Attribute Summary:
Description:
With some measurements, you can select the unit for the Y- axis scale.
To select volts, send CALC:UNIT:VOLT 'V'.
2
To select volts , send CALC:UNIT:VOLT 'V2'. This is the default selection.
To select square root power spectral density, send CALC:UNIT:VOLT 'V/RTHZ'.
To select power spectral density, send CALC:UNIT:VOLT 'V2/HZ'.
To select energy spectral density, send CALC:UNIT:VOLT 'V2S/HZ'.
The trace specifier, CALCulate[1|2|3|4], determines which trace you are selecting. Omit the specifier or
send 1 for trace A, 2 for trace B, 3 for trace C, or 4 for trace D.
Depending upon the measurement data selection and specified trace coordinates, the selection of the base
unit may be restricted. In addition, the analyzer does not permit specification of the vertical unit for some
types of measurement data.
Table 6-7 indicates valid unit selections for the CALC:UNIT:VOLT command. If measurement data does
not appear in the table, you are not permitted to select the base unit. In this case, a query returns a null
string.
See "Determining Units" in Appendix E for information about available Y-axis units.
