6.7.5 Data Stream
Lets you choose data or a test pattern to output to the Wideband IF LVDS port. This
can help you set up your streaming target devices.
Remote Command
:OUTPut:DBUS2:DATA MEASure | TEST
:OUTPut:DBUS2:DATA?
Example
:OUTP:DBUS2:DATA TEST
Notes Selecting TEST routes a test pattern to the Wideband Digital Bus stream output
Preset MEAS (set by Restore Input/Output Defaults)
State Saved Saved in Input/Output State
6.7.6 I/Q Cal Out
The Baseband I/Q "Cal Out" port can be turned on with either a 1kHz or a 250kHz
square wave. This can be turned on independent of the input selection. Preset resets
this to OFF.
Remote Command
:OUTPut:IQ:OUTPut IQ1 | IQ250 | OFF
:OUTPut:IQ:OUTPut?
Example
:OUTP:IQ:OUTP IQ1
Dependencies Only available with Option BBA
Couplings An I/Q Cable Calibration or an I/Q Probe Calibration will change the state of the Cal Out port as
needed by the calibration routine. When the calibration is finished the I/Q Cal Out is restored to the
pre-calibration state
Preset
OFF
