CALCulate Subsystem

This subsystem is used to perform post-acquisition data processing. In effect, the collection of new data triggers the CALCulate subsystem. In this instrument, the primary functions in this subsystem are markers and limits.

Adjacent Channel Power Limit Test

:CALCulate:ACP:LIMit:STATe OFF|ON|0|1 :CALCulate:ACP:LIMit:STATe?

Turn limit test on or off. Factory Preset

and *RST: On Remarks: You must be in Basic, cdmaOne, iDEN mode to use this

command. Use INSTrument:SELect to set the mode.

Query the Current Measurement Status

:CALCulate:CLIMits:FAIL?

Checks if the current measurement is outside its limits. It returns a 0 (zero) if it is passing or a 1 (one) if it is failing.

Front Panel Access: None

Data Query

:CALCulate:DATA[n]?

Returns the designated measurement data for the currently selected measurement and sub-opcode.

n = any valid sub-opcode for the current measurement. See the

“MEASure Group of Commands” on page 25 for information on the data

that can be returned for each measurement.

Calculate/Compress Trace Data Query

Chapter 1 7

cdmaOne Programming Commands

CALCulate Subsystem

{,<soffset>}{,<length>}{,<roffset>}

Returns the designated trace data for the currently selected measurement. The command can be used with sub-opcodes (n) for measurement results that are trace data. See the following table.

This command is used to compress/decimate a long trace to extract the desired data and only return to the computer the necessary data. A typical example would be to acquire N bursts of GSM data and return the mean power of each burst.

The command can also be used to identify the best curve ﬁt for the data.

Curve Fit - applies curve ﬁtting routines to the data. Where <soffset> and <length> are required, and <roffset> is an optional parameter for the desired order of the curve equation. The query will return the following values: the x-offset (in points) and the curve coefﬁcients ((order + 1) values).

<Start offset> - is an optional integer. It speciﬁes the amount of data, at the beginning of the trace, that will be ignored before the decimation process starts. It is an integer index (that starts counting at zero) for all the elements in the trace. The default value is zero.

<Length> - is an optional integer that deﬁnes how many trace elements will be compressed into one value. This parameter has a default value equal to the current trace length.

<Repeat offset> - is an optional real number.It deﬁnes the beginning of the next ﬁeld of trace elements to be compressed. This is relative to the beginning of the previous ﬁeld. This parameter has a default value equal to the <length> variable. Select a number such that repeated additions will round to the correct starting index.

Example: To query the mean power of a set of GSM bursts:

1. Set the waveform measurement sweep time to acquire the required number of bursts.

2. Set the triggers such that acquisition happens at a known position relative to a burst.

3. Then query the mean burst levels using, CALC:DATA2:COMP? MEAN,62,1315,1442.3 (These parameter values correspond to GSM signals.)

Remarks: The optional parameters must be entered in the

speciﬁed order. If you want to specify <length>, you must also specify <soffset> or it’s default. (e.g.

CALC:DATA2:COMP? MEAN,62,1315

This command uses the data setting speciﬁed by the FORMat:DATA command and can return binary or ascii data.

cdmaOne Programming Commands

CALCulate Subsystem

Calculate Peaks of Trace Data

:CALCulate:DATA[n]:PEAKs? <threshold>,<excursion>[,AMPLitude|FREQuency|TIME]

Returns a list of peaks for the designated trace data n for the currently selected measurement. The peaks must meet the requirements of the peak threshold and excursion values.

The command can be used with sub-opcodes (n) for any measurement results that are trace data. See the table above. Subopcode n=0, raw trace data cannot be searched for peaks. Both real and complex traces can be searched, but complex traces are converted to magnitude in dBm.

Threshold - is the level below which trace data peaks are ignored Excursion - To be deﬁned as a peak, the signal must rise above the

threshold by a minimum amplitude change. Excursion is measured from the lowest point above the threshold (of the rising edge of the peak), to the highest signal point that begins the falling edge.

Amplitude - lists the peaks in order of descending amplitude, so the highest peak is listed ﬁrst. This is the default peak order listing if the optional parameter is not speciﬁed.

Frequency - lists the peaks in order of occurrence, left to right across the x-axis

Time - lists the peaks in order of occurrence, left to right across the x-axis

Example: Select the spectrum measurement.

Use CALC:DATA4:PEAK? -40,10,FREQ to identify the peaks above -40 dBm, with excursions of at least 10 dB, in order of increasing frequency.

Query Results: Returnsa list of ﬂoating-point numbers. The ﬁrst value

in the list is the number of peak points that follow. A peak point consists of two values: a peak amplitude followed by the its corresponding frequency (or time).

If no peaks are found the peak list will consist of only the number of peaks, (0).

The peak list is limited to 100 peaks. Peaks in excess of 100 are ignored.

Remarks: This command uses the data setting speciﬁed by the

FORMat:DATA command and can return real 32-bit, real 64-bit, or ASCII data. The default data format is ASCII.

CALCulate:MARKers Subsection

When using the marker commands you must specify the measurement in the SCPI command. We recommend that you use the marker commands only on the current measurement. Many marker commands will return invalid results, when used on a measurement that is not current. (This is true for commands that do more than simply setting or querying an instrument parameter.) No error is reported for these invalid results.

You must make sure that the measurement is completed before trying to query the marker value. Using the MEASure or READ command, before the marker command, forces the measurement to complete before allowing the next command to be executed.

Each measurement has its own instrument state for marker parameters. Therefore, if you exit the measurement, the marker settings in each measurement are saved and are then recalled when you change back to that measurement.

MEASure Group of Commands

This group includes commands used to make measurements and return results. The different commands can be used to provide ﬁne control of the overall measurement process. Most measurements should be done in single measurement mode, rather than doing the measurement continuously.

Each measurement sets the instrument state that is appropriate for that measurement. Other commands are available for each allow changing settings, view, limits, etc. Refer to:

SENSe:<measurement>, SENSe:CHANnel, SENSe:CORRection, SENSe:FREQuency, SENSe:POWer, SENSe:RADio, SENSe:SNYC CALCulate:<measurement>, CALCulate:CLIMits/DATA DISPlay:<measurement> TRIGger

Measure Commands

:MEASure:<measurement>[n]?

This is a fast single-command way to make a measurement using the factory default instrument settings. These are the settings and units that conform to the Standard.

• Stops the current measurement and sets up the instrument for the speciﬁed measurement using the factory defaults

• Initiates the data acquisition for the measurement

• Blocks other SCPI communication,waiting until the measurement is complete before returning results.

• After the data is valid it returns the scalar results, or the trace data, for the speciﬁed measurement.

If the optional [n] value is not included, or is set to 1, the scalar measurement results will be returned. If the [n] value is set to a value other than 1, the selected trace data results will be returned. See each command for details of what types of scalar results or trace data results are available. The binary data formats should be used for handling large blocks of data since they are smaller and faster then the ASCII format.

If you need to change some of the measurement parameters from the factory default settings you can set up the measurement with the CONFigure command. Use the commands in the SENSe:<measurement> and CALCulate:<measurement> subsystems to change the settings. Then you can use the READ? command, or the INITiate and FETCh? commands, to initiate the measurement and

26 Chapter1

query the results. See Figure 1-1. If you need to repeatedly make a given measurement with settings

other than the factory defaults, you can use the commands in the SENSe:<measurement> and CALCulate:<measurement> subsystems to set up the measurement. Then use the READ? command or INITiate and FETCh? commands, to initiate the measurement and query results.

Measurement settings persist if you initiate a different measurement and then return to a previous one. Use READ:<measurement>? if you want to use those persistent settings. If you want to go back to the default settings, use MEASure:<measurement>?.

Read Commands

:READ:<measurement>[n]?

• Does not preset the measurement to the factory defaults. (The MEASure? command does preset.) It uses the settings from the last measurement.

• Initiates the measurement and puts valid data into the output buffer. If a measurement other than the current one is speciﬁed, the instrument will switch to that measurement before it initiates the measurement and returns results.

• Blocks other SCPI communication,waiting until the measurement is complete before returning the results

If the optional [n] value is not included, or is set to 1, the scalar measurement results will be returned. If the [n] value is set to a value other than 1, the selected trace data results will be returned. See each command for details of what types of scalar results or trace data results are available.

It is performed at the decision points in the pilot waveform. If averaging is on, this is the average of the individual rms measurements.

2. Time offset (with units of seconds) is the time delay of the even second clock with respect to the start of the short code PN sequences, at offsets from the 15 zeros in the characteristic phase of the sequence.

3. Frequency error of the measured signal, with units of Hz. This is based on the linear best ﬁt of the uncorrected measured phase.

4. Carrier feedthrough has units of dB and is the dc error offset of I and Q, from the origin.

5. EVM has units of percent. The calculation is based on the composite of the phase error and magnitude error,between the measured signal and the ideal pilot channel. It is performed after the complimentary ﬁlter which removes the inter-symbol interference in the modulated data. If averaging is on, this is the average of the individual rms measurements.

6. Magnitude error (with units of percent) is the rms error between the measured (compensated) magnitude and the ideal magnitude. This is performed after the complimentary ﬁlter which removes the inter-symbol interference in the modulated data. If averaging is on, this is the average of the individual rms measurements.

7. Phase error (with units in percent) is the rms phase error between the measured phase and the ideal phase.The calculation is performed after the complimentary ﬁlter which removes the inter-symbol interference in the modulated data. If averaging is on, this is the average of the individual rms measurements.

Waveform (Time Domain) Measurement

This measures the power in your input signal with respect to time and is equivalent to zero-span operation in a traditional spectrum analyzer. You must select the appropriate mode using INSTrument:SELect, to use these commands.

The general functionality of CONFigure, FETCh, MEASure, and READ are described at the beginning of this section. See the SENSe:WAVeform commands for more measurement related commands.

Returns the following comma-separated scalar results:

1. Sample time is a ﬂoating point number representing the time between samples when using the trace queries (n=0,2,etc).

2. Mean power is the mean power (in dBm). This is either the power across the entire trace, or the power between markers if the markers are enabled. If averaging is on, the power is for the latest acquisition.

3. Mean power averaged is the power (in dBm) for N averages, if averaging is on. This is either the power across the entire trace, or the power between markers if the markers are enabled. If averaging is on, the power is for the latest acquisition. If averaging is off, the value of the mean power averaged is the same as the value of the mean power.

4. Number of samples is the number of data points in the captured signal. This number is useful when performing a query on the signal (i.e. when n=0,2,etc.).

5. Peak-to-mean ratio has units of dB. This is the ratio of the maximum signal level to the mean power. Valid values are only obtained with averaging turned off. If averaging is on, the peak-to-mean ratio is calculated using the highest peak value, rather than the displayed average peak value.

6. Maximum value is the maximum of the most recently acquired data (in dBm).

7. Minimum value is the minimum of the most recently acquired data (in dBm).

2 Returns comma-separated trace points of the entire captured trace data.

These data points are ﬂoating point numbers representing the power of the signal (in dBm). There are N data points, where N is the number of samples. The period between the samples is deﬁned by the sample time.

[:SENSe]:SPECtrum:ADC:RANGe?

Select the range for the gain-ranging that is done in front of the ADC. This is an advanced control that normally does not need to be changed. Auto peak ranging is the default for this measurement. If you are measuring a CW signal please see the description below.

• Auto - automatic range For FFT spectrums - auto ranging should not be not be used. An

exception to this would be if you know that your signal is “bursty”. Then you might use auto to maximize the time domain dynamic range as long as you are not very interested in the FFT data.

• Auto Peak - automatically peak the range ForCW signals, the default of auto-peak ranging can be used, but

a better FFT measurement of the signal can be made by selecting one of the manual ranges that are available: M6, P0 - P24. Auto peaking can cause the ADC range gain to move monotonically down during the data capture. This movement should have negligible effect on the FFT spectrum, but selecting a manual range removes this possibility. Note that if the CW signal being measured is close to the auto-ranging threshold, the noise ﬂoor may shift as much as 6 dB from sweep to sweep.

• Auto Peak Lock - automatically peak lock the range For CW signals, auto-peak lock ranging may be used. It will ﬁnd

the best ADC measurement range for this particular signal and will not move the range as auto-peak can. Note that if the CW signal being measured is close to the auto-ranging threshold, the noise ﬂoor may shift as much as 6 dB from sweep to sweep. For “bursty” signals, auto-peak lock ranging should not be used. The measurement will fail to operate, since the wrong (locked) ADC range will be chosen often and overloads will occur in the ADC.

• M6 - manually selects an ADC range that subtracts 6 dB of ﬁxed

gain across the range. Manual ranging is best for CW signals.

• P0 to 24 - manually selects ADC ranges that add 0 to 24 dB of ﬁxed

gain across the range. Manual ranging is best for CW signals.
