![]() Other features: coarse frequency readout to 3 digits, or to a resolution of 1 kHz if the frequency counter feature (L to X band) is included, remote control of all bridges via the same control unit, protection against damage through user error, output power can be stepped in 1dB increments with an accuracy of typically +/- 0.2 dB from 0 dB to 60 dB, direct digital power readout in mW, W, or nW, high dynamic range AFC frequency locking, with frequency response and gain matched to the source oscillator characteristics, and finally, ultra low-noisemicrowave pre-amplifiers. When used with the large size L-band resonator, true in vivo EPR is possible. The frequency ranges from 1.05 to 1.15 GHz. The L-band bridge can provide up to 400 mW microwave power for a variety of EPR studies. ![]() ![]() (This instrument does not have in vivo imaging capabilities but it is suited to be upgraded by adding a few accessories). It has two bands: the X-band, the most common microwave frequency because it combines high sensitivity with convenient sample sizes and the L-band, for large biologicalor aqueous samples. ![]() The microwave bridge of a spectrometer produces the microwave power and detects the EPR signal: its performance greatly determines the overall specifications of a spectrometer.The eleXsys series microwave bridges incorporate the latest state-of-the-art technology to provide the highest sensitivity measurements in different frequencies for eleXsys E 500/580 systems. ![]()
