Service Key Descriptions
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.
RF
This is exactly the same as the customer accessible Align Now, RF
with one exception: the alignment can be invoked even if a previous
Align Now, All has not been executed (this key is not grayed-out if
using default alignment data). See description of Align Now, RF in the
User's Guide.
Current Gain System
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 Adjustment (software versions ≥ A.04.00)
Immediately executes an optimization LO for 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).
Diagnostics (software versions ≥ A.04.00)
Pressing Diagnostics in the Service Menu brings up the Service
Diagnostics submenu. The functions in this menu allow the
technician to do more detailed, lower-level troubleshooting.
Show Software
The Show Software screen displays revision information for Keysight
internal software that comprises the embedded application and
programmable hardware devices (FPGAs and PLDs).
