The 6160B Frequency Synthesizer is the industry's most popular VHF synthesizer because of its high spectral purity. It produces frequencies from 1 MHz to 160 MHz in two ranges: 1 MHz to 12 MHz and 10 MHz to 160 MHz.Frequency resolution is 0.1 Hz on the 12 MHz range and 1.0 Hz on the 160 MHz range. A unique feature of the 6160B is that the highest internally-generated frequency is that of the output VCO. This makes servicing easier, and eliminates UHF EMC problems. SInce the output VCO operates from 80 to 160 MHz, frequency division is employed for coverage of lower frequencies. This results in improved spurious specifications for frequencies lower than 80 MHz. Phase noise is similiarly reduced for lower bands. Adjustable output up to +13 dBm into 50-ohms. Local or remote control. Level maintained, absolute phase noise <-62 dBc.
(one of the above is that model)
Low Frequency Range: 1-4 MHz with 0.1 Hz Resolution
High Frequency Range: 4-40 MHz with 1.0 Hz Resolution.
Main RF Output (rear): Fixed Level _21 dBm into 50 ohms.
Auxillary Output: 1 MHz and 100 kHz.

The Very Large Array, one of the world's premier astronomical radio observatories, consists of 27 radio antennas in a Y-shaped configuration on the Plains of San Agustin fifty miles west of Socorro, New Mexico. Each antenna is 25 meters (82 feet) in diameter. The data from the antennas is combined electronically to give the resolution of an antenna 36km (22 miles) across, with the sensitivity of a dish 130 meters (422 feet) in diameter
