:DB:REFerence
Command Syntax:
:UNIT:VOLTage:AC:DB:REFerence
Command Parameter:
= 1e-7 to 1000 Specify reference voltage
Query:
:DB:REFerence? Query reference voltage
Description:
This command is used to specify the dB reference level. When DB unit is selected, ACV dB
measurements are made using the specified reference voltage.
The reference level is specified in volts and is not range dependent. For example: a dB reference
level of 1 is 1 V on all ACV measurement ranges.
:DBM:IMPedance
Command Syntax:
:UNIT:VOLTage:AC:DBM:IMPedance
Command parameter:
= 1 to 9999 Specify reference impedance
Query:
:DBM:IMPedance? Query reference impedance.
Description:
This command is used to specify the dBm reference impedance level. When dBm unit is selected,
ACV dBm measurements are made using the specified 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 ACV measurement ranges.
:VOLTage:DC
Command Syntax:
:UNIT:VOLTage:DC
Command Parameter:
= V DC voltage measurement units
DB dB DC voltage measurement units
DBM dBm DC voltage measurement units
Query:
:VOLTage:DC? Query DC voltage units
