Double shielded cables for maximum signal integrity at amplifier input and output
The excellent shield attenuation of more than 85 dB allows the precise measurement of small signals, even in a very “harsh” electromagnetic environment. The extremely low shielding and contact resistance reduces signal distortions caused by currents flowing to ground (ground loops), which often cannot be avoided in the measurement setup and frequently cause problems.
Return and insertion loss – 100% tested for each individual cable
The guaranteed high-frequency characteristics of the cables of the CAB-HF1 series are verified by measuring the return loss (RL) and the insertion loss (IL) on each individual cable.
Applications
Sensitive measurements of small signals from DC to the GHz range, even with high EMI load or unfavourable grounding situation.
- Runtime measurements (LIDAR, radar, SODAR…)
- High-frequency spectroscopy and tomography (NMR, MRT, ESR …)
- Impedance spectroscopy
- Fast scanning microscopy (AFM, STM, Raman …)
- Modulation spectroscopy
Comparison of FEMTO coaxial cables
When the CAB-LN1 cables are compared to the standard RG58 coaxial cables, the CAB-LN1 cables are better suited for all frequencies up to 3 GHz. Compared to our low-noise CAB-LN1 coaxial cables, a distinction must be made between the input and output sides of the amplifiers. On the input side, the low-noise CAB-LN1 cables offer better performance up to 1 MHz. Above this frequency, FEMTO recommends the new CAB-HF1 cables.
On the output side, FEMTO recommends High Frequency CAB-HF1 cables. CAB-HF1 RF cables offer the advantages of good shielding against EM interference and good protection against unwanted ground loops. Both are important at the output.
