5-6 :INPut Subsystem
:INPut:BIAS:STATe OFF|INTernal
:INPut:BIAS:STATe?
Description: Enables or disables the bias tee. Query returns OFF|INT. For OFF
Parameter: OFF|INTernal
Cmd Parameter: <char> OFF|INTernal
Query Response: <char> OFF|INT
Default Value: OFF
Front Panel Access: Shift-3 (Sweep), Configure Ports, Bias Tee Setup, Bias Tee
:INPut<port_no>:BIAS:VOLTage <voltage>
:INPut<port_no>:BIAS:VOLTage? [0|1]
Description: Sets the voltage of the internal bias tee for the specified port number.
Cmd Parameter: <NRf> <12 to 32 Volts>
Query Response: <NR3> <Volts>
Default Value: +12 V when querying the internal bias tee voltage that was set
Default Units: Volts
Range: 12 V to 32 V

state, query returns OFF (not 0).
<port_no> is the specified internal bias tee port number (currently,
only port 2 is supported). 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.
(: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.
