SWR ANALYSER MFJ 269CPRO [kosong]Detail Produk
MFJ 269C Pro RF Analyzers combine five basic circuits: a variable oscillator, frequency counter, frequency multiplier, 50 ohm RF-Bridge, and a 12-bit A-D converter and microcontroller. They perform a wide variety of useful antenna and RF impedance measurements, including coaxial cable loss and electrical distance to an open or short. Applications to 520 MHz allow operations through many commercial/government VHF/UHF bands.

Primarily designed for analyzing 50 ohm antenna and transmission line systems, MFJ 269Cs measure RF impedances between a few ohms and several hundred ohms. An easily accessed user-controlled Z0 setting in the function menus allows for changing SWR and other SWR functions (i.e., return loss, reflection coefficient, match efficiency, etc.) to any normalized impedance value between 5 and 600 ohms. This feature is especially useful in 75 ohm and 300 ohm antenna systems.

MFJ 269C Pro RF Analyzers also function as a non-precision signal source and frequency counter. The operating frequency range of these units extends from 0.53 to 230 MHz in nine overlapping bands and includes extended SWR measurements on 415-520 MHz. They have an extended, commercial-style cabinet for lab work (helps to protect knobs and connectors from damage or "bump" changes). They require 10 AA size batteries for portable operation (sold separately).

MFJ 269C Pro RF Analyzers offer a great set of functions over an extensive range of frequencies. When you need a professional antenna-analyzing instrument with maximum capabilities, order one of these MFJ 269C Pro RF Analyzers,

SWR ANALYSER MFJ 259CM (kosong)

SWR ANALYSER MFJ 259CM
HF/VHF/220 MHZ,470-940KHZ,1-230 MHZ
TERBARU , READY STOK

MFJ 259CM 470 KHz - 230 MHz SWR Analyzers are compact, battery-powered RF impedance analyzers. In anticipation of the pending 600 meter US Amateur Radio allocation, and to include coverage of existing marine MW, the MFJ 259CM's lowest band covers from 470 to 940 kHz.

MFJ 259CMs combine four basic circuits; a 0.47-230 MHz variable frequency oscillator, a frequency counter, a 50 ohm RF-bridge, and an 8-bit micro-controller. These analyzers make a wide variety of useful antenna or impedance measurements, including coaxial cable loss and distance to an open or short. Although primarily designed for analyzing 50 ohm antenna and transmission line systems, MFJ 259CM HF/VHF SWR analyzers also measure RF impedances between a few ohms and several hundred ohms.

They also function as a signal source and frequency counter! Their frequency range of impedance measurement is 0.47 to 230 MHz in several overlapping bands. The accuracy of the analyzers is enhanced by the use of special microwave zero-bias Schottky detectors with matching compensating diodes. They are compensated to provide the best possible linearity with both high and low impedance loads, making the A/D converter's 0.5 percent resolution the primary limitation.

Unlike MFJ's 259B Antenna Analyzers, these new "CM" versions have two frequency-range knobs to allow wider control. The new lower-frequency coverage allows analysis of 160 and 600 meter antennas as well as Medium Wave (AM broadcast) and MW marine (medium wave) frequencies. The inclusion of 220 MHz band coverage is also a very worthwhile addition!
