:INPut Subsystem

This subsystem controls characteristics of the input port.
:INPut<port_no>:BIAS:CURRent <current>
:INPut<port_no>:BIAS:CURRent? [0|1]
Description: Sets the internal bias tee current limit for the specified port. When this
Syntax: :INPut<port_no>:BIAS:CURRent <current>
Cmd Parameter: <NRf> <current> (milliampere)
Query Response : <char> [0|1] (returns value in milliampere)
Default Value: 450 mA when querying the internal current limit
Default Unit: milliampere (mA)
Range: 0 mA to 450 mA
Front Panel Access: Shift-3 (Sweep), Configure Ports, Bias Tee Setup, Int Current Limit P2
:INPut:BIAS:INTernal:TRIPped[:STATe]?
Description: Returns whether the internal bias tee is tripped. Returns 1 for tripped,
Cmd Parameter: NA (query only)
Query Response : <boolean> [0|1]
Front Panel Access: NA

limit is exceeded, the Bias Tee trips (turns OFF). <port_no> is the
specified internal bias tee port number 2. The query version of this
command returns either the measured internal current or the set
internal current limit (both are returned in milliampere units). To
return the measured internal current 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 current 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 current
limit that is set for the given port number.
:INPut<port_no>:BIAS:CURRent? [0|1]
(:INPut<port_no>:BIAS:CURRent? 1). The default value for
querying the measured current depends upon what is connected to the
port.
otherwise returns 0.
