Warm-Up Time Required

Warm-up time is required before the synthesizer can meet

specifications. Operation to specifications requires 30 minutes to warm

up from a cold start at 0 to +55 degrees Celsius.

NOTE • For best results when calibrating an external leveling loop

configuration, both the External Detector Linearization and External

Modulator Gain Calibration must be run. When running these

calibrations, order matters; the External Modulator Gain Calibration

must be run only after an External Detector Linearization is run.

Running these calibrations a second time may yield a minor

improvement in accuracy; the accuracy improvement is less than

0.25 dB. Running these calibrations any additional times provides no

further accuracy improvement.

• For best results when performing an I/Q Calibration, both the

internal I/Q Calibration and I/Q External Source Adjustments should

be run. When running these calibrations, order matters; the I/Q

External Source Adjustments must be run only after an internal I/Q

Calibration is run. Running these calibrations any additional times

provides no further accuracy improvement.

• The most recently run level calibration supersedes any previous level

calibrations. This is because a calibration DAC is adjusted during a

level calibration and depending on which level calibration is

performed (IF Calibration or I/Q Upconverter Calibration), its DAC

settings are used.
