322 Agilent N8211A/N8212A Performance Upconverter Synthetic Instrument Module, 250 kHz to 20 / 40 GHz
10 Digital Modulation Commands
This command is effective only if the state of the I/Q adjustment function is set to ON.
Refer to “:IQADjustment[:STATe]" on page 332.
Example
:DM:IQAD:QOFF -30
The example sets the Q channel offset to –30%.
*RST +0.00000000E+000
Range −5E1 to +5E1
:IQADjustment:QSKew
Supported N8212A
[:SOURce]:DM:IQADjustment:QSKew <val>
[:SOURce]:DM:IQADjustment:QSKew?
Adjusts the phase angle (quadrature skew) between the I and Q vectors by increasing or
decreasing the Q phase angle.
The <val> variable is expressed in degrees with a minimum resolution of 0.1.
If the N8211A/N8212A is operating at frequencies greater than 3.3 GHz, quadrature skew
settings greater than ±5 degrees will not be within specifications.
Positive skew increases the angle from 90 degrees while negative skew decreases the
angle from 90 degrees. When the quadrature skew is zero, the phase angle between the I
and Q vectors is 90 degrees.
This command is effective only if the state of the I/Q adjustment function is set to ON.
Refer to “:IQADjustment[:STATe]" on page 332.
Example
:DM:IQAD:QSKew 4.5
The example increases the phase angle by 4.5 degrees.
*RST +0.00000000E+000
Range −1E1 to +1E1
