4 Input/Output Functions
Input/Output
the probe attached to the main port and the data for the probe attached to the complementary port are
cleared. When Differential Input is off, only data for the probe attached to the main port is cleared.
Key Path
Input/Output, I/Q, I Setup | Q Setup, I Probe | Q Probe
Remote Command
:CALibration:IQ:PROBe:I|Q:CLEar
Example Clear the calibration data for the I channel and the current probe (with EEPROM identification) or
probe type (without EEPROM identification).

Initial S/W Revision Prior to A.02.00
RF Calibrator
Lets you choose a calibrator signal to look at or turns the calibrator "off".
Key Path
Input/Output
Remote Command
[:SENSe]:FEED:AREFerence REF50|REF4800|OFF
[:SENSe]:FEED:AREFerence?
Example FEED:AREF REF50 selects the 50MHz amplitude reference as the signal input.
FEED:AREF REF4800 selects the 4.8GHz amplitude reference as the signal input
FEED:AREF OFF turns the calibrator "off" (switches back to the selected input – RF or I/Q)
Dependencies Selecting an input (RF or I/Q) turns the Calibrator OFF. This is true whether the input is selected by
the keys or with the [:SENSe]:FEED command.
The 4.8GHz internal reference is only available in some models and frequency range options. If the
4.8 GHz reference is not present, the 4.8 GHz softkey will be blanked, and if the REF4800 parameter
is sent, the analyzer will generate an error.
Couplings When one of the calibrator signals is selected, the analyzer routes that signal (an internal amplitude
reference) to the analyzer, and changes the main input selection to RF so the calibrator signal can be
seen. When you turn the calibrator off it does not switch back to the previously selected input.
Preset OFF
State Saved Saved in instrument state
Readback Off, 50MHz, 4.8GHz
Initial S/W Revision Prior to A.02.00
Remote Command
:CALibration:SOURce:STATe OFF|ON|0|1
:CALibration:SOURce:STATe?
Notes For ESA backwards compatibility.
In the ESA the calibrator was a separate output which you connected to the input and switched on
with this command.
In the X-Series, the ON parameter is aliased to the [SENSe]:FEED:AREF REF50 command and the
OFF parameter is aliased to [SENSe]:FEED:AREF OFF.
