This subsystem controls math scaling.
CALCulate:SCALe:REFerence:AUTO
Stores a relative value in the multimeter's dB Relative Register, which is used for the dB function in CALCulate:SCALe:FUNCtion. When the dB function is enabled, this value is subtracted from each voltage measurement after the measurement is converted to dBm.
Parameter | Typical Return |
---|---|
-200.0 dBm to +200.0 dBm. Default: 0. | +3.00000000E+02 |
Enable dB scaling with a -10 dB reference and a 300 Ω dBm reference resistance: CALC:SCAL:DBM:REF 300 |
Selects the reference resistance for converting voltage measurements to dBm. This reference value affects the dBm and dB scaling functions.
Parameter | Typical Return |
---|---|
50, 75, 93, 110, 124, 125, 135, 150, 250, 300, 500, 600, 800, 900, 1000, 1200 or 8000 Ω. Default: 600. | +3.00000000E+02 |
Enable dBm scaling with a reference resistance of 300 Ω: CALC:SCAL:DBM:REF 300 |
Selects the operation performed by the scaling function.
Parameter | Typical Return |
---|---|
{DB|DBM|PCT|SCALe} | DB, DBM, PCT, or SCALe |
Enable the DB scaling function referenced to the next measurement taken: CALC:SCAL:FUNC DB |
Stores a gain value M for the scaling function in CALCulate:SCALe:FUNCtion.
Parameter | Typical Return |
---|---|
-1.0E+15 to -1.0E-15, 0.0, +1.0E-15 to 1.0E+15. Default: 1.0. | +1.00000000E+02 |
Enable Mx-B scaling with a gain of 100 and an offset of 5. CALC:SCAL:FUNC SCAL |
Stores an offset value B for the scaling function in CALCulate:SCALe:FUNCtion.
Parameter | Typical Return |
---|---|
-1.0E+15 to -1.0E-15, 0.0, +1.0E-15 to 1.0E+15. Default: 0.0. | +5.00000000E+00 |
Enable Mx-B scaling with a gain of 100 and an offset of 5. CALC:SCAL:FUNC SCAL |
Stores a reference value for the PCT function in CALCulate:SCALe:FUNCtion.
Parameter | Typical Return |
---|---|
-1.0E+15 to -1.0E-15, 0.0, +1.0E-15 to 1.0E+15. Default: 0.0. | +3.00000000E+02 |
Enable PCT scaling with a 100V reference. CALC:SCAL:REF 100 |
Enables or disables automatic reference selection for the dB scaling functions.
Parameter | Typical Return |
---|---|
{ON|1|OFF|0}. Default: ON. | 0 (OFF) or 1 (ON) |
Enable the DB function with automatic reference selection and use the first measurement as the reference value: CALC:SCAL:DBM:REF 50 CALC:SCAL:FUNC DB CALC:SCAL:REF:AUTO ON CALC:SCAL:STAT ON READ? |
- For the dB scaling function, the first measurement is converted to dBm, and CALCulate:SCALe:DB:REFerence is set to the result.
- For the PCT scaling function, CALCulate:SCALe:REFerence is set to the first measurement.
Enables or disables the scaling function.
Parameter | Typical Return |
---|---|
{ON|1|OFF|0}. Default: OFF. | 0 (OFF) or 1 (ON) |
Enable the DB function with automatic reference selection and use the first measurement as the reference value: CALC:SCAL:DBM:REF 50 CALC:SCAL:FUNC DB CALC:SCAL:REF:AUTO ON CALC:SCAL:STAT ON READ? |
Allows you to specify the custom label of up to four characters (for example, RPM or °C) for scaled measurements.
Parameter | Typical Return |
---|---|
<quoted_string> A quoted ASCII string of up to four characters. | "RPM" |
Enable scaling with a gain of 100 and an offset of 5, and display "PSI" with measurements on the front panel. CALC:SCAL:FUNC SCAL |
Enables or disables displaying the unit string with measurements on the front panel when the scaling function is enabled.
Parameter | Typical Return |
---|---|
{ON|1|OFF|0}. Default: OFF. | 0 (OFF) or 1 (ON) |
Enable scaling with a gain of 100 and an offset of 5, and display "PSI" with measurements on the front panel. CALC:SCAL:FUNC SCAL |
