The Keysight (Agilent) N5450A InfiniiMax Extreme Temperature Extension Cable extends compatible InfiniiMax probes into environmental chambers and thermal test environments. This 36-inch matched cable pair maintains signal integrity across extreme temperature ranges, delivering flat frequency response at temperature extremes and enabling reliable high-fidelity measurements in automotive electronics, mobile device testing, and hard disk drive endurance evaluations.
Technical Specifications
-# Bandwidth & Temperature Performance
Bandwidth varies by probe head configuration. With the N5381A probe head, typical bandwidth exceeds 12 GHz across an operational temperature range of −55 to +150 degrees Celsius. With the E2677A probe head, typical bandwidth exceeds 7.5 GHz across −25 to +80 degrees Celsius.
-# Physical Configuration
• Cable length: 36 inches (92 cm)
• Supplied as matched pair
-# Thermal Cycling Capability
The cable supports extended thermal cycling in environmental chamber applications. Test cycle counts depend on temperature range and probe head type:
• N5381A configuration: Over 250 cycles at full −55 to +150 degrees Celsius range
• E2677A configuration: Over 1000 cycles at −25 to +80 degrees Celsius range
– Key Features
• Flat frequency response maintained at both temperature extremes
• Enables probe operation outside environmental chambers via external probe amplifier
• Preserves signal fidelity under sustained thermal stress
– Typical Applications
• In-chamber probing during thermal testing of automotive electronics
• Mobile device thermal validation
• Hard disk drive endurance characterization
• Multi-cycle thermal chamber testing
– Compatibility & Integration
The N5450A interfaces with Keysight InfiniiMax probe heads including the 1130A-34A, 1168A/69A, and N2800A-03A. Operation with external probe amplifiers outside the thermal chamber is supported.
Product Status: Discontinued as of June 1, 2012. End of support: September 1, 2017. The N5450B is the recommended replacement.
