:INP:IQ:IMP 50
Notes Provided for E4406A code compatibility.
The enum values translate as follows:
U50: Differential Input = Off, Input Z = 50Ω
B50: Differential Input = On, Input Z = 50Ω
U1M: Differential Input = Off, Input Z = 1 MΩ
B1M: Differential Input = On, Input Z = 1 MΩ
This command is for backwards compatibility. It combines the Input Z (50Ω or 1 MΩ) parameter
with the Differential Input (Off = "Unbalanced", On = "Balanced") parameter into a single
enumeration.
This backwards compatibility SCPI command was for an instrument without independent
settings for the I and Q channels. Therefore, it is tied only to the I channel and does not provide
an equivalent for the Q channel. For proper operation of the backwards compatibility command Q
Same as I should be set to On.
Also, note the subtle difference between this SCPI command and the backwards compatibility
command for Input Z. The Input Z SCPI has "IQ" before "IMP" while this command has that
order reversed.
Couplings This command does not have an independent parameter, but instead is tied to the Differential
Input and Input Z parameters. The coupling for those parameters apply to this command too.

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 you 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
