Keysight Used N469xD Series Electronic Calibration (ECal) Modules

Shop Used N469xD ECal Modules

Compare available N4690D, N4691D, N4692D, N4693D and N4694D modules by frequency range, connector type and price.

Keysight N469xD electronic calibration (ECal) modules are precision 2-port VNA calibration solutions for microwave measurements. Compared with traditional mechanical VNA calibration kits, ECal modules simplify calibration with a single connection to the module. The series covers frequencies up to 67 GHz with Type-N, 3.5 mm, 2.92 mm, 2.4 mm, 1.85 mm and 7 mm connector interfaces.

Choose the N4690D for Type-N measurements up to 18 GHz, N4691D for 3.5 mm up to 26.5 GHz, N4692D for 2.92 mm up to 40 GHz, N4693D for 2.4 mm up to 50 GHz, or N4694D for 1.85 mm up to 67 GHz. The N4696D provides a 7 mm interface up to 18 GHz. All N469xD models support Option 0DC, which extends the lower calibration frequency limit to DC.

Used inventory varies by model, configuration and condition. Keysight Premium Used modules are fully refurbished and calibrated by Keysight, with the same warranty as new. For all other offers, calibration status and warranty are shown on each listing, and fresh Keysight calibration can be added.

Keysight Calibration

Why OEM Calibration Matters When Buying Used ECal

An ECal module is only as accurate as the characterization data stored inside it. When buying used, verified calibration matters as much as physical condition. All Keysight Premium Used modules include OEM calibration, while fresh Keysight calibration can be added to other used offers.

Calibrated Where It Was Built

N469xD modules are calibrated by Keysight, using specially manufactured equipment and standards traceable to national standards.

Verified Against Specifications

Each module is tested against its warranted specifications using precision calibration standards and traceable measurement procedures.

Documented Results

Keysight calibration includes a calibration certificate and a report with measured values, specifications and uncertainties.

Frequently Asked Questions

Choose based on frequency range and connector type. The N4690D supports Type-N 50 ohm up to 18 GHz, the N4691D 3.5 mm up to 26.5 GHz, the N4692D 2.92 mm up to 40 GHz, the N4693D 2.4 mm up to 50 GHz, and the N4694D 1.85 mm up to 67 GHz. The N4696D supports 7 mm connectors up to 18 GHz.

These options define the lower frequency limit of N469xD ECal modules. Option 0DC extends calibration down to DC and is available for all models. Without Option 0DC, the N4690D, N4691D and N4696D start at 300 kHz (Option 003), while the N4692D, N4693D and N4694D start at 10 MHz (Option 100). Option 0DC is particularly useful for broadband device modeling and time-domain measurements.

No. N469xD modules support various Keysight PNA, ENA, PXIe, Streamline and FieldFox analyzers, but compatibility depends on the ECal model, analyzer and firmware. For example, the N4693D and N4694D are not supported on the E5061B, E5063A, E5071C or E5072A. Check the Electronic Calibration Modules Reference Guide for detailed compatibility requirements.

N469xB modules belong to an earlier generation of Keysight electronic calibration modules, while N469xD modules are part of the newer series. Frequency coverage, connector configurations, calibration options and analyzer compatibility vary by model. Check the specifications of each module before selecting a replacement.

While all equipment sold through our official Keysight Used Equipment Store is certified by us as the original manufacturer, eligible products can also benefit from fresh Keysight calibration and KeysightCare support. Keysight Premium Used goes a step further, offering equipment remanufactured to like-new condition, including a 101-point quality check, OEM calibration, the same warranty as new and hardware customization options for eligible models.

Yes. Keysight Premium Used ECal modules include OEM calibration. For other used offers, check the calibration status shown in the listing. Fresh Keysight calibration can be added where available.

A mechanical VNA calibration kit uses individual calibration standards that must be connected in sequence. An electronic calibration (ECal) module uses electronically switched, individually characterized standards to simplify calibration with a single connection to the module. This reduces manual steps, connection-related variability and connector wear. Learn more in our VNA Calibration Guide.

Check the frequency range, connector type and configuration, VNA compatibility, calibration status and warranty. Also verify the condition of the precision connectors and which accessories are included with the specific offer.
