num4: Fence End Compatible Sensor: MA24108A, MA24118A, MA24126A GENABLE Description: Enables or disables the gate.
13-5 13-5 Trigger Commands Remote Operation Trigger Commands Trigger is an event that initiates a measurement. When the sensor is armed, it waits for a trigger. Once the trigger occurs, the sensor starts data collection, calculation, and averaging to complete a measurement. Trigger commands must be sent after general setup of the power sensor as the general settings impact the trigger setup.
Remote Operation 13-5 Trigger Commands TRGSRC Description: Sets the trigger source. Syntax: TRGSRC +LF Return Value: OK or ERR Remarks: is an integer with the following values: 0 – Continuous 1 – Internal 2 – External Compatible Sensor: MA24108A, MA24118A, MA24126A TRGSRC? Description: Gets the trigger source.
Trigger Level Trigger level is the power value that triggers the sensor when it is crossed. This parameter has no effect in continuous, external or bus trigger setups. TRGLVL Description: Sets the trigger level in dBm. Syntax: TRGLVL +LF Return Value: OK or ERR Remarks: must be from –20 dBm to +20 dBm in 0.01 dB steps. Compatible Sensor: MA24108A, MA24118A, MA24126A TRGLVL? Description: Gets the trigger level in dBm.
Remote Operation 13-5 Trigger Commands Trigger Delay Trigger delay is the time in milliseconds between the trigger event and when the sensor starts taking readings. The trigger delay can be either positive or negative. The trigger delay can be set from –5 ms to 10,000 ms with a resolution of 0.01 ms. If the delay is negative, the sensor starts taking the readings before the trigger occurs and the total capture time includes the negative delay time.
13-5 Trigger Commands Remote Operation Trigger Noise Immunity When internally triggering on very noisy signals, the sensor can trigger at an undesired point or edge. To provide immunity against such situations, the sensor can be set to wait for N number of samples to cross the trigger level before it triggers. The value of N is the trigger noise immunity factor and is set by the “TRGNOISE” command, where N is a value from 1 to 10.
Remote Operation 13-5 Trigger Commands Trigger Arming The trigger parameters are effective only if the sensor is armed. Armed is the state when the sensor is waiting for a trigger. By default, the sensor is in Standby mode and must be armed before it can be triggered. “Trigger Arming” should be the last command sent to the sensor before triggering as any other type of command aborts the armed state and places the sensor in standby mode. When the sensor is armed, it waits for a trigger indefinitely.
13-5 Trigger Commands Remote Operation TRGARMTYP? Description: Gets the trigger arming state. Syntax: TRGARMTYP? +LF Return Value: An integer with the following values: 0 – “Auto Armed” 1 – “Single Armed” 2 – “Multiarmed” 3 – “Standby” Compatible Sensor: MA24108A, MA24118A, MA24126A 13-30 PN: 10585-00020 Rev.
