Using Baseband I/Q Inputs (Option B7C)

Table 4-9	I and Q Offset Increment vs. I/Q Range
		I and Q
	I/Q Range	Offset
		Increment
	1 Volt	2 mV
	500 mV	1 mV
	250 mV	.5 mV
	125 mV	.25 mV

•Q Offset - Use Q Offset to input a value in Volts to offset the

measured Q value. The default value is 0.0000 Volts, the min/max values are ± 2.5600 Volts. The tuning increment depends on the I/Q Range setting as shown in Table 4-9. This value only affects the displayed results, and does not appear as a correcting voltage at the probe.

•I/Q Input Z - This key lets you access a menu to select an input impedance for baseband I/Q input signals. The selection of input

impedance is coupled to a connector “balance” configuration. If I/Q Input Z is set to 1 M Ω, the setting for I/Q Z Ref for Input Z = 1MΩ key becomes effective. For details, refer to “Selecting Baseband I/Q Input Impedance” on page 164.

•I/Q Z Ref for Input Z = 1M Ω - This key is used to select the

1 M Ω input reference Z value in Ohms. This key is effective only when I/Q Input Z is set to a 1 M Ω setting. The default value is 50.0 Ω. The value range is 0 Ω to 10 M Ω, with a tuning increment of 1.0 Ω. For more details, refer to“Selecting Baseband I/Q Input Impedance” on page 164.
