Tool-free access
Four knurled screws allow the fixture to open and close without additional tools, making probe insertion and removal straightforward.
CF 9651 Current Clamp Calibration Fixture
Current Clamp Calibration Fixture
A defined fixture for repeatable current-clamp measurements.
The CF 9651 supports transfer-impedance and insertion-impedance measurements of SW 9600 Bx and SW 9601 Ax current clamps, plus other probes with comparable dimensions. Its aluminum enclosure and centered conductor provide a repeatable mechanical arrangement.

2 × N femaleCoaxial connections
32 mmCentering-sleeve diameter
Product overview
Position the probe. Close the fixture.
Defined conductor position
A low-permittivity centering sleeve positions the clamp around the inner conductor. The conductor diameter is 12 mm and the sleeve diameter is 32 mm.
Two measurement roles
Use the fixture for transfer-impedance or insertion-impedance measurements. Female N connectors are fitted at both ends for coaxial connections.
Application details
Check the mechanical fit
Supported clamp families
The manufacturer specifically lists SW 9600 Bx and SW 9601 Ax. Other current probes may be used when their dimensions are comparable.
Published probe envelope
The datasheet lists maximum current-probe dimensions of 95 × 95 × 45 mm. Check the actual fit and orientation of other probe models before ordering.
Typical RF response
The supplied S21 and VSWR curves show the fixture’s frequency-dependent behavior. The usable range is 10 Hz–500 MHz; the plotted sweep begins at 0.01 MHz.
