Internal Bias Tee Voltage
:INPut<port_no>:BIAS:VOLTage
Description: Sets the voltage of the internal bias tee for the specified port number.
<port_no> is the specified internal bias tee port number, 1 or 2. The
query version of this command returns either the measured internal
bias tee voltage or the set internal bias tee voltage (both are returned in
Volts). Note that the measured voltage can be slightly different than the
set voltage depending on the load conditions. To return the last
measured internal bias tee voltage for the specified port number, send
the query command either with no value specified after the “?” (default
condition) or with a value of 0 specified after the “?”. Note that the query
result for the measured internal bias tee voltage is valid only if the Bias
Tee state is set to internal. If a value of 1 is specified after the “?”, then
the query version of this command returns the internal bias tee voltage
that was set for the given port number.
Syntax: :INPut<port_no>:BIAS:VOLTage <voltage>
:INPut<port_no>:BIAS:VOLTage? [0|1]
Cmd Parameter: <NRf> <12 to 32 Volts>
Query Response: <NR3> <Volts>
Range: 12 V to 32 V
Default Value: +12 V when querying the internal bias tee voltage that was set
(:INPut<port_no>:BIAS:VOLTage? 1). The default value for
querying the last measured bias tee voltage may be slightly different
depending upon what is connected to the port.
Default Unit: Volts
