4 Input/Output Functions
Input/Output
Q Input Z
Selects the input impedance for the Q channel. The impedance applies to both the Q and Q-bar ports.
The input impedance controls the hardware signal path impedance match. It is not used for converting
voltage to power. The voltage to power conversion always uses the Reference Z parameter. The
Reference Z parameter applies to both I and Q channels.
Key Path
Input/Output, I/Q, Q Setup
Remote Command
:INPut[1]:IQ:Q:IMPedance LOW|HIGH
:INPut[1]:IQ:Q:IMPedance?
Example Set the Q channel input impedance to 1 MΩ
INP:IQ:Q:IMP HIGH
Notes LOW = 50 Ω, HIGH = 1 MΩ
When IQ Path is I+jQ, the I Input Z setting must be the same as the Q Input Z setting. If the settings
of the two inputs do not match, an error condition message is generated, 159;Settings Alert;I/Q
mismatch:Input Z.
Couplings Input impedance is a built-in characteristic of a probe. Therefore, whenever a probe is sensed, this
key is disabled and the value is set to match the probe.
When no probe is sensed and Q Same as I is On, the value set for I will also be copied to Q. This key
is disabled when Q Same as I is On.
Preset LOW
State Saved Yes
This is unaffected by Preset but is set to the default value on a "Restore Input/Output Defaults" or
"Restore System Defaults->All"
Range 50 Ω | 1 MΩ
Initial S/W Revision Prior to A.02.00
Q Skew
Sets the skew factor for the Q channel. The skew will shift the channel's data in time. Use this to
compensate for differences in the electrical lengths of the input paths due to cabling and probes.
Key Path
Input/Output, I/Q, Q Setup
Remote Command
[:SENSe]:CORRection:IQ:Q:SKEW <seconds>
[:SENSe]:CORRection:IQ:Q:SKEW?
Example Delay the data for the Q channel by 10 ns.
CORR:IQ:Q:SKEW 10 ns
Preset 0
State Saved Yes
This is unaffected by a Preset but is set to the default value on a "Restore Input/Output Defaults" or
"Restore System Defaults->All"
Range 0 s to 100 ns
168 EMI Receiver Mode Reference
