U3020AS22

Description

The Keysight U3020AS22 is a 300 kHz to 26.5 GHz single connection multiple

measurement tests set with 4 ports in the forward path (a1-4), and 4 ports in

the reverse path (b1-4) that allow the user to connect a full 12-Port matrix.

There are two AUX output ports that allow the unit to connect to another

multiport test set or for some other application. This test set uses mechanical

RF switches. The test set mainframe is a rack mountable 4 EIA units high.

Switch control is only processed via the LAN or GPIB rear panel interfaces. All

front panel RF ports are female 3.5 mm.

This product has an autoranging line voltage input. Be sure the supply

voltage is within the specified range.

Power Requirements

— 100-240V AC (50/60 Hz)

— The instruments can operate with mains supply voltage fluctuations up to ±

10% of the nominal voltage.

— Air conditioning equipment (or other motor–operated equipment) should

not be placed on the same ac line that powers the Test Set.

— U3022AS22 maximum power is 50 W.

Environmental Tests

The U3020AS22 complies with all applicable safety and regulatory

requirements for the intended location of use.

— Operating Environment (Indoor Use)

— Operating Temperature 0 to 40 °C

—StorageTemperature:−40 to +70 °C

— Operating Altitude: 0 to 2000 meters (~ 6,562 feet)

— The instrument can safely operate in a relative humidity of 80% for

temperatures to 31 degrees C, decreasing linearly to 50% relative humidity

at 40 degrees C.
