E7760B with M1740A

mmWave 5G Non-Signaling Solution

Streamlined testing across any 3GPP mmWave band

Mobile operators around the world are accelerating 5G deployments to capture early

market opportunities. As a result, wireless equipment manufacturers need to support a

more rapid pace of development while addressing evolving 5G New Radio (NR)

specifications.

Most 5G mobile devices operating in mmWave frequency spectrum rely on modules

with highly integrated RFIC architectures. This requires new 5G designs to be verified

across both intermediate frequencies (IF) and mmWave frequencies. Since 5G

mmWave devices use phased-array antennas that lack connectorized ports,

performance validation needs to take place in Over-the-Air (OTA) test environments.

Creating and maintaining a calibrated system when using multiple platforms to perform

measurements in OTA test environments can be challenging and lead to unreliable

measurement results.

Keysight’s mmWave 5G non-signaling solution enables validation of a broad range of

5G modules in OTA test environments. Its single wideband transceiver (E7760B) and

remote radio head (M1740A) provide tunable access across four mmWave frequency

bands.

Performance Characteristics

Definitions

Specification (spec)

The warranted performance of a calibrated instrument that has been stored for a minimum of 2 hours

within the operating temperature range and after a 60-minute warm up period. Specifications are valid

from 20 to 35 °C unless otherwise noted.

Typical (typ)

The characteristic performance, that 95 percent of the units exhibit with a 95 percent confidence level.

This data, shown in Italics, is not warranted, does not include measurement uncertainty, and is valid only

at room temperature (approximately 23 ± 5 °C).

Nominal (nom)

The mean or average characteristic performance, or the value of an attribute that is determined by

design. This data is not warranted and is measured at room temperature (approximately 23 ± 5 °C).

Conditions

The specifications in this document apply to a single E7760B wideband transceiver connected to a single

M1740A remote radio head (RRH).
