Input/Output
Q Same as I
Many, but not all, usages require the I and Q channels have an identical setup. To simplify channel setup,
the Q Same as I will cause the Q channel parameters to be mirrored from the I channel. That way your
only need to set up one channel (the I channel). The I channel values are copied to the Q channel, so at
the time Q Same as I is turned off the I and Q channel setups will be identical. This does not apply to
Probe settings or to parameters that determined by the probe.

Q Differential Input
Selects differential input on or off for the Q channel. For differential input (also called balanced input),
the analyzer uses both the Q and Q-bar ports. When differential input is off (also called single-ended or
unbalanced input), the analyzer uses only the Q port.

:INPut:IQ:MIRRored OFF|ON|0|1
:INPut:IQ:MIRRored?
Turn off the mirroring of parameters from I to Q.
INP:IQ:MIRR OFF
Only displayed for the Q channel. When Yes, the I channel values for some
parameters are mirrored (copied) to the Q channel. However, when a
parameter is determined by the type of probe and a probe is sensed, the probe
setting is always used and the I channel setting is ignored. The following
parameters are mirrored:
Differential Input (when not determined by probe)
Input Z (when not determined by probe)
This is unaffected by a Preset but is set to the default value (Q Same as I set to
"On") on a "Restore Input/Output Defaults" or "Restore System
Defaults->All"
Saved in instrument state.

"Q Same as I" when On, otherwise none.
