Information

The System Noise Monitors described in this Instruction Manual /7310 and(7320) are functionally identical. Each provides a readout of the Noise Figure of a unit under test (UUT) when connected in a valid measurement setup. The minimum test setup consists of a SNM, the UUT, and a solid state noise source of the Ailtech 7600 series. The 7310 and 7320 have optional meter scales which provide an Operating Noise Temperature readout in lieu of Noise Figure. The 7310 and 7320 SNM’s are referred to as analog units because the readout is by a meter with two ranges. Range selection is made by means of a front panel switch. Ailtech also manufactures the 7360 and 7370 which indicate Noise Figure by means of a three-digit LED display and are generally referred to as digital units. The 7310 is 7½ inches wide and is intended for bench-top use while the 7320 is approximately 17 inches wide and is intended for rack mounting. The optional Rack Mount Angle Brackets (Option 11) must be attached for mounting in a standard 19 inch rack.
