WITH PLTS FOR FREQUENCY DOMAIN MEASUREMENTS, WHAT IS THE TRANSITION TIME TO THE TIME DOMAIN?


图片名称
The principle of time domain transformation of PLTS and PNA and ENA-TDR are the same. The rise time is proportional to the frequency domain measurement bandwidth. The wider the measurement bandwidth, the narrower the rise time, and the more subtle time-domain impedance discontinuity can be seen. For PLTS, the nominal rise time (10/90) = 720 / FreqStopGHz, for 20 GHz measurements, the nominal rise time is 36 ps (PNA and ENA-TDR will have slightly different rise times due to the use of different window functions) . In the time domain transformation of these instruments and software, the window function is used to solve the sidelobe problem of the time domain response. The parameters of the window function can be used to adjust the size of the side lobes and the main lobe, so it can be used. To adjust the rise time within a certain range. The window function currently used by PLTS is an exponential window with a narrow rise time adjustment range. We will add a Kaiser window to PLTS2013 Update1 to provide a wide range of rise time adjustments consistent with PNA. In addition, we will also provide several window functions such as Gaussian, Hanning, Hamming, Blackman, Chebyshev for users to choose.

WHAT ARE THE ADVANTAGES OF INFRARED THERMAL IMAGING TO DETECT LEAKS?

1.Infrared thermography is a non-destructive test that does not damage and adversely affect the building itself. 2.The infrared detection operation is flexible, and it is not necessary to inspect or detect on the building, which greatly reduces the risk safety of the inspection work. 3.The powerful data acquisition function of infrared camera can save infrared image and visible image at the same time, which is convenient for accurate positioning and tracking detection of building leakage area or suspected leakage area.
