Specifications
Frequency
1. Operational, but unspecified, down to 100 kHz.
2. In ramp sweep mode (Option 007), resolution is limited with narrow spans and slow sweep speeds. Refer to ramp sweep
specifications for more information.
3. Time from GPIB trigger to frequency within 0.1 ppm of final frequency above 250 MHz or within 100 Hz below 250 MHz.
4. Add 12 ms (typ) when switching from greater than 3.2 GHz to less than 3.2 GHz.
5. N is a factor used to help define certain specifications within the document.
6. To optimize phase noise 5 dBm ± 2 dB.
7. 19 ms (typ) when stepping from greater than 3.2 GHz to less than 3.2 GHz.
8. Standard performance applies to units with serial numbers ending with 48050000 or greater. For units with lower serial
numbers, refer to the data sheet shipped with the unit or the version of this document dated November 6, 2007.
