GPIB Command Reference

INPUCALC{1-3}

Syntax INPUCALC{1|2|3} <numeric 1>,<numeric 2>,..,<numeric NOP×2-1>,<numeric NOP×2>

Description Enters OPEN/SHORT/LOAD data for user calibration. Use the “INPUCALC1” command

to enter OPEN data (G-B); the “INPUCALC2” command, SHORT data (R-X); the

“INPUCALC3” command, LOAD data (R-X). When all the OPEN/SHORT/LOAD data is

entered, the calibration coefficient is automatically calculated and it is stored into the

non-volatile memory (backup memory). To use entered data, you are required to enter all

the data.

Enter data after setting the standard values, because the standard values to be used in

measuring data is needed to calculate user calibration coefficients.

A mismatch, between the number of required data at the execution of the command

(defined by the measurement point setting for user calibration data (set with the

“CALP”

command on page 275) and the number-of-points setting) and the number of entered

parameters, causes an error and the command is ignored. (No query)

Parameters

Total of NOP×2 parameters are required because each measurement point value (complex

number) is divided into 2 parameters for its real part and imaginary part. Where, NOP is

the number of points (for user measurement points) or 100 (for fixed measurement points),

and n is an integer between 1 and NOP.

Corresponding

key

No front panel key is available to execute this function.

Description

<numeric n×2-1> Real part of the calibration data value (complex number) for the n-th

measurement point

<numeric n×2> Imaginary part of the calibration data value (complex number) for

the n-th measurement point
