Corrections are set to that same Transducer unit. Note that the legacy term
“Antenna Unit” is still used in the correction file, even though the more modern term
“Transducer Unit” is used in the user interface.
Similarly, the Bias rows can only be used in Correction register 1, because there can
only be one setting for Bias at any given time. If a Correction file with a Bias or Bias
State row is loaded into any Correction register but 1, an error is generated: Mass
storage error; Can only load Bias Settings into Correction 1
The data follows the DATA row, as comma separated X, Y pairs; one pair per line.
For example, suppose you have an Antenna to correct for on an N9020A version
A.02.06 and the correction data is:
–
0dB at 200MHz
–
17dB at 210MHz
–
14.8dB at 225MHz
Then the file will look like:
–
Amplitude Correction
–
"Correction Factors for 11966E"
–
"Class B Radiated"
–
A.02.06,N9020A
–
P13 EA3 UK6,01
–
Frequency Unit, MHz
–
Antenna Unit, dBuV/m
–
Frequency Interpolation, Linear
–

–
200.000000,0.00
–
210.000000,17.00
–
225.000000,14.80
The choices for the 1 of N fields in the metadata are as follows:
–
Frequency Unit: Hz, kHz, MHz, GHz
–
Antenna Unit: dBuV/m, dBuA/m, dBG, dBpT, None
