Cobalt USB Vector Network Analyzer C1409 4-Port VNA

Rental Exclusive: C1409 4-Port 9 GHz Vector Network Analyzer

The C1409 Vector Network Analyzer delivers industry-leading dynamic range and sweep speed, with all the features engineers have come to expect included standard in our software.

 

This “full rack” vector network analyzer with dimensions of 14″ x 17.3″ x 3.8″ (355 x 440 x 96 mm) and a weight of just 22 lbs. (10 kg), can be used in the laboratory and in production testing, without requiring a lot of space. The VNA can be integrated into production test system via Manufacturing Test Plug-in. Auxiliary Board Option is available on all Cobalt VNAs at the time of order (factory-installed) or as an add-on at a later date.

 

The C1409 VNA includes an RF measurement module and S4 software application which runs on Windows or Linux operating system on a PC, laptop, tablet, or x86 board computer connecting to the measurement hardware via USB interface. S4 software can be installed on multiple computers that share the use of the analyzer measurement module.

 

VNAs and ACMs are delivered with factory calibration certificates containing no uncertainty data. The add-on option for ISO17025/Z540-1 Accredited, Traceable Calibration Certificate and Uncertainties is available and needs to be specified at time of order.

This product is available for rental only. Copper Mountain Technologies announced an End-of-Sale (EOS) for the C1409 4-Port 9 GHz Vector Network Analyzer. This product is no longer available for purchase, and is now exclusively available to rent, as of Sep. 12, 2025. We will provide service and repair for owners of this instrument for a minimum of 3 years from the EOS date or based on parts availability.

The C1409 VNAs come with all the software features engineers have come to expect, at no additional cost. Standard software features include:

  • Linear/logarithmic sweeps with multiple trace formats
  • Power sweeps
  • Time domain and gating conversion
  • Frequency offset mode
  • Fixture simulation (embedding/de-embedding)
  • 16 independent channels with up to 16 traces each
  • Markers with marker search tools and marker math, various conversion algorithms, and limit tests for pass/fail criteria, etc.
  • Test Automation programming in LabView, Python, MATLAB, .NET, etc.

 

CMT’s Manufacturing Test plugin is available to integrate the VNA into your production test system.
