172 Agilent N8211A/N8212A Performance Upconverter Synthetic Instrument Module, 250 kHz to 20 / 40 GHz
7 System Commands
:IQ:STOP
Supported All
:CALibration:IQ:STOP <val><units>
:CALibration:IQ:STOP?
Sets the stop frequency and automatically sets the calibration type to User for an I/Q
calibration. The setting enabled by this command is not affected by a power-on, preset, or
*RST command.
Example
:CAL:IQ:STOP 2GHZ
The example sets the stop frequency for an IQ calibration to 2 GHz.
:WBIQ
Supported N8212A
:CALibration:WBIQ
Initiates a wideband I/Q calibration for a range of frequencies. For setting range
frequencies, refer to “:WBIQ:STARt" on page 173, and“:WBIQ:STOP" on page 174
command descriptions.
:WBIQ:DC
Supported N8212A
:CALibration:WBIQ:DC
Performs a one to two second adjustment that is not traceable to a standard. However, it
will minimize errors associated with offset voltages. This adjustment minimizes errors for
the current N8212A setting and at a single frequency. The DC adjustment is volatile and
must be repeated with each setting change. This command can be sent while the RF On/Off
is set to Off and the adjustment will be valid when RF is enabled.
The wideband I/Q DC adjustment is dependent upon a number of instrument settings. If
any of the N8212A settings change, the adjustment will become invalid. The dependent
instrument settings are:
• RF frequency
• I/Q attenuation level
• I/Q polarity settings
• Path settings (Internal I/Q Mux Path 1 or Path 2)
