Service Key Descriptions
IF Flatness
Immediately executes an alignment of the Current IF Flatness, for the
purpose of improving the absolute amplitude accuracy within FFT
Sweeps and improving the group delay in some digital demodulation
measurements. The instrument will stop any measurement currently
underway, perform the alignment, then restart the measurement
from the beginning.
The Advisory Event “Alignment complete” is displayed when the
alignment is complete.
Align Current IF Flatness can be interrupted by pressing the
Cancel
(ESC)
front-panel key. When this occurs, no new Current IF Flatness
alignment data will be employed.
Current System
Gain
Immediately executes an alignment of the Current System Gain, for
the purpose of improving small amplitude variations that occur as
resolution bandwidth is switched. This alignment is done by
measuring the response of the current system state configuration to
the 50 MHz amplitude reference signal. All subsequent
measurements are then compensated appropriately for absolute
amplitude accuracy. The instrument will stop any measurement
currently underway, perform the alignment, then restart the
measurement from the beginning.
The Advisory Event “Alignment complete” is displayed when the
alignment is complete.
Align Current System Gain can be interrupted by pressing the Cancel
(ESC) front-panel key. When this occurs, no new Current System
Gain alignment data will be employed.
LO Phase Noise
Immediately executes an optimization for LO Phase Noise. When the
optimization is finished the value is stored in non-volatile memory.
The instrument will stop any measurement currently underway,
perform the alignment, and then restart the measurement from the
beginning (similar to pressing the
Restart
key).
