E8257D Option HAR Specifications
Specifications
The E8257D Option HAR provides improved absolute phase noise in the 0.98 to 500 MHz
frequency range. To achieve these improvements the Divider Mode must be turned On.
See
“Operation” on page 8 .
The E8257D Option HAR impacts standard instrument performance for frequencies
≤
3.2 GHz. Standard operation for frequencies above 3.2 GHz has not been affected. If
Divider Mode is left on for frequencies outside of 0.98 to 500 MHz the “ALC Bandwidth”
will be limited to 100 Hz.
