:VOLTage:DC?
Description:
This command is used to select the units for DCV measurements. With volt (V) units selected, normal
DC voltage measurements are made for the DCV function. With DB units selected, DC dB voltage
measurements are performed. The DBM units selection is used to make decibel measurements
referenced to 1mW.
:DB:REFerence <n>
Command Syntax:
:UNIT:VOLTage:DC:DB:REFerence <n>
Command parameter:
<n> = 1e-7 to 1000
Query:
:DB:REFerence?
Description:
This command is used to specify the dB reference level. The DB unit is selected, DCV dB
measurements are made using the specified dB reference level.
The reference level is specified in volts and is not range dependent. For example: a dB reference level
of 1 is 1V on all DCV measurement ranges.
:DBM:IMPedance <n>
Command Syntax:
:UNIT:VOLTage:DC:DBM:IMPedance <n>
Command Parameter:
<n> = 1~9999
Query:
:DBM:IMPedance?
Description:
This command is used to specify the dBm reference impedance level. When dBm units is selected,
DCV dBm measurements are made using the specified dBm reference impedance.
The reference impedance is specified in ohms and is not range dependent. For Example: a dBm
reference level of 500 is 500 on all DCV measurement ranges. A rational number is rounded to the
nearest valid integer value.
