The Keysight E1369A is a B-size, 1-slot VXI microwave switch driver module engineered for automated test systems requiring precise control of multiple coaxial switches. This register-based module accommodates up to three internal switches and controls two additional external switches, delivering a total switching capacity of five channels. It operates across microwave frequencies to 25.6 GHz and supports split-coil switch designs from Keysight/Agilent/HP 8762B/C, 8763B/C, and 8764B/C series, as well as equivalent third-party switches meeting specified electrical requirements.
## Technical Specifications
• **Module Type:** B-size, 1-slot, register-based VXI slave device (A16 addressing)
• **Switch Capacity:** Up to five coaxial switches total (three internal, two external)
• **Supported Switch Types:** 3-port, 4-port, or 5-port coaxial switches
• **Maximum Frequency:** 25.6 GHz
• **Control Interface:** 14-pin connector
• **Energizing Voltages:** Selectable internal (+5 VDC or +12 VDC) or external up to 42 Vpk
• **Switch Current:** Less than 1 A per switch
## Key Features
• Panel-labeled channels 00, 01, and 02 for easy identification; channels 03 and 04 available unlabeled
• Selectable internal voltage levels eliminate need for external supplies in many applications
• External voltage option accommodates up to 42 Vpk for specialized switch requirements
• Split-coil switch compatibility expands options beyond Keysight native switches
## Compatibility & Integration
The module integrates into VXI mainframes via P1 connector. Third-party switches are supported provided they feature split-coil designs, operate below 42 V, and draw less than 1 A per switch. Agilent 8761, 8766, 8767, 8768, and 8769 series switches are not compatible due to non-split coil architecture. C-size mainframe compatibility requires the E1403C interface module.
