Baseband I/Q - Select Input Impedance
:INPut:IMPedance:IQ U50|B600|U1M|B1M
:INPut:IMPedance:IQ?
Selects the characteristic input impedance when input port is set to I or
Q. This is the impedance value as well as the unbalanced (U) or
balanced (B) impedence mode.
1000000 or 1E6 sets input impedance to 1 M ohm.
Factory Preset
and *RST: U1M
Remarks: You must be in the Basic, W-CDMA, cdma2000 mode to
use this command. Use INSTrument:SELect to set the
mode.
History: Added revision A.05.00
Baseband I/Q - Select Input Impedance Reference
:INPut:IMPedance:REFerence <integer>
:INPut:IMPedance:REFerence ?
Sets the value of the input impedance reference when input port is set
to I or Q.
1000000 or 1E6 sets input impedance to 1 M ohm.
Range: 1 to 10,000,000.
Default Units: ohm
Remarks: You must be in the Basic, W-CDMA, cdma2000 mode to
use this command. Use INSTrument:SELect to set the
mode.
