2.4.3 CALCulate:SCALe:FUNCtion {DB|DBM}
CALCulate:SCALe:FUNCtion?
Selects the operation that will be performed by the scaling function:
DB performs a relative dB computation. The result will be the difference between the
input signal and the stored DB relative value (CALCulate:SCALe:DB:REFerence),
with both values converted to dBm (dB = measurement indBm
– relative value in
dBm).
DBM performs a dBM computation. The result is logarithmic and is based on a
calculation of power delivered to a reference resistance
(CALCulate:SCALe:DBM:REFerence), relative to 1 milliwatt. (dBm = 10 × log10
(measurement 2 / reference resistance / 1 mW)).
Note:
This command applies only to ACV and DCV measurement functions.
Parameter
Typical Return
{DB|DBM}
DBorDBM
Enable the DB scaling function referenced to the next
measurement taken:
CALC:SCAL:FUNC DBM
CALC:SCAL:STAT ON
For the dB function, the reference value can be automatically selected using the first
measurement converted to dBm as the reference value
(see CALCulate:SCALe:REFerence:AUTO), or it can be specified by
CALCulate:SCALe:DB:REFerence.
Scaling function results must be in the range of -1.0E+24 to -1.0E-24, or +1.0E-24 to
1.0E+24. Results outside these limits will be replaced with -9.9E37 (negative infinity),
0, or 9.9E37 (positive infinity).
This parameter is set to its default value after a Factory Reset.
