:calculate:DB:reference? queries the dB reference value.
:calculate:DB:reference□ <value> sets the dB reference value.
When setting dB reference value, the value is an integer, and the range is between
+120dB and -120dB. MIN denotes -120dB, MAX denotes +120dB, and DEF denotes 0.
Return Format:
:calculate:DB:reference? returns the current dB reference value.
9. :calculate:DBM
Syntax:
:calculate:DBM?
Function:
The command queries dBm value.
Return Format:
The query returns the current dBm value.
10. :calculate:DBM:reference
Syntax:
:calculate:DBM:reference?
:calculate:DBM:reference□ <value>
Function:
The command queries and sets dBm reference resistance.
Parameters:
Name
Type
Range
Default
<value>
Consecutive integer
{ <range> |MIN|MAX|DEF}
600
Explanations:
:calculate:DBM:reference? queries the dBm reference resistance.
:calculate:DBM:reference□ <value> sets the dBm reference resistance.
When setting dBm reference resistance, the value should be an integer, and the range
is between 2 and 8000, unit is Ω. MIN denotes 2Ω, MAX denotes 8000Ω, and DEF
denotes 600Ω.
