Page 25: Zeroing And Calibrating The U2040 X-Series
The command used to auto-calibrate the U2040 X-Series is: CALibration[1]:AUTO ONCE It is recommended that you zero the U2040 X-Series before calibrating. CALibration[1][:ALL] allows you to perform calibration with a single command. This calibration consists of zeroing the U2040 X-Series.
Page 26: Making Measurements
The advantage of using the lower-level commands over the MEASure? query and CONFigure command is that they give you more precise control of the U2040 X-Series. As shown in Table 1-1, the CONFigure command presets various states in the U2040 X- Series.
Page 27 The parameter DEFault is used as a placeholder. The source list parameter is used to specify a measurement channel. The U2040 X-Series supports only one channel. Therefore, the only valid value is (@1). The expected power and resolution parameters are set to their default values, leaving them at their current settings.

The expected power level and resolution parameters are defaulted, leaving them at their current settings. specifies CALCulate subsystem specifies the channels for the difference measurement MEAS2:POW:AC:DIFF? DEF,DEF,(@1),(@1) Channel A – A Keysight U2040 X-Series Programming Guide...
Page 29 Channel A/A Using the CONFigure command When you execute this command, the U2040 X-Series presets the optimum settings for the requested configuration (like the MEASure? query). However, the measurement is not automatically started and you can change measurement parameters before making measurements.

Page 36 The advantage of using the lower-level commands over the CONFigure command is that they give you more precise control of the U2040 X-Series. As shown in Table 1-1, the CONFigure command presets various states in the U2040 X-Series. It may be likely that you do not want to preset these states.
Page 37: Using Frequency-Dependent Offset Tables
Note that when selected, frequency-dependent offset correction is IN ADDITION to any correction applied for sensor frequency response. The U2040 X-Series is capable of storing 10 frequency-dependent offset tables of 512 frequency points each.
Page 38 OFFSET 1 FREQ 2 OFFSET 2 Frequency-dependent offset used Frequency of the signal to make measurements. you want to measure Calculated by the sensor using linear interpolation. FREQ 512 OFFSET 512 Figure 1-1 Frequency-dependent offset tables Keysight U2040 X-Series Programming Guide...
Page 39 Offset 2 “ “ Frequency n Offset n 4 If required, rename the frequency-dependent offset table using MEMory:TABLe:MOVE <string>,<string>. The first <string> parameter identifies the existing table name, and the second identifies the new table name. Keysight U2040 X-Series Programming Guide...
Page 40 To list the frequency-dependent offset tables currently stored in the U2040 X-Series, use the following query: MEMory:CATalog:TABLe? The U2040 X-Series returns the data in the form of two numeric parameters and a string list representing all stored tables. <numeric_value>,<numeric_value>{,<string>} The first numeric parameter indicates the amount of memory, in bytes, used for storage of tables.
Page 41 Query which returns the frequencies stored in the frequency-dependent offset table (in Hz). MEMory:TABLe:GAIN[:MAGNitude]:POINts? Query which returns the number of offset factor points stored in the frequency-dependent offset table. MEMory:TABLe:GAIN[:MAGNitude]? Query which returns the offset factors stored in the frequency-dependent offset table. Keysight U2040 X-Series Programming Guide...
Page 42 –221, “Settings conflict” occurs. Making the measurement To make the power measurement, set the U2040 X-Series for the frequency of the signal you want to measure. The U2040 X-Series automatically sets the offset factor. Use either...
Page 43 U2040 X-Series uses the highest or lowest frequency point in the table to set the offset. – To find out the value of the offset being used by the U2040 X-Series to make a measurement, use the [:SENSe[1]:]CORRection:FDOFfset|GAIN4[:INPut][:MAGNitude]? query.
Page 44: Setting The Averaging
Chapter 16, "SENSe Subsystem". Averaging The U2040 X-Series has a digital filter to average power readings. The number of readings averaged can range from 1 to 1024. This filter is used to reduce noise, to obtain the desired resolution, and to reduce the jitter in the measurement results.

Page 47: Setting Offsets
Setting Offsets Channel offsets The U2040 X-Series can be configured to compensate for signal loss or gain in your test setup (for example, to compensate for the loss of a 10 dB attenuator). You use the SENSe command subsystem to configure the U2040 X-Series. Gain and loss corrections are a coupled system.

Page 49: Setting Measurement Limits
U2040 X-Series Remote Operation Setting Measurement Limits You can configure the U2040 X-Series to detect when a measurement is outside of a predefined upper and/or lower limit value. Limits can be applied to power, ratio, or difference measurements. Setting limits The U2040 X-Series can be configured to verify the power being measured against an upper and/or lower limit value.
Page 50 – Use the CALCulate[1]|2|3|4:LIMit:FAIL? and CALCulate[1]|2|3|4:LIMit:FCOunt? queries for limits. – Use the STATus command subsystem. If TRIGger:DELay:AUTO is set to ON, then the number of failures returned by NOTE CALCulate[1]|2|3|4:LIMit:FCOunt? is affected by the current filter settings. Keysight U2040 X-Series Programming Guide...
Page 51: Getting The Best Speed Performance
The U2040 X-Series has a very flexible triggering system. For simplicity, it can be described as having three modes: – Free Run: When the U2040 X-Series is in the Free Run mode, it continuously takes measurements. A measurement is in free run when INITiate:CONTinuous is set to ON and TRIGger:SOURce is set to IMMediate.
Page 52 U2040 X-Series Remote Operation – Single Shot: When the U2040 X-Series is in the Single Shot mode, it takes a new measurement when a trigger event is detected and then returns to the idle state. A measurement is in single shot when INITiate:CONTinuous is set to OFF. Note that a measurement can take several INT/EXT triggers depending on the filter settings.
Page 53 Units The U2040 X-Series can output results in either linear or log units. The internal units are linear, therefore optimal performance is achieved when the results output are also in linear units (since the overhead of performing a log function is removed).

Page 59: Table 1-3 Bit Definitions - Status Byte Register
The *STB? (status byte query) command is similar to a serial poll except it is processed like any other U2040 X-Series command. *STB? returns the same result as an IEEE-488 serial poll except that the request service bit (bit 6) is not cleared if a serial poll has occurred.
Page 60: Table 1-4 Bit Definitions - Standard Event Register
– send a *CLS (clear status) command. – query the event register using the *ESR? (event status register) query. The standard event enable register is cleared when you: – cycle the U2040 X-Series power. – execute a *ESE 0 command. Keysight U2040 X-Series Programming Guide...
Page 61: Table 1-5 Bit Definitions - Questionable Status Registers
The questionable status register provides information about the quality of the U2040 X-Series measurement results. Any or all of these conditions can be reported in the questionable data summary bit through the enable register. You must write a value using the STATus:QUEStionable:ENABle command to set the enable register mask.
Page 62: Table 1-7 Bit Definitions - Operation Status
U2040 X-Series Remote Operation Operation status The operation status group monitors conditions in the U2040 X-Series measurement process. The following bits in these registers are used by the U2040 X-Series: Table 1-7 Bit definitions - Operation status Bit number Decimal weight...

Page 64 The *OPC? and *OPC commands allow you to maintain synchronization between the computer and the U2040 X-Series. The *OPC? query places an ASCII character 1 into the U2040 X-Series output queue when all pending commands are completed. If your program reads this response before continuing program execution, you can ensure synchronization between one or more instruments and the computer.
Page 65: Saving And Recalling U2040 X-Series Configurations
U2040 X-Series Remote Operation Saving and Recalling U2040 X-Series Configurations To reduce repeated programming, up to 10 U2040 X-Series configurations can be stored in the U2040 X-Series non-volatile memory. The error list, remote addresses, frequency-dependent offset table data, and zeroing/calibration information are not stored.

Page 110: Calibration Subsystem
CALibration Subsystem CALibration Subsystem The CALibration command subsystem is used to zero and calibrate the U2040 X-Series. The numeric suffix of the CALibration command (CALibration1) refers to Channel A. Zeroing and calibration of the U2040 X-Series is recommended: – When a 5°C change in temperature occurs –...
Page 111: Calibration[1]:Auto
This command auto-calibrates channel A when enabled. When 1|ON is enabled, auto-calibration is updated every 10 minutes. 0|OFF can be set to disable auto-calibration. The query returns the calibration state. The U2040 X-Series should be zeroed before calibration using the NOTE CALibration:ZERO:AUTO ONCE command. Example...
Page 112: Calibration[1]:Zero:auto
Description This command causes the U2040 X-Series to perform its auto-zeroing routine when enabled. This adjusts the U2040 X-Series for a zero power reading with or without power supplied to the U2040 X-Series. When 1|ON is enabled, the zero is maintained by a combination of on-the-fly zero measurements and temperature compensation.
Page 113: Calibration[1]:Zero:type
CALibration[1]:ZERO:TYPe EXTernal|INTernal CALibration[1]:ZERO:TYPe? Description This command sets the U2040 X-Series to the external or internal zeroing mode. Upon power up, the U2040 X-Series defaults to the internal zeroing mode. This query returns the current zeroing mode of either INT or EXT.
Page 114: Calibration[1]:Zero:normal:auto
CALibration[1]:ZERO:NORMal:AUTO? Description This command provides a quick way of zeroing the NORMal path of the U2040 X-Series. This command causes the U2040 X-Series to perform its zeroing routine when ONCE is selected. This adjusts the U2040 X-Series for a zero power reading with or without power supplied to the U2040 X-Series.
Page 115: Calibration[1][:All]
Syntax CALibration[1][:ALL] CALibration[1][:ALL]? Description This command causes the U2040 X-Series to perform a calibration sequence which consists of: 1 Zeroing the U2040 X-Series (CALibration[1]:ZERO:AUTO ONCE), and 2 Calibrating the U2040 X-Series (CALibration[1]:AUTO ONCE). When the calibration sequence is completed, this query enters 0 or 1 into the output buffer to indicate if the sequence was successful.
