The 9600FLT 1 GHz Wide Offset Phase Noise Filter accessory is for high-performance spectrum analyzer wide-offset phase noise tests. The filter connects easily to 96xx Reference Source models in bench top or rack-mounted installations. It supports the established practice of using filters to reduce noise levels at wide (high) offsets for improving test margins.
Use the Filter only at 1 GHz. It rejects phase noise at offsets greater than 1 MHz from the 1 GHz carrier (both sidebands are rejected). Use the filter only when the phase noise specification of the 96xx RF Reference Source is not considered sufficient for the target workload. Only the highest performance spectrum analyzers are likely to require the filter. The filter connects in series with the umbilical lead of the 9640A-50 or 9640A-75 Leveling Head. Use the supplied mounting kit to conveniently attach the filter to the front left handle of the Reference Source. This mount is fully compatible with the Y9600 Rack Mount accessory.
