D-Coax offers RF/Microwave test services for your research
projects, as well as, production quantities tests. We have available resources and expertise in the high frequency interconnects testing that will benefit your research and products. We will work with you to make your requested tests the most accurate and reliable and we'll complete them in a timely fashion.
The following parameters can be characterized or tested to specifications with our test services:
Time Domain: Impedance, Impedance profile, rise time, propagation delay, skew and more.
Frequency Domain: S21 - Insertion loss, S11- Return loss, S12 - Reverse Insertion loss (port 2 insertion loss), S22 - Reverse Return loss (port 2 return loss) and more.
In addition to test services, D-Coax offers consulting for your research, design of a custom connector or interconnect, or a test fixture for your product, custom calibration kits, prototyping, and assembly of the products and fixtures. We also can troubleshoot your prototype or product to find the weak points of the design and engineer solutions for the desired fidelity. With our tool room quality machine shop the prototypes of new products or the modification of products, needing optimization, can be accomplished very quickly.
D-COAX has the following testing capabilities:
Frequency Domain; bandwidth 40MHz – 65GHz

D-COAX can provide the test results in the following data formats:
1. Quick data (no report):
• Anritsu 40MHz -65GHz Vector Network Analyzer data: .BMP (waveform capture),
.TAB (tabulated data), .S2P (used for touchstone modeling program)
• Tektronix DSA8200 data: .BMP files (screen capture with set measurements or specifications)
2. Full report: description of test setup, drawings, diagrams, waveforms as necessary, data analysis,
raw data, Pass/Fail spec determination, summary, conclusion
The VNA data has the measurements of:
S21: Insertion loss
S11: Return loss
S12: Reverse Insertion loss (port 2 insertion loss)
S22: Reverse Return loss (port 2 return loss)
The VNA graph types are: Log Magnitude, Phase, Smith Chart (impedance), SWR, Group Delay, Smith Chart (admittance), Linear Polar, Log Polar, Linear Magnitude, Real, Imaginary.
The TDR has measurements of mV, rho and Ohms versus time that can be used in the reflection or transmission modes. The TDR measurement set is:
- Amplitude Measurements (Amplitude, High, Low, Min, Max, Mid, +Overshoot, -Overshoot and more)
- Timing Measurements (Rise Time, Fall Time, Delay, Jitter, Crossing (%, Level, Time) and more)
- The impedance can be tested to the set specifications or characteristic impedance can be calculated
for from the impedance profile.
The raw data can be transmitted electronically or on CD, the full report is a PDF document which can be
Note: The calibration is for the 1.85mm or 2.92mm calibration kit which the phase and
magnitude are zero at the reference plane.
In the case where the DUT connector has no calibration kit available, the calibration
will be performed at the reference plane where the calibration standards are connected, but will
INCLUDE the adapters in the device under test (DUT) data.
When D-COAX is in the process of building adapters, fixtures, calibration kits,
calibration coefficients, etc., D-COAX will charge for that time at the D-COAX listed rates,
but D-COAX owns these devices unless prior arrangements have been made before the work begins.
Different rates apply for devices for sale and are quoted upon request.
The testing at D-COAX is done using some of the best equipment available with the most accuracy, repeatability, and affordability in mind. But it does not stop there because many services provided by D-COAX are not available at competitive Labs. Engineering services are available for the characterization and optimization of your product. We can assist you with the conceptual design, actually machining and testing the prototype and all the way through to the fine tuning and final design of the product.
There are common roadblocks encountered during new product design and the expert staff at D-COAX will help you overcome each obstacle.
