The dielectric coefficient along the flat-band cable is measured with a time domain reflectometer (TDR) at high frequencies, and with a low frequency impedance analyzer. The performance of the sensor system has been tested during two winter seasons (2001-2003) at a high alpine test site in ...
A segmented, electro-mechanical, remotely controlled programmable impedance tuner for the frequency range between 10 and 200 MHz uses a cascade of three continuously variable mechanical capacitors interconnected by a set of two low loss flexible or semi-rigid cables; the electrical length of the ...

Screenshots of the measured frequency response on a network analyzer of the same FDLR2 device showing the Q loading due to its parasitic resistance because of low motional impedance for a low and b high polarization voltages. c FDLR1 measured at 167.1 MHz, showing a high Q of 48 k ...
To meet the dielectric performance requirements of terminal electronic devices in the fields of high frequency and high speed signal transmission network in the future, the preparation of polymer materials with low dielectric constant and low dielectric loss has become a hot research direction in this...
Impedance analyzer (4294 A, Agilent, USA) was used to measure the dielectric permittivity, dielectric loss and conductivity of the PVC composites at room temperature in the frequency range of 40~107 Hz. A universal tensile testing machine (UTM2202, SUNS, China) was used to test their ...

When performing low-frequency noise measurements on low-impedance electron devices, transformer coupling can be quite effective in reducing the contribution of the equivalent input noise voltage of the preamplifier to the background noise of the system. However, noise measurements on electron devices ar...
Noise rejection is accomplished by using the integrating A/D converter to attenuate noise at specific frequencies (usually 50 and 60Hz) while passing low frequency or DC normal mode signals. As shown in Figure 1-5, normal mode noise is an error signal that adds to the desired input ...
