Applicable Models: All Reads or writes Measurement data, Memory data, or Normalization Divisor data from the Data Access Map location.
Equation Editor Notes:
Note: The Calc:Data SCORR command to read/write error terms is Superseded with SENS:CORR:CSET:DATA. SCORR commands do NOT accommodate greater than 12 error terms. |

Parameters |
||
<cnum> |
Channel number of the measurement (optional). |
|
<mnum> |
Measurement number for each measurement. |
|
<char> |
Formatted measurement data to or from Data Access Map location. Display (access point 2). Note: When querying FDATA, data is received in degrees. When setting phase using FDATA, the command expects the data in radians.
|
|
|
Complex measurement data. Writes data to Data Access Map location. Raw Measurement (access point 0). Note: Write access is forbidden on the standard channel if factory calibration is on (applies to ENA/PXI/Streamline, not to PNA); to disable factory calibration use SYST:FCOR:CHAN:COUP:STAT OFF command.
Reads data from Apply Error Terms (access point 1).

Parameters |
|
<cnum> |
Channel number of the measurement (optional). |
<mnum> |
Measurement number for each measurement. |
<bufferName> |
(string) – Name of the buffer to be read. Note: The following names assume a 2-port VNA. Also, by default, the parameter names assume that VNA Port 1 is connected to the DUT input and VNA Port 2 is connected to the DUT output. If the RF Path settings are changed from the default, the names will change accordingly. For example, if the VNA has 4 ports and Port 4 is connected to the DUT output, the names will change to "PIn1", "POut4", "S11", "S41", etc. Choose from: "POut2" - Power Out "PIn1" - Power In "MSig2" - Modulation Signal Out "MDist2" - Modulation Distortion Out "MGain21" - Modulation Gain "MComp21" - Modulation Compression "PGain21" - Power Gain "S11" - Linear Input Match "S21" - Linear Gain "LPin1" - Linear Power In "LPOut1" - Linear Reflected Power In "LPOut2" - Linear Power Out |

Query Syntax |
CALCulate<ch>:MEASure<mnum>:DATA:RAW? "<string>" |
Return Type |
|
Default |
Not Applicable |
Applicable Models: All (Read-only) Returns the list of raw parameters associated with the measurement <mnum>. These are the raw parameters that are actually used by the error correction; the <mnum> measurement may not strictly depend on all of those. For example, 2 port S-parameters. If the DUT has transmission, then changing raw S11 will modify the corrected S22. If transmission is negligible, S22 is unaffected. The list is returned as strings comma separated. For unratioed parameters, the source port separator is ‘_’ instead of ‘,’ to avoid confusion in tokenization. This command applies to a Standard channel only. Application channels will return an error. |

The behavior is UNDEFINED if the active measurement is a transmission parameter such as an S21. 2 (S2P) returns data for the four 2 port parameters associated with the current measurement. Default. Data that is not available is zero-filled. 3 (S3P) returns data for the nine 3 port parameters associated with the current measurement. Data that is not available is zero-filled. 4 (S4P) returns data for the sixteen 4 port parameters associated with the current measurement. Data that is not available is zero-filled.
