CAST’s Hardware Stack core is expected to increase network throughput of
the RF and microwave analyzer
Woodcliff Lake, NJ — July 7, 2026 — CAST, a leading provider of high performance
semiconductor IP cores, today announced that Keysight Technologies has licensed
CAST’s 1G/10G TCP/IP Hardware Stack IP core for integration into its FieldFox
handheld radio frequency (RF) and microwave analyzers.
Keysight’s FieldFox family is designed for rugged, portable RF field testing and includes
configurations for spectrum analysis, network analysis, cable and antenna test, and
related measurement functions. Keysight selected the CAST core to add proven TCP/IP
networking capability.

“We evaluated a range of options for this functionality,” said Anna Svendsen,
NPI Solutions Planning Manager at Keysight. “The CAST core’s signal
interfaces aligned well with our requirements, and its configurability and
standards compliance were essential. CAST’s licensing model, documentation,
testbenches, and support team made the integration straightforward. This
integration supports Keysight’s continued investment in advancing
high-performance, field-ready test solutions for next-generation RF and
microwave applications.”

About the TCP/IP Hardware Stack IP Core
CAST’s TCPIP-1G/10G IP core delivers consistent, high-throughput data exchange with
low-latency Ethernet operation, ideal for demanding real-time connectivity
requirements. Its fully autonomous architecture eliminates the need for CPU
intervention, removing processor overhead while reducing overall system power
consumption, a critical advantage for battery-powered field instruments like the FiedFox
line.
Designed for seamless integration, the core supports industry-standard AMBA®
interfaces and offers exceptional scalability, including support for up to 32,000
simultaneous TCP sessions. Optional UDP, IGMP, and DHCP functionality provide
additional flexibility for a wide range of networking environments.
With years of hardware stack experience behind it, CAST’s TCP/IP Hardware Stack IP
core has been deployed by customers worldwide across diverse markets, including
automotive, consumer, aerospace, data center, industrial, and medical. Customers can
choose the standalone core, or pre-integrated solutions incorporating the TCP/IP
hardware stack in subsystems targeted for applications such as video over IP.
