units for TEMP, ACV, and DCV, and is summarized in Table 5-11.
:TEMPerature command
:TEMPerature <name>
:UNIT:TEMPerature <name> Specify TEMP units
Parameters <name> = C or CEL °C temperature units
F or FAR °F temperature units
K K temperature units
Query TEMPerature? Query temperature units
Description This command is used to specify the units for temperature measure-
ments.
:VOLTage commands
:AC <name>
:UNIT:VOLTage:AC <name> Specify ACV units
Parameters <name> = V AC voltage measurement units
DB dB AC voltage measurement units
DBM dBm AC voltage measurement units
Query :AC? Query AC voltage units
Description This command is used to select the units for ACV measurements. With
volt (V) units selected, normal AC voltage measurements are made for the
ACV function. With DB units selected, AC dB voltage measurements are
performed. The DBM units selection is used to make decibel measure
-
ments referenced to 1mW. dB and dBm measurements are explained fur-
ther in Section 2.
