Keithley 7078-TRX-3 Three-Slot Triaxial Cable (3 Feet)

The Keithley 7078-TRX-3 is a 3-foot (0.9 m) low-noise triaxial cable assembly featuring 3-slot male triaxial connectors on both ends. Engineered for sensitive measurements in laboratory and industrial environments, this cable minimizes noise and interference to preserve signal integrity across precision measurement applications. High-quality construction maintains performance in demanding test setups where signal fidelity is critical.

## Technical Specifications

• **Cable Length:** 3 feet (0.9 m)
• **Connector Type:** 3-slot male triaxial connectors (both ends)
• **Maximum Working Voltage:**
– 600 V peak (center conductor to inner shield)
– 1300 V peak (center conductor and inner shield to outer shell)
• **Maximum Working Current:** 1 mA
• **Contact Resistance:** < 0.5 Ω
• **Insulation Resistance:** 10¹⁵ Ω (center conductor to inner shield, 500 V test voltage, 23°C at <40% RH)

## Key Features

• Triple-conductor design with independent shielding layers reduces crosstalk and EMI coupling
• Operating temperature range: 0°C to 50°C (32°F to 122°F)
• Operating humidity: Up to 70% RH at ≤35°C
• Weight: Approximately 0.454 kg
• Connector maintenance: Keep free of contaminants; clean with methanol if required to maintain maximum insulation resistance

## Typical Applications

Low-current and low-voltage precision measurements where noise rejection and signal fidelity are essential. Ideal for picoammeter, electrometer, and source measure unit (SMU) installations requiring triaxial connectivity.

## Compatibility & Integration

Direct compatibility with Keithley SMUs (237, 2634B, 2635A, 2635B, 2636A, 2636B Series), picoammeters (6220, 6221, 6487 Series), electrometers (6514, 6517A, 6517B Series), and matrix cards (7072, 7174A Series). Adapter variants enable integration with additional test equipment.
