Specifications
Specifications refer to the performance standards or limits
against which the U9391C/F are tested.
Typical characteristics are included for additional
information only and they are not specifications. These are
denoted as “typical”, “nominal” or “approximate” and are
printed in italic.

* When driven by low phase noise sources, this comb generator will operate at frequencies lower than 10MHz, but perfor-
mance is not guaranteed.
† For operations below 100MHz, use a square wave to drive the comb generator.
‡ The specifications refers to the raw performance data. For NVNA application, the phase performance are corrected with the
calibration data.
Not at spurious frequency. Spurious frequency at n*250MHz and also at input drive frequency.
