Agilent/Keysight E8257DV01

The Agilent/Keysight E8257DV01 is a millimeter-wave frequency extension module that extends compatible Keysight signal generators into the sub-terahertz spectrum. Operating as part of Virginia Diodes’ Amplifier/Multiplier Chain (AMC) series, this module delivers output via WR1.0 waveguide and preserves the frequency accuracy and resolution of the host generator. It supports pulse, FM, and phase modulation directly from the base instrument, with frequency control and display managed through the host signal generator interface.

– Technical Specifications

• Frequency Range: 750 GHz to 1100 GHz
• Output Power: −23 dBm
• Waveguide Output: WR1.0 flange
• Power Supply: 9 V DC (included)
• Modulation Modes: Pulse, FM, ΦM

– Key Features

• Direct RF input from host signal generator—no intermediate stage required
• Frequency multiplier configuration on host generator must match SGX module label (N value) for accurate output frequency display
• Includes 9 V DC power supply and interconnect cables
• VDI User’s Guide and Keysight E8257DV01 Signal Generator Frequency Extension Module User’s Guide supplied on USB
• Input power limits defined in VDI documentation—exceeding maximum RF input power voids warranty

– Compatibility & Integration

The E8257DV01 operates with the following Keysight base signal generators:

• E8257D PSG
• E8267D PSG
• N5183B MXG
• N5173B EXG

Proper host generator configuration is mandatory. Set the frequency multiplier value to match the printed N parameter on the module label to ensure correct frequency indication. RF input must not exceed the maximum power level specified in the VDI User’s Guide. Only Keysight-approved accessories and power cords with equivalent or superior electrical ratings are permitted. Servicing requires qualified personnel; do not remove covers to prevent electrical shock hazard. Maintain proper earth grounding.
