If you configure an invalid IP Address or an IP address that is used by another NOTE device or host, an error message is generated.
Power Meter Remote Operation Zeroing and Calibrating the P-Series Power Sensor P-Series wideband power sensor’s do not need manual calibration and zero routines performed. These are performed without removing the power sensor from the source. Zeroing Zeroing adjusts the power meter’s specified channel for a zero power reading. The command CALibration[1]|2:ZERO:AUTO [ONCE|ON|OFF|0|1] causes the power meter to perform its zeroing routine on the specified channel when enabled.
Page 60
Power Meter Remote Operation Calibration Sequence This feature allows you to perform a complete calibration sequence with a single query. The query is: CALibration[1|2][:ALL]? The query assumes that the power sensor is connected to the power reference oscillator. It turns the power reference oscillator on, then after calibrating, returns the power reference oscillator to the same state it was in prior to the command being received.
Power Meter Remote Operation Making Measurement The MEASure? and CONFigure commands provide a straight-forward method to program the power meter for measurements. You can select the measurement’s expected power level, resolution and with the N8262A the measurement type (that is single channel, difference or ratio measurements) all in one command. The power meter automatically presets other measurement parameters to default values as shown in Table 1-1...
Power Meter Remote Operation Using MEASure? The simplest way to program the power meter for measurements is by using the MEASure? query. However, this command does not offer much flexibility. When you execute the command, the power meter selects the best settings for the requested configuration and immediately performs the measurement.
Page 63
Power Meter Remote Operation Example 2 - Specifying the Source List Parameter The MEASure command has three optional parameters, an expected power value, a resolution and a source list. These parameters must be entered in the specified order. If parameters are omitted, they default from the right. The parameter DEFault is used as a place holder.
Page 64
Power Meter Remote Operation Example 4 - Specifying the Resolution Parameter The previous examples detailed the use of the expected value and source list parameters. The resolution parameter is used to set the resolution of the specified window. This parameter does not affect the resolution of the data, however it does affect the auto averaging setting (refer to Figure 1-2).
Page 65
Power Meter Remote Operation Example 6 - Making a Ratio Measurement The following command is performed on the N8262A. It queries the upper window to make a ratio measurement of Channel A/B. The expected power and resolution parameters are defaulted, leaving them at their current settings. specifies the relationship of the specifies window channels in the ratio...

Power Meter Remote Operation Using the CONFigure Command When you execute this command, the power meter 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 68
Power Meter Remote Operation Example 1 - The Simplest Method The following program segments show the simplest method of querying the upper and lower window’s measurement results respectively. Using READ? Reset instrument *RST Configure upper window -defaults to a Channel A measurement CONF1 Take upper window (Channel A) measurement READ1?
Page 69
Power Meter Remote Operation The following examples use the source list parameter to specify the measurement channel as Channel A. The expected power and resolution parameters are defaulted, leaving them at their current settings. The measurement is carried out on the upper window. Although the READ? and FETCh? queries have three optional parameters it is not necessary to define them as shown in these examples.
Page 70
Power Meter Remote Operation The following example uses the expected value parameter to specify a value of –50 dBm. This selects the power meter’s lower range (refer to “Range” on page 86 for details of the range breaks). The resolution parameter is defaulted, leaving it at its current setting.
Page 71
Power Meter Remote Operation Some fine tuning of measurements can be carried out using the CONFigure command and INITiate and FETCh? commands. For example, in the above program segment some fine tuning can be carried out by setting the filter length to 1024 and the trigger delay off.

Trigger with Delay This can be achieved using the same sequences above (apart from the second) with TRIG:DEL:AUTO set to ON.
Power Meter Remote Operation Output Format The power meter has two output formats for measurement results: ASCii and REAL. These formats are selected using the FORMat command. When FORMat is set to REAL, the returned result is in IEEE 754 floating-point format (note that the byte order can be changed using FORMat:BORDer) plus <LF>...
Power Meter Remote Operation Fast Mode In the highest speed setting, the limiting factor tends to be the speed of the controller being used to retrieve results from the power meter, and to a certain extent, the volume of remote traffic. The latter can be reduced using the FORMat REAL command to return results in binary format.

Power Meter Remote Operation Using Device Clear to Halt Measurements Device clear is an IEEE-488 low-level bus message which can be used to halt measurements in progress. Different programming languages and IEEE-488 interface cards provide access to this capability through their own unique commands.
Power Meter Remote Operation An Introduction to the SCPI Language Standard Commands for Programmable Instruments (SCPI) defines how you communicate with an instrument from a bus controller. The SCPI language uses a hierarchical structure similar to the file systems used by many bus controllers. The command tree is organized with root-level commands (also called subsystems) positioned at the top, with multiple levels below each root-level command.
Power Meter Remote Operation Using a Semicolon (;) Use a semicolon to separate two commands within the same command string. The semicolon does not change the present path specified. For example, the following two statements are equivalent. Note that in the first statement the first colon is optional but the third is compulsory.
Power Meter Remote Operation If you send two query commands without reading the response from the first, NOTE then attempt to read the second response, you may receive some data from the first response followed by the complete second response. To avoid this, do not send a query command without reading the response.
Power Meter Remote Operation SCPI Data Types The SCPI language defines different data formats for use in program messages and response messages. Instruments are flexible listeners and can accept commands and parameters in various formats. However, SCPI instruments are precise talkers. This means that SCPI instruments always respond to a particular query in a predefined, rigid format.

SENSe Subsystem [SENSe] Subsystem The SENSe command subsystem directly affects device specific settings used to make measurements. The SENSe subsystem is optional since this is the primary function of the power meter. The high level command CONFigure uses the SENSe commands to prepare the p ower meter for making measurements.
Page 346
SENSe Subsystem [SENSe[1]]|SENSe2:AVERage Commands These commands control the measurement averaging which is used to improve measurement accuracy. They combine successive measurements to produce a new composite result. The following commands are detailed in this section: [SENSe[1]]|SENSe2:AVERage:COUNt <numeric_value> [SENSe[1]]|SENSe2:AVERage:COUNt:AUTO <boolean> [SENSe[1]]|SENSe2:AVERage:SDETect <boolean> [SENSe[1]]|SENSe2:AVERage[:STATe] <boolean>...
Page 347
SENSe Subsystem [SENSe[1]]|SENSe2:AVERage:COUNt <numeric_value> This command is used to enter a value for the filter length.

TRIGger Subsystem TRIGger Subsystem The TRIGger subsystem is used to synchronize device actions with events. It includes the ABORt, INITiate and TRIGger commands. These are all at the root level in the command hierarchy but they are grouped here because of their close functional relationship.
TRIGger Subsystem ABORt[1]|2] This command removes the specified channel from the wait for trigger state and places it in the idle state. It does not affect any other settings of the trigger system. When the INITiate command is sent, the trigger system responds as it did before ABORt was executed.
TRIGger Subsystem INITiate Commands Initiate commands allow you to place the power meter in the wait for trigger state. The INITiate commands are overlapped, that is, the power meter can continue parsing and executing subsequent commands while initiated. Note that the pending operation flag is set, when the power meter enters an idle state and the flag is cleared when it re-enters the idle state.
TRIGger Subsystem INITiate[1]|2:CONTinuous <boolean> This command sets the power meter for either a single trigger cycle or continuous trigger cycles. A trigger cycle means that the power meter exits the wait for trigger state and starts a measurement. When entering local mode, if TRIGger[:SEQuence[1]|2]:SOURce is set to INT[[1]|2] or EXT, INITiate:CONTinuous is not changed.
TRIGger Subsystem Example This command places Channel B in the wait INIT2:CONT ON for trigger state. Reset Condition On reset (*RST), this command is set to OFF. On preset (SYSTem:PRESet) and instrument power-up, when entering local mode, if TRIGger[:SEQuence[1]|2]:SOURce is set to INT[[1]|2] or EXT, INITiate:CONTinuous is not changed.
TRIGger Subsystem INITiate[1]|2[:IMMediate] This command sets the power meter in the wait for trigger state. When a trigger is received, the measurement is taken and the result placed in the power meter memory. If TRIGger:SOURce is set to IMMediate the measurement begins as soon as INITiate:IMMediate is executed.
TRIGger Subsystem INITiate:CONTinuous:ALL <boolean> Sets all trigger sequences to be continuously initiated. If INITiate:CONTinuous:ALL is set to: – ON, trigger sequences are set to be continuously initiated – OFF, trigger sequences are not set to be continuously initiated Syntax Space INIT :CONT :ALL...
TRIGger Subsystem Query INITiate:CONTinuous:ALL? The query enters a 1 or 0 into the output buffer. – 1 is returned when trigger sequences are set to be continuous – 0 is returned when trigger sequences are not set to be continuous Query Example This command queries whether both INIT:CONT:ALL?
TRIGger Subsystem INITiate:CONTinuous:SEQuence[1]|2 <boolean> This command sets the power meter for either a single trigger cycle or continuous trigger cycles. A trigger cycle means that the power meter exits the wait for trigger state and starts a measurement. When entering local mode, INITiate:CONTinuous is set to ON.
TRIGger Subsystem Reset Condition On reset (*RST), this command is disabled. On preset (SYSTem:PRESet) and instrument power-up, this command is enabled. Query INITiate[1]|2:CONTinuous:SEQuence? The query enters a 1 or 0 into the output buffer. – 1 is returned when there is continuous triggering –...
TRIGger Subsystem INITiate[:IMMediate]:ALL This command initiates all trigger sequences. Syntax :IMM :ALL INIT Example This command initiates all trigger INIT:IMM:ALL sequences. Error Messages If the power meter is not in the idle state or INITiate:CONTinuous is ON, error –213, “INIT ignored” occurs. Keysight N8262A Programming Guide...
TRIGger Subsystem INITiate[:IMMediate]:SEQuence[1]|2 This command sets the power meter in the wait for trigger state. When a trigger is received, the measurement is taken and the result placed in the power meter memory. If TRIGger:SOURce is set to IMMediate the measurement begins as soon as INITiate:IMMediate is executed.
TRIGger Subsystem TRIGger Commands TRIGger commands control the behavior of the trigger system. The following commands are described in this section: TRIGger[1]|2:DELay:AUTO <boolean> TRIGger[1]|2:SOURce BUS|IMMediate|HOLD TRIGger[1]|2[:IMMediate] TRIGger[:SEQuence]:DELay <numeric_value> TRIGger[:SEQuence]:HOLDoff <numeric_value> TRIGger[:SEQuence]:HYSTeresis <numeric_value> TRIGger[:SEQuence]:LEVel <numeric_value> TRIGger[:SEQuence]:LEVel:AUTO <boolean> TRIGger[:SEQuence]:SLOPe <character_data> TRIGger[:SEQuence[1]|2]:COUNt <numeric_value> TRIGger[:SEQuence[1]|2]:DELay:AUTO <boolean>...
TRIGger Subsystem TRIGger[1]|2:DELay:AUTO <boolean> This command is used to determine whether or not there is a settling-time delay before a measurement is made. When this command is set to: – ON, the power meter inserts a settling-time delay before taking the requested measurement.
TRIGger Subsystem Example This command enables a delay on Channel A. TRIG:DEL:AUTO ON Reset Condition On reset, TRIGger:DELay:AUTO is set to ON. Query TRIGger:DELay:AUTO? The query enters a 1 or 0 into the output buffer indicating the status of TRIGger:DELay:AUTO. –...
TRIGger Subsystem TRIGger[1]|2[:IMMediate] This command causes a trigger to occur immediately, provided the specified channel is in the wait for trigger state. When this command is executed, the measurement result is stored in the power meter’s memory. Use FETCh? to place the measurement result in the output buffer.
TRIGger Subsystem TRIGger[1]|2:SOURce BUS|EXTernal|HOLD|IMMediate|INTernal[[1]|2] This command configures the trigger system to respond to the specified source. This command only selects the trigger source. Use the INITiate command to place the power meter in the wait for trigger state. This command has been included for compatibility purposes. It has the same NOTE purpose as TRIGger[:SEQuence[1]|2]:SOURce BUS|EXTernal|HOLD|IMMediate|INTernal[[1]|2] which should be used in...
TRIGger Subsystem Parameters Item Description/Defaul t Range of Values source – Available trigger sources: – BUS: the trigger source is the group execute trigger <GET> bus command, a *TRG EXTernal common command or the TRIGGER:IMMediate SCPI command. HOLDIMMediate INTernal[[1]|2] – EXTernal: the trigger source is the trigger input in the front panel. –...
TRIGger Subsystem Query TRIGger:SOURce? The query returns the current trigger source, either IMM, BUS or HOLD. Query Example This command queries Channel A’s trigger TRIG:SOUR? source. Error Messages – If the master is changed to IMM, BUS or HOLD, error –221 “Settings Conflict” occurs.
TRIGger Subsystem TRIGger[:SEQuence]:DELay <numeric_value> This command sets the delay between the recognition of a trigger event and the start of a measurement. Syntax numeric_value Space TRIG :SEQ :DEL Parameters Item Description/Defaul t Range of Values numeric_value The delay between the recognition of a trigger event and –1 to 1 second the start of the measurement.
TRIGger Subsystem Example This command sets a delay of 1 ms for TRIG:SEQ:DEL 0.001 Channel A. Reset Condition On reset, the trigger delay is set to 0 seconds. Query TRIGger[:SEQuence]:DELay? The query returns the current setting of the trigger delay. Query Example This command queries the trigger delay of TRIG:SEQ:DEL?
TRIGger Subsystem TRIGger[:SEQuence]:HOLDoff <numeric_value> This command sets the trigger holdoff in seconds. Syntax numeric_value :HOLD Space TRIG :SEQ Parameters Item Description/Defaul t Range of Values numeric_value The trigger holdoff in seconds. 1 µs to 0.4 seconds – DEF: the default value is 1 µs –...
