U3020AS62 Description

Description

The Keysight U3020AS62 Test Set is a DC to 26.5 GHz Signal Distribution instrument. The Test

Set functionally is a Dual SP6T 6-Port Latching, Terminated switch in which both switches are

functionally ganged together. The Test Set mainframe is a rack mountable two EIA units high.

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

Figure 1 U3020AS62

Verifying the Shipment

To verify the contents shipped with your product, refer to the “Box Content List” included with

the shipment.

Inspect the shipping container. If the container or packing material is damaged, it should be

kept until the contents of the shipment have been checked mechanically and electrically. If

there is physical damage refer to “Contacting Keysight” on page 35. Keep the damaged

shipping materials (if any) for inspection by the carrier and an Keysight Technologies

representative.

U3020AS62 General Performance

General Performance

The Test Set performance is specified for a standalone instrument.

Power Requirements

•100/120/220/240 VAC (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.

•U3022AS62 maximum power is 50 W.

Environmental Tests

The U3020AS62 complies with all applicable safety and regulatory requirements for the

intended location of use.

•Operating Environment (Indoor Use)

•Operating Temperature 0 to 55 °C

•Storage Temperature: −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.

This product has an auto-ranging line voltage input. Be sure the supply

voltage is within the specified range.

Keysight U3020AS62 User's and Service Guide

Definitions

•Specifications describe the performance of parameters covered by the product warranty

(temperature 0 to 50 °C, unless otherwise noted.)

•Typical describes additional product performance information that is not covered by the

product warranty. It is performance beyond specification that 80% of the units exhibit with a

95% confidence level over the temperature range 20 to 30 °C. Typical performance does not

include measurement uncertainty.

•Nominal values indicate expected performance or describe product performance that is useful

in the application of the product, but is not covered by the product warranty.

•Characteristic Performance describes performance parameter that the product is expected to

meet before it leaves the factory, but is not verified in the field and is not covered by the

product warranty. A characteristic includes the same guard bands as a specification.

Figure 2Front Panel

LAN Reset

The LAN reset button restores the instrument's default LAN configuration.

Port Select LEDs

The LEDs indicate the RF Port path that is presently operational, all other port inputs are

terminated by an internal 50 Ohm load.

Input/Output Ports

There are two separate signal channels, A and B. Each channel has one output port and six input

ports. All connectors are 3.5 mm female.

Instrument State LEDs

When the power is applied to the U3020AS62, the instrument enters its power-on sequence

which requires several seconds to complete. The LEDs provide information on the state of the

instrument during power-on and during upgrades of the instrument firmware. Table 6 on page 11

identifies the instrument states based on the color and functioning of the LEDs.

Standby Switch

Note that this switch is Standby only, not a line switch. The main power cord can be used as the

system disconnecting device. It disconnects the mains circuits from the mains supply.
